+## Description
+
+This node evaluates the location, rotation, and scale fcurve at a specific
+frame, returning the transformation of the object at that frame.
+
+## Option
+
+- **Offset** - The input frame is relative to the current frame. So an
+    input frame of 5 with the current frame at 5, the actual evaluation
+    will be at frame 10.
+- **Absolute** - The input frame is the frame at which evaluation will
+    happen.
+
+## Inputs
+
+- **FCurves** - A list of fcurves from which the transformation fcurves will be
+  evaluated. Non transform fcurves will be ignored.
+- **Frame** - The frame at which the fcurve is evaluated.
+
+## Outputs
+
+- **Matrix** - The evaluated transformation in the form of a matrix.
+- **Frame** - The input frame delayed by the duration of the fcurve.

+## Evaluate FCurves Transforms
+
+A new *Evaluate FCurves Transforms* node was added to evaluate location,
+rotation, and scale fcurves at an arbitrary frame.
+
+{{< video evaluate_fcurves_transforms.mp4 >}}
+
+## Auto Execution
+
+A new *Scene Changed* option was added to the Auto Execute panel. This option
+makes Animation Nodes execute if anything changes in the scene, which is much
+more efficient that the existing *Always* which superfluously executes in most
+cases. This is now the default.
+
+## 3D Viewer
+
+The *3D Viewer* node now allows viewing splines.
+
+![3D Viewer](3d_viewer.png)
+
+## MIDI
+
+The *Evaluate MIDI Track* node now supports controlling the *Decay* time as
+well as its interpolation and the *Sustain* level. So it now supports the full
+ADSR envelope. The node now also have a new *Velocity Sensitivity* input, which
+attenuates the MIDI note values by their velocity if 1, does nothing if 0.
+
+## Attributes
+
+The *Insert Custom Attribute* node now allows overwriting existing attributes.
+
+Input and output mesh nodes now support built-in attributes.
+
+![3D Viewer](builtin_attributes.png)
+
+## Object Instancer
+
+The *Add To Main Container* advanced option was replaced with a *Container
+Type* option, which specifies where the new instanced objects will be added.
+They can be added to the *Main Collection* as before, to the *Scene Collection*
+of the scenes provides by the user through the *Scenes* input, or to the
+*Collections* provided by the user through the *Collections* input.
+
+## Lamp Data
+
+A new *Lamp Input* and *Lamp Output* nodes were introduced to get and set lamp
+data like Color and Energy.
+
+## Vectorization
+
+The *Get Spline Length* and *Float To Text* nodes were vectorized.
+
+## Optimizations
+
+Animation Nodes no longer setup unused subprograms, so it should be much faster
+for files with many node trees with subprogram assets.
