Change log / notes
==================
** January 2020**
Added experimental [Trio](trio.readthedocs.io) support for the `pull` command
which enables pads to be processed concurrently. The default `--connection`
option is set to 20 which may overpower the target server. If in doubt, set
this to a lower number (like 5). This functionality is experimental, be
cautious and please report bugs!
**October 2019**
Improve `etherpump --help` handling to make it easier for new users.
