rspack v2.2.1

Highlights

Corrected compact-hashed IDs naming

Rspack 2.2.0 introduced compact hashed module and chunk IDs under the mistakenly named compat-hashed option and CompatHashedModuleIdsPlugin / CompatHashedChunkIdsPlugin APIs. Rspack 2.2.1 corrects these names to compact-hashed, CompactHashedModuleIdsPlugin, and CompactHashedChunkIdsPlugin.

The names introduced in 2.2.0 remain available as deprecated compatibility aliases, but we recommend upgrading to Rspack 2.2.1 and using the corrected names:

module.exports = {
  optimization: {
    moduleIds: 'compact-hashed',
    chunkIds: 'compact-hashed',
  },
};
