[0.15.0] - 2024-03-24
Added
    Add horizontal scrolling to response body (#111)
        Use shift+left and shift+right
    Add app version to help modal
    Add "Copy as cURL" action to recipe menu (#123)

    Add pane for rendered request
    Show response size in Response pane (#129)

Changed
    Run prompts while rendering request URL/body to be copied
    Improve UI design of profile pane
    Show raw bytes for binary responses

Fixed
    Reset response body query when changing recipes (#133)

0.2.6
* Make list tightness match the reference implementation closer (#150,
  Michael Howell). This solves the problem where blank lines in the middle
  of a list are attributed to the list itself instead of the item, making
  its parent list become spuriously loose.
* Fix bug with entities inside link destinations (#149). The bug affects
  cases like this: [link](\!); the backslash escape was being ignored
  here.
* Commonmark.Entity: export pEntity [API change].

0.2.5.1
* Replace source with search in list of block tags. This is a spec 0.31
  change that was forgotten in the last release.

0.2.5
* Fix HTML comment parser to conform to 0.31.2 spec.
* Update spec.txt tests to commonmark-spec 0.31.2.
* Match HTML declaration blocks with lowercase letters (Michael Howell).
* Specifically track the position where enders end (Michael Howell).

0.2.4.1
* Commonmark.Html: Add aria-hidden, d, and viewBox to allowed attributes
  list.
* Correctly merge list blanks with non-list blanks (#133, Michael Howell).
* Do not look for backslashed hard breaks in link titles (#130, Michael
  Howell).
* Work around ghc bug with -K RTS options, to set the stack space properly
  for tests (#129). See https://gitlab.haskell.org/ghc/ghc/-/issues/10445.
* Revert block state completely if lazy line (#126). This fixes an issue
  with lazily-wrapped footnotes.
* Avoid adding trailing newline to list block if it's already there
  (Michael Howell). This fixes tight/loose classification in a few cases.
* Fix incorrectly parsing links with nested [] (Michael Howell).

# wk 0.9.4

- Ensure package tests pass against sf 1.0-18 (#224, #225).

# wk 0.9.3

- Ensure package compiles with `STRICT_R_HEADERS=1` (#222).

# wk 0.9.2

- Add `wk_crs()` and `wk_set_crs()` methods for `bbox` (#213)
- Fix wk_trans inconsistent meta flags handling (#217)
- Ensure package builds on arm64 for Windows (#220)

# wk 0.9.1

- Fix format strings/arguments for R-devel (#209).

# wk 0.9.0

## Breaking changes

- The common well-known binary representation of POINT EMPTY (i.e.,
  POINT (nan nan)) is now handled as POINT EMPTY allowing empty points
  to roundtrip through `wkb()` vectors (#196, #204).
- `xy(NA, NA)` is now read as a null feature instead of POINT EMPTY. This
  preserves the invariant that null features can also be identified using
  `is.na()` (#205).
- `xy(NaN, NaN)` is now read as POINT EMPTY and `is.na(xy(NaN, NaN))`
  now returns `FALSE`. This means that both EMPTY and null points can roundtrip
  through `xy()` (#205).

## Bugfixes and improvements

- `wk_meta()` now contains a new column `is_empty`, which is `TRUE`
  for any feature that contains at least one non-empty coordinate. This allows
  more efficient detection of features with zero coordinates (#197, #199).
- Updated PROJ data to use the latest pull of the database packaged with
  PROJ 9.3.0 (#201).
- The wk package now compiles once again on gcc 4.8 (#203, #206).
- Fixed `sfc_writer()` to correctly attach the `classes` attribute to
  sfc output with mixed geometry types (#195).
- Function `sfc_writer()` now has an argument `promote_multi` to write any
  input as the MULTI variant. This makes it more likely that an input vector
  will be read as a single geometry type (#198).
- The `wk_collection_filter()` now correctly increments the `part_id` when
  calling the child handler (@brownag, #194).

# wk 0.8.0

* Added `wkb_to_hex()` (@anthonynorth, #183).
* Implemented `vctrs::vec_proxy_equal()` for `wkb()` vctrs
  (@anthonynorth, #183).
* Fixed `sfc_writer()`, which had returned NULL for some inputs
  (e.g., via `wk_collection()`) (@anthonynorth, #182, #186).
* Added `wk_clockwise()` and `wk_counterclockwise()` to re-wind polygon rings
  (@anthonynorth, #188).
* New replacement-function mode for `wk_coords<-()` for in-place modification
  of coordinates (@mdsumner, #187).
* New function `wk_trans_explicit()` migrated from crs2crs (@mdsumner, #187).

# wk 0.7.3

* Fix tests for updated waldo package (#178).

# wk 0.7.2

* Fix use-after-free warnings.

# wk 0.7.1

* Fix implicit reliance on error `as.data.frame.default()`,
  which no longer occurs in r-devel (#166).

# wk 0.7.0

* Remove legacy headers that are no longer used by any downstream package
  (#146).
* `validate_wk_wkt()` now errors for an object that does not inherit from
  'wk_wkt' (#123, #146).
* Added `wk_crs_projjson()` to get a JSON representation of a CRS object.
  To make lookup possible based on shortcut-style CRS objects (e.g.,
  `"EPSG:4326"` or `4326`), added data objects `wk_proj_crs_view` and
  `wk_proj_crs_json` that contain cached versions of rendered PROJJSON
  based on the latest PROJ version (#147).
* Added a `wk_crs_proj_definition()` method for `wk_crs_inherit()` (#136,
  #147).
* Conversion to sf now uses the `sfc_writer()` for all wk classes, making
  conversions faster and fixing at least one issue with conversion of NA
  geometries to sf (#135).
* `wk_plot()` now plots `NULL`/`NA` geometries and mixed geometry types
  more reliably (#142, #143, #149).
* Exported EMPTY geometries to well-known text now include dimension
  (e.g., `POINT Z EMPTY`) (#141, #150).
* Fixed bug where `wk_polygon()` doubled some points when the input contained
  closed rings (#134, #151).
* Fixed bug where `wk_count()` exposed uninitialized values for empty input
  (#139, #153).
* The `xy_writer()` now opportunistically avoids allocating vectors for Z
  or M values unless they are actually needed (#131, #154).
* Added example WKT for all geometry types and dimensions plus helper
  `wk_example()` to access them and set various properties (#155).
* Fixes warnings when compiling with `-Wstrict-prototypes` (#157, #158).
* Removed `wk_chunk_map_feature()` in favour of using chunking strategies
  directly (#132, #159).
* Optimized `wk_coords()` for `xy()` objects (#138, #160).
* Added accessor methods for record-style vectors: `rct_xmin()`, `rct_xmax()`,
  `rct_ymin()`, `rct_ymax()`, `rct_width()`, `rct_height()`, `crc_center()`,
  `crc_x()`, `crc_y()`, `crc_r()`, `xy_x()`, `xy_y()`, `xy_z()`, and `xy_m()`
  (#144, #161).
* Added rectangle operators `rct_intersects()`, `rct_contains()`,
  and `rct_intersection()` (#161).

# wk 0.6.0

* Fixed `wk_affine_rescale()` to apply the translate and scale
  operations in the correct order (#94).
* Add `wk_handle_slice()` and `wk_chunk_map_feature()` to support
  a chunk + apply workflow when working with large vectors (#101, #107).
* C and R code was rewritten to avoid materializing ALTREP vectors
  (#103, #109).
* Added a `wk_crs_proj_definition()` generic for foreign CRS objects
  (#110, #112).
* Added `wk_crs_longlat()` helper to help promote authority-compliant
  CRS choices (#112).
* Added `wk_is_geodesic()`, `wk_set_geodesic()`, and argument `geodesic`
  in `wkt()` and `wkb()` as a flag for objects whose edges must
  be interpolated along a spherical/ellipsoidal trajectory (#112).
* Added `sf::st_geometry()` and `sf::st_sfc()` methods for wk geometry
  vectors for better integration with sf (#113, #114).
* Refactored well-known text parser to be more reusable and faster
  (#115, #104).
* Minor performance enhancement for `is.na()` and `validate_wk_wkb()`
  when called on a very long `wkb()` vector (#117).
* Fixed issue with `validate_wk_wkb()` and `validate_wk_wkt()`, which failed
  for most valid objects (#119).
* Added `wk_envelope()` and `wk_envelope_handler()` to compute feature-wise
  bounding boxes (#120, #122).
* Fixed headers and tests to pass on big endian systems (#105, #122).
* Incorporated the geodesic attribute into vctrs methods, data frame
  columns, and bbox/envelope calculation (#124, #125).
* Fix `as_xy()` for nested data frames and geodesic objects (#126, #128).
* Remove deprecated `wkb_problems()`, `wkt_problems()`, `wkb_format()`,
  and `wkt_format()` (#129).
* `wk_plot()` is now an S3 generic (#130).

# wk 0.5.0

* Fixed bugs relating to the behaviour of wk classes as
  vectors (#64, #65, #67, #70).
* `crc()` objects are now correctly exported as polygons
  with a closed loop (#66, #70).
* Added `wk_vertices()` and `wk_coords()` to extract individual
  coordinate values from geometries with optional identifying
  information. For advanced users, the `wk_vertex_filter()`
  can be used as part of a pipeline to export coordinates
  as point geometries to another handler (#69, #71).
* Added `wk_flatten()` to extract geometries from collections.
  For advanced users, the `wk_flatten_filter()` can be used as
  part of a pipeline (#75, #78).
* `options("max.print")` is now respected by all vector classes
  (#72, #74).
* Moved implementation of plot methods from wkutils to wk to
  simplify the dependency structure of both packages (#80, #76).
* Added `wk_polygon()`, `wk_linestring()`, and `wk_collection()`
  to construct polygons, lines, and collections. For advanced
  users, `wk_polygon_filter()`, `wk_linestring_filter()`, and
  `wk_collection_filter()` can be used as part of a pipeline
  (#77, #84).
* Added a C-level transform struct that can be used to simplify
  the the common pattern of transforming coordinates. These
  structs can be created by other packages; however, the
  `wk_trans_affine()` and `wk_trans_set()` transforms are
  also built using this feature. These are run using the
  new `wk_transform()` function and power the new
  `wk_set_z()`, `wk_set_m()`, `wk_drop_z()`, `wk_drop_m()`,
  functions (#87, #88, #89).

# wk 0.4.1

* Fix LTO and MacOS 3.6.2 check errors (#61).

* Use new C API in favour of header-only approach for all
  wk functions (#19, #22).
* Use cpp11 to manage safe use of callables that may longjmp
  from C++.
* Vector classes now propagate `attr(, "crs")`, and check
  that operations that involve more than one vector have
  compatable CRS objects as determined by `wk_crs_equal()`.
* Added an R-level framework for other packages to implement
  wk readers and handlers: `wk_handle()`, `wk_translate()`,
  and `wk_writer()` (#37).
* Added a native reader and writer for `sf::st_sfc()` objects
  and implemented R-level generics for sfc, sfg, sf, and bbox
  objects (#28, #29, #38, #45).
* Implement `crc()` vector class to represent circles (#40).
* Added a 2D cartesian bounding box handler (`wk_bbox()`) (#42).
* Refactored unit tests reflecting use of the new API and
  for improved test coverage (#44, #45, #46).
* Added `wk_meta()`, `wk_vector_meta()`, and `wk_count()` to
  inspect properties of vectors (#53).
* Modified all internal handlers such that they work with vectors
  of unknown length (#54).

# wk 0.3.4

* Fixed reference to `wkutils::plot.wk_wksxp()`, which
  no longer exists.

# wk 0.3.3

* Fixed WKB import of ZM geometries that do not use EWKB.

Snowball 3.0.1 (2025-05-09)
===========================

Python
------

* The __init__.py in 3.0.0 was incorrectly generated due to a missing
  build dependency and the list of algorithms was empty.  First reported by
  laymonage.  Thanks to Dmitry Shachnev, Henry Schreiner and Adam Turner for
  diagnosing and fixing.  (#229, #230, #231)

* Add trove classifiers for Armenian and Yiddish which have now been registered
  with PyPI.  Thanks to Henry Schreiner and Dmitry Shachnev.  (#228)

* Update documented details of Python 2 support in old versions.

Snowball 3.0.0 (2025-05-08)
===========================

Ada
---

* Bug fixes:

  + Fix invalid Ada code generated for Snowball `loop` (it was partly Pascal!)
    None of the stemmers shipped in previous releases triggered this bug, but
    the Turkish stemmer now does.

  + The Ada runtime was not tracking the current length of the string
    but instead used the current limit value or some other substitute, which
    manifested as various incorrect behaviours for code inside of `setlimit`.

  + `size` was incorrectly returning the difference between the limit and the
    backwards limit.

  + `lenof` or `sizeof` on a string variable generated Ada code that didn't
    even compile.

  + Fix incorrect preconditions on some methods in the runtime.

  + Fix bug in runtime code used by `attach`, `insert`, `<-` and string
    variable assignment when a (sub)string was replaced with a larger string.
    This bug was triggered by code in the Kraaij-Pohlmann Dutch stemmer
    implementation (which was previously not enabled by default but is now the
    standard Dutch stemmer).

  + Fix invalid code generated for `insert`, `<-` and string variable
    assignment.  This bug was triggered by code in the Kraaij-Pohlmann
    Dutch stemmer implementation (which was previously not enabled by default
    but is now the standard Dutch stemmer).

  + Generate valid code for programs which don't use `among`.  This didn't
    affect code generation for any algorithms we currently ship.

  + If the end of a routine was unreachable code the Snowball compiler
    would think the start of the next routine was also unreachable and would
    not generate it.  This didn't affect code generation for any algorithms we
    currently ship.

* Code quality:

  + Only declare variables A and C when each is needed.

  + Fix indentation of generated declarations.

  + Drop extra blank line before `Result := True`.

C/C++
-----

* Bug fixes:

  + Fix potential NULL dereference in runtime code if we failed to allocate
    memory for the p or S member for a Snowball program which uses one or more
    string variables.  Problem was introduced in Snowball 2.0.0.  Fixes #206,
    reported by Maxim Korotkov.

  + Fix invalid C code generated when a failure is handled in a context with
    the opposite direction to where it happened, for example:

        externals (stem)
        define stem as ( try backwards 'x' )

    This was fixed by changing the C generator to work like all the other
    generators and pre-generate the code to handle failure.

  + Eliminate assumptions that NULL has all-zero bit pattern.  We don't know
    of any current platforms where this assumption fails, but the C standard
    doesn't require an all-zero bit pattern for NULL.  Fixes #207.

* Optimisations:

  + Store index delta for among substring_i field.  This makes trying
    substrings after a failed match slightly faster because we can just add
    the offset to the pointer we already have to the current element.

* Code quality:

  + Improve formatting of generated code.

C#
--

* Bug fixes:

  + Add missing runtime support for testing for a string var at the current
    position when working forwards.  This situation isn't exercised by any of
    the stemming algorithms we currently ship.

  + Adjust generated code to work around a code flow analysis bug in the `mcs`
    C# compiler.

* Code quality:

  + Prune unused `using System.Text;`.

  + Generate C# with UTF-8 source encoding.  This makes the generated code
    easier to follow, which helps during development.  It's also a bit smaller.
    For now codepoints U+0590 and above are still emitted as escape sequences
    to avoid confusing source code rendering when LTR scripts are involved.

Go
--

* Optimisations:

  + Drop some unneeded Go code generated for string `$`.  None of the shipped
    stemmers use string `$`, though the Schinke Latin stemmer algorithm on the
    website does.

* Code quality:

  + Dispatch among result with `switch` instead of an `if` ... `else if` chain
    (which looks like we did because the Go generator evolved from the Python
    generator and Python didn't used to have a switch-like construct.  This
    doesn't make a measurable speed difference so it seems the Go compiler is
    optimising both to equivalent code, but using a switch here seems clearer,
    a better match for the intent, and is a bit simpler to generate.

  + Generate Go with UTF-8 source encoding.  This makes the generated code
    easier to follow, which helps during development.  It's also a bit smaller.
    For now codepoints U+0590 and above are still emitted as escape sequences
    to avoid confusing source code rendering when LTR scripts are involved.

Java
----

* The Java code generated by Snowball requires now requires Java >= 7.  Java 7
  was released in 2011, and Java 6's EOL was 2013 so we don't expect this
  to be a problematic requirement.  See #195.

* Optimisations:

  + We now store the current string in a `char[]` rather than using a
    `StringBuilder` to reduce overheads.  The `getCurrent()` method continues
    to return a Java `String`, but the `char[]` can be accessed using the new
    `getCurrentBuffer()` and `getCurrentBufferLength()` methods.  Patch from
    Robert Muir (#195).

  + Use a more efficient mechanism for calling `among` functions.  Patch from
    Robert Muir (#195).

* Code quality:

  + Consistently put `[]` right after element type for array types, which seems
    the most used style.

  + Fix javac warnings in SnowballProgram.java.

  + Improve formatting of generated code.

Javascript
----------

* Bug fixes:

  + Use base class specified by `-p` in string `$` rather than hard-coding
    `BaseStemmer` (which is the default if you don't specify `-p`).  None of
    the shipped stemmers use string `$`, though the Schinke Latin stemmer
    algorithm on the website does.

* Code quality:

  + Modernise the generated code a bit.  Loosely based on changes proposed in
    #123 by Emily Marigold Klassen.

* Other changes:

  + The Javascript runner is now specified by make variable `JSRUN` instead
    of `NODE` (since node is just one JS implementation).  The default value
    is now `node` instead of `nodejs` (older Debian and Ubuntu packages used
    `/usr/bin/nodejs` because `/usr/bin/node` was already in use by a
    completely different package, but that has since changed).

Pascal
------

* Bug fixes:

  + Add missing semicolons to code generated in some cases for a function which
    always succeeds or always fails.  The new dutch.sbl was triggering this
    bug.

  + If the end of a routine was unreachable code the Snowball compiler
    would think the start of the next routine was also unreachable and would
    not generate it.  This didn't affect code generation for any algorithms we
    currently ship.

* Code quality:

  + Eliminate commented out code generated for string `$`.  None of the shipped
    stemmers use string `$`, though the Schinke Latin stemmer algorithm on the
    website does.

* Other changes:

  + Enable warnings, etc from fpc.

  + Select GNU-style diagnostic format.

Python
------

* Optimisations:

  + Use Python set for grouping checks.  This speeds up running the Python
    testsuite by about 4%.

  + Routines used in `among` are now referenced by name directly in the
    generated code, rather than using a string containing the name.  This
    avoids a `getattr()` call each time an among wants to call a routine.  This
    doesn't seem to make a measurable speed difference, but it's cleaner and
    avoids problems with name mangling.  Suggested by David Corbett in #217.

  + Simplify code generated for `loop`.  If the iteration count is constant and
    at most 4 then iterate over a tuple which microbenchmarking shows is
    faster.  The only current uses of loop in the shipped stemmers are `loop 2`
    so benefit from this.  Otherwise we now use `range(AE)` instead of
    `range (AE, 0, -1)` (the actual value of the loop variable is never
    used so only the number of iterations matter).

* Bug fixes:

  + Correctly handle stemmer names with an underscore.

* Code quality:

  + Generate Python with UTF-8 source encoding.  This makes the generated code
    easier to follow, which helps during development.  It's also a bit smaller.
    For now codepoints U+0590 and above are still emitted as escape sequences
    to avoid confusing source code rendering when LTR scripts are involved.

* Other changes:

  + Set python_requires to indicate to install tools that the generated code
    won't work with Python 3.0.x, 3.1.x and 3.2.x (due to use of `u"foo"`
    string literals).  Closes #192 and #191, opened by Andreas Maier.

  + Add classifiers to indicate support for Python 3.3 and for 3.8 to 3.13.
    Fixes #158, reported by Dmitry Shachnev.

  + Stop marking the wheel as universal, which had started to give a warning
    message.  Patch from Dmitry Shachnev (#210).

  + Stop calling `setup.py` directly which is deprecated and now produces a
    warning - use the `build` module instead.  Patch from Dmitry Shachnev
    (#210).

Rust
----

* Optimisations:

  + Shortcut unnecessary calls to find_among, porting an optimization from the
    C generator.  In some stemming benchmarks this improves the performance
    of the rust english stemmer by about 27%.  Patch from jedav (#202).

* Code quality:

  + Suppress unused_parens warning, for example triggered by the code generated
    for `$x = x*x` (where `x` is an integer).

  + Dispatch `among` result with `match` instead of an `if` ... `else if` chain
    (which looks like we did because the Rust generator evolved from the Python
    generator and Python didn't used to have a switch-like construct.  This
    results in a 3% speed-up for an unoptimised Rust compile but doesn't seem
    to make a measurable difference when optimising so it seems the Rust
    compiler is optimising both to equivalent code.  However using a `match`
    here seems clearer, a better match for the intent, and is a bit simpler to
    generate.

  + Generate Rust with UTF-8 source encoding.  This makes the generated code
    easier to follow, which helps during development.  It's also a bit smaller.
    For now codepoints U+0590 and above are still emitted as escape sequences
    to avoid confusing source code rendering when LTR scripts are involved.

New stemming algorithms
-----------------------

* Add Esperanto stemmer from David Corbett (#185).

* Add Estonian algorithm from Linda Freienthal (#108).

Behavioural changes to existing algorithms
------------------------------------------

* Dutch: Switch to Kraaij-Pohlmann as the default for Dutch.  In case you
  want Martin Porter's Dutch stemming algorithm for compatibility, this is now
  available as `dutch_porter`.  Fixes #1, reported by gboer.

* Dutch (Kraaij-Pohlmann): Fix differences between the Snowball implementation
  and the original C implementation.

* Dutch (Kraaij-Pohlmann): Add a small number of exceptions to the Snowball
  implementation to avoid unwanted conflations.  This addresses all cases so
  far identified which Martin's Dutch stemmer handled better.  Fixes #208.

* Dutch (Porter): The "at least 3 characters" part of the R1 definition was
  actually implemented such that when working in UTF-8 it was "at least 3
  bytes".  We stripped accents normally found in Dutch except for `è` before
  setting R1, and no Dutch words starting `è` seem to stem differently
  depending on encoding, but proper nouns and other words of foreign origin may
  contain other accented characters and it seems better for the stemmer to
  handle such words the same way regardless of the encoding in use.

* English: Replace '-ogist' with '-og' to conflate "geologist" and "geology", etc.
  Suggested by Marc Schipperheijn on snowball-discuss.

* English: Add extra condition to undoubling.  We no longer undouble if the
  double consonant is preceded by exactly "a", "e" or "o" to avoid conflating
  "add"/"ad", "egg"/"eg", "off"/"of", etc.  Fixes #182, reported by Ed Page.

* English: Avoid conflating 'emerge' and 'emergency'.  Reported by Frederick Ross
  on snowball-discuss.

* English: Avoid conflating 'evening' and 'even'.  Reported by Ann B on
  snowball-discuss.

* English: Avoid conflating 'lateral' and 'later'.  Reported by Steve Tolkin on
  snowball-discuss.

* English: Avoid conflating 'organ', 'organic' and 'organize'.

* English: Avoid conflating 'past' and 'paste'.  Reported by Sonny on
  snowball-discuss.

* English: Avoid conflating 'universe', 'universal' and 'university'.  Reported
  by Clem Wang on snowball-discuss.

* English: Handle -eed and -ing exceptions in their respective rules.
  This avoids the overhead of checking for them for the majority of
  words which don't end -eed or -ing.  It also allows us to easily handle
  vying->vie and hying->hie at basically no extra cost.  Reduces the time to
  stem all words in our English word list by nearly 2%.

* French: Remove elisions as first step.  See #187.  Originally reported by
  Paul Rudin and kelson42.

* French: Remove -aise and -aises so for example, "française" and "françaises"
  are now conflated with "français".  Fixes #209.  Originally reported by
  ririsoft and Fred Fung.

* French: Avoid incorrect conflation of `mauvais` (bad) with `mauve` (mauve,
  mallow or seagull); avoid conflating `mal` with `malais`, `pal` with
  `palais`, etc.

* French: Avoid conflating `ni` (neither/nor) with `niais`
  (inexperienced/silly) and `nie`/`nié`/`nier`/`nierais`/`nierons` (to deny).

* French: -oux -> -ou.  Fixes #91, reported by merwok.

* German: Replace with the "german2" variant.  This normalises umlauts ("ä" to
  "ae", "ö" to "oe", "ü" to "ue") which is presumably much less common in
  newly created text than it once was as modern computer systems generally
  don't have the limitations which motivated this, but there will still be
  large amounts of legacy text which it seems helpful for the stemmer to
  handle without having to know to select a variant.

  On our sample German vocabulary which contains 35033 words, 77 words give
  different stems.  A significant proportion of these are foreign words, and
  some are proper nouns.  Some cases definitely seem improved, and quite a few
  are just different but effectively just change the stem for a word or group
  of words to a stem that isn't otherwise generated.  There don't seem any
  changes that are clearly worse, though there are some changes that have both
  good and bad aspects to them.

  Fixes #92, reported by jrabensc.

* German: Don't remove -em if preceded by -syst to avoid overstemming words
  ending -system.  This change means we now conflate e.g. "system" and
  "systemen".  Partly addresses #161, reported by Olga Gusenikova.

* German: Remove -erin and -erinnen suffixes which conflates singular and
  plural female versions of nouns with the male versions.  Fixes #85 and
  partly addresses #161, reported by Olga Gusenikova.

* German: Replace -ln and -lns with -l.  This improves 82 cases in the current
  sample data without making anything worse.  Tests on a larger word list look
  good too.  Partly addresses #161, reported by Olga Gusenikova.

* German: Remove -et suffix when we safely can.  Fixes #200, reported by Robert
  Frunzke.

* Greek: Fix "faulty slice operation" for input `ισαισα`.  The fix changes
  `ισα` to stem to `ισ` instead of the empty string, which seems better (and to
  be what the second paper actually says to do if read carefully).  Fixes #204,
  reported by subnix.

* Italian: Address overstemming of "divano" (sofa) which previously stemmed to
  "div", which is the stem for 'diva' (diva).  Now it is stemmed to 'divan',
  which is what its plural form 'divani' already stemmed to.  Fixes #49,
  reported by francesco.

* Norwegian: Improve stemming of words ending -ers.  Fixes #175, reported by
  Karianne Berg.

* Norwegian: Include more accented vowels - treating "ê", "ò", "ó" and "ô"
  as vowels improves the stemming of a fairly small number of words, but
  there's basically no cost to having extra vowels in the grouping, and some
  of these words are commonly used.  Fixes #218, reported by András Jankovics.

* Romanian: Fix to work with Romanian text encoded using the correct Unicode
  characters.  Romanian uses a "comma below" diacritic on letters "s" and "t"
  ("ș" and "ț").  Before Unicode these weren't easily available so Romanian
  text was written using the visually similar "cedilla" diacritic on these
  letters instead ("ş" and "ţ").  Previously our stemmer only recognised the
  latter.  Now it maps the cedilla forms to "comma below" as a first step.
  Patch from Robert Muir.

* Spanish: Handle -acion like -ación and -ucion like -ución.  It's apparently
  common to miss off accents in Spanish, and there are examples in our test
  vocabulary that these change helps.  Proposed by Damian Janowski.

* Swedish: Replace suffix "öst" with "ös" when preceded by any of 'iklnprtuv'
  rather than just 'l'.  The new rule only requires the "öst" to be in R1
  whereas previously we required all of "löst" to be.  This second tweak
  doesn't seem to affect any words ending "löst" but it conflates a few extra
  cases when combined with the expanded list of preceding letters, and seems
  more logical linguistically (since "ös" is akin to "ous" in English).  Fixes
  #152, reported by znakeeye.

* Swedish: Remove -et/-ets in cases where it helps.  Removing -et can't be done
  unconditionally because many words end in -et where this isn't a suffix.
  However it's a very common suffix so it seems worth crafting a more complex
  condition under which to remove.  Fixes #47.

* Turkish: Remove proper noun suffixes.  For example, `Türkiye'dir` ("it is
  Turkey") is now conflated with `Türkiye` ("Turkey").  Fixes #188.

* Yiddish: Avoid generating empty stem for input "גע" (not a valid word, but
  it's better to avoid an empty stem for any non-empty input).

Optimisations to existing algorithms
------------------------------------

* General change: Use `gopast` everywhere to establish R1 and R2 as it is a
  little more efficient to do so.

* Basque: Use an empty action rather than replacing the suffix with itself
  which seems clearer and is a little more efficient.

* Dutch (Porter): Optimise prelude routine.

* English: Remove unnecessary exception for `skis` as the algorithm stems
  `skis` to `ski` by itself (`skies` and `sky` do still need a special case to
  avoid conflation with `ski` though).

* Hungarian: We no longer take digraphs into account when determining where R1
  starts.  This can only make a difference to the stemming if we removed a
  suffix that started with the last character of the digraph (or with "zs" in
  the case of "dzs"), and that doesn't happen for any of the suffixes we remove
  for any valid Hungarian words.  This simplification speeds up stemming by
  ~2% on the current sample vocabulary list.  See #216.  Thanks to András
  Jankovics for confirming no Hungarian words are affected by this change.

* Lithuanian: Remove redundant R1 check.

* Nepali: Eliminate redundant check_category_2 routine.

* Tamil: Optimise by using `among` instead of long `or` chains.  The generated
  C version now takes 43% less time to processes the test vocabulary.

* Tamil: Remove many cases which can't be triggered due to being handled by
  another case.

* Tamil: Clean up some uses of `test`.

* Tamil: Make `fix_va_start` simpler and faster.

* Tamil: Localise use of `found_a_match` flag.

* Tamil: Eliminate pointless flag changes.

* Turkish: Minor optimisations.

Code clarity improvements to existing algorithms
------------------------------------------------

* Stop noting dates changes were made in comments in the code - we now maintain
  a changelog in each algorithm's description page on the website (and the
  version control history provides a finer grained view).

* Always use `insert` instead of `<+` as the named command seems clearer.

* English: Add comments documenting motivating examples for all exceptional
  cases.

* Lithuanian: Change to recommended latin stringdef codes.  Using common codes
  makes it easier to work across algorithms, but they are more mnemonic so also
  seem clearer when just considering this one algorithm.

* Serbian: Change to recommended latin stringdef codes.  Using common codes
  makes it easier to work across algorithms, but they are more mnemonic so also
  seem clearer when just considering this one algorithm.

* Turkish: Use `{sc}` for s-cedilla and `{i}` for dotless-i to match other
  uses.

Compiler
--------

* Generic code generation improvements:

  + Show Snowball source leafname in "generated" comment at start of files.

  + Add generic reachability tracking machinery.  This facilitates various new
    optimisations, so far the following have been implemented:

    - Tail-calling
    - Simpler code for calling routines which always give the same signal
    - Simpler code when a routine ends in a integer test (this also allows
      eliminating an Ada-specific codegen optimisation which did something
      similar but only for routines which consisted *entirely* of a single
      integer test.
    - Dead code reporting and removal (only in simple cases currently)

    Currently this overlaps in functionality with the existing reachability
    tracking which is implemented on a per-language basis, and only for some
    languages.  This reachability tracking was originally added for Java
    where some unreachable code is invalid and result in a compile time error,
    but then seems to have been copied for some other newer languages which
    may or may not actually need it.  The approach it uses unfortunately
    relies on correctly updating the reachability flag anywhere in the
    generator code where reachability can change which has proved to be a
    source of bugs, some unfixed.  This new approach seems better and with some
    more work should allow us to eliminate the older code.  Fixes #83.

  + Omit check for `among` failing in generated code when we can tell at
    compile time that it can't fail.

  + Optimise `goto`/`gopast` applied to a grouping or inverted grouping (which
    is by far the most common way to use `goto`/`gopast`) for all target
    languages (new for Go, Java, Javascript, Pascal and Rust).

  + We never need to restore the cursor after `not`.  If `not` turns signal `f`
    into `t` then it sets `c` back to its old position; otherwise, `not`
    signals `f` and `c` will get reset by whatever ultimately handles this `f`
    (or the program exits and the position of `c` no longer matters).  This
    slightly improves the generated code for the `english` and `porter`
    stemmers.

  + Don't generate code for undefined or unused routines.

  + Avoid generating variable names and then not actually using them.  This
    eliminates mysterious gaps in the numbering of variables in the generated
    code.

  + Eliminate `!`/`not` from integer test code by generating the inverse
    comparison operator instead for all languages, e.g. for Python we now
    generate

      if self.I_p1 >= self.I_x:

    instead of

      if not self.I_p1 < self.I_x:

    This isn't going to be faster in compiled languages with an optimiser but
    for scripting languages it may be faster, and even if not, it makes for a
    little less work when loading the script.

  + Canonicalise `hop 1` to `next` as the generated code for `next` can be
    slightly more efficient.  This will also apply to `hop` followed by a
    constant expression which Snowball can reduce to `1`.

  + Avoid trailing whitespace in generated files.

  + Fix problems with --comments option:

    - When generating C code we would segfault for code containing `atleast`,
      `hop` or integer tests.
    - Fix missing comments for some commands in some target languages.
    - Fix inconsistent formatting of comments in some target languages.
    - Comments in C are now always on their own line - previously some were
      after at the end of the line and some on their own line which made them
      harder to follow.
    - Emit comments before `among` and before routine/external definitions.

  + Simplify more cases of numeric expressions (e.g. `x * 1` to `x`).

* Improve --help output.

* Division by zero during constant folding now gives an error.

* For `hop` followed by an unexpected token (e.g. `hop hop`) we were
  already emitting a suitable error but would then segfault.

* Emit error for redefinition of a grouping.

* Improve errors for `define` of an undeclared name.  We already peek at the
  next token to decide whether to try to parse as a routine or grouping.
  Previously we parsed as a routine if it was `as`, and a grouping otherwise,
  but routine definitions are more common and a grouping can only start with
  a literal string or a name, so now we assume a routine definition with a
  missing `as` if the next token isn't valid for either.

* Suppress duplicate (or even triplicate) "unexpected" errors for the same
  token when the compiler tried to recover from the error by adjusting the
  parse stare and marking the token to be reparsed, but the same token then
  failed to parse in the new state.

* Fix NULL pointer dereference if an undefined grouping is used in the
  definition of another grouping.

* Fix mangled error for `set` or `unset` on a non-boolean:

  test.sbl:2: nameInvalid type 98 in name_of_type()

* Emit warning if `=>` is used.  The documentation of how it works doesn't
  match the implementation, and it seems it has only ever been used in the
  Schinke stemmer implementation (which assumes the implemented behaviour).
  We've updated the Schinke implementation to avoid it.  If you're using it
  in your own Snowball code please let us know.

* Improve errors for unterminated string literals.

* Fix NULL pointer dereference on invalid code such as `$x = $y`.

* If malloc fails while compiling the compiler will now report the failure
  and exit.  Previously the NULL return from malloc wasn't checked for so
  we'd typically segfault.

* `lenof` and `sizeof` applied to a string variable now mark the variable
  as used, which avoids a bogus error followed by a confusing additional
  message if this is the only use of that variable:

  lenofsizeofbug.sbl:3: warning: string 's' is set but never used
  Unhandled type of dead assignment via sizeof

  This is situation is unlikely to occur in real world code.

* The reported line number for "string not terminated" error was one too high
  in the case where we were in a stringdef (but correct if we weren't).

* Eliminate special handling for among starter.  We now convert the starter
  to be a command before the among, adding an explict substring if there
  isn't one.

* We now warn if the body of a `repeat` or `atleast` loop always signals
  `t` (meaning it will loop forever which is very undesirable for a stemming
  algorithm) or always signals `f` (meaning it will never loop, which seems
  unlikely to be what was intended).

* Release memory in compiler before exit.  The OS will free all allocated
  memory when a process exits, so this memory isn't actually leaked, but it can
  be annoying with when using snowball as part of a larger build process with
  some leak-finding tools.  Patch from jsteemann in #166.

* Store textual data more efficiently in memory during Snowball compilation.
  Previously almost all textual data was stored as 16 bit values, but most
  such data only uses 8 bit character values.  Doubling the memory usage
  isn't really an issue as Snowball programs are tiny, but this also
  complicated code handling such data.  Now only literal strings use the
  16 bit values.

* Fix clang -Wunused-but-set-variable warning in compiler code.

* Fix a few -Wshadow warnings in compiler and enable this warning by default.

* Tighten parsing of `writef()` format strings.  We now error out on
  unrecognised escape codes or if a numbered escape is used with too high a
  number or a non-digit.  This change reveals that the Go and Rust generators
  were using invalid escape ~A - the old writef() code was substituting this
  with just A which is what is wanted so this case was harmless but being
  lenient here could hide bugs, especially when copying code between
  generators as they don't all support the same set of format codes.

Build system
------------

* Turn on Java warnings and make them errors.

* Compile C code with -g by default.  This makes debugging easier, and
  matches the default for at least some other build systems (e.g. autotools).

* Fix "make clean" to remove all built Ada files.

* Clean `stemtest` too.  Patch from Stefano Rivera.

* Add missing `COMMON_FILES` dependency to dist targets.

* GNUmakefile: Tidy up and make more consistent

* GNUmakefile: Make use of $* to improve speed and readability.

* Use $(patsubst ...) instead of sed in .java.class rule which gives cleaner
  make output and is a bit more efficient.

* Add `WERROR` make variable to provide a way to add `-Werror` to existing
  CFLAGS.

libstemmer
----------

Testsuite
---------

* Give a clear error if snowball-data isn't found.  Fixes #196, reported by
  Andrea Maccis.

* Handle not thinning testdata better.  If THIN_FACTOR is set to 1 we no longer
  run gzipped test data through awk.  We also now handle THIN_FACTOR being set
  empty as equivalent to 1 for convenience.

* csharp_stemwords: Correctly handle a stemmer name containing an underscore.

* csharp_stemwords: Make `-i` option optional and read from stdin if omitted,
  like the C version does.

* csharp_stemwords: Process the input line by line which is more helpful for
  interactive testing, and also a little faster.

* Fix Java TestApp to allow a single argument.  The documented command line
  syntax is that you only need to specify the language and there was already
  code to read from stdin if no input file was specified, but at least two
  command line options were required.

* Fix deprecation warning in TestApp.java.

* Optimise TestApp.java by creating fewer objects.  Patch from Robert Muir.

* stemwords.py: We no longer create an empty output file if we fail to open the
  input file.

* stemwords: Improve error message to say "Out of memory or internal error"
  rather than just "Out of memory".

Documentation
-------------

* Include "what is stemming" section in each README.

* Include section on threads in each README.  Based on patch for Python from
  dbcerigo.

* Document that input should be lowercase with composed accents.  See #186,
  reported by 1993fpale.

* Add README section on building, including notes on cross-compiling.  Fixes
  #205, reported by sin-ack.

* CONTRIBUTING.rst: Clarify which charsets to list

* CONTRIBUTING.rst: Add general advice section.  In particular, note to use
  spaces-only for indentation in most cases.  Thanks to Dmitry Shachnev for
  raising this point.

* CONTRIBUTING.rst: Note that UTF-8 is OK in comments.  Thanks to Dmitry
  Shachnev for asking.

* Fix some typos.  Patch from Josh Soref.

* Document that our CI now uses github actions.

* Update link to Greek stemmer PDF.  Patch from Michael Bissett (#33).

Snowball 2.2.0 (2021-11-10)
===========================

New Code Generators
-------------------

* Add Ada generator from Stephane Carrez (#135).

Javascript
----------

* Fix generated code to use integer division rather than floating point
  division.

  Noted by David Corbett.

Pascal
------

* Fix code generated for division.  Previously real division was used and the
  generated code would fail to compile with an "Incompatible types" error.

  Noted by David Corbett.

* Fix code generated for Snowball's `minint` and `maxint` constant.

Python
------

* Python 2 is no longer actively supported, as proposed on the mailing list:
  https://lists.tartarus.org/pipermail/snowball-discuss/2021-August/001721.html

* Fix code generated for division.  Previously the Python code we generated
  used integer division but rounded negative fractions towards negative
  infinity rather than zero under Python 2, and under Python 3 used floating
  point division.

  Noted by David Corbett.

Code quality Improvements
-------------------------

* C/C++: Generate INT_MIN and INT_MAX directly, including <limits.h> from
  the generated C file if necessary, and remove the MAXINT and MININT macros
  from runtime/header.h.

* C#: An `among` without functions is now generated as `static` and groupings
  are now generated as constant.  Patches from James Turner in #146 and #147.

Code generation improvements
----------------------------

* General:

  + Constant numeric subexpressions and constant numeric tests are now
    evaluated at Snowball compile time.

  + Simplify the following degnerate `loop` and `atleast` constructs where
    N is a compile-time constant:

    - loop N C where N <= 0 is a no-op.

    - loop N C where N == 1 is just C.

    - atleast N C where N <= 0 is just repeat C.

    If the value of N doesn't depend on the current target language, platform
    or Unicode settings then we also issue a warning.

Behavioural changes to existing algorithms
------------------------------------------

* german2: Fix handling of `qu` to match algorithm description.  Previously
  the implementation erroneously did `skip 2` after `qu`.  We suspect this was
  intended to skip the `qu` but that's already been done by the substring/among
  matching, so it actually skips an extra two characters.

  The implementation has always differed in this way, but there's no good
  reason to skip two extra characters here so overall it seems best to change
  the code to match the description.  This change only affects the stemming of
  a single word in the sample vocabulary - `quae` which seems to actually be
  Latin rather than German.

Optimisations to existing algorithms
------------------------------------

* arabic: Handle exception cases in the among they're exceptions to.

* greek: Remove unused slice setting, handle exception cases in the among
  they're exceptions to, and turn `substring ... among ...  or substring ...
  among ...` into a single `substring ... among ...` in cases where it is
  trivial to do so.

* hindi: Eliminate the need for variable `p`.

* irish: Minor optimisation in setting `pV` and `p1`.

* yiddish: Make use of `among` more.

Compiler
--------

* Fix handling of `len` and `lenof` being declared as names.

  For compatibility with programs written for older Snowball versions
  len and lenof stop being tokens if declared as names.  However this
  code didn't work correctly if the tokeniser's name buffer needed to
  be enlarged to hold the token name (i.e. 3 or 5 elements respectively).

* Report a clearer error if `=` is used instead of `==` in an integer test.

* Replace a single entry command list with its contents in the internal syntax
  tree.  This puts things in a more canonical form, which helps subsequent
  optimisations.

Build system
------------

* Support building on Microsoft Windows (using mingw+msys or a similar
  Unix-like environment).  Patch from Jannick in #129.

* Split out INCLUDES from CPPFLAGS so that CPPFLAGS can now be overridden by
  the user if required.  Fixes #148, reported by Dominique Leuenberger.

* Regenerate algorithms.mk only when needed rather than on every `make` run.

libstemmer
----------

* The libstemmer static library now has a `.a` extension, rather than `.o`.
  Patch from Michal Vasilek in #150.

Testsuite
---------

* stemtest: Test that numbers and numeric codes aren't damaged by any of the
  algorithms.  Regression test for #66.  Fixes #81.

* ada: Fix ada tests to fail if output differs.  There was an extra `| head
  -300` compared to other languages, which meant that the exit code of `diff`
  was ignored.  It seems more helpful (and is more consistent) not to limit how
  many differences are shown so just drop this addition.

* go: Stop thinning testdata.  It looks like we only are because the test
  harness code was based on that for rust, which was based on that for
  javascript, which was only thinning because it was reading everything into
  memory and the larger vocabulary lists were resulting in out of memory
  issues.

* javascript: Speed up stemwords.js.  Process input line-by-line rather than
  reading the whole file into memory, splitting, iterating, and creating an
  array with all the output, joining and writing out a single huge string.
  This also means we can stop thinning the test data for javascript, which we
  were only doing because the huge arabic test data file was causing out of
  memory errors.  Also drop the -p option, which isn't useful here and
  complicates the code.

* rust: Turn on optimisation in the makefile rather than the CI config.  This
  makes the tests run in about 1/5 of the time and there's really no reason to
  be thinning the testdata for rust.

Documentation
-------------

* CONTRIBUTING.rst: Improve documentation for adding a new stemming algorithm.

* Improve wording of Python docs.

1.6.1 (2025-03-25)

* Performed further work on Diff::LCS::Ldiff improvements (#46) and resolve
  several thread safety issues cleanly by making it a class. #129

* Restructure the project to be more consistent with the rest of the
  projects that I manage.

* Increased GitHub action security.

* Added trusted publishing for fully automated releases.


1.6.2 (2025-05-12)

* Handle upcoming changes to the cgi gem in Ruby 3.5 (#147)

* Fix issues found with htmldiff in Ruby 1.8 (which is used approximately
  never, since the code change which broke Ruby 1.8 was made 6 years
  ago). #148

* Fixed some standardrb formatting and configuration issues.

 - fix alpha_dec template variable #97 (0081380d74)
 - add unlimited recursive, but can be controled with max_depth on
   templates that are directories by default #129 (0dad75b717)
 - cache internal structure (4b9dfdd98c)
   which benefits reusability and, thus, speed in situations when you
   don't change the backend, or only change the palette.
 - add new template variables for displaying colors with rgb decimals #176

++ a lot of internal changes.. ++

 - colorspaces internal refactors and upgrades (0838839082), (feb8e3c60b), (80f59115d2), (80caaf70dc)
   * make lch work with lover contrast images (fda444c3b9)
 - backends kmeans: new internal defaults (d36d2ff180)
