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

==============
Changes to ACE
==============

. When using the Embarcadero C++ Builder bcc64x compiler now bcc64x is
   used as linker instead of ld.lld

==============
Changes to TAO
==============

- TAO_IDL:
   - Support the following IDL v4 features (may not work everywhere in TAO):
     - Empty structs
     - `octet` and `wchar` union discriminators
     - Allow using `typedef`s of `int8` and `uint8` as union discriminators
     - Allow using empty parentheses in annotation applications to
       workaround syntax errors when an annotation with no arguments has to
       be followed by a complete scoped name:
         `@example_annotation() ::ex::ExampleType`
       This is a proposed solution to an IDL spec issue.
     - Reserve the `bitfield`, `bitmask`, and `bitset` keywords in IDL v4
       (these are not implemented yet)
   - Allow using `map` as an identifier in IDL v3 again
