Hi everyone!

Today we're releasing the first patch-level release of Babeltrace 2.0

What's new since Babeltrace 2.0.1?

This release contains the following note-worthy fixes:

  - Fixed a segmentation fault when trying to instantiate a trimmer
    downstream of a component that creates streams without packets.
    See 5cf4fb3d2 [1].

  - The trimmer component class rejected streams that are not
    packetized. Since the trimmer supports streams without packets,
    there is no reason to reject them.
    See a26dd09ff [2].

  - The configure script silently accepted invalid Python
    configurations such as building with `--enable-python-plugins`,
    but without `--enable-python-bindings`, which resulted in users
    being unable to import the `bt2` package.
    See 3530dd01a [3].

The full change log follows.
