6.10.2 is a bugfix release over 6.10.1. Many bugs in the compiler, libraries and build system have been fixed. However, most library APIs have not changed, so code that worked with 6.10.1 should continue to work with 6.10.2. The notable bug fixes are listed below.
Setting stdin to NoBuffering now works on Windows.
System.FilePath.dropTrailingPathSeparator "\\"
will now return "\\" rather than
"".
The compatibility Control.OldException functions
now catch new-style exceptions as DynExceptions.
It is now possible to create C finalizers which, unlike Haskell finalizers, are guaranteed to run.
There is now a +RTS -xm<address> flag,
which tells GHC where to try to allocate memory.
There is now a +RTS --machine-readable flag.
Currently it only affects the +RTS -t output.
There are now more fields printed by the
+RTS --info flag.
ghc-pkg will now complain if told to use a
package.conf that doesn't exist.
ghc-pkg check now looks for missing files
(including .hi files), and reports all packages that are
transitively broken.
The TypeFamilies extension now implies the
RelaxedPolyRec extension.
