-
-### `.ipynb_checkpoints`, `.pyenv`, `.pytest_cache`, and `.vscode` are now excluded by default ([#5513](https://github.com/astral-sh/ruff/pull/5513))
-
-Ruff maintains a list of default exclusions, which now consists of the following patterns:
-
-- `.bzr`
-- `.direnv`
-- `.eggs`
-- `.git`
-- `.git-rewrite`
-- `.hg`
-- `.ipynb_checkpoints`
-- `.mypy_cache`
-- `.nox`
-- `.pants.d`
-- `.pyenv`
-- `.pytest_cache`
-- `.pytype`
-- `.ruff_cache`
-- `.svn`
-- `.tox`
-- `.venv`
-- `.vscode`
-- `__pypackages__`
-- `_build`
-- `buck-out`
-- `build`
-- `dist`
-- `node_modules`
-- `venv`
-
-Previously, the `.ipynb_checkpoints`, `.pyenv`, `.pytest_cache`, and `.vscode` directories were not
-excluded by default. This change brings Ruff's default exclusions in line with other tools like
-Black.

-## 0.0.276
-
-### The `keep-runtime-typing` setting has been reinstated ([#5470](https://github.com/astral-sh/ruff/pull/5470))
-
-The `keep-runtime-typing` setting has been reinstated with revised semantics. This setting was
-removed in [#4427](https://github.com/astral-sh/ruff/pull/4427), as it was equivalent to ignoring
-the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism.
-
-Taking `UP006` (rewrite `List[int]` to `list[int]`) as an example, the setting now behaves as
-follows:
-
-- On Python 3.7 and Python 3.8, setting `keep-runtime-typing = true` will cause Ruff to ignore
-    `UP006` violations, even if `from __future__ import annotations` is present in the file.
-    While such annotations are valid in Python 3.7 and Python 3.8 when combined with
-    `from __future__ import annotations`, they aren't supported by libraries like Pydantic and
-    FastAPI, which rely on runtime type checking.
-- On Python 3.9 and above, the setting has no effect, as `list[int]` is a valid type annotation,
-    and libraries like Pydantic and FastAPI support it without issue.
-
-In short: `keep-runtime-typing` can be used to ensure that Ruff doesn't introduce type annotations
-that are not supported at runtime by the current Python version, which are unsupported by libraries
-like Pydantic and FastAPI.
-
-Note that this is not a breaking change, but is included here to complement the previous removal
-of `keep-runtime-typing`.

-### Microbenchmarks
-
-The `ruff_benchmark` crate benchmarks the linter and the formatter on individual files.
-
-You can run the benchmarks with
-
-```shell
-cargo benchmark
-```
-
-#### Benchmark-driven Development
-
-Ruff uses [Criterion.rs](https://bheisler.github.io/criterion.rs/book/) for benchmarks. You can use
-`--save-baseline=<name>` to store an initial baseline benchmark (e.g. on `main`) and then use
-`--benchmark=<name>` to compare against that benchmark. Criterion will print a message telling you
-if the benchmark improved/regressed compared to that baseline.
-
-```shell
-# Run once on your "baseline" code
-cargo benchmark --save-baseline=main
-
-# Then iterate with
-cargo benchmark --baseline=main
-```
-
-#### PR Summary
-
-You can use `--save-baseline` and `critcmp` to get a pretty comparison between two recordings.
-This is useful to illustrate the improvements of a PR.
-
-```shell
-# On main
-cargo benchmark --save-baseline=main
-
-# After applying your changes
-cargo benchmark --save-baseline=pr
-
-critcmp main pr
-```
-
-You must install [`critcmp`](https://github.com/BurntSushi/critcmp) for the comparison.
-
-```bash
-cargo install critcmp
-```
-
-#### Tips
-
-- Use `cargo benchmark <filter>` to only run specific benchmarks. For example: `cargo benchmark linter/pydantic`
-    to only run the pydantic tests.
-- Use `cargo benchmark --quiet` for a more cleaned up output (without statistical relevance)
-- Use `cargo benchmark --quick` to get faster results (more prone to noise)
-
-### Profiling Projects
-
-You can either use the microbenchmarks from above or a project directory for benchmarking. There
-are a lot of profiling tools out there,
-[The Rust Performance Book](https://nnethercote.github.io/perf-book/profiling.html) lists some
-examples.
-
-#### Linux
-
-Install `perf` and build `ruff_benchmark` with the `release-debug` profile and then run it with perf
-
-```shell
-cargo bench -p ruff_benchmark --no-run --profile=release-debug && perf record --call-graph dwarf -F 9999 cargo bench -p ruff_benchmark --profile=release-debug -- --profile-time=1
-```
-
-You can also use the `ruff_dev` launcher to run `ruff check` multiple times on a repository to
-gather enough samples for a good flamegraph (change the 999, the sample rate, and the 30, the number
-of checks, to your liking)
-
-```shell
-cargo build --bin ruff_dev --profile=release-debug
-perf record -g -F 999 target/release-debug/ruff_dev repeat --repeat 30 --exit-zero --no-cache path/to/cpython > /dev/null
-```
-
-Then convert the recorded profile
-
-```shell
-perf script -F +pid > /tmp/test.perf
-```
-
-You can now view the converted file with [firefox profiler](https://profiler.firefox.com/), with a
-more in-depth guide [here](https://profiler.firefox.com/docs/#/./guide-perf-profiling)
-
-An alternative is to convert the perf data to `flamegraph.svg` using
-[flamegraph](https://github.com/flamegraph-rs/flamegraph) (`cargo install flamegraph`):
-
-```shell
-flamegraph --perfdata perf.data
-```
-
-#### Mac
-
-Install [`cargo-instruments`](https://crates.io/crates/cargo-instruments):
-
-```shell
-cargo install cargo-instruments
-```
-
-Then run the profiler with
-
-```shell
-cargo instruments -t time --bench linter --profile release-debug -p ruff_benchmark -- --profile-time=1
-```
-
-- `-t`: Specifies what to profile. Useful options are `time` to profile the wall time and `alloc`
-    for profiling the allocations.
-- You may want to pass an additional filter to run a single test file
-
-Otherwise, follow the instructions from the linux section.

-## Subsystems
-
-### Compilation Pipeline
-
-If we view Ruff as a compiler, in which the inputs are paths to Python files and the outputs are
-diagnostics, then our current compilation pipeline proceeds as follows:
-
-1. **File discovery**: Given paths like `foo/`, locate all Python files in any specified subdirectories, taking into account our hierarchical settings system and any `exclude` options.
-
-1. **Package resolution**: Determine the “package root” for every file by traversing over its parent directories and looking for `__init__.py` files.
-
-1. **Cache initialization**: For every “package root”, initialize an empty cache.
-
-1. **Analysis**: For every file, in parallel:
-
-    1. **Cache read**: If the file is cached (i.e., its modification timestamp hasn't changed since it was last analyzed), short-circuit, and return the cached diagnostics.
-
-    1. **Tokenization**: Run the lexer over the file to generate a token stream.
-
-    1. **Indexing**: Extract metadata from the token stream, such as: comment ranges, `# noqa` locations, `# isort: off` locations, “doc lines”, etc.
-
-    1. **Token-based rule evaluation**: Run any lint rules that are based on the contents of the token stream (e.g., commented-out code).
-
-    1. **Filesystem-based rule evaluation**: Run any lint rules that are based on the contents of the filesystem (e.g., lack of `__init__.py` file in a package).
-
-    1. **Logical line-based rule evaluation**: Run any lint rules that are based on logical lines (e.g., stylistic rules).
-
-    1. **Parsing**: Run the parser over the token stream to produce an AST. (This consumes the token stream, so anything that relies on the token stream needs to happen before parsing.)
-
-    1. **AST-based rule evaluation**: Run any lint rules that are based on the AST. This includes the vast majority of lint rules. As part of this step, we also build the semantic model for the current file as we traverse over the AST. Some lint rules are evaluated eagerly, as we iterate over the AST, while others are evaluated in a deferred manner (e.g., unused imports, since we can’t determine whether an import is unused until we’ve finished analyzing the entire file), after we’ve finished the initial traversal.
-
-    1. **Import-based rule evaluation**: Run any lint rules that are based on the module’s imports (e.g., import sorting). These could, in theory, be included in the AST-based rule evaluation phase — they’re just separated for simplicity.
-
-    1. **Physical line-based rule evaluation**: Run any lint rules that are based on physical lines (e.g., line-length).
-
-    1. **Suppression enforcement**: Remove any violations that are suppressed via `# noqa` directives or `per-file-ignores`.
-
-    1. **Cache write**: Write the generated diagnostics to the package cache using the file as a key.
-
-1. **Reporting**: Print diagnostics in the specified format (text, JSON, etc.), to the specified output channel (stdout, a file, etc.).
