Greptile Summary

Automated Release Please PR bumping the workspace from v0.4.7 to v0.4.8. All three touched files are purely mechanical version-string updates with no logic changes.

• .release-please-manifest.json — single version field updated to "0.4.8".
• CHANGELOG.md — new release section prepended documenting all features, bug fixes, refactors, tests, and CI changes merged since v0.4.7.
• Cargo.toml — [workspace.package] version and all 37 internal crate workspace-dependency pins (each tagged # x-release-please-version) bumped to 0.4.8; arcbox-hv intentionally remains at 0.3.20 per the comment describing its independent release cadence.

Confidence Score: 5/5

This is a fully automated release bump with no logic changes; safe to merge.

All three files contain only mechanical version-string substitutions generated by Release Please. The workspace version, all 37 internal crate pins, the manifest, and the changelog are consistently updated to 0.4.8. The one deliberate exception — arcbox-hv at 0.3.20 — is explicitly documented in the file. There is nothing here that could introduce a regression.

No files require special attention.

Important Files Changed

Filename	Overview
.release-please-manifest.json	Version bumped from 0.4.7 to 0.4.8 — single-field change, correct.
CHANGELOG.md	New 0.4.8 changelog entry prepended with all features, bug fixes, refactors, tests, and CI changes from the release.
Cargo.toml	Workspace version and all 37 internal crate pins bumped uniformly from 0.4.7 to 0.4.8; arcbox-hv intentionally left at 0.3.20 per its separate cadence comment.

✅ No new issues found.

Reviewed changes — release-please automation PR bumping the workspace to 0.4.8.

• Version bump 0.4.7 → 0.4.8 — applied to [workspace.package] and every internal path-dep pin (# x-release-please-version) in Cargo.toml, plus the matching entries in Cargo.lock.
• Manifest update — .release-please-manifest.json . set to 0.4.8.
• CHANGELOG — prepends the 0.4.8 section citing the single bug fix #305 (devenv: pin apple-sdk_26).
• Independent-cadence deps untouched — arcbox-hv (0.3.20) and arcbox-boot (0.5.1) correctly left unchanged per their documented manual cadence.

All version bumps are consistent and the changelog matches the one commit in this release. Mechanical, generated content — mergeable as-is.
