v1.2.3: Database Stability Enhancement
Release Date: February 15, 2026
One-Sentence Summary
This update improves database stability and reliability, and fixes some model variant identification issues.
New Feature: Database Checkpoints
What was updated?
Added WAL (Write-Ahead Logging) checkpoint mechanism for the SQLite database.
What is a WAL checkpoint?
Simply put, it periodically writes temporary data to the main file to prevent data loss.
Imagine you're writing an article:
- Without checkpoint: All content is cached, computer suddenly shuts down → content lost
- With checkpoint: Auto-saves every paragraph → won't lose much content
What are the benefits for users?
- More reliable data persistence
- More reasonable database file size
- Safer data when unexpectedly closed
