.. _release-9-8-1:
Version 9.8.1
=============
Language
~~~~~~~~
Compiler
~~~~~~~~
- Added a new warning :ghc-flag:`-Wterm-variable-capture` that helps to make code compatible with
the future extension ``RequiredTypeArguments``.
- Rewrite rules now support a limited form of higher order matching when a
pattern variable is applied to distinct locally bound variables. For example: ::
forall f. foo (\x -> f x)
Now matches: ::
foo (\x -> x*2 + x)
GHCi
~~~~
Runtime system
~~~~~~~~~~~~~~
- On POSIX systems that support timerfd, RTS shutdown no longer has to wait for
the next RTS 'tick' to occur before continuing the shutdown process. See #22692.
