GHC Trac Issues: #13875

- A bug in the :ghc-flag:`-XApplicativeDo` extension resulting in strict pattern
matches to be performed lazily (:ghc-ticket:`13875`) has been fixed. Note that
this means some programs which previously typechecked under ``ApplicativeDo``
will no longer as it is not possible to implement strict pattern matching
using only ``Applicative``.
- Old profiling flags ``-auto-all``, ``-auto``, and ``-caf-all`` are deprecated
and their usage provokes a compile-time warning.
