Deprecated classes and functions

• #1616: Remove all functions and classes that were deprecated until v0.6.0

New features

• #1716: Rewrite stroke and fill shaders

  Rewrite vectorized mobject shaders to be compatible with transformation matrices.

• #1695: Add option to justify text with MarkupText

  A new parameter justify is added to MarkupText. It can be used to justify a paragraph of text.

• #1660: Added support for .webm and transparency of videos in Jupyter notebooks

  • Added support for generating webm videos via the command line flag --format=webm

  • Added transparency support for Jupyter notebooks

• #1553: Add dearpygui integration

Enhancements

• #1728: Improved positioning and size of the OpenGL window; added some configuration options

• #1733: Let OpenGLMobject.copy return a deep copy by default

• #1735: Metaclass compatibility for coordinate_system.py, Code and ParametricSurface

• #1585: OpenGL compatibility via metaclass for Matrix, DecimalNumber, Variable

• #1713: Exit the command line interface gracefully if no scene was chosen

• #1652: Refactored Mobject and Scene to no longer inherit from the abstract base class Container

  • Moved tests in test_container.py for Container that test Scene and Mobject to their own files.

  • Corrected various instances of incorrectly passed keyword arguments, or unused keyword arguments.

• #1693: Made the default arrowhead size for Arrow3D smaller

• #1678: Allow some rate functions to assume values outside of [0, 1]; introduce clamping decorators

  • Fixed animations so that certain rate functions (running_start, wiggle, ease_in_back, ease_out_back, ease_in_out_back, ease_in_elastic, ease_out_elastic, and ease_out_elastic) can go outside the range from 0 to 1.

  • Fixed lag ratios so that they’re spaced out evenly within the time interval and the rate functions are applied to each animation individually, rather than having the rate function determine when the animation starts.

  • Fixed faulty code for ease_in_out_expo, ease_in_bounce, ease_out_bounce, and ease_in_out_bounce.

• #1649: Made video file names in Jupyter notebook more readable

• #1667: Determine the default number of decimal places for NumberLine labels automatically from the step size

  As an example: If the step size is set to 0.5, labels will now show at least one decimal place.

• #1608: Color file paths in terminal; remove curly braces surrounding the file path in “Partial movie file written in…” messages

• #1632: OpenGL compatibility via metaclass: Group
