Pyodide Deprecation Timeline

Pyodide Deprecation Timeline#

Each Pyodide release may deprecate certain features from previous releases in a backward incompatible way. If a feature is deprecated, it will continue to work until its removal, but raise warnings. We try to ensure deprecations are done over at least two minor(feature) releases, however, as Pyodide is still in beta state, this list is subject to change and some features can be removed without deprecation warnings. More details about each item can often be found in the Change Log.

314.1.0#

  • jsproxy.as_object_map() will be removed. Use jsproxy.as_py_json() instead.

0.25.0#

  • Typescript type imports for PyProxy subtypes from pyodide will be removed.

  • The methods PyProxy.supportsHas, PyProxy.isCallable, etc will be removed.

  • Support for the homedir argument will be removed in favor of env: {HOME: "/the/home/directory"}.

0.24.0#

  • The messageCallback and errorCallback argument to loadPackage and loadPackagesFromImports will be passed as a named argument only.

  • Py2JsResult will be removed.

  • The --output-directory argument to pyodide build will be removed.

0.23.0#

  • Names that used to be in the root pyodide module and were moved to submodules will no longer be available in the root module.

  • The “message” argument to PyProxy.destroy method will no longer be accepted as a positional argument.

0.21.0#

  • The globals argument to runPython and runPythonAsync will be passed as a named argument only.

  • The extractDir argument to unpackArchive will be passed as a named argument only.

0.20.0#

  • The skip-host key will be removed from the meta.yaml format. If needed, install a host copy of the package with pip instead.

0.19.0#

  • The default working directory (home directory) inside the Pyodide virtual file system has been changed from / to /home/pyodide. To get the previous behavior, you can

    • call os.chdir("/") in Python to change working directory or

    • call loadPyodide() with the homedir="/" argument

  • When a JavaScript function is called from Python, PyProxy arguments and return values will be automatically destroyed when the function is finished.
