Breaking changes

• #2898: Ported improved implementation of SVGMobject from 3b1b/manim

  The implementation of SVGMobject is completely changed in this release. Manim now uses the Python library svgelements to parse SVGs, instead of trying to do it itself. The former class for SVG path objects, SVGPathMobject has been replaced (without deprecation) with VMobjectFromSVGPath.

  If you need to create a mobject from an SVG path string, you can do so via:

  import svgelements as se
  my_path_mobject = VMobjectFromSVGPath(se.Path(my_path_string))
  

  The unused class TexSymbol has been removed. The modules manim.mobject.svg.svg_path and manim.mobject.svg.style_utils became superfluous due to the rework and have been removed.

• #3030: Added support for Python 3.11, dropped support for Python 3.7

Highlights

• #3049: Added thematic guide for the manim-voiceover plugin

  This new thematic guide provides a brief introduction to manim-voiceover, a plugin that helps to add voiceovers to your manimations. Supports both working with your own voice as well as synthetically generated voices.

Enhancements
