New in version 5.10
Breaking Change:
- Emergency
The "STIR" option is removed, replaced by a "priority" box. To always block calls that fail STIR, just increase the STIR priority.

Improvements:
- Rule priority conflict detection
The floating tube(test) button turns orange when conflicts are detected

Increase it to bypass the warning "Text too long, editing is disabled"
