Version 10.3.0 is done!
The headline feature in this release is being able to swap the Python test runner to be pytest instead of unittest (via the testrunner property under [python] in .plzconfig). Unittest tests have also been optimised a bit for faster rebuilding using some of the same mechanisms.
Other notable features include cgo_library rules accepting a pkg_config argument to determine appropriate compiler flags for dependencies, and the ability to opt individual go_library rules out of coverage instrumentation.
See https://github.com/thought-machine/please/releases/tag/v10.3.0 for notes & downloads. This is now the default version for new installs, and plz update will automatically update if your repository isn't pinned to a version.
Thanks to contributors, and to the bugs & suggestions for these features!
