## EPICS Release 7.0.3.2
### \*_API macros in headers
Internally, the Com and ca libraries now express dllimport/export (Windows)
and symbol visibility (GCC) with individual macros (eg. LIBCOM_API)
instead of using epicsShare\*. This change may effect user code which uses
epicsShare\* macros without explicitly including the shareLib.h header.
Such code should be changed to include shareLib.h directly.
A new helper script makeAPIheader.pl and rules to generate \*API.h headers
has been added. Run 'makeAPIheader.pl -h' for application information.
### IOCsh usage messages
`help <cmd>` now prints a descriptive usage message
