kivy v1.11.0 Release Notes

Release Date: 2019-06-01 // almost 5 years ago

  • 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.

    Other

    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.
