# Changelog

## 0.1.0 — Unreleased

- In-memory diff/apply with structured errors, validated explicit Limits and
  separate for_diff/for_apply defaults.
- BSDIFF40 signed-magnitude integers, checked envelope boundaries, CRC-checked
  single bzip2 stream per block and exact compressed/decoded consumption.
- Internal binary suffix indexing and matching/segment selection, with cumulative
  logical generation work budgets and bounded encoder emissions.
- Windows/Linux native diff/patch/help/version CLI, bounded binary reads and
  no-overwrite file delivery; CLI apply patch cap is 128 KiB.
- Source-checkout memory/Wasm examples and fixed 31-input bidirectional reference
  CI, with explicit full/compact target scopes and source-bound result gates.
- Five-case native-release process benchmark with raw samples and honest memory
  limits. This is not a universal speed or memory guarantee.

Compatibility: bytes outside the old file contribute zero during apply, negative
seeks are allowed, and unused/trailing/concatenated compressed data is rejected.
BSDIFF40 has no old-file identity hash. Linux CLI output requires O_TMPFILE and
/proc. Complete buffers/copies and bzip2 workspaces can coexist; work counts are
not full CPU, wall-clock or process peak-memory budgets. See docs for exact scope.

Feature scope is frozen. No new formats, sync/network/GUI/tuning interfaces or
broader guarantees will be added for 0.1.0. Compatibility fixes and final audit,
validation, publication and independent registry consumption remain pending.
No release date, published package, tag or download asset is claimed here.

Release preparation: clean-source package audit, byte-checked external candidate
consumer and fresh-cache registry consumer entry point. Publication status is
recorded separately after upload; this source does not prefill release success.
