Timeline updates; Engine updates; Bug fixes.
This hasn't been documented yet. The documentation for the new bits of the timeline will be available on the next stable release.
In the mean time, you can set a list of space separated tags on a master keyframe by selecting it in the Timeline Bar and then changing the property in the Properties Bar.
To later use the tags in an event sheet, look for a few new conditions in the timeline plugin dealing with reaching keyframes, should be easy to spot them.
Would it be possible to add a parameter to the timeline action "Set time By Name" to include a "tag field" or a new action that is "set time by tag" so that we could jump to a specific tagged keyframe in the timeline?
Thanks Diego, I was looking for some button or something that would label a keyframe, or a special type of keyframe that i could move around with a tag in the timeline window to set where i wanted it to go. Its interesting that it's only tied to a master keyframe because if you want to put a tag somewhere in between two other keyframes it appears you need to set a redundant keyframe on one of the other properties of the object in order to create a master keyframe.
Would it be possible to add a trigger action "on tag reached" as well please :)
That already exists in the Timeline plugin as "On keyframe reached".
