Broken: version: 2.82 (sub 0), branch: master, commit date: 2019-10-15 12:59, hash: rB6934688f2ca1
Worked: (optional) Before outliner commits iirc (the commits from Nathan Craddock if I remember correctly.
Short description of error
The behaviour to select several objects in outliner changed.
I don't know if this is a bug.
Exact steps for others to reproduce the error
In 2.79b, when you were selecting several objects in outliner with shift + left click, the last object selected became the active object (OBACT(view_layer) maybe?).
In 2.8, we have not the same behaviour when we select multiple objects with shift + click.
This issue is happening since Nathan Craddock commits about outliner iirc (not 100% sure).
Here is a GIF to illustrate the issue:
Parenthesis: I am using 2.7 keymap if others can't reproduce the issue
