Valgrind Software Quick Start Manual page 241

* exp-Omega, an experimental instantaneous leak-detecting tool, is no
longer built by default, although the code remains in the repository
and the tarball. This is due to three factors: a perceived lack of
users, a lack of maintenance, and concerns that it may not be
possible to achieve reliable operation using the existing design.
* As usual, support for the latest Linux distros and toolchain
components has been added. It should work well on Fedora Core 10,
OpenSUSE 11.1 and Ubuntu 8.10. gcc-4.4 (in its current pre-release
state) is supported, as is glibc-2.9. The C++ demangler has been
updated so as to work well with C++ compiled by even the most recent
g++'s.
* You can now use frame-level wildcards in suppressions. This was a
frequently-requested enhancement. A line "..." in a suppression now
matches zero or more frames. This makes it easier to write
suppressions which are precise yet insensitive to changes in
inlining behaviour.
* 3.4.0 adds support on x86/amd64 for the SSSE3 instruction set.
* Very basic support for IBM Power6 has been added (64-bit processes only).
* Valgrind is now cross-compilable. For example, it is possible to
cross compile Valgrind on an x86/amd64-linux host, so that it runs
on a ppc32/64-linux target.
* You can set the main thread's stack size at startup using the
new --main-stacksize= flag (subject of course to ulimit settings).
This is useful for running apps that need a lot of stack space.
* The limitation that you can't use --trace-children=yes together
with --db-attach=yes has been removed.
* The following bugs have been fixed. 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 (http://bugs.kde.org/enter_valgrind_bug.cgi) rather than
mailing the developers (or mailing lists) directly.
