Supported Python version policy

[colin-pm]

At the end of 2022, EOL Python versions will be dropped. Starting in 2023, HVAC will track with the CPython Release lifecycle. This decision was made to track with dependencies that track the CPython Release lifecycle. For reference, the next dates are listed below.

• Python 3.6 will be dropped 31 Dec 2022
• Python 3.7 will be dropped 27 Jun 2023
• Python 3.8 will be dropped 14 Oct 2024

It's been a while since we commented on this issue. I will add that we will remove Python versions in major version releases of hvac only unless there is a compelling reason we need to do so earlier.

New versions of Python may become supported in minor releases.

Update on schedule

Since we're behind schedule and the 3.7 EoL date is approaching, we will drop support for both Python 3.6 and Python 3.7 in v2.0.0.

Python 3.11 support is expected to be added in the same release (we cannot add it earlier due to dependency conflicts with Python 3.6)

• CI: Add 3.11 support #915

The v2.0.0 milestone can be followed here:
