#2550: New thematic guide: a deep dive into the internals of the library
This new thematic guide aims to be a comprehensive walkthrough describing all the things that Manim does when you run it to produce a video.
#2732: Improved overall structure of deployed documentation; added a dedicated FAQ section
#2749: Added ChangeSpeed, an animation wrapper that allows to smoothly change the speed at which an animation is played
The speed of any animation can be changed by wrapping the animation with ChangeSpeed and passing a dictionary as speedinfo whose keys are the relative animation run time stamps and whose values are the absolute speed factors; e.g., {0.5: 2, 0.75: 0.25} smoothly speeds up the animation by a factor of 2 once it has been completed to 50%, and then it is smoothly slowed down to 1/4 of the default run speed after 75% of the animation are completed. The run_time of the animation will be adjusted to match the changed play speed.

It is also possible to add time-based updaters that respect the change in speed, use the auxiliary ChangeSpeed.add_updater() method to do so.
