It is with extraterrestrial excitement that I announce the next release of Slipshow:

# Slipshow 0.9.0: Manim Black

The featured new feature of this release is the ability to easily integrate [Manim](https://www.manim.community/) videos in your presentation.

Note that, compared to just playing a video, you can schedule pauses, go faster to the next pause, and go back to the previous pauses, as showcased below.
