What's New in v1.7.0?

Version 1.7.0 is a major stability update fixing 11 bugs including 3 critical issues that could cause data loss and server lag. This update is highly recommended for all users.

Critical Bug Fixes

1. Data Loss Prevention
Entries are now saved to database before memory cache, eliminating data loss during database failures. No more lost changelog entries when MySQL connection drops!

2. DoS Protection
Added content length validation (3-5000 characters) to prevent oversized entries and server lag. Protects against players spamming massive changelog entries that could crash your server.

3. Database Garbage Collection
Soft-deleted entries are automatically pruned after 30 days, preventing infinite database growth. Your database will stay clean and performant over time.
