A couple of weeks ago b10h4z4rd asked me to write something to help find scripts which were using deprecated functions and as we sensibly can't put attachments into PMs, I'm putting it here.
Working on the principle "if it ain't broke, don't fix it" I wouldn't suggest anyone else uses it.
For the record I've made it appear in the Help menu: Check for deprecated functions v1.0
It's a python script and I've only tried it on Windows XP, but it does work for both GIMP 2.6.7 & 2.8.2
If you tell it to, it creates a log file with this sort of output:
checking directory: C:\Program Files\GIMP 2.8.2\share\gimp\2.0\scripts
Checking 3d-outline.scm
Checking 3dTruchet.scm
==> Deprecated gimp-drawable-transform-flip-simple in 3dTruchet.scm
Checking add-bevel.scm
Checking addborder.scm
Checking alien-glow-arrow.scm
Checking alien-glow-bar.scm
Checking alien-glow-bullet.scm
==> Deprecated gimp-rect-select in alien-glow-bullet.scm
Checking alien-glow-button.scm
Checking alien-glow-logo.scm
