Draft CHANGELOG for the pending post-v3.8.0 release. Commit hashes are
left as "TODO LATER" placeholders, to be filled in when cutting the
release.
Fix:
- Add draft CHANGELOG section for pending release
- Note observable change in behavior for malformed/corrupt input
(incl. invalid cache references)
- Note change in default byte output (keyword auto-caching, on by
default), with opt-out pointer
- Re-frame pending release as v3.9.0 (adds a feature + changes
default byte output, so no longer patch-suitable)
