rfc-app/CHANGELOG.md

Changelog

The binding policy for what each kind of version bump means and what the changelog has to carry is in SPEC.md §20. The practical recipe downstream deployments follow when reading this file is in docs/DEPLOYMENTS.md.

The canonical version is the VERSION file at the repo root; frontend/package.json#version mirrors it. Deployments pin to a specific framework version in their own .rfc-app-version file (per §20.5).

While the framework is pre-1.0, minor-version bumps may introduce breaking changes; the entry below each such bump documents the upgrade steps a deployment must apply.

Upgrade-steps blocks use the RFC 2119 / RFC 8174 normative- language convention per SPEC.md §20.4. MUST / SHALL steps are required; SHOULD steps are recommended (the framework's default and tested path); MAY steps are optional. Upgrades that skip versions are the composition of each intervening adjacent release's steps in order — no A-to-B path is pre-computed beyond that.

0.2.2 — 2026-05-26

Patch — no operator action required. Rebuild the frontend and restart per the routine deploy steps; no .env changes, no schema changes, no behavior changes a deployment would notice in steady state beyond the fix below.

Fixed

• Mermaid blocks rendered as raw code on /philosophy. frontend/src/components/Philosophy.jsx parsed PHILOSOPHY.md with the bare marked import and dangerouslySetInnerHTML, so ```mermaid fences fell through as <pre> blocks rather than rendered diagrams. Swapped to MarkdownPreview, which already carries the lazy mermaid loader + SVG render path used by the RFC body view, so the philosophy surface now renders mermaid the same way RFC bodies do. Pre-existing gap, surfaced when a deployment authored a mermaid block in its PHILOSOPHY_PATH override.

0.2.1 — 2026-05-26

Patch — no operator action required. Rebuild the frontend and restart per the routine deploy steps; no .env changes, no schema changes, no behavior changes a deployment would notice in steady state.

Fixed

• PR view blank page (React #310). frontend/src/components/PRView.jsx declared its threadsByKind useMemo after the early-return guard for the loading state (if (!pr) return …). On first mount pr was null so the early return fired and 14 hooks were called; on the second render pr was populated and execution reached the useMemo, calling 15 hooks — violating the Rules of Hooks and unmounting the page subtree (blank screen). The useMemo is now declared above the early returns with optional-chaining on pr, keeping the hook count stable between the loading and loaded renders. Pre-existing bug in the post-Contribute-rewrite PR view; surfaced in production by 0.2.0's graduation merge race fix enabling the workflow that opens this code path.

0.2.0 — 2026-05-26

Breaking config change. The frontend now requires VITE_APP_NAME to be set at build time. npm run build fails with a clear message if it is missing. There is no default; every deployment names itself.

Upgrade steps (from 0.1.0)

1. The deployment MUST create a frontend/.env file before building. See frontend/.env.example for the contract.
2. The deployment MUST set VITE_APP_NAME in frontend/.env to the user-visible name it wants to ship — the string used as the browser tab title, the header brand, and the landing H1. The build will fail loudly if this is unset or blank.
3. The deployment MUST rebuild the frontend (npm install && npm run build) and redeploy the resulting bundle. The previous bundle does not read VITE_APP_NAME.
4. The deployment SHOULD verify the name appears correctly in the browser tab and the header after redeploy before bumping its .rfc-app-version pin to 0.2.0.
5. The deployment MAY, in the same upgrade, take the opportunity to retire any local overrides it was using to brand the pre-0.2.0 hardcoded strings — those overrides are now obsolete.
6. The deployment MUST NOT continue to expect graduation step 4 to fail on Gitea's "Please try again later" race; that path is now handled by wait_for_mergeable + bounded retry. Any local workaround retrying graduation at the deployment level is now redundant and SHOULD be removed.

Fixed

• Graduation merge race. §13.3 step 4 (merge_pr) used to call Gitea's merge endpoint the instant step 3 returned, which races Gitea's background mergeability computation and produces the 405 "Please try again later" response. Step 4 now waits for the mergeable field to become non-null (bounded by a 30s timeout) and retries the merge call up to three times on the transient response. See backend/app/gitea.py#wait_for_mergeable and backend/app/bot.py#_merge_with_retry.

Changed

• frontend/src/App.jsx header brand reads VITE_APP_NAME instead of a hardcoded string.
• frontend/src/components/Landing.jsx H1 reads VITE_APP_NAME instead of a hardcoded string. The pitch / deck / attribution copy in this file is still deployment-specific and tracked as a follow-up for extraction into deployment config.
• frontend/index.html <title> is rewritten at build time via Vite's HTML transform.

Added

• frontend/.env.example documenting the new required variable.
• Top-level VERSION file and this CHANGELOG.md as the canonical release log.
• SPEC.md §20 (versioning and downstream deployments) as the binding policy for the framework/deployment relationship.
• docs/DEPLOYMENTS.md as the practical guide for building on rfc-app and upgrading existing deployments to new versions.
• CLAUDE.md at the repo root capturing the separation-of-concerns rule for working sessions.

0.1.0 — v1 build

Initial release. See docs/DEV.md for the slicing plan and build history.
