chore(changelog): release entry for 1.0.0-rc.3#97
Merged
Conversation
Consolidates the existing [Unreleased] section and the stale [1.0.0] — TBD stub into a single [1.0.0-rc.3] — 2026-05-19 release entry. Adds the parser-ecosystem and tooling items that landed via the experimental merge but weren't yet captured under Unreleased (the rer-package crate, parse_static_package_py / parse_static_packages_py PyO3 bindings, the differential safety net, the survey + bench + bisect scripts, and the production integration / engineering RFC docs). Structure follows Keep a Changelog: Added / Changed plus a Performance subsection that names the bench script behind each number and qualifies the corpus context (`/thierry/rez/pkg` on CIFS, against rez 3.3.0). The 0-mismatches differential result is highlighted as the load-bearing correctness claim. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
