Hi, all:

I've released b4 version 0.5.3, which offers a handful of bugfixes and 
small enhancements in the stable-0.5.y branch. This is expected to be 
the last release in the 0.5.x series.

Notable changes:

- properly grab cover letters that don't have a diffstat
- require that trailers are at least 2 chars long
- improve "b4 ty" on cherry-picked series
- fix some crashers

If you installed using pip, you should be able to upgrade using the 
following command:

  pip install --upgrade --user b4

Full shortlog is below.
