 # Changelog
 
+## v0.3.1 - 2026-09
+
+### Description
+
+A maintenance release. It carries the toolchain forward, closes one interface bug that
+crashed on device, and puts the workflow files under static analysis.
+
+### Fixes
+
+- A button with an interpolated label, such as the cameras "Select all (2)" control, no
+  longer crashes: its bare text now renders inside a `Text` node
+
+### Security
+
+- Monaco's transitive DOMPurify moved to a patched release
+- CodeQL analyses the GitHub Actions workflows alongside the Python and TypeScript code
+- Dropped two dependency advisory waivers that no longer match anything in the tree
+
+### Maintenance
+
+- Jest 30, pnpm 12, AsyncStorage 3, and React Native Testing Library 14
+- Refreshed container images, the Cloudflare Terraform provider, and the lockfiles
+- Held Babel and TypeScript at the majors their toolchains still support
+- Declared the licence in package metadata and added CODEOWNERS
+
 ## v0.3.0 - 2026-09
