Today's patch will more than likely break most, if not all interfaces. The update is to the Buff Window, Short Duration Buff Window, Target Window and the Templates file. They minimized the code of creating the buffs by using a template instead of 96 separate elements. This will allow the ability to also add in more buffs in the future without the need to edit the file again. However, as stated a while back... they are planning on re-designing the frontend UI system in 2023, so any updates from now until then will probably be minimal.

UI

• Accepting a resurrection will now update your respawn window selection to the location of your corpse.
• Fixed a bug that caused a crash when the Manage Loot window was being used.
• Fixed a notorious crash that occurred when changing filters in the Advanced Loot Window.
• Updated the /copylayout command to properly copy hotbutton window size, spinner, and keymap options.
• Converted the Effects, Short Term Effects, and Target windows to dynamically layout the positioning of effects and support a variable number of effects.
