Changes in Python for Unity

RELEASE NOTES

[2.0.1-preview.2] - 2020-02-13

This is a bugfix release for 2.0.0-preview.

FIXES

  • Improved handling of a Python installation that can't find its home. Unity now displays an error rather than crashing.
  • Fixed repeated registration of an OnUpdate callback.
  • Prevented the Python top-level menu being added by default. Unpack the sample clients manually from the Package Manager instead.
  • The tilde character (~) in Python path and site-packages is now interpreted as the user home directory on all platforms.
  • In the Python Console, Ctrl-enter with no selection now executes the entire script (Cmd-enter on macOS).
  • Fixed the year in 2.0.0-preview.6 release date below. It's already 2020 apparently.

[2.0.0-preview.6] - 2020-01-08

This is the first public release of Python for Unity.

SECURITY FIX

  • Earlier versions opened an internet socket that could let anyone connect. This has been replaced with a Unix domain socket, so file permissions are used. As a side effect, out-of-process performance is much faster.

[2.0.0-preview.3] - 2019-10-25

BREAKING CHANGE

  • The out-of-process API has been entirely rewritten. The new API supports multiple clients, and asynchronous calls. Clients written to the previous API will need to be updated.

NEW FEATURES

  • Python Console; find it in [menu]
  • Python for .NET updated to version 2.4.0

    • A fix to a crash when finalizing the Python interpreter on domain unload
    • A C# callback on Python for .NET shutdown

KNOWN ISSUES

  • There might be scenarios that still crash/hang Unity when running Python after reloading assemblies.
    • If your tools are affected by domain reload, consider using the RPyC architecture. Refer to the documentation for an example on how to use the RPyC architecture.

[1.0.0] - 2018-10-05

NEW FEATURES

  • added Python support in Unity for Windows and Mac

[All Versions]

  • Trying to call UnityEngine.Debug.Log (or its variants) with a python string that contains non-ANSI characters, will cause the following error: Python.Runtime.PythonException: TypeError : No method matches given arguments for Log. For example this can happen on a French language version of Windows when a socket connection fails with error: [Errno 10061] Aucune connexion n’a pu être établie car l’ordinateur cible l’a expressément refusée.
