Hi, I am the SymPy bot (v167). I'm here to help you write a release notes entry. Please read the guide on how to write release notes.

Your release notes are in good order.

Here is what the release notes will look like:

• parsing
  • Latex parser treats \frac and \binom as atomic (needn't wrap with braces on exponent), and supports \dfrac, \tfrac (#23475 by @eagleoflqj)

This will be added to https://github.com/sympy/sympy/wiki/Release-Notes-for-1.11.

<!-- Your title above should be a short description of what
was changed. Do not include the issue number in the title. -->

#### References to other Issues or PRs
<!-- If this pull request fixes an issue, write "Fixes #NNNN" in that exact
format, e.g. "Fixes #1234" (see
https://tinyurl.com/auto-closing for more information). Also, please
write a comment on that issue linking back to this pull request once it is
open. -->


#### Brief description of what is fixed or changed
Previously:
```py
>>> from sympy.parsing.latex import parse_latex
>>> parse_latex(R'x^\frac{1}{2}')

#### Release Notes

<!-- Write the release notes for this release below between the BEGIN and END
statements. The basic format is a bulleted list with the name of the subpackage
and the release note for this PR. For example:

* solvers
  * Added a new solver for logarithmic equations.

* functions
  * Fixed a bug with log of integers.

or if no release note(s) should be included use:

NO ENTRY

See https://github.com/sympy/sympy/wiki/Writing-Release-Notes for more
information on how to write release notes. The bot will check your release
notes automatically to see if they are formatted correctly. -->

<!-- BEGIN RELEASE NOTES -->
* parsing
  * Latex parser treats \frac and \binom as atomic (needn't wrap with braces on exponent), and supports \dfrac, \tfrac
<!-- END RELEASE NOTES -->

Update

The release notes on the wiki have been updated.

Benchmark results from GitHub Actions

Lower numbers are good, higher numbers are bad. A ratio less than 1
means a speed up and greater than 1 means a slowdown. Green lines
beginning with + are slowdowns (the PR is slower then master or
master is slower than the previous release). Red lines beginning
with - are speedups.

Looks good!

Checking the diff (without knowing anything about it really): shouldn't e.g. binom be dealt with similarly? x^\binom{N}{k} etc. Probably most of those that are now comp should be atom to handle ^ properly?

(Changing multiple of these can very well be worth a change log entry, even just with this single one since it is a clear deficiency that has been improved.)

I tested with MathJax and KaTex and the result is

binom should be added but others shouldn't.

If you can add support for \dfrac as well, that would be great (and rather straightforward).

Great!

Seems to be a merge conflict now. I was about to merge otherwise. Feel free to self-merge when the conflict is resolved.

Now it merged...
