3.38.0 - 2020-09-12
-------------------

* Python 2 is no longer supported.

  Note for distros/packagers:
      In case you want to keep Python 2 support you'll likely split any existing
      package into a Python 2 and 3 version. Since these aren't parallel installable
      here are some recommendations on how to make it work:

      * Build the devel package from the Python 3 source package
      * Drop the headers/.pc files from the Python 2 build/package
      * Make sure no Python 2 using package depends on the devel package
        (@Arch: gnumeric can be build without Python support for example)

      See :issue:`392` for details

* gdk overrides: Fix wrapping of scroll events :mr:`141`
