See interactive debugging for further detail. (#2972)

• trio.testing.RaisesGroup can now catch an unwrapped exception with unwrapped=True. This means that the behaviour of except* can be fully replicated in combination with flatten_subgroups=True (formerly strict=False). (#2989)

Bugfixes

• Fixed a bug where trio.testing.RaisesGroup(..., strict=False) would check the number of exceptions in the raised ExceptionGroup before flattening subgroups, leading to incorrectly failed matches.
  It now properly supports end ($) regex markers in the match message, by no longer including " (x sub-exceptions)" in the string it matches against. (#2989)

Deprecations and removals

• Deprecated strict parameter from trio.testing.RaisesGroup, previous functionality of strict=False is now in flatten_subgroups=True. (#2989)
