+Release version 0.14.0
+----------------------
+
+* Samples
+  - [sample_fbx2mesh] Supports vertices part of a skinned mesh but with a weight of 0.
+  - [sample_fbx2mesh] Assigns non-influenced vertices to root joint.
+
+* Library
+  - [offline] #124 Fixes incorrect root joint detection bug in glTF importer.
+  - [offline] #129 #130 Copy animation name to output in ozz::animation::offline::AdditiveAnimationBuilder.
+  - [animation] #103 Allows move constructor and assignment for ozz::animation::Skeleton, ozz::animation::Animation and ozz::animation::Track.
+  - [animation] Renames SamplingCache to SamplingJob::Context.
+  - [animation] #110 Renames skeleton bind pose to rest pose, to avoid confusion with skinning bind pose.
+  - [base] Fixes Float4x4::FromEuler which was swapping pitch and roll.
+
+* Build pipeline
+  - Moves CI to github actions.
+  - #59 Adds support for shared libraries on Windows (dll), Linux and MacOS platforms.
+  - #111 Removes _GLIBCXX_DEBUG from default build settings as it can create incompatibilities when using prebuilt packages.
+  - #122 #137 Adds support for gcc 11 compiler.

 * Library
   - [animation] Adds two-bone and aim inverse kinematic solvers. They can be used at runtime to procedurally affect joint local-space transforms.
-  - [animation] Allows resizing SamplingCache, meaning the can be allocated without knowing the number of joints the cache needs to support.
+  - [animation] Allows resizing SamplingJob::Context, meaning the can be allocated without knowing the number of joints the cache needs to support.
   - [animation] Allow ozz::animation::LocalToModelJob to partially update a hierarchy, aka all children of a joint. This is useful when changes to a local-space pose has been limited to part of the joint hierarchy, like when applying IK or modifying model-space matrices independently from local-space transform.
   - [animation] Changes ozz::animation::Skeleton joints from breadth-first to depth-first. This change breaks compatibility of previous ozz::animation::offline::RawAnimation, ozz::animation::Animation and ozz::animation::Skeleton archives.
   - [animation] Renames track_triggering_job_stl.h to track_triggering_job_trait.h.

 ## Description
 
-Additive blending is a key concept in run-time animation. By superimposing a movement on top of a playing animation, it allows to add variety while lessening animation count and complexity.
+Additive blending is a key concept in run-time animation. Superimposing a movement on top of a playing animation allows to add variety while lessening animation count and management complexity. In this sample, 2 *splay* and *curl* hand animations are a added to a *walk* cycle. A weight is associated to each additive layers independently, allowing to control fingers.
-In this sample, a "cracking head" animation is added to a "walk" cycle. Note that no synchronization is required between the two animations.
 
 ## Concept
 
-Additive blending is different to normal blending because it does not interpolate from a pose to an other. Instead it combines poses, meaning you can see the two animations at the same time. In this example the walk cycle is never altered. The cracking head and shoulder movements from the additive animation are simply (visually speaking) added.
+Additive blending is different from normal blending because it does not interpolate from a pose to an other. Instead it combines poses, meaning the two animations can be seen at the same time. In this example the walk cycle is never altered. Fingers curl and splay poses coming from the additive animation are simply added (visually speaking) to the base animation. For the purpose of this sample, only the first frames of the 2 additive animations are used, aka a fixed pose for each (curl and splay poses).
 
-Additive blending is performed by ozz::animation::BlendingJob. ozz::animation::BlendingJob exposes additive layers with the same input as normal blending layers: per joint local transforms, a global layer weight and optional per-joint weights. The main differences are that additive blending is done at the end of the normal blending pass, with a different equation.

-The additive (or delta) animation is created by subtracting a reference pose from a source animation. ozz proposes a ozz::animation::offline::AdditiveAnimationBuilder utility to build additive animations. It uses the first frame of the animation as the reference pose. fbx2ozz supports additive configuration option to export delta animations from a source file.

-Additionally, the sample uses an optional mask to blend the additive animation on the character upper body only. See partial blending sample for more details.
 
 ## Sample usage
 
-The sample proposes to modify main and additive layers weights:
+The sample proposes to tune base and additive (curl & splay) layers weights. Additive layers weight are exposed via 2d slider to make it easier to control together.
-- Normal blending layer weight.
-- Additive blending layer weight.
-- Upper body masking activation and base joint selection.
-
-Both main and additive animation playback parameters are exposed.
 
 ## Implementation
 
-1. Loads main, additive animations, and their skeleton. See "playback" sample for more details.
+1. Loads base, additive (curl and splay) animations, and their skeleton. See "playback" sample for more details.
-2. Samples each animation to get local-space transformations. Sampling an additive animation is not different from a standard one.
+2. At initialization time, the first frame of curl and splay animations are sampled in order to extract their respective local-space transformations. Sampling an additive animation is not different from a standard one. The 2 animations are deleted as only the extracted pose will be used further. 
-3. Setups ozz::animation::BlendingJob object. BlendingJob object takes as input two arrays of BlendingJob::Layer, one for standard blending, the other for additive blending. Each layer is setup with its weights and the local-space transforms outputted from the sampling stage.
+3. At runtime, base animation is sampled to get skeleton base local-space transformations.
+3. Setups ozz::animation::BlendingJob object. BlendingJob takes as input two arrays of BlendingJob::Layer, one for standard blending (base animation sampling output), the other for additive blending (the 2 curl and splay poses). Each layer is setup with its weights and the local-space transforms.
 4. Convert local-space transformations to model-space matrices using ozz::animation::LocalToModelJob. It takes as input the skeleton (to know about joint's hierarchy) and local-space transforms outputted from the blending pass. Output is model-space matrices array.
-5. Model-space matrices array is then used for rendering skeleton posture.

BlendingJob object takes as input an array of BlendingJob::Layer representing each layer to blend: weight and local-space transformations (as outputed from the sampling stage). It also takes as input the skeleton bind-pose, which represents the default transformation of each joint.
