Functional changes:

• Dropped support for Python 3.8
• Added detect command for detecting connected CircuitPython boards (both CIRCUITPY and bootloader mode)
• Added optional timeout argument to install and update commands
• Improved error messages when things go wrong when downloading UF2s
• Updated requirements (both required and development)

Development changes:

• Fixed minor issues in Makefile commands
• Fixed CI issue where Windows tests were not fully cleaned up

• Added the cache latest command for caching the latest firmware version for a given board
• Added the ability to specify only perform only minor or patches updates when using the update command
• Fixed an issue with the version regex when querying versions using the query versions command
• Added the ability to use regex for the cache clear command
• Fixed an issue where the CI would fail due to GitHub rate limiting in the tests
• Changed the CI to test all currently supported versions of Python on Ubuntu, with a single Windows and MacOS runner each for the oldest supported version of Python
• Documentation updated for new commands and functionality

• Added update command, which is much like a shortcut for install for the latest CircuitPython version
• Added current command, which helps in identifying the board ID and CircuitPython version of a connected board
• Updated the API to more closely match circup, including update references of "board" to "board-id"
• Added documentation to ReadTheDocs
• Reworked the backend so that it is easier to work with in Python
• Regex can now be used to further limit the board list returned by what is now circfirm query board-ids

• Added the update command, which installs the latest release or pre-release version to the connected board
• Added the current command, which retrieves firmware and board information from the connected board
• install command now has its own file like the other commands
• Testing code refactored to improve test setup and helper functionalities

• Added circfirm query, which allows for query board names, versions for a given board, and specifically the latest version for a given board.
• Added circfirm config, which allows for setting configuration settings. Currently, the only two available are setting a GitHub token for use with circfirm query and silencing supporting text output for commands where scripting may be desirable.
• Fixed an issue where circfirm cache clear --version matched versions too greedily.

• Fixed issue where circfirm folder was being created in the current working directory
• Added a simple about command
• Added better user feedback in terminal, which should help during longer than expected UF2 downloads. Thanks @dhalbert for the suggestion!
• Added an additional project URL in pyproject.toml
• Improve the testing process by ensuring make test cleans up testing artifacts even if the test fails
• Makefile now includes make test-prep, make test-run, and make test-clean commands, which are utilized by the CI piecewise to detect failures in tests

• Fixed projects URLs in pyproject.toml
• Updated trove classifiers in pyproject.toml

Fixed an issue with detecting the board during parts of the install sequence.

• Allows boards with dashes in the name to be used with the CLI
• Now either reads the board name from the drive when in CIRCUITPY mode, or --board can be used when in bootloader mode
• Uses a regex to parse the board name

Fixed an issue with parsing pre-release versions that have been downloaded.
