== Better Threading Handling ==
Blender is now massively multi-threaded (that is, on multi-core CPUs, it can execute several tasks in parallel), its renders of course (since a loooong time ago), but also more recently its depsgraph and many other tasks.

This is raising an issue - having 8 to 16 threads running on an 8-core CPU is good, having 80 or more is bad, basically because all those threads will waste a lot of time waiting for the right to use a CPU core, and because thread managing and context switching costs a fair amount of CPU time…

Main cause of that exploding number of threads is the usage of OpenMP, which is a library that makes it really easy to parallelize the execution of small chunks of code. So a (long-run, non-urgent) task was decided, to replace those OMP usages by proper calls to our own multi-threading code, which ensures we never get too much threads running.

So far, here are the tools/area of Blender which have been updated:
*Modifiers:
**Ocean (~22% speedup), {{GitCommit|rBb36a0c44bb1ca}} and {{GitCommit|rB1eed354e530f395}}.
**UVWarp (~12% speedup), {{GitCommit|rB4d5b7feddea1}}.
**Vertex Weight Proximity (~5% speedup), {{GitCommit|rB95bc8389a983}}.

*Paint/Sculpt (WIP):
**All of sculpt/paint code, speedup is heavily variable, from unnoticeable to above 20% in best cases (global stroke processing), and some post-processing also had some speedup (like normals update, which is now 20% quicker). {{GitCommit|rB1991ee173865}}, {{GitCommit|rB2e77c413ab3cdc}}, {{GitCommit|rB0b157f7c6cf3b}}, {{GitCommit|rBa5c419f4ccb}}, {{GitCommit|rB6703d413f9b3}}, {{GitCommit|rBb871160dd}}, etc.

*Misc:
**Smoke simulation (~5% speedup), {{GitCommit|rBf30b0c60cffc}}.
**Particle internal code, {{GitCommit|rBc1b76285eef7ab}}).
**Some low-level 'library' code, gives e.g. ~2% speedup to Cloth simulations (but affects several other parts of Blender), {{GitCommit|rBd08e9883bdfc}}, {{GitCommit|rB971f9e1c25dae}}.

== Compositing ==

* Add Invert option to the 2D stabilization node ({{GitCommit|ea67f55}})
* Use mask name as mask node label ({{GitCommit|f1555c8}})
* Expose track velocity as an output of Track Position node (speed is measured in pixels per frame) ({{GitCommit|2339a84}})
* Add option to extend image bounds when blurring ({{GitCommit|cc55f97}})

== Image Editor ==

* Make it possible to visualize individual R,G and B channels ({{GitCommit|43bf78c}})

== Various ==

* Fix and re-enable 'redirection' to translated manual when using translated UI ({{GitCommit|rBA9a875bfb2693}})
* Add object mode select more/less {{GitCommit|de79d04}} ({{GitCommit|3097119}})
* Support for copy/paste the groups of objects ({{GitCommit|90250f8}})
* Transform: Support storing virtual cursor location.<br>Grabbing now doesn’t ‘jump’ when shift is released (matching rotation modes) ({{GitCommit|e6abc3a}}).
* Blender Internal: subframe render support {{GitCommit|63de1e7}}

== OpenVDB caching ==

Smoke simulations can now be cached using OpenVDB as a back-end ({{GitCommit|rBe9452f909cdb}}).
The simulation fields can be found in the .vdb files under the following names:
* "color"
* "density"
* "heat"
* "heat old" (the temperate at the previous fame)
* "flame"
* "fuel"
* "react" (reaction coordinates, used for fire)
* "velocity"
* "shadow" (the shadows of the volume computed for viewport rendering)
* "texture coordinates" (used for turbulence)

'''Notes:'''
* The presence of a given field depends on the simulation settings, e.g. "texture coordinates" is only written if high resolution is enabled
* If high resolution is enabled, the corresponding low resolution fields are suffixed with " low".

== Vector Transform node support for Viewport and BI ==

({{GitCommit|rBa6aaaad9795e}})

== Cubemap world textures in BI viewport ==

Cubemap world textures are now supported in the Blender Internal engine viewport. ({{GitCommit|rB771f73b6bedb}})

'''Notes:'''
* The image type has to be Environment Map
* The environment texture format is the format of the environment textures created via Blender
* 'World Background' Display option turned on
* 'Horizon' influence of texture turned on

== Cubemap reflections in the viewport and in the game engine ==

Cubemap reflections are now supported in the viewport and in the game engine. ({{GitCommit|d80f8ba}})

'''Notes:'''
* The image type has to be Environment Map
* The mapping coordinates have to be set to "Reflection"
* The environment texture format is the format of the environment textures created via Blender
* Geometry options are not available for environment textures, but the reflection can be deformed by a normal map texture
* The reflection deformations depend on the textures stack order (the normal map has to be in a slot < environment texture slot)

== Rectangle and Ellipse shapes for spotlights ==

The spotlights can now be scaled on one or several axis. This works both for elliptical and rectangular spotlights.
The current python API to scale objects can be used. ({{GitCommit|e60d535}})

== Text objects native clipboard integration==

The text objects copy/paste functionality is integrated with the system clipboard. When pasting text, the style (bold, material, ...) is maintained, if it was originally copied from Blender. ({{GitCommit|a143aeae}})
