v2.0.0

[2.0.0] - 2023-04-28

Added

• Ability to override the time function by setting PID.time_fn to whichever function to use
• Black is now run in CI to detect formatting problems
• Project is now defined by a pyproject.toml file instead of the old setup.py. The setup.cfg file remains for flake8 configuration for now.
• Ability to give the PID a starting guess for its output, when you start controlling a system that is already at the setpoint and don't want the PID to start outputting 0
• Option for specifying differential_on_measurement, to choose between calculating the derivative term on the input (default) or on the error (classic PID)

Changed

• Rename the module PID to pid to avoid the shadowing from the PID class - potentially a breaking change in some edge cases
• CI migrated from Travis to GitHub Actions
• The documentation has gotten an overhaul and a new look. Much of the detailed documentation in README.md has been moved to a dedicated user guide.

Fixed

• Fix mypy issue by explicitly exporting PID
• Remove duplicated definition of output_limits in type stubs

Deprecated

• Official support for Python 2 is dropped. While the code will likely keep working in Python 2 going forward, it's no longer tested in CI and no guarantees are given.
