 # Breaking Changes
 
-## 0.0.238
-
-### `select`, `extend-select`, `ignore`, and `extend-ignore` have new semantics ([#2312](https://github.com/charliermarsh/ruff/pull/2312))
-
-Previously, the interplay between `select` and its related options could lead to unexpected
-behavior. For example, `ruff --select E501 --ignore ALL` and `ruff --select E501 --extend-ignore
-ALL` behaved differently. (See [#2312](https://github.com/charliermarsh/ruff/pull/2312) for more
-examples.)
-
-When Ruff determines the enabled rule set, it has to reconcile `select` and `ignore` from a variety
-of sources, including the current `pyproject.toml`, any inherited `pyproject.toml` files, and the
-CLI.
-
-The new semantics are such that Ruff uses the "highest-priority" `select` as the basis for the rule
-set, and then applies any `extend-select`, `ignore`, and `extend-ignore` adjustments. CLI options
-are given higher priority than `pyproject.toml` options, and the current `pyproject.toml` file is
-given higher priority than any inherited `pyproject.toml` files.
-
-`extend-select` and `extend-ignore` are no longer given "top priority"; instead, they merely append
-to the `select` and `ignore` lists, as in Flake8.
-
-This change is largely backwards compatible -- most users should experience no change in behavior.
-However, as an example of a breaking change, consider the following:
-
-```toml
-[tool.ruff]
-ignore = ["F401"]
-```
-
-Running `ruff --select F` would previously have enabled all `F` rules, apart from `F401`. Now, it
-will enable all `F` rules, including `F401`, as the command line's `--select` resets the resolution.
-
-### `remove-six-compat` (`UP016`) has been removed ([#2332](https://github.com/charliermarsh/ruff/pull/2332))
-
-The `remove-six-compat` rule has been removed. This rule was only useful for one-time Python 2-to-3
-upgrades.
-
-## 0.0.237
-
-### `--explain`, `--clean`, and `--generate-shell-completion` are now subcommands ([#2190](https://github.com/charliermarsh/ruff/pull/2190))
-
-`--explain`, `--clean`, and `--generate-shell-completion` are now implemented as subcommands:
-
-```console
-ruff .         # Still works! And will always work.
-ruff check .   # New! Also works.
-

-This change is largely backwards compatible -- most users should experience
-no change in behavior. However, please note the following exceptions:
-
-* Subcommands will now fail when invoked with unsupported arguments, instead
-  of silently ignoring them. For example, the following will now fail:
-
-  ```console
-  ruff --clean --respect-gitignore
-  ```
-
-  (the `clean` command doesn't support `--respect-gitignore`.)
-
-* The semantics of `ruff <arg>` have changed slightly when `<arg>` is a valid subcommand.
-  For example, prior to this release, running `ruff rule` would run `ruff` over a file or
-  directory called `rule`. Now, `ruff rule` would invoke the `rule` subcommand. This should
-  only impact projects with files or directories named `rule`, `check`, `explain`, `clean`,
-  or `generate-shell-completion`.
-
-* Scripts that invoke ruff should supply `--` before any positional arguments.
-  (The semantics of `ruff -- <arg>` have not changed.)
-
-* `--explain` previously treated `--format grouped` as a synonym for `--format text`.
-  This is no longer supported; instead, use `--format text`.

-### Project structure
-
-Ruff is structured as a monorepo with a [flat crate structure](https://matklad.github.io/2021/08/22/large-rust-workspaces.html),
-such that all crates are contained in a flat `crates` directory.
-
-The vast majority of the code, including all lint rules, lives in the `ruff` crate (located at
-`crates/ruff`). As a contributor, that's the crate that'll be most relevant to you.
-
-At time of writing, the repository includes the following crates:
-
-- `crates/ruff`: library crate containing all lint rules and the core logic for running them.
-- `crates/ruff_cli`: binary crate containing Ruff's command-line interface.
-- `crates/ruff_dev`: binary crate containing utilities used in the development of Ruff itself (e.g., `cargo dev generate-all`).
-- `crates/ruff_macros`: library crate containing macros used by Ruff.
-- `crates/ruff_python`: library crate implementing Python-specific functionality (e.g., lists of standard library modules by versionb).
-- `crates/flake8_to_ruff`: binary crate for generating Ruff configuration from Flake8 configuration.
-
 ### Example: Adding a new lint rule

+1. Create a file for your rule (e.g., `src/rules/flake8_bugbear/rules/abstract_base_class.rs`).

-4. Define the logic for triggering the violation in `crates/ruff/src/checkers/ast.rs` (for AST-based
-   checks), `crates/ruff/src/checkers/tokens.rs` (for token-based checks), `crates/ruff/src/checkers/lines.rs`
-   (for text-based checks), or `crates/ruff/src/checkers/filesystem.rs` (for filesystem-based
-   checks).

 5. Add a test fixture.
 6. Update the generated files (documentation and generated code).
