0.4.0 (2020-07-16)¶

Significantly improved new Supercube device controller:
- more robust error-handling,
- status polling with generic Poller helper,
- messages and status boards.
- tested with a physical device,
Improved OPC UA client wrapper, with better error handling, incl. re-tries on concurrent.futures.TimeoutError.
SST Luminox Oxygen sensor device controller.
Backward-incompatible changes:
- CommunicationProtocol.access_lock has changed type from threading.Lock to threading.RLock.
- ILS2T.relative_step and ILS2T.absolute_position are now called, respectively, ILS2T.write_relative_step and ILS2T.write_absolute_position.
Minor bugfixes and improvements:
- fix use of max resolution in Labjack.set_ain_resolution(),
- resolve ILS2T devices relative and absolute position setters race condition,
- added acoustic horn function in the 2015 Supercube.
Toolchain changes:
- add Python 3.8 support,
- drop pytest-runner support,
- ensure compatibility with labjack_ljm 2019 version library.

Fix issue with reading integers from LabJack LJM Library (device’s product ID, serial number etc.)
Fix development requirements specification (tox version).

New devices using serial connection:
- Heinzinger Digital Interface I/II and a Heinzinger PNC power supply
- Q-switched Pulsed Laser and a laser attenuator from CryLas
- Newport SMC100PP single axis motion controller for 2-phase stepper motors
- Pfeiffer TPG controller (TPG 25x, TPG 26x and TPG 36x) for Compact pressure Gauges
PEP 561 compatibility and related corrections for static type checking (now in CI)
Refactorings:
- Protected non-thread safe read and write in communication protocols
- Device sequence mixin: start/stop, add/rm and lookup
- .format() to f-strings
- more enumerations and a quite some improvements of existing code
Improved error docstrings (:raises: annotations) and extended tests for errors.

Prevent an automatic close of VISA connection when not used.
Rhode & Schwarz RTO 1024 oscilloscope using VISA interface over TCP::INSTR.
Extended tests incl. messages sent to devices.
Added Supercube device using an OPC UA client
Added Supercube 2015 device using an OPC UA client (for interfacing with old system version)
