• Add the strictness option ("strict" | "balanced" | "tolerant", default "balanced") and maxAppendedDataSize option to ZipReader, controlling how appended data, prepended stubs, and ambiguous end-of-central-directory records are handled. checkAmbiguity: true is now an alias for "strict".
• Add createOPFSTempStream() and the createTempStream writer option to spill large buffered entries to the OPFS instead of memory, with an optional dispose() hook released on every exit path.
• Add FS#exportFileSystemHandle() and ZipDirectoryEntry#exportFileSystemHandle() to write an entry tree out to a FileSystemDirectoryHandle.

• Select the last end-anchored record that points to a central directory instead of the first signature scanned from the end; refuse genuine comment-cloak polyglots with ERR_AMBIGUOUS_ARCHIVE.
• Rank record reachability so empty or saturated bytes at the end of a comment can no longer forge a second record; genuine empty and zip64 archives still open.
• Prefer the reconciled central-directory offset over a stale one, so an identical-layout append remnant exposes the appended directory rather than the previous one.
• Apply the reachability check to the fallback scan, so a stray signature in appended data no longer hijacks recovery under tolerant. Security
• Bound the reachability probes to prevent a comment stuffed with unreachable records from amplifying into thousands of (potentially remote) reads on random-access readers such as HttpRangeReader.

• Speed up CRC-32 with a slice-by-8 implementation and by harvesting the CRC from the gzip trailer on the native CompressionStream.

Building with output.module is now much faster. A lodash-es production build went from 503.8 ms to 161.6 ms (-67.9%).

module.parser.javascript.importMeta now accepts an object so each known import.meta property can be configured independently, on top of the existing true / false / 'preserve-unknown' values. Properties set to false are preserved for runtime evaluation, omitted properties keep their default behavior, and unknown properties are preserved. Both webpack-compatible keys (dirname, filename, main, url, webpack, webpackContext) and Rspack-specific keys (rspackHash, rspackPublicPath, glob, ...) are supported.

export default {
  module: {
    parser: {
      javascript: {
        importMeta: {
          // keep `import.meta.url` for runtime evaluation
          url: false,
          // keep the compile-time replacement of `import.meta.webpack`
          webpack: true,
        },
      },
    },
  },
};

module.parser.javascript.worker now accepts an object form with alias and url, alongside the existing boolean and string[] forms. With url: 'new-url-relative' and output.module enabled, Rspack emits a static new URL() expression for new Worker(new URL(..., import.meta.url)) instead of runtime code, honoring output.publicPath and output.workerPublicPath.

export default {
  output: {
    module: true,
    chunkFilename: '[name].bundle.js',
  },
  module: {
    parser: {
      javascript: {
        worker: {
          url: 'new-url-relative',
        },
      },
    },
  },
};

new Worker(new URL('./worker.js', import.meta.url));

// would become 👇
new Worker(new URL('./worker.bundle.js', import.meta.url));
