Yeah this is one of the pitfalls of using fast developing, fast fixes and changes upon request, open-source Blender. It can be a part-time job just trying to keep up with the changes… and that’s if you know where to look for documentation (if it exists).
This change has a doc trail, starting with the 2.60 release log > animation system improvements. It was an easy one to miss. I scour those logs!
It links to: (change is hiding in #5)
The change was done after this poll (13 replies):
Here’s a post after a disturbance in the force was noticed:
http://aligorith.blogspot.com/2012/01/help-my-animation-stopped-working-26.html bottom of page.
I got lucky finding Aligorith’s blog btw. I think I stumbled upon that through a google search last year. There’s lots of info in there about the animation system changes of the past year or so. It’s a personal blog so you have to use his tag links to find the good stuff.
Here’s another site I use in the effort to keep up. Thanks to MiikaH we now have an easy way to see the revision commit logs after a long time waiting since the last site with this feature went away.
Here I’ll just post his blog post. Find the links/rss feeds and more around there.
This kind of info and links should be a sticky thread here somewhere. Or is a non-sticky buried somewhere around here already? Or is it on a blog somewhere already? Probably. Who knows? It’s the nature of the beast I guess.
