- - Stop a minified inlined chunk leaving a doubled `;` in its `<script>`. (by [@alexander-akait](https://github.com/alexander-akait) in [#22370](https://github.com/webpack/webpack/pull/22370))
- - Stop `mergeDistantRules` mangling rules or reordering `all`, and merge more. (by [@alexander-akait](https://github.com/alexander-akait) in [#22370](https://github.com/webpack/webpack/pull/22370))
- - Minify by parsing with webpack's own parser rather than terser's. (by [@alexander-akait](https://github.com/alexander-akait) in [#22397](https://github.com/webpack/webpack/pull/22397))
- - Read JavaScript with webpack's parser alone when minifying, refusing early errors. (by [@alexander-akait](https://github.com/alexander-akait) in [#22397](https://github.com/webpack/webpack/pull/22397))
- - Parse an `assert(...)` call after an import with no semicolon, and a regular expression after `yield` in a generator method. (by [@alexander-akait](https://github.com/alexander-akait) in [#22406](https://github.com/webpack/webpack/pull/22406))
- - Keep the private names a direct `eval` reads when mangling. (by [@aryanraj45](https://github.com/aryanraj45) in [#22412](https://github.com/webpack/webpack/pull/22412))
- - Keep a class dropped for its effects where they read a private name it declares. (by [@aryanraj45](https://github.com/aryanraj45) in [#22421](https://github.com/webpack/webpack/pull/22421))
- - Parenthesize the right side of a private `in`, a `yield`, `await`, private `in` or optional chain tagging a template, and a `let` or `async` starting a statement or loop head, where the minifier printed code that no longer parsed or read otherwise. (by [@aryanraj45](https://github.com/aryanraj45) in [#22437](https://github.com/webpack/webpack/pull/22437))
- - Keep a name a parameter list or catch parameter reads from resolving to what the function body or catch block declares, which the minifier renamed or dropped as unused. (by [@aryanraj45](https://github.com/aryanraj45) in [#22439](https://github.com/webpack/webpack/pull/22439))
- - Scope and export a CSS Modules `@value` the same way whether local or imported. (by [@alexander-akait](https://github.com/alexander-akait) in [#22443](https://github.com/webpack/webpack/pull/22443))
- - Keep CSS `border: none` and gradient fallbacks for units a target cannot read. (by [@alexander-akait](https://github.com/alexander-akait) in [#22567](https://github.com/webpack/webpack/pull/22567))
- - Keep minified CSS safe for older browsers; drop dead fallbacks and overrides. (by [@alexander-akait](https://github.com/alexander-akait) in [#22696](https://github.com/webpack/webpack/pull/22696))
- - Keep CSS rules apart from a neighbor whose selector no browser parses. (by [@alexander-akait](https://github.com/alexander-akait) in [#22634](https://github.com/webpack/webpack/pull/22634))
- - Keep an `:nth-*()` argument with a space after its sign as written. (by [@alexander-akait](https://github.com/alexander-akait) in [#22700](https://github.com/webpack/webpack/pull/22700))
- - Keep minified CSS readable by browsers the compat data does not cover. (by [@alexander-akait](https://github.com/alexander-akait) in [#22701](https://github.com/webpack/webpack/pull/22701))
- - Keep a module its chunk still needs after `compilation.rebuildModule()`. (by [@alexander-akait](https://github.com/alexander-akait) in [#22705](https://github.com/webpack/webpack/pull/22705))
- - Keep a CSS rule nested under a selector opening on a combinator when lowering. (by [@alexander-akait](https://github.com/alexander-akait) in [#22707](https://github.com/webpack/webpack/pull/22707))
- - Use module paths for webpack's built-in minimizers so parallel minification can load them directly in workers instead of serializing their function sources. (by [@xiaoxiaojx](https://github.com/xiaoxiaojx) in [#22309](https://github.com/webpack/webpack/pull/22309))
- - Keep stats from an earlier build readable after a later build no longer has one of their modules. (by [@alexander-akait](https://github.com/alexander-akait) in [#22695](https://github.com/webpack/webpack/pull/22695))
