Version 3.0.0

This production release includes the interface additions and documentation clarifications for asynchronous behavior which are part of ASCOM Platform 7.

Changes since 2.0.4

• Added interface members as described in Release Notes for Interfaces as of ASCOM Platform 7 and published in November 2023 on the ASCOM Developer Forum. These have been included in the package unit tests and validated to the best of our abilities.
• Documentation of each interface member now contains a link to the corresponding member in the ASCOM Master Interfaces (Alpaca and COM) which serves as the definitive source of documentation (though it is generic and not Python specific).

Changes since 2.0.2 (2.0.3 unpublished)

• Switch interface now uses Id instead of ID for switch parameters. (GitHub Issue #8)
• Focuser.StepSize value type corrected to float (from int) (GitHub Issue #7)
• Documentation updated for changes in links to the Omni Simulator and other additions and corrections.

Changes since 2.0.1-rc1

• Fix discovery for multiple devices on localhost (GitHub Issue #6)
• Fix driveRates enum (GitHub Issue #3)
• Fix descriptive text for pierWest and pierUnknown (GitHub Issue #5)
• Fix DriverVersion to return the string (GitHub Issue #4)
• Camera.SensorTypes was corrected to Camera.SensorType in the interface
• Documentation corrections and clarifications

Changes since 2.0.0-dev2

• Improve speed via re-use of sockets (Connection: keep-alive) for device HTTP.
• ObservingConditions.SensorDescription() has been fixed to accept the sensor name (GitHub Issue #2)
• Parameters for ObservingConditions.TimeSinceLastUpdate() and ObservingConditions.SensorDescription() have been corrected to SensorName.
