# Changelog



This changelog starts at 1.5.5; earlier releases are recorded by git

tags and `bench/results/*.md` session documents.



## 1.5.5 (2026-08-08)



Validated against the released **timeless-libsql v0.5.0** and re-pinned

the CI/release workflows to that tag (they previously built a pre-0.4.0

development rev, 409 commits behind). The capability preflight —

data ABI 1 + rich-v1 logs batches — passes unchanged, and the full

suite (230 tests, including crash-boundary migration resume and

cold-parity validation over 8,193 entries) is green against v0.5.0.



- **Message compression:** the migration's final `optimize` under a

  v0.5.0 extension now template-compresses rich log message columns

  (CLP-style codec 8; timeless-libsql measured 1.29–2.44× smaller

  blocks on message-dominated corpora, with a per-block fallback that

  never regresses). Consequence: once a migrated `logs.db` has been

  optimized by v0.5.0, its readers need timeless-libsql ≥ 0.5.0 —

  pre-0.5.0 extensions refuse the new blocks loudly.

- The libSQL migration candidate now traps exits so its connection and

  WAL close even when the linked migration caller dies mid-run.
