v0.8.0

0.8.0 (2026-05-17)

⚠ BREAKING CHANGES

• The default source parser is now oxc-parser + magic-string (was Babel). No action needed for most projects — produced class names and source maps are byte-identical to Babel output.

  Two operator-visible behavior changes:

  1. Surgical source preservation. Whitespace, parentheses, and JSX destructuring that Babel's code generator would have stripped are now preserved verbatim. First-build diffs after upgrade may show original formatting returning. This is intentional — see Phase D rationale in the project roadmap.
  2. Fallback engaged on unexpected oxc failures. If oxc throws on a file (parser error, unsupported pattern), the unplugin logs [csszyx] oxc parser fell back to Babel for ... and re-runs through Babel. No build break — worth grepping CI logs after upgrade to surface coverage gaps.

  Opting out:

  • Per project: set build.parser: 'babel' in your csszyx config.
  • Per build: set CSSZYX_PARSER=babel in the build environment.

  Both paths route prescan, transform, and HMR discovery through Babel exactly as before this release. Babel removal is not in v0.8.0 scope — @babel/* packages remain shipped for the fallback path.
