 ## [Unreleased]
 
+## [0.5.0]

 ### Added
 - Error boundary catches React crashes and displays an error page instead of a white screen
 - Startup timeout (10s) on database connection — shows error page instead of infinite spinner
 - Error page with "Refresh", "Check for updates", and contact/issue links
 - Log viewer in settings page — captures console output, filterable by level, copyable, persists across refresh
+- GPL-3.0 license — project is now open source
 
 ### Changed
 - Report detail modal: sortable columns — click headers to sort by date, description, or amount (#1)
