This version contains 73 commits made by 9 committers.

The version contains, apart from bug fixes, 3 bigger items:

• The async clients have a new transport layer, with common reconnect, timeout etc.
• Precommit and ruff have been added to the CI as well as the local "git commit".
• Type hinting have been added to several modules
  Please make sure to have a look at API_CHANGES.rst to see the changes affecting applications.

Thanks a lot to all that helped make this release possible, especially all the new committers.

Version 3.4 will focus on:

• A rewrite of the simulator configuration and additional documentation with more examples
• A common message layer for the async clients
  the target for the release is July / August

Type hinting have been added to several modules

This is great, the new type hints found a bug in all my drivers using pymodbus.

Here was the old pymodbus code with no return type hint.

pymodbus/pymodbus/client/serial.py

Lines 75 to 76 in 67d875b

	async def close(self): # pylint: disable=invalid-overridden-method
	"""Stop connection."""

Here is the new pymodbus code with a return type hint of None

pymodbus/pymodbus/transport/transport.py

Lines 344 to 345 in cfc95c4

	def close(self, reconnect: bool = False) -> None:
	"""Close connection.

Here is my buggy code which calls the above method in pymodbus:

    async def _close(self) -> None:
        """Close the TCP connection."""
        try:
            await self.client.close()  # 3.x

With the new type hints mypy reported:
midas/util.py:138: error: "close" of "BaseTransport" does not return a value [func-returns-value]
The problem with the above code which had gone unnoticed until now, is that it shouldn't use await.

On second thought, I think this was actually an undocumented API change? In 3.2.0 it should be await self.client.close()
