This new update bumps PawPaint from v1.0.84 to v1.0.93 with some changes. The patch notes are as follows.
CHANGES MADE:
A new "Emission" channel has joined the default channel list.
Added custom channel creation, painting and saving.
Added a new "Project" window, which is nested with the "Layers" panel. Add, delete or modify channels from here, including custom ones.
Added bloom (on by default) to display emission. Customizable from the "Environment" tab.
Custom channels can be saved in material and stack presets, and will ask you if you want to add or skip missing channels when applying from the library.
