 # Breaking Changes
 
+## 0.0.226
+
+### `misplaced-comparison-constant` (`PLC2201`) was deprecated in favor of `SIM300` ([#1980](https://github.com/charliermarsh/ruff/pull/1980))
+
+These two rules contain (nearly) identical logic. To deduplicate the rule set, we've upgraded
+`SIM300` to handle a few more cases, and deprecated `PLC2201` in favor of `SIM300`.
+
+## 0.0.225
+
+### `@functools.cache` rewrites have been moved to a standalone rule (`UP033`) ([#1938](https://github.com/charliermarsh/ruff/pull/1938))
+
+Previously, `UP011` handled both `@functools.lru_cache()`-to-`@functools.lru_cache` conversions,
+_and_ `@functools.lru_cache(maxsize=None)`-to-`@functools.cache` conversions. The latter has been
+moved out to its own rule (`UP033`). As such, some `# noqa: UP011` comments may need to be updated
+to reflect the change in rule code.
+
+## 0.0.222
+
+### `--max-complexity` has been removed from the CLI ([#1877](https://github.com/charliermarsh/ruff/pull/1877))
+
+The McCabe plugin's `--max-complexity` setting has been removed from the CLI, for consistency with
+the treatment of other, similar settings.
+
+To set the maximum complexity, use the `max-complexity` property in your `pyproject.toml` file,
+like so:
+
+```toml
+[tool.ruff.mccabe]
+max-complexity = 10
+```
+
 ## 0.0.181
 
 ### Files excluded by `.gitignore` are now ignored ([#1234](https://github.com/charliermarsh/ruff/pull/1234))

 ### Example: Adding a new lint rule
 
-There are four phases to adding a new lint rule:
+At a high level, the steps involved in adding a new lint rule are as follows:
 
-1. Define the rule in `src/registry.rs`.
-2. Define the _logic_ for triggering the rule in `src/checkers/ast.rs` (for AST-based checks),
-   `src/checkers/tokens.rs` (for token-based checks), or `src/checkers/lines.rs` (for text-based checks).
-3. Add a test fixture.
-4. Update the generated files (documentation and generated code).
+1. Create a file for your rule (e.g., `src/rules/flake8_bugbear/rules/abstract_base_class.rs`).
+2. In that file, define a violation struct. You can grep for `define_violation!` to see examples.
+3. Map the violation struct to a rule code in `src/registry.rs` (e.g., `E402`).
+4. Define the logic for triggering the violation in `src/checkers/ast.rs` (for AST-based checks),
+   `src/checkers/tokens.rs` (for token-based checks), `src/checkers/lines.rs` (for text-based
+   checks), or `src/checkers/filesystem.rs` (for filesystem-based checks).
+5. Add a test fixture.
+6. Update the generated files (documentation and generated code).
 
-To define the rule, open up `src/registry.rs`. You'll need to define both a `CheckCode` and
-`CheckKind`. As an example, you can grep for `E402` and `ModuleImportNotAtTopOfFile`, and follow the
-pattern implemented therein.
+To define the violation, start by creating a dedicated file for your rule under the appropriate
+rule origin (e.g., `src/rules/flake8_bugbear/rules/abstract_base_class.rs`). That file should
+contain a struct defined via `define_violation!`, along with a function that creates the violation
+based on any required inputs. (Many of the existing examples live in `src/violations.rs`, but we're
+looking to place new rules in their own files.)
 
-To trigger the rule, you'll likely want to augment the logic in `src/checkers/ast.rs`, which defines
-the Python AST visitor, responsible for iterating over the abstract syntax tree and collecting
-lint-rule violations as it goes. If you need to inspect the AST, you can run
-`cargo +nightly dev print-ast` with a Python file. Grep for the `Check::new` invocations to
-understand how other, similar rules are implemented.

-the `CheckCode` you defined earlier (e.g., `E402.py`). This file should contain a variety of
-violations and non-violations designed to evaluate and demonstrate the behavior of your lint rule.

 Run `cargo +nightly dev generate-all` to generate the code for your new fixture. Then run Ruff
 locally with (e.g.) `cargo run resources/test/fixtures/pycodestyle/E402.py --no-cache --select E402`.
 
 Once you're satisfied with the output, codify the behavior as a snapshot test by adding a new
-`test_case` macro in the relevant `src/[plugin-name]/mod.rs` file. Then, run `cargo test`. Your
-test will fail, but you'll be prompted to follow-up with `cargo insta review`. Accept the generated
-snapshot, then commit the snapshot file alongside the rest of your changes.
