Updates the requirements on zrip to permit the latest version.

Changelog

Sourced from zrip's changelog.

[0.8.1]

Changed

  • Reused Huffman decode tables and MaybeUninit FSE sequence table storage to remove per-block decode allocations.
  • Specialized decoder no-history execution and sequence table reads to reduce decode hot-loop work.
  • Specialized DFast MLS4, Fast L1 hash-log, and rare Fast MLS7 encode hot paths.
  • Preserved copied MaybeUninit sequence entries for the default path while borrowing sequence table entries in paranoid builds, recovering paranoid decode throughput.
  • Refreshed x86_64 benchmark charts after rebenchmarking zrip and zrip paranoid with performance governor and turbo off.
  • JSR package @paddor/zrip bumped to 0.5.1 for the current Rust codec.

[0.8.0]

Added

  • Level -8 (zrip-only): same parameters as old L-7 but with force_raw_literals, extending the level range from [-7, 4] to [-8, 4]. Old L-7 now gets Huffman-compressed literals while L-8 trades ratio for maximum encode throughput.
  • 3-tier dictionary setup in CompressContext adapts hash table initialization to input size: micro inputs use a linear-scan attached match finder with raw literals, small inputs add Huffman from dict tables, large inputs copy the full hash snapshot.
  • Decode-side dictionary FSE/Huffman caching: pre-promotes dict tables at construction time so each frame clones promoted tables instead of rebuilding from raw dictionary entries.

Changed

  • L2 hash_log raised from 16 (256 KB) to 17 (512 KB) for better ratio.
  • huf_worth_trying minimum gain threshold raised from n/256 (~0.4%) to n/32 (~3%) to skip Huffman table builds on marginally compressible blocks.
  • Per-level raw literals size ramp skips Huffman for tiny blocks.
  • Decode doctests changed to no_run so Miri does not attempt fearless_simd::dispatch! AVX2 paths it cannot emulate.

[0.7.3]

Fixed

  • Three UB vulnerabilities found by miri:
    • ReverseBitReader::refill_fast could underflow ptr and read out of bounds on short streams. Now returns early instead of relying on debug_assert!.
