I have a reproductible crash with fewer steps.
Create a particle system on default cube.
Change amount to 10 000.
Switch emit source to verts. -> crash

David Morris (pixelgrapher) added a comment to T52434: Setting origin to Center of Mass on zero-volume objects produces wrong results now in 2.79.

In 2.79 RC2, it appears that repeating step 4 causes the origin to asymptotically move closer towards the center.

Brecht Van Lommel (brecht) reopened T48015: Banding artifacts in smoke viewport display as "Open".

This code has not been rewritten in Blender 2.8 as far as I know, can't assume this will be automatically fixed.

Maurice Raybaud (mauriceraybaud) closed T52397: Exported Hair Location wrong with inverted matrix as "Resolved".

Sorry but this bug was my fault: when adding inverted matrix, I initially forgot to test them with non textured hair and either missed that common use case or made a regression afterwards. Anys, the bug seems solved (for) now.

Brecht Van Lommel (brecht) added a comment to T52368: OSL trace not working in 2.79 RC!.

It indeed was not a bug in the actual 2.79 RC, so no need to backport this one. Also added test for this report.

Brecht Van Lommel (brecht) added a comment to T52368: OSL trace not working in 2.79 RC!.

Note the Blender version in the report is not the 2.79 RC build, it's a master build where confusingly the splash screen still shows "Release Candidate". So the crash might also be due to recent changes.

Please follow our submission template and guidelines and make a complete, valid bug report, with required info, precise description of the issue, precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.

Bastien Montagne (mont29) triaged T52224: Auto IK doesn't respect its Length setting as "Confirmed" priority.

Confirmed, looks like a regression (unless it was changed on purpose)… @Campbell Barton (campbellbarton) , @Brecht Van Lommel (brecht), think you are those who know that code best, mind checking? thanks.

Bastien Montagne (mont29) added a comment to T52222: Unexpected non integer values.

@Brecht Van Lommel (brecht) agree, actually that’s what I did in rBdc6fcb8ecff41e… But forgot about units cases (especially angles, which are somewhat in the middle btween 'regular' and 'units' number drawing :/ ). Shall be OK now though.

Brecht Van Lommel (brecht) added a comment to T52222: Unexpected non integer values.

Ah, it seems to be an issue with display of units in general. I'd still suggest to cap the number of digits shown at 6 instead of 7, that last digit being +-1 off from the value the user typed in is confusing.

Bastien Montagne (mont29) added a comment to T52222: Unexpected non integer values.

Eeeeh, angle buttons is actually an issue! Those go through the 'unit' path, which handles precision in the old, weird way - with max precision value :/
will fix that, should not be too hard…

Sun, Jul 30, 10:37 PM · BF Blender: Regressions, BF Blender
Brecht Van Lommel (brecht) added a comment to T52222: Unexpected non integer values.

I think the right behavior would be to show a number matching the one the user typed in, up to as many digits as we can preserve. The old code seems to round even 4.999 to 5.0, but we can keep up to 6 digits for floats, so 4.99999 can still work safely.

Feel free to revert if you like though, tbh I’m more than tired spending time on that kind of things, there is no good solution anyway, only better trade off or not.
