I wasn't familiar with this template either, until someone showed me that my AWB bot did this:
https://en.wikipedia.org/w/index.php?title=Identity_(social_science)&type=revision&diff=1122538200&oldid=1122514514&diffmode=source

It's been a year since this task was created. Could we please get an update?

For another example, try running AWB on [[Peter Brook]].
AWB tries to move {{About}} above {{hatnote group}}

Another bad edit: https://en.wikipedia.org/w/index.php?title=Mathematics&diff=1130543989&oldid=1130375903&diffmode=source

Note that a year ago, there were around 40 transclusions of this template. Now there are 300 and this is causing problems much more frequently.

Another bad edit: [[Special:Diff/1141271817]]

Another bad edit: [[Special:Diff/1171386250]]. I added {{hatgrp}} --> {{hatnote group}} to [[WP:AWB/TR]] in anticipation of the fix for this issue.

Another bad edit: [[Special:Diff/1177545490]]. There are now 655 transclusions of {{hatnote group}}. Looking forward to a fix soon!

@Reedy - Could you please release a new version of AWB with this fix included? I keep getting complaints of bot edits that mess up this template. Thanks!

Why is this task marked as resolved when AWB has not yet been updated?
(@Reedy not being around to make an update is unfortunate, but the solution to the underlying problem is not for Reedy to reappear and release a new version — it's for us to move away from a non-web-based implementation of AWB that has only major releases and that has a bus problem.)

Tasks are resolved when the code is updated, not when a release is made.

@Sdkb - For an unofficial release that contains this fix, see [[:en:Wikipedia talk:AutoWikiBrowser#Unofficial release]]

I appreciate the link, @GoingBatty, but see my comment here.
