What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

---

- **fixed** — Nested workspace packages in monorepos now own their own surfaces, explicit projectRoots win over guessing, and a parent's design system applies only when that root actually owns the path
- **fixed** — Design hook installs at a path that broke on update and Grok's camelCase payloads no longer read as empty scans
- **fixed** — Clean scan now clears the finding cache instead of nagging
- **fixed** — Stop hook emits the decision shape Codex expects so the design gate actually gates
- **fixed** — Dashed single-direction rules no longer read as grid backgrounds
- **fixed** — Comments are stripped before pattern matching in detector
- **fixed** — oklch now parses in the contrast checks
- **fixed** — Hex tucked inside color-mix() no longer trips gradient contrast
- **fixed** — Root-relative stylesheets are now scanned by resolving links against the scan root
- **fixed** — Parent directory escapes in stylesheet links are refused with a warning
- **fixed** — Claude subagents install correctly again
- **fixed** — Home-scoped agents refresh when they go stale
- **fixed** — Hook migration on Windows stops duplicating entries
- **fixed** — Context helper drains stdout and closes its sockets before exiting to stop Windows setup output truncating
- **fixed** — Preview server refuses symlinks that lead outside your workspace
- **fixed** — Page-controlled fields are stripped before they reach the agent
- **fixed** — Direction page no longer hangs after a re-roll
- **fixed** — Ground-color drift between the approved comp and the shipped page is caught on any palette now, not just cream
- **fixed** — Code-led fallback for ground color is now deterministic

- **Monorepos find the right DESIGN.md.** Nested workspace packages own their own surfaces, an explicit projectRoots wins over guessing, and a parent's design system applies only when that root actually owns the path.

- **The design hook works on Grok Build again.** Installs pointed project hooks at a path that broke on update, and Grok's camelCase payloads read as empty scans. Both fixed, and a clean scan now clears the finding cache instead of nagging.

- **Codex hears the block.** The Stop hook emits the decision shape Codex expects, so the design gate actually gates.

- **Fewer detector false alarms.** Dashed single-direction rules stop reading as grid backgrounds, comments are stripped before pattern matching, oklch parses in the contrast checks, and a hex tucked inside color-mix() no longer trips gradient contrast.

- **Root-relative stylesheets get scanned.** A page linking `/styles.css` used to be judged without its CSS by static detection; those links now resolve against the scan root, and `..` escapes are refused with a warning.

- **Installs repair cleanly.** Claude subagents install correctly again, home-scoped agents refresh when they go stale, and hook migration on Windows stops duplicating entries.

- **Windows setup output stops truncating.** The context helper drains stdout and closes its sockets before exiting, so directives no longer vanish mid-boot.

- **Live mode housekeeping.** The preview server refuses symlinks that lead outside your workspace, page-controlled fields are stripped before they reach the agent, and the direction page no longer hangs after a re-roll.

- **Comps keep their ground.** Ground-color drift between the approved comp and the shipped page is caught on any palette now, not just cream, and the code-led fallback is deterministic.
