##### What's Changed
- fix(parser): fix lexer error while parsing parenthesized arrow expressions by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3400](https://togithub.com/oxc-project/oxc/pull/3400)
The previous version refactored some parsing code around arrow expressions, which failed to parse the following snippet correctly
```javascript
(/\./.exec())
```

### [`v0.4.0`](https://togithub.com/oxc-project/oxc/releases/tag/oxlint_v0.4.0): oxlint v0.4.0
[Compare Source](https://togithub.com/oxc-project/oxc/compare/754d9f4c98aab052cf6b2756f7af12557042708d...e5337f00b1c7b49cb09d28b860e112d4ebad3233)
##### Potential Breaking Changes
##### enforce rule severity from the cli and configuration file by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3337](https://togithub.com/oxc-project/oxc/pull/3337)
The `--deny` or `-D` flag in the CLI, and the `"error"` severity setting in the configuration file will now set linter diagnostics to be an "error" and exit the program with exit code 1.
Previously, these flags had no effect, and all linter diagnostics were reported as warnings.
This means in CI, `oxlint --deny-warnings` is no longer needed for exit code 1 if `oxlint -D correctness` is set.
To restore the previous "report as warning" behaviour, the `--warn` or `-W` flag is added to the CLI, and the `"warn"` severity in the configuration file will take into effect.
##### merge deepscan rules into oxc rules by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3327](https://togithub.com/oxc-project/oxc/pull/3327)
`deepscan` rules are now "oxc" rules, because there is no "deepscan" plugin in the eslint ecosystem and this caused some confusion.
##### Ecosystem CI
We added the [`Oxlint Ecosystem CI`](https://togithub.com/oxc-project/oxlint-ecosystem-ci/actions/workflows/ecosystem-ci.yml) to maximize ecosystem compatibility, reduce churn, and minimize break-after-release
##### New Features
- `--disable-oxc-plugin` by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3328](https://togithub.com/oxc-project/oxc/pull/3328)
- `--disable`-react/unicorn/typescript-`plugin` by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3305](https://togithub.com/oxc-project/oxc/pull/3305)
The default rule set enables some plugins by default, the following CLI arguments are added for disabling them:
- `--disable-react-plugin`
- `--disable-unicorn-plugin`
- `--disable-oxc-plugin`
- `--disable-typescript-plugin`
##### New Rules
Two notable new rules that are under experiment but worth a try:
##### No Barrel File
`oxlint --import-plugin -D no-barrel-file`
Loading a lot of modules is slow for runtimes and bundlers.
To change the threshhold:
`oxlint -c oxlintrc.json --import-plugin -D no-barrel-file`
```json
{
"rules": {
"oxc/no-barrel-file": ["error", {
"threshold": 10
}]
}
}
```

### [`v0.4.1`](https://togithub.com/oxc-project/oxc/releases/tag/oxlint_v0.4.1): oxlint v0.4.1 [Compare Source](https://togithub.com/oxc-project/oxc/compare/e5337f00b1c7b49cb09d28b860e112d4ebad3233...d971c9cd0b7da94896179ebd5a8b95b62d05a1c1) ##### What's Changed - fix(parser): fix lexer error while parsing parenthesized arrow expressions by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3400](https://togithub.com/oxc-project/oxc/pull/3400) The previous version refactored some parsing code around arrow expressions, which failed to parse the following snippet correctly ```javascript (/\./.exec()) ``` **Full Changelog**: https://github.com/oxc-project/oxc/compare/oxlint_v0.4.0...oxlint_v0.4.1 ### [`v0.4.0`](https://togithub.com/oxc-project/oxc/releases/tag/oxlint_v0.4.0): oxlint v0.4.0 [Compare Source](https://togithub.com/oxc-project/oxc/compare/754d9f4c98aab052cf6b2756f7af12557042708d...e5337f00b1c7b49cb09d28b860e112d4ebad3233) ##### Potential Breaking Changes ##### enforce rule severity from the cli and configuration file by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3337](https://togithub.com/oxc-project/oxc/pull/3337) The `--deny` or `-D` flag in the CLI, and the `"error"` severity setting in the configuration file will now set linter diagnostics to be an "error" and exit the program with exit code 1. Previously, these flags had no effect, and all linter diagnostics were reported as warnings. This means in CI, `oxlint --deny-warnings` is no longer needed for exit code 1 if `oxlint -D correctness` is set. To restore the previous "report as warning" behaviour, the `--warn` or `-W` flag is added to the CLI, and the `"warn"` severity in the configuration file will take into effect. ##### merge deepscan rules into oxc rules by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3327](https://togithub.com/oxc-project/oxc/pull/3327) `deepscan` rules are now "oxc" rules, because there is no "deepscan" plugin in the eslint ecosystem and this caused some confusion. ##### Ecosystem CI We added the [`Oxlint Ecosystem CI`](https://togithub.com/oxc-project/oxlint-ecosystem-ci/actions/workflows/ecosystem-ci.yml) to maximize ecosystem compatibility, reduce churn, and minimize break-after-release ##### New Features - `--disable-oxc-plugin` by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3328](https://togithub.com/oxc-project/oxc/pull/3328) - `--disable`-react/unicorn/typescript-`plugin` by [@Boshen](https://togithub.com/Boshen) in [https://github.com/oxc-project/oxc/pull/3305](https://togithub.com/oxc-project/oxc/pull/3305) The default rule set enables some plugins by default, the following CLI arguments are added for disabling them: - `--disable-react-plugin` - `--disable-unicorn-plugin` - `--disable-oxc-plugin` - `--disable-typescript-plugin` ##### New Rules Two notable new rules that are under experiment but worth a try: ##### No Barrel File `oxlint --import-plugin -D no-barrel-file` Loading a lot of modules is slow for runtimes and bundlers.Configuration
