I just pushed a commit bumping the version number to **v1.1.0**. This is the first stable release of PyUAVCAN (v1.0 was never published due to legacy reasons), and the second implementation of UAVCAN v1.0 to reach stability (after [Libcanard released a few months ago](https://forum.opencyphal.org/t/libcanard-for-uavcan-can-v1-is-released/774/29)). There are no major changes compared to the previous pre-releases.

PyUAVCAN v1.1 is a full rewrite of the legacy PyUAVCAN v0. The rewrite project was commenced about 1.5 years ago:
