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

. Fix ACE_Vector::end(), which now correctly
  represents the end of the elements of the vector
  instead of the end of the base array.

Changes to TAO

. Enhanced the ImR to better handle a huge number
  of servers which use the ImR heavily and each of
  them does a frequent shutdown/start cycle

. The TAO_IDL frontend library now parses all IDL4
  annotation-related syntax: using and defining annotations.
  Use the tao_idl command-line options --idl-version and
  --unknown-annotations to control annotation parsing.
  Documentation on this feature is located in

. TAO_IDL now will return an error status code when
  passing an invalid command line argument.
  Backends will have to support this behavior
  explicitly, see TAO/TAO_IDL/include/idl_defines.h
  for details.
  TAO_IDL also accepts new options such as -h,
  --help, --version, and --syntax-only, the latter
  of which won't generate any files, just check
  syntax of the IDL file(s).
  See tao_idl -h for details.

. When using IDL_Files in MPC, generated files will
  now be placed in the current directory by default,
  instead of the directory of the IDL file.
    idlflags += -o <IDL_FILE_DIR>
    gendir = <IDL_FILE_DIR>
  to output generated files to where the IDL file
