How can I see the PlatformIO documentation for previus versions, specifically v5.2.5? There are configuration settings such as “test_transport” that are no longer available in v6.0.x, but I need to see what these settings used to do.
We have not yet done the work required to bring our projects and CI pipelines forward to v6.0.x, so are trying to keep them working on v5.2.5 until we do. The latest problem is the native platform update to v1.2.1 which is incompatible with PlatformIO v5.2.5. Although native @ 1.2.0 still installs OK on v5.2.5, “test_transport = none” now fails with;
Error: Unknown Unit Test transport `None`. Please check a documentation how to create an own 'Test Transport':
