This page documents current deprecations and upcoming planned changes inside Catch2. The difference between these is that a deprecated feature will be removed, while a planned change to a feature means that the feature will behave differently, but will still be present. Obviously, either of these is a breaking change, and thus will not happen until at least the next major release.
The CMake/CTest integration using ParseAndAddCatchTests.cmake is deprecated,
as it can be replaced by Catch.cmake that provides the function
catch_discover_tests to get tests directly from a CMake target via the
command line interface instead of parsing C++ code with regular expressions.
