OpenCode v1.2.1: SQLite Migration & PartDelta Events
OpenCode v1.2.1 ships SQLite migration and PartDelta events for SDK users. One-time data conversion on first run—plan accordingly if you have large datasets.
TL;DR
- Flat file data migrates to SQLite on first run — may take time depending on your dataset
- New PartDelta event for SDK users sends only incremental changes, not full content
- Original data preserved during migration; downgrade works if something breaks
New
- PartDelta event — SDK users now get incremental-only updates for text parts instead of full content resends, reducing bandwidth overhead
- Project sessions from any directory — view all sessions regardless of working directory context
Fixed
- Websearch tool description tweaked to prevent cache busts from date info
Breaking Changes
- SQLite migration on first run — all flat files in your data directory convert to a single SQLite database. This is one-time only but can take time with large datasets. If migration fails, delete
~/.local/share/opencode/opencode.db*files (%APPDATA%on Windows) to retry. Original data stays intact until you confirm the migration works, so downgrading is safe if needed. Open an issue with "sqlite" in the title if you hit problems.
