kivy v2.0.0 Release Notes

Release Date: 2020-12-10 // 12 months ago
  • πŸš€ The Kivy team is happy to announce the release of Kivy 2.0.0.

    Kivy is a full-featured framework for creating novel and performant user
    πŸš€ interfaces, such as multi-touch applications, released under the MIT license.
    🍎 The framework works on Windows, macOS, Linux, Android, iOS and Raspberry Pi.

    • πŸš€ This is the first release to not support Python 2.7 - hence the increase in Kivy's major version to 2. Currently supported Python versions are 3.6 - 3.9.
    • πŸ‘€ Installation has been largely simplified and all platforms now support a simpler pip install (see below).

    πŸ“š Installation instructions and Kivy documentation is available on the Kivy website:

    https://kivy.org
    

    πŸš€ or on GitHub.

    Installation notes

    🐧 Kivy can now be installed into your Virtual Environment on Windows, Linux, OSX, and RPi simply with:

    pip install kivy[base] kivy-examples
    # or to get the media dependecies as well
    pip install kivy[base,media] kivy-examples
    # or to get most kivy optional dependencies
    pip install kivy[full] kivy-examples
    

    * For the RPi, additional system dependencies should be pre-installed.

    πŸ“Œ These selectors allow specifying dependency categories, instead of having to pin Kivy's kivy_deps dependencies to specific versions. These selectors will install the proper dependency version to match Kivy's version.

    βž• Additionally, by default, Kivy will install the base dependencies even if base is not specified. In order to facilitate easier install for GUI installation users e.g. in PyCharm. However, this may change as pip evolves and base should be manually specified. Use pip's --no-deps flag to disable it.

    πŸ“š See the selector documentation for more details.

    πŸ‘€ Installation from source has also been simplified, relying on pip's pyproject.toml. See the simplified instructions.

    Highlights

    πŸ‘ [#6351]: Support for Python 2 has been dropped and Kivy source code is now incompatible with Python 2.

    πŸ‘ [#6368]: Support for async has been added to Kivy. Kivy can now run cooperatively, in the same process or thread as asynchronous code.

    πŸ‘€ We currently support the stdlib asyncio framework and the excellent trio framework. See the kivy examples for how to use it.

    Branching

    ⚑️ The new stable branch is now derived from the 2.0.0 tag. The oldest stable branch has been renamed to stable-1.11.1. If you still want to compile on android with this branch, use "kivy==stable-1.11.1" as requirement. We do not support previous versions, so if things doesn't work anymore due to changes in python-for-android, please take time to update your application.

Previous changes from v1.11.0

  • We are pleased to announce Kivy 1.11.0.

    Kivy is a full featured framework for creating novel and performant user
    πŸš€ interfaces, such as multitouch applications, released under the MIT license.
    🍎 The framework works on Windows, macOS, Linux, Android, iOS and Raspberry Pi.

    • πŸš€ This is the last release to support Python 2.7. The next release will only support Python 3.5+.
    • πŸš€ This is also the first release with Kivy wheels for Linux (3.5+ only, Windows and macOS already have wheels).
    • ⬆️ Windows dependencies are now under the kivy_deps.xxx namespace external to Kivy, rather than kivy.deps.xxx under Kivy. Whether you're upgrading Kivy, please pin the dependency versions when installing because Kivy binary dependencies are not generally backward compatible [#6312].
    • The kivy.garden.flower namespace is similarly being transitioned to the kivy_garden.flower namespace.

    πŸ‘€ See below for more details.

    Downloads and installation instructions are available on the Kivy website:

    https://kivy.org
    

    Installation notes

    🏁 Windows

    • [#6324]: We are transitioning the kivy Windows dependencies from the kivy.deps.xxx namespace stored under kivy/deps/xxx to the kivy_deps.xxx namespace stored under kivy_deps/xxx. Pip is sometimes not able to distinguish between these two formats, so follow the instructions below.
      • If you're not upgrading Kivy, please make sure to pin your kivy.deps.xxx==x.y.z dependencies to the versions that was on pypi when your Kivy was released so that you don't get newer incompatible dependencies.
      • If you're upgrading Kivy, manually uninstall all the kivy.deps.xxx dependencies because pip will not uninstall them when you're upgrading. Then re-install the kivy_deps.xxx dependencies as instructed on the Kivy website.
      • If you're installing the first time , simply follow the instructions on Kivy's website.

    🍎 Linux and macOS

    🍎 The new Linux wheels (#6248) can be installed with just pip install kivy, however, just like on macOS it comes without the Gstreamer dependencies so it has no video and minor audio support. For video/audio support, please install ffpyplayer and set KIVY_VIDEO=ffpyplayer in the environment, or install kivy using an alternative method that provides these dependencies.

    Highlights

    πŸ‘Œ Support

    πŸ”§ Configuration

    [#6192]: Support for environmental variables that control the config in the form of KCFG_SECTION_KEY has been added. E.g. setting KCFG_KIVY_LOG_LEVEL=warning in the environment is the same as calling Config.set("kivy", "log_level", "warning") or setting the log_level in the kivy section of the config to warning. Note that underscores are not allowed in the section names.

    Any key set this will way will take precedence on the loaded config.ini file. Support for this can be disabled by setting the enviornmental variable KIVY_NO_ENV_CONFIG=1 and the environment will not be read for configuration options.

    KV lang

    [#6257]: A new KV-Python integration event that fires when all the KV rules of the widget has been applied, on_kv_post, has been added to the Widget class. This event fires for a widget when all the KV rules it participates in has been applied and ids has been initialized. Binding to this event will let you execute code for your widget without having to schedule the code for the next clock cycle.

    Similarly, a new apply_class_lang_rules method was added to Widget that is called in order to apply the KV rules of that widget class. Inheriting and overwriting that method will give you the oppertunity to execute code before any KV rules are applied.

    Garden

    We are transitioning the Kivy garden flowers from the kivy.garden.flower namespace stored under kivy/garden/flower or ~/.kivy/garden to the normal python package format kivy_garden.flower namespace stored under kivy_garden/flower. With the new configuration, garden flowers will be pip installable, support cython flowers, and not require the custom garden tool.

    We're hoping to transition all flowers to the new format, however, for now many flowers still require installation by the garden tool.

    πŸ‘€ For users, see https://kivy-garden.github.io/index.html#generalusageguidelines. For developers, see https://kivy-garden.github.io/index.html#developmentguidelines for how to start a new flower, and https://kivy-garden.github.io/index.html#guideformigratingflowersfromlegacystructure for how to migrate existing flowers to the new format.

    Branching

    ⚑️ The new stable branch is now derived from the 1.11.0 tag. The oldest stable branch has been renamed to stable-1.10.1. If you still want to compile on android with this branch, use "kivy==stable-1.10.1" as requirement. We do not support previous versions, so if things doesn't work anymore due to changes in python-for-android, please take time to update your application.
