 # Changelog
 
+## 0.8.0
+
+Check out the [blog post](https://astral.sh/blog/ruff-v0.8.0) for a migration guide and overview of the changes!
+
+### Breaking changes
+
+See also, the "Remapped rules" section which may result in disabled rules.
+
+- **Default to Python 3.9**
+
+    Ruff now defaults to Python 3.9 instead of 3.8 if no explicit Python version is configured using [`ruff.target-version`](https://docs.astral.sh/ruff/settings/#target-version) or [`project.requires-python`](https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#python-requires) ([#13896](https://github.com/astral-sh/ruff/pull/13896))
+
+- **Use XDG (i.e. `~/.local/bin`) instead of the Cargo home directory in the standalone installer**
+
+    Previously, Ruff's installer used `$CARGO_HOME` or `~/.cargo/bin` for its target install directory. Now, Ruff will be installed into `$XDG_BIN_HOME`, `$XDG_DATA_HOME/../bin`, or `~/.local/bin` (in that order).
+
+    This change is only relevant to users of the standalone Ruff installer (using the shell or PowerShell script). If you installed Ruff using `uv` or `pip`, you should be unaffected.
+
+- **Updated Unicode standard**
+
+    Ruff now uses a more recent version of the Unicode standard. In very rare cases, this can lead to formatting changes or new [`E501`](https://docs.astral.sh/ruff/rules/line-too-long/) violations if the computed line width differs.
+
+### Removed Rules
+
+The following deprecated rules have been removed:
+
+- [`missing-type-self`](https://docs.astral.sh/ruff/rules/missing-type-self/) (`ANN101`)
+- [`missing-type-cls`](https://docs.astral.sh/ruff/rules/missing-type-cls/) (`ANN102`)
+- [`pytest-incorrect-fixture-name-underscore`](https://docs.astral.sh/ruff/rules/pytest-incorrect-fixture-name-underscore/) (`E999`)
+- [`pytest-missing-fixture-name-underscore`](https://docs.astral.sh/ruff/rules/pytest-missing-fixture-name-underscore/) (`PT004`)
+- [`pytest-incorrect-fixture-name-underscore`](https://docs.astral.sh/ruff/rules/pytest-incorrect-fixture-name-underscore/) (`PT005`)
+- [`unpacked-list-comprehension`](https://docs.astral.sh/ruff/rules/unpacked-list-comprehension/) (`UP027`)
+
+### Remapped rules
+
+The following rules have been remapped to new rule codes:
+
+- [`flake8-type-checking`](https://docs.astral.sh/ruff/rules/#flake8-type-checking-tch): `TCH` to `TC`
+
+### Stabilization
+
+The following rules have been stabilized and are no longer in preview:
+
+- [`builtin-import-shadowing`](https://docs.astral.sh/ruff/rules/builtin-import-shadowing/) (`A004`)
+- [`mutable-contextvar-default`](https://docs.astral.sh/ruff/rules/mutable-contextvar-default/) (`B039`)
+- [`fast-api-redundant-response-model`](https://docs.astral.sh/ruff/rules/fast-api-redundant-response-model/) (`FAST001`)
+- [`fast-api-non-annotated-dependency`](https://docs.astral.sh/ruff/rules/fast-api-non-annotated-dependency/) (`FAST002`)
+- [`dict-index-missing-items`](https://docs.astral.sh/ruff/rules/dict-index-missing-items/) (`PLC0206`)
+- [`pep484-style-positional-only-argument`](https://docs.astral.sh/ruff/rules/pep484-style-positional-only-argument/) (`PYI063`)
+- [`redundant-final-literal`](https://docs.astral.sh/ruff/rules/redundant-final-literal/) (`PYI064`)
+- [`bad-version-info-order`](https://docs.astral.sh/ruff/rules/bad-version-info-order/) (`PYI066`)
+- [`parenthesize-chained-operators`](https://docs.astral.sh/ruff/rules/parenthesize-chained-operators/) (`RUF021`)
+- [`unsorted-dunder-all`](https://docs.astral.sh/ruff/rules/unsorted-dunder-all/) (`RUF022`)
+- [`unsorted-dunder-slots`](https://docs.astral.sh/ruff/rules/unsorted-dunder-slots/) (`RUF023`)
+- [`assert-with-print-message`](https://docs.astral.sh/ruff/rules/assert-with-print-message/) (`RUF030`)
+- [`unnecessary-default-type-args`](https://docs.astral.sh/ruff/rules/unnecessary-default-type-args/) (`UP043`)
+
+The following behaviors have been stabilized:
+
+- [`ambiguous-variable-name`](https://docs.astral.sh/ruff/rules/ambiguous-variable-name/) (`E741`): Violations in stub files are now ignored. Stub authors typically don't control variable names.
+- [`invalid-pyproject-toml`](https://docs.astral.sh/ruff/rules/invalid-pyproject-toml/) (`RUF200`): Updated to reflect the provisionally accepted [PEP 639](https://peps.python.org/pep-0639/).
+- [`printf-string-formatting`](https://docs.astral.sh/ruff/rules/printf-string-formatting/) (`UP031`): Report all `printf`-like usages even if no autofix is available
+
+The following fixes have been stabilized:
+
+- [`zip-instead-of-pairwise`](https://docs.astral.sh/ruff/rules/zip-instead-of-pairwise/) (`RUF007`)
