Hi all,

Once again, thanks to the efforts of many developers, testers, and
users, we are pleased to announce the micro release
of ACE 6.3.4 and TAO 2.3.4 which is available from the usual
download location at:


under the heading "Latest Micro Release Kit".

Or from the github release page at:


The doxygen documentation for this release is also available.  In
addition to the packages combined of sources and generate makefiles,
this release provides source-only packages for developers who use MPC to
generate their own makefiles.

We encourage you to download the new release, use it with your
applications, and let us know if you encounter any problems. Please use the:


so that we have the proper version/platform/compiler/options you're
using to report problems. We also request that you take a look at:


for the status of various ongoing projects at the DOC group of
Vanderbilt to move ACE and TAO forward.  Overviews of our recent
progress and upcoming plans are available at:


The overall success rates for the test results gathered from all our
daily builds is 98% for the ACE tests and 98% for the TAO tests.

Please see:


for a summary of these tests.  As always, we appreciate your help in
resolving any remaining problems. Please see:

The following is a list of key changes since the last major release.
Please refer to the corresponding ChangeLog files, NEWS files, or
Bugzilla entries for more details on the problem and the nature of fixes

Changes to ACE

. ACE_SSL_Context::set_mode() can no longer be used to select a specific
  SSL/TLS protocol version, use ACE_SSL_Context::filter_versions() for
  that. This follows general advice by the OpenSSL project to go through
  SSL_CTX_set_options() to limit the list of protocols available. The
  purpose of ACE_SSL_Context::set_mode() is now limited to explicitly
  restricting behaviour to client or server (defaults to both).
. Improve Oracle Studio support
. CIAO and DAnCE are forked to their own github repositories
  and are not part anymore of the ACE+TAO release packages
. Fixed several Coverity reported issues
. Added ACE configuration for FACE safety profiles (see config-
  face-safety.h). FACE, or Future Airborne Capability Environment
  http://www.opengroup.org/face, specifies a restricted subset of OS
  functions and rules for controlling dynamic memory allocation.  When
  built in this configuration on a platform that supports it, ACE
  conforms to the FACE requirements.
. ACE uses new netdb.h functions (getaddrinfo/getnameinfo) if they are
  available, in place of deprecated functions (gethostbyname/addr).

Changes to TAO

. ImR enhancement - Added a "force remove" option to the Implementation
  repository that will remove a server entry from the ImR Locator
  repository and kill any running instance with a single command.
. ImR enhancement - Fix to allow very large ( > 4K ) command line.
. ImR enhancement - Enhance the coordination between the Locator and
  the Activator to tolerate running on heavily loaded systems, in
  particular when a server process is slow to shut down, and a new
  server is started before the shutdown is complete
. LogWalker utility improvements for handling truncated GIOP buffer
  dumps, added tracking thread first/last contact times.
. Fault-Tolerance improvement - Optimize performance on NFS mounted
  filesystems. First a deadlock is resolved. Second, use of writer
  locks is minimized to only when writing is necessary. Third, NFS
  occasionally causes transient EBADF errors on access, so
  file access that results in a bad file error is retried before the
  error is reported to the application.
