Fix: Smoke wasn't using pointcache properly.
* The cache was reset almost constantly because smoke didn't save the first frame into cache. Although not necessary for smoke, it's vital to pointcache.
* Added info message to smoke cache panel for non saved files.
* Now smoke also only updates with a framestep of 1, so that scrubbing the timeline doesn't mess up the simulation.
* Among other things fixes report #23731.

added CTX_wm_operator_poll_msg_get/set so failing poll functions can set messages when poll fails, at the moment only python uses this but theres nothing python specific.

only added 1 message to a poll function, so messages still need to be set in many more places to be useful.

bugfix [#24009] Crash when switching area types and performing ops
tested every view3d operator to make sure none crash.

Fixed: Showing pointcached frames in the timeline was terribly slow when using disk cache.
* The existence of cached frames was checked each frame causing hundreds of disk operations per frame update.
* Pointcache now keeps an updated array of the cached frames for fast "frame exists in cache" queries.
* This fix also speeds up some other pointcache operations nicely.

bugfix [#23447] wrong vertices/edges selected in UV editor

Explicitely cast to MultiresModifierData pointer to silence compiler warning.

Fix: [#24006] writeffmpeg doesn't flush delayed frames - fix attached
and [#20843] FFmpeg H264 preset gives "Couldn't initialize codec"

Thanks to Leo Sutic for the patch!

show material hardness in solid shaded mode

use a struct for fixed materials rather then float[2][4], easier to follow (no functional change)

fix for floating point exception.

bugfix [#23995] Do loop cuts from the space bar search while in the properties panel crashes blender.

disable animating the camera lens angle, this way we dont have the problem where both lens and angle are animated
(2 fcurves accessing the same data), this should be handled by the units system but for now disabling this means we don't have to deal with animated angle later on.
note: durian files didnt use animated angle anywhere.

invalid name [#23986] Camera->Lens->Pespective->Angle input

bugfix [#24015] Deleting Objects with a Point Density Texture and Rendering Crashes Blender

bugfix [#24014] Operator UI not shown in the order defined

Fix typo that broke build on OSX.

OSX/Cocoa : discard Cocoa GL view flush while in live resize, and send Window size change ghost message only when user releases mouse button (not in live resize).
Potentially fixing bug [#23561]

- Save MDISPS layer when applying modifier.
All sculpting used to disappear before. Save MDISPS if new mesh has got the same faces amount.
NOTE: maybe some other layers should be saved?
- Apply multires modififier if MDISPS was auto-created.
Multires's applyModifier used to return unchanged DM when MDISPS was auto-created.
- Set multires totlvl from MDISPS layer when new multires was added to mesh with existing MDISPS layer.

Fix for [#23912]: Replace by integer comparison a float comparison whose precision errors was causing an infinite loop during last frame audio conversion
