#3020: Rewrote Manim’s color system
This change removed the colour library as a dependency of Manim and replaced the internal handling of colors with the newly added ManimColor. This also adds hundreds of new predefined colors, see utils.color for more details. This should only be a breaking change if you have interacted directly with the colour module before. The general interface has been kept stable.

#3299: Added new manim checkhealth CLI subcommand
This adds a new command line interface subcommand which can be used to check whether a local installation of Manim has been configured correctly, and all required (and optional) dependencies are available. To try it, run it via manim checkhealth or python -m manim checkhealth.
#3427: New feature: rendered examples in documentation can now be run directly via binder
This adds a “Make interactive” button below the examples in our documentation that establishes a connection to binder such that examples can be modified and rerendered directly from your browser.
#3086: Introduced a new module typing for type hints
This also adds various type hints to integral parts of the code base.
#3322: Implemented auto-removal of auxiliary LaTeX files, enabled by default
This automatically removes auxiliary files creating during the compilation of LaTeX documents like .aux or .dvi files. This behavior can be controlled via the newly introduced no_latex_cleanup config key (False by default). On the command line, the autoremoval can be disabled via the --no_latex_cleanup CLI flag.
#3395: Added support for Python 3.12

#3361: Added three new rate functions
This adds the rate functions smoothstep(), smootherstep(), smoothererstep() based on the SmoothStep sigmoid functions.
#3264: Added new mobjects LabeledLine and LabeledArrow

#3190: Made CurvesAsSubmobjects mobjects compatible with input_to_graph_point()
#3226: Avoid using a mobject as a default argument of ArcBrace
#3366: Added spacing between values and unit in DecimalNumber
This adds the new keyword argument unit_buff_per_font_unit (default: 0, for backwards compatibility). Setting it to some positive number creates additional space between the numeric value and the displayed unit.

#3205: Fixed type hint of angle in Arc
#3210: Fixed DecimalNumber with show_ellipsis=True with the OpenGL renderer
#3211: Fixed display issues with custom labels for Axes with the OpenGL renderer

#3315: Fixed issue with parameter types in Scene.add_subcaption()
#3423: Fixed incorrect submobject count of multi-part Tex mobjects
This resolves various issues where formulas were not displayed completely, like it was the case with MathTex("1", "^{", "0").
#3284: Fixed LinearTransformationSceneExample in Jupyter notebooks
#3302: Fixed typo in comparison in OpenGLVMobject.interpolate()
#3340: Fixed incorrect computation of bounding box for rotated ImageMobject
#3343: Fixed return value of TexTemplate.add_to_preamble() and TexTemplate.add_to_document()
#3282: Ensure that ArrowVectorField.get_vector() does not modify the passed inputs
