Major Changes

  • f34e80d: Remove the unused class name compression feature (classNameCompressionMap).

This removes the classNameCompressionMap / classNameCompressionMapFilePath options across the babel plugin, CSS transform, and all bundler integrations (Parcel, webpack, Vite), along with the ac runtime (and clearAcCache) from @compiled/react/runtime and the generateCompressionMap export from @compiled/css. Compiled components now always use the ax runtime for class name merging. The feature was unused in practice and its removal simplifies the codebase and reduces runtime bundle size.

Minor Changes

  • bab22a2: Update the ax() runtime to extract the atomic group key using length-based slicing (className.length - 4) instead of a hardcoded offset.

This makes ax() forward-compatible with longer atomic class names: it now correctly deduplicates both the current 9-char format (_ + 4-char group + 4-char value) and the upcoming 11-char format (_ + 6-char group + 4-char value). Because the two formats produce group keys of different lengths, they are structurally disjoint and never falsely deduplicate each other — so old and new class names can safely coexist on the same element during a migration. Behaviour for existing 9-char class names is unchanged.
