Seems to work as expected. Can you reproduce the bug in a newer build?

D4193 hasnt been commited yet [and needs an update as well -- will look at that shortly], so will reopen for now...

Thank you all for your incredibly fast fix. I added the lines and It works!
This is also my first own blenderbuild. Fantastic!
ThumbsUp

i've just found this problem - keyframing renderability for a Plane object and a Point Lamp are not working in an animation file that worked at 2.79

Still don't work with today build (downloaded from blender.org / beta section / windows 64).

If you go to editmode and change the curve , the hair will only update after switching back to objectmode.
It is immedeatly updating in blender 2.79 which is great.

Really hoping this is fixed soon. It feels like a basic feature for all animators.

@Sergey Sharybin (sergey): just letting you know this gets reported quite often...

the image above already shows my simplified bug. Add a curve, subdivide it twice in edit mode, select the first contol point and hit ctrl-h.

Can you reproduce the error in a new file?

No worries - this area is not so easy to control. Particle nodes FTW :)

I found the issue, but it is too embarrassing to tell. Sorry 1000 times!

@William Reynish (billreynish) Please use my blendfile and tell me if you can do them upright in 2.8. My particles aren't objects but groups (collections).

I can't really reproduce. This was the case in 2.79 too.

at least, when i subdivide a curve twice and then try to create a hook at the first point, it gets shifted away from the point:

Are you sure that you did not accidentally hooked all points to this empty?
The fact that this empty is exactly in the center of all curve points (in edit mode) also supports this claim.

Thing is, rotation belongs to particleSettings data-block, while seed belongs to Object data-block (through ParticleSystem data). Those do different things in particle_recalc() update callback, and depsgraph also uses different components (see depsgraph_tag_to_component_opcode() in depsgraph_tag.cc).

All right Brecht. Thank you for the note.

No need to assign tasks to developers, we will do that.

Most operators appear to be working, and we will use bug tracker to handle remaining issues.
