## Unreleased
-### _Black_
+### Highlights
+
+<!-- Include any especially major or disruptive changes here -->
+
+### Style
+
+<!-- Changes that affect Black's stable style -->
+
+- Fix an infinite loop when using `# fmt: on/off` in the middle of an expression or code
+ block (#3158)
+- Fix incorrect handling of `# fmt: skip` on colon `:` lines. (#3148)
+- Comments are no longer deleted when a line had spaces removed around power operators
+ (#2874)
+
+### Preview style
+
+<!-- Changes that affect Black's preview style -->
+
+- Single-character closing docstring quotes are no longer moved to their own line as
+ this is invalid. This was a bug introduced in version 22.6.0. (#3166)
+- `--skip-string-normalization` / `-S` now prevents docstring prefixes from being
+ normalized as expected (#3168)
+
+### _Blackd_
+
+<!-- Changes to blackd -->
+
+- `blackd` now supports preview style via `X-Preview` header (#3217)
+
+### Configuration
+
+<!-- Changes to how Black can be configured -->
+
+- Black now uses the presence of debug f-strings to detect target version. (#3215)
+
+### Documentation
+
+<!-- Major changes to documentation and policies. Small docs changes
+ don't need a changelog entry. -->
+
+- Reword the stability policy to say that we may, in rare cases, make changes that
+ affect code that was not previously formatted by _Black_ (#3155)
+- Recommend using BlackConnect in IntelliJ IDEs (#3150)
+
+### Integrations
+
+<!-- For example, Docker, GitHub Actions, pre-commit, editors -->
+
+- Vim plugin: prefix messages with `Black: ` so it's clear they come from Black (#3194)
+- Docker: changed to a /opt/venv installation + added to PATH to be available to
+ non-root users (#3202)
+
+### Output
+
+<!-- Changes to Black's terminal output and error messages -->
+
+- Change from deprecated `asyncio.get_event_loop()` to create our event loop which
+ removes DeprecationWarning (#3164)
+- Remove logging from internal `blib2to3` library since it regularily emits error logs
+ about failed caching that can and should be ignored (#3193)
+
+### Packaging
+
+<!-- Changes to how Black is packaged, such as dependency requirements -->
+
+### Parser
+
+<!-- Changes to the parser or to version autodetection -->
+
+- Type comments are now included in the AST equivalence check consistently so accidental
+ deletion raises an error. Though type comments can't be tracked when running on PyPy
+ 3.7 due to standard library limitations. (#2874)
+
+### Performance
+
+<!-- Changes that improve Black's performance. -->
+

+
