osobhandClaude Opus 5.5 e01160299a docs: plugin filters and the filter registry
CHANGELOG (Unreleased): LZF, bitshuffle, bzip2 and Blosc read and write
in pure Rust, their features, the ChunkOptions::plugin field (breaking for
struct-literal construction), the filter registry, the named
UnsupportedFilter message, and Blosc2/ZFP still unimplemented.
README: the clawhdf5-format feature table gains lzf (default),
bitshuffle, bzip2, blosc and plugin-filters, with how to write them and
what is not implemented; no speed claims. docs/known-issues.md: the audit's
filter gap is marked fixed 2026-09-26 for LZF/bitshuffle/bzip2/Blosc,
Blosc2 and ZFP still open. CLAUDE.md: the clawhdf5-filters row no longer
says "No Blosc". clawhdf5-format's crate docs list the new features.
