Version 2.0.9 is now out. The main focus of this release is improved graphics tablet support. If you've been having problems using a graphics tablet with Drawpile, there's a good change this version will fix them.
Drawpile now uses Krita's new Windows Ink support code (good news for all Surface Pro users!), as well as their improved Wintab and XInput2 tablet event handlers.
After updating, remember to try unchecking the "enable bug workarounds" setting. Chances are you won't need it anymore.
