Update changelog for 17.0.0.rc.6

[justin808]

Why

Stamps the 17.0.0.rc.6 changelog section so the release task can publish it and auto-create the GitHub release. This is the changelog step that comes before running bundle exec rake release (the release task reads the version + notes from CHANGELOG.md).

What

Ran a full /update-changelog classification sweep over the 78 merged PRs in v17.0.0.rc.5..origin/main (plus one revert commit) before stamping. Most are docs/agent-workflow/CI/test changes (no-entry); the user-visible ones were already accumulated under [Unreleased] during development.

Stamping: bundle exec rake "update_changelog[17.0.0.rc.6]" inserted the ### [17.0.0.rc.6] - 2026-06-21 header after [Unreleased], moved the accumulated entries under it, and rewrote the compare links (v17.0.0.rc.5...v17.0.0.rc.6, [unreleased] → main). Prior RC sections are preserved (RC mode does not collapse them).

Changelog edits made in this pass:

• Added one missing entry — RSC-safe generated i18n locale defaults (#4146): the only user-visible PR merged after rc.5 that was not yet in the changelog (gem runtime change in lib/react_on_rails/locales/, fixes i18n compiler generates RSC-incompatible default.js #4132).
• Co-credited #4107 alongside Fix generated demo path hints for custom Shakapacker roots #4130 on the "generated demo paths honor custom Shakapacker source roots" entry — Wrap generated demo file paths in onboarding page (Part 1 of #4062) #4107 is the demo-path-wrapping half of the same Issue Follow-up: wrap generated demo file paths and derive source hints from Shakapacker config #4062 work, already described in that entry.
• Added the missing PR link (#4096) to the RenderFunction types-only breaking-change entry, which previously linked only the issue.
• Reordered the rc.6 category sections to the standard Added → Changed → Fixed, matching rc.2/rc.4 and the changelog skill's documented order (the [Unreleased] accumulation had led with Fixed).

The 17.0.0.rc.6 section contains 14 entries (3 Added, 4 Changed, 7 Fixed).

Test plan

• bundle exec rake "update_changelog[17.0.0.rc.6]" (run with a UTF-8 locale to avoid the invalid byte sequence in US-ASCII regex bug) → header + compare links stamped.
• pnpm exec prettier --check CHANGELOG.md → clean.
• Pre-commit/pre-push hooks: trailing-newlines, Lychee markdown links (8 OK / 0 errors), Prettier, branch-lint → all pass.
• Verified [Unreleased] is now empty, version headers are newest-first, and compare links use the v prefix.

Labels

Labels: none — changelog/docs-only change; relies on the required PR gate plus the local verification above.

After merge

Run bundle exec rake release (no args — it reads 17.0.0.rc.6 from the changelog) to publish and auto-create the GitHub release.

Note: main currently shows pre-existing detect-changes failures unrelated to this changelog-only change.

Walkthrough

CHANGELOG.md is updated to add the 17.0.0.rc.6 release entry dated 2026-06-21, reorganizing its bullets into "Breaking (types only)" and "Fixed" subsections. The bottom reference links are updated so [unreleased] compares from v17.0.0.rc.6 and the new release links back to v17.0.0.rc.5.

Greptile Summary

This PR stamps the 17.0.0.rc.6 release in CHANGELOG.md by converting the [Unreleased] section into a dated version header and updating the compare links at the bottom of the file.

• Moves 14 accumulated changelog entries (3 Added, 4 Changed, 7 Fixed) from [Unreleased] into a new ### [17.0.0.rc.6] - 2026-06-21 section, reordering to the canonical Added → Changed → Fixed sequence.
• Adds one new entry (PR Fix RSC-safe locale default messages output #4146 — RSC-safe generated i18n locale defaults), co-credits PR Wrap generated demo file paths in onboarding page (Part 1 of #4062) #4107 on the demo-path entry, and adds the missing PR link for the RenderFunction breaking-change entry (Split RenderFunction: drop the legacy renderer arm (#3592) #4096).
• Updates the bottom compare links: [unreleased] now points to v17.0.0.rc.6...main, and a new [17.0.0.rc.6] link targets v17.0.0.rc.5...v17.0.0.rc.6.

Confidence Score: 5/5

Changelog-only change with no code modifications; safe to merge.

The sole changed file is CHANGELOG.md. The stamping is mechanically correct: [Unreleased] is emptied, a new dated version header is inserted, entries are reordered to the canonical Added → Changed → Fixed sequence, the entry count matches the PR description (3 + 4 + 7 = 14), and the compare links at the bottom correctly reference v17.0.0.rc.5...v17.0.0.rc.6 and v17.0.0.rc.6...main. No runtime or build artifacts are affected.

No files require special attention.

Code Review: Update changelog for 17.0.0.rc.6

Overview: This is a changelog-only PR that stamps the 17.0.0.rc.6 release section in CHANGELOG.md. The [Unreleased] block is correctly emptied, the version header and compare links are inserted, and four targeted edits were applied before stamping.

---

What the PR does

• Moves all previously accumulated [Unreleased] entries into a new ### [17.0.0.rc.6] - 2026-06-21 section
• Reorders sections to the standard Added → Changed → Fixed sequence (was Fixed-first due to accumulation order)
• Adds one new entry missed since rc.5: RSC-safe generated i18n locale defaults (#4146)
• Co-credits #4107 on the demo-paths Fixed entry
• Adds the missing #4096 PR link to the RenderFunction breaking-change entry
• Updates compare links at the bottom of the file

---

Review findings

Format / structure — LGTM

• Section order (Added → Changed → Fixed) matches rc.2 and rc.4 and the Keep a Changelog convention. ✓
• Compare link format uses the v prefix consistently (v17.0.0.rc.5...v17.0.0.rc.6), matching all prior RC links. ✓
• [unreleased] footer link now points to v17.0.0.rc.6...main — correct. ✓
• [Unreleased] section header remains as a blank placeholder for future entries — correct. ✓
• Entry count (3 Added + 4 Changed + 7 Fixed = 14) matches the PR description. ✓

Minor inconsistency — blank lines in Fixed section

All Fixed entries are separated by a blank line except the fifth and sixth:

- **Abort the in-flight SSR render…** [PR 4093]
- **[Pro]** **Bounded the RSCProvider RSC payload cache…** [PR 4097]   ← missing blank line before this

Every other consecutive Fixed entry has a blank line between them. This is cosmetic only and does not affect rendering, but it is inconsistent with the surrounding style.

Content accuracy

• The new Fix RSC-safe locale default messages output #4146 i18n entry accurately describes the compiler change (removes defineMessages/react-intl import, emits plain object, treats stale default.js as regenerable).
• Wrap generated demo file paths in onboarding page (Part 1 of #4062) #4107 + Fix generated demo path hints for custom Shakapacker roots #4130 co-credit on the demo paths entry is correct — both PRs contributed to Issue 4062.
• Split RenderFunction: drop the legacy renderer arm (#3592) #4096 addition to the RenderFunction entry fills the only missing PR link in the Changed section.
• No duplicate entries, no entries carried over from rc.5.

---

Verdict

The stamping is accurate and the changelog is in good shape for release. The only actionable item is the missing blank line between the "Abort SSR" and "Bounded RSCProvider" Fixed entries (lines 52–53 in the current file) — easy one-line fix before merge if you want strict style consistency, but safe to merge as-is given it is purely cosmetic.
