The shuffle table may not act as expected & is still to be finished being re-worked. This was also present in the 216xx builds & possibly 215xx.
SNSF sets won't play correctly or at all which is still to be investigated fully.
The Not So Neo output plug-in won't maintain user output modes & will reset to what's being input which is an unwanted side-effect of trying to resolve issues when 'as-is' was set & the input changed. Post-release updates have been provided which should resolve this & other issues with this plug-in.
If the active window is changed whilst a Ctrl+Tab related action occurs it is possible for it to get stuck in an endless loop which'll then cause an unresponsive crash to occur.
