Highlights

  • :pr:1677: Added a new :class:~.Table mobject This brings easy-to-use and customizable tables to Manim. Several examples for this new mobject can be found at :mod:the module documentation page <.mobject.table> and its subpages.

Deprecated classes and functions

  • :pr:1848: Deprecated parameters for :class:~.DashedLine and :class:~.DashedVMobject

    • dash_spacing is an unused parameter
    • positive_space_ratio has been replaced with the shorter name dashed_ratio

  • :pr:1773: Remove all classes and functions that were deprecated until v0.7.0 and v0.8.0 The classes FadeInFrom, FadeOutAndShift, FadeOutToPoint, FadeInFromPoint, FadeInFromLarge, VFadeIn, VFadeOut, VFadeInThenOut have been removed, use :class:~.FadeIn or :class:~.FadeOut with appropriate keyword arguments instead.

    The classes CircleIndicate, ShowCreationThenDestruction, AnimationOnSurroundingRectangle, ShowPassingFlashAround, ShowCreationThenDestructionAround, ShowCreationThenFadeAround, WiggleOutThenIn, TurnInsideOut have been removed. Use :class:~.Circumscribe, :class:~.ShowPassingFlash, or :class:~.Wiggle instead.

    The classes OpenGLTexMobject and OpenGLTextMobject have been removed, use :class:~.MathTex and :class:~.Tex instead. Also, VMobjectFromSVGPathstring has been removed, use :class:~.SVGPathMobject instead.

    Finally, the utility functions get_norm and cross have been removed (use the corresponding Numpy methods instead), and the function angle_between has been replaced with angle_between_vectors.
