  • wiki: v1.6.12-pre - levels renumbered, fast tier, level guard, byte-delta plane lanes, LZMA-family comparison Getting Started: level table with the exact v1.6.12-pre Silesia sizes of all 15 rows and the new CLI/API numbering. Seq Stream Format: the delta bit of the plane lane mode byte. Architecture, Decoder Internals, Development: the guard, delta lanes, the XDIFF_EXT gate mode, the noise rule. Benchmarks: v1.6.12-pre against v1.6.11-pre and against xz, lzma, fast-lzma2, uf-lzma2, zpaq and RAR. Home and Roadmap: state and next candidates.

  • Benchmarks/Home/Roadmap: compare with the whole zstd ladder; measured causes of the single-thread gap The Silesia table only had zstd -1, -5 and -19. A complementary run adds the levels in between; on one thread zstd's ladder is ahead of lz6 over most of the range. Roadmap now records the measured causes (instructions per sequence, stack traffic in the decode loop, LLC misses and kernel time in the encoder). Also fixes the lizard line in Home and the ooffice "loss" in Roadmap, which the x86 filter turned into a win in v1.6.9-pre. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
