Defocus not update when render animation,

recent blender build in september 2018 have bug with z dept pass.
i can’t report bug, because blender2.8 only accept crash not bug report.

bug : defocus not update when render animation.
i have blend file: bug dof

1.open and render animation(Ctrl F12).
2.view animation(Ctrl F11)
3.Dof didn’t update

my question is how to build blender 2.8 back to august.
thank…

or if this bug fixed. i will use recent build : ) @brecht

In general, to build an older version you need to find an older revision hash that you want to build (with git log for example), and then use git checkout <myhash> to check out that revision. If you have a Git GUI it should be even easier to look through the history and pick a revision to check out.

i try hash:ccc8d2ab42751b44eb54640842630354ff3902f9
date : 2018-08-14 14:41:19

but build error

LINK : fatal error LNK1181: cannot open input file ‘C:\blender-git\blender…\lib\win64_vc14\boost\lib\libboost_date_ti
me-vc140-mt-s-1_60.lib’ [c:\blender-git\build_windows_Full_x64_vc14_Release\source\creator\blender.vcxproj]
Error during build,

Ah, you’ll need to update the lib/win64_vc14 directory to a revision from the same date. In this case:

svn update -r 62070

thank @brecht . now i can build old blender2.8 version.

but bug dof still there in august build. i don’t remember what blender version dof work well when animation.
i hope this bug fixed soon.
thank
