# offline-editor-js - Changelog # offline-editor-js - Changelog
## Version 3.4.0 - September 13, 2016
Possible breaking changes.
**Enhancements**
* Added base64 re-encoding to the tile database that results in a 2.7x (16/6) reduction in storage size.
**Known Issues**
* Firefox v48.x is showing tiles as hidden when they should be visible. This issue existed at v3.3.2.
## Version 3.3.2 - August 24, 2016 ## Version 3.3.2 - August 24, 2016
No breaking changes. No breaking changes.
