Thanks! Let me know when it's worth trying a new build. Also, what is the impact of these changes? Are we expecting to see a noticeable code reduction or speed improvement. Or are these actual bug fixes? |
|
For now, it's a miscellaneous collection of low-impact patches and no critical bug fixes, so I don't think there's any particular reason to rush the build. |
