 # Changelog
 
-## Unreleased
+## 0.5.0 — 2026-10-04
 
 - **Brand completion:** after `brand:` in `.archify` files and Archify JSON sources, the editor suggests the 107 built-in brand IDs with their product names. Aliases and product names match too (`kafka` → `apache-kafka`, `postgres` → `postgresql`).
 - **Unknown brands are underlined on their own line.** Archify reports these without a location, so they used to appear at the top of the file.
