Added

• PR#81 resolved #68 by adding support for the WITH [%s"DocumentRef-"(idstring)":"]%s"AdditionRef-"(idstring) syntax. Thanks @weihanglo!

Changed

• PR#80 changed how Licensee::satisfies works for GNU licenses again, it now requires that the license ids match exactly. This is incredibly pedantic but means it's up to consumers if the want to have a smarter comparison, I just don't want to have to care about GNU licenses, ever.

Fixed

• PR#80 reverted a change introduced in PR#78 that would auto-fixup GNU licenses to their non-deprecated forms eg. GPL-2.0 => GPL-2.0-only. This is no longer done, resolving #79.

Changed

• PR#78 removed ParseMode::allow_lower_case_operators, newer revisions of the SPDX spec allow all lower-case operators, making the option pointless.
• PR#78 added ParseMode::allow_deprecated, which will cause an error if a deprecated license identifier is used, false in LAX and true in STRICT.
• PR#78 changed the various imprecise names for GPL licenses to be mapped to the non-deprecated -only versions.
• PR#78 Expression::canonicalize now always changes GNU licenses to be -only or -or-later as the bare identifiers are deprecated.

Added

• PR#78 added LicenseId::version to retrieve the numeric version of the license if it has one.
• PR#78 added LicenseId::base to retrieve the base name of the license.
• PR#78 added gnu_license_id which attempts to retrieve the license id for a GNU license from its base identifier. This retrieves the -only or -or-later license that matches.
• PR#78 added Licensee::parse_mode, Licensee::parse now forwards to that function with ParseMode::STRICT.
• PR#78 added Reason::GnuPlusWithSuffix and Reason::DeprecatedLicenseId as errors.

Fixed

• PR#78 fixed an issue where Licensee::satisfies would not properly allow some licenses if the version was not at the end when using a +, notably the BSD licenses have the version in the middle of the license id.
• PR#78 fixed the handling of GNU licenses in Licensee::satisfies, at least to my best understanding.
