When using one of the "Delete All" shortcuts from the context menu, you will now be presented with a confirmation pop-up to confirm you would indeed like to actually delete all tokens, maps, drawings, etc. This is to prevent you from accidentally deleting lots of things when you were in fact trying to just create a note or token. If you find this to be annoying, you can disable the pop-ups in the preferences section of the settings.
At some point, the website that hosted the reference documentation for using the Dice Roller went offline, so the link from GATE led to a dead website. Thanks to the Internet Archive's Wayback Machine, I was able to recover the documentation and host it on Banshee Cat's servers instead. The button now redirects there instead.
