By default, GHC - provides access to the <literal>base</literal> package, - which includes the Haskell 2010 libraries, albeit with a few - minor differences. For those who want to write strictly - standards-conforming code we also provide - the <literal>haskell2010</literal> package which provides - the precise APIs specified by Haskell 2010, but because the - module names in this package overlap with those in - the <literal>base</literal> package it is not possible to - use both <literal>haskell2010</literal> - and <literal>base</literal> at the same time (this also - applies to the <literal>array</literal> package). Hence to use - the Haskell 2010 libraries you should hide - the <literal>base</literal> and <literal>array</literal> - packages, for example with GHCi: -<screen> -$ ghci -package haskell2010 -hide-package base -hide-package array -</screen> - If you are using Cabal it isn't necessary to - hide <literal>base</literal> and <literal>array</literal> - explicitly, just don't include them in your <literal>build-depends</literal>. - </para> - </listitem> - - <listitem> - <para> - On POSIX platforms, there is a new I/O manager based on - epoll/kqueue/poll, which allows multithreaded I/O code to - scale to a much larger number (100k+) of threads. - </para> - </listitem> - - <listitem> - <para> - GHC now includes an LLVM code generator.
