[Valgrind-announce] Valgrind-3.8.1 is available

[Julian S. <js...@ac...>]

We are pleased to announce a new release of Valgrind, version 3.8.1,
available from http://www.valgrind.org.  See the attached release
notes for details.

Happy (and productive) debugging and profiling,

-- The Valgrind Developers


Release 3.8.1 (19 September 2012)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.8.1 is a bug fix release.  It fixes some assertion failures in 3.8.0
that occur moderately frequently in real use cases, adds support for
some missing instructions on ARM, and fixes a deadlock condition on
MacOSX.  If you package or deliver 3.8.0 for others to use, you might
want to consider upgrading to 3.8.1 instead.

The following bugs have been fixed or resolved.  Note that "n-i-bz"
stands for "not in bugzilla" -- that is, a bug that was reported to us
but never got a bugzilla entry.  We encourage you to file bugs in
bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.

where XXXXXX is the bug number as listed below.
