I just merged [#132](https://github.com/UAVCAN/pyuavcan/pull/132), which fixed eight outstanding issues and introduced a couple of UX improvements. All these have been discussed on this forum and on GitHub a number of times. This release is fully compliant with Specification v1.0-beta.

Grab your copy from PyPI:

```auto
pip install pyuavcan[transport_serial,cli]

```

Just tried it out, still got issues, just a bit different as described [here](https://forum.opencyphal.org/t/viper-quadcopter/816/43).

```bash
$ pyuavcan publish 32085.uavcan.node.Heartbeat.1.0 '{uptime: 9876, health: 0, mode: 3, vendor_specific_status_code: 5}' --tr='CAN(can.media.socketcan.SocketCANMedia("vcan0",8),13)'
Error: TypeError: Invalid format: cannot update an instance of type 'Health_1_0' from value of type 'int'

Yup, it’s by design. You are saying:

```auto
{uptime: 9876, health: 0, mode: 3, vendor_specific_status_code: 5}

```

But the correct form is:

```auto
{uptime: 9876, health: {value: 0}, mode: {value: 3}, vendor_specific_status_code: 5}

```

The error message is saying that it expected `{value: X}` but got just `X`.
