Release Notes - v1.1.1.dev0
Release Date: 2026-05-22
Changes: v1.1.1.dev0 → fix-varchar-size
Summary
This patch release fixes a database schema issue that could cause user text fields to be silently truncated. It includes a safe migration to enlarge varchar columns and adds validation so truncation is detected earlier. The result is more reliable storage of user memories and metadata without data loss.
Highlights
- Fixed varchar size limits that could silently truncate user content
- Safe database migration included to resize affected columns
- Validation added to detect input that previously would be truncated
- Improved reliability for search and indexing that depended on full text
Breaking Changes
- Database schema migration is required: upgrade includes a migration that must be applied to existing databases before running the new code. Back up your database and run the provided migration (or your normal migration process) during deployment.
- If you maintain a custom database schema or applied manual schema patches, you might need to reconcile those changes with the new column sizes to avoid conflicts.
New Features
- Database migration that increases varchar sizes for fields used to store user memories and metadata, preventing silent truncation of long values
- Input validation that warns or blocks values that would exceed column limits before they are saved
Improvements
- More robust storage for user-generated content — longer texts are now preserved end-to-end
- Search and indexing behavior improved because stored values are no longer truncated
- Better error messages and logging when user input approaches storage limits
Bug Fixes
- Fixed bug where long strings could be silently truncated when saved to the database
- Resolved issues where truncated values caused unexpected search results or indexing errors
Technical Changes
- Refactored schema definitions to centralize varchar size configuration and reduce future regressions
- Added automated tests around maximum field lengths and migration behavior
- Included a migration file to perform the column size changes (apply via your migration toolchain)
