This is a feature release, which includes new features, removes previously deprecated code, and adds new deprecations. The 2.3.x branch is now the supported fix branch, the 2.2.x branch will become a tag marking the end of support for that branch. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. Test with warnings treated as errors to be able to adapt to deprecation warnings early.

attacks. :cwe:CWE-407

This release is a milestone: it fixes Black's first CVE security vulnerability. If you
run Black on untrusted input, or if you habitually put thousands of leading tab
characters in your docstrings, you are strongly encouraged to upgrade immediately to fix
CVE-2024-21503.
This release also fixes a bug in Black's AST safety check that allowed Black to make
incorrect changes to certain f-strings that are valid in Python 3.12 and higher.
Stable style
Don't move comments along with delimiters, which could cause crashes (#4248)
Strengthen AST safety check to catch more unsafe changes to strings. Previous versions
of Black would incorrectly format the contents of certain unusual f-strings containing
nested strings with the same quote type. Now, Black will crash on such strings until
support for the new f-string syntax is implemented. (#4270)
Fix a bug where line-ranges exceeding the last code line would not work as expected
(#4273)
Performance
Fix catastrophic performance on docstrings that contain large numbers of leading tab
characters. This fixes
CVE-2024-21503.
(#4278)
Documentation
Note what happens when --check is used with --quiet (#4236)
24.2.0
Stable style
Fixed a bug where comments where mistakenly removed along with redundant parentheses
(#4218)
Preview style
Move the hug_parens_with_braces_and_square_brackets feature to the unstable style
due to an outstanding crash and proposed formatting tweaks (#4198)
Fixed a bug where base expressions caused inconsistent formatting of ** in tenary
expression (#4154)
Checking for newline before adding one on docstring that is almost at the line limit
(#4185)
Remove redundant parentheses in case statement if guards (#4214).
