devSymb</H3>
This has been drastically changed. Look at &lt;base>/src/dev/symbDev/README
for details.
<H3>
CA Client Library</H3>
Problems where 3.13.beta11 clients were unable to connect to 3.11 and receive the correct
native type have been fixed.
The CPU is now consumed more efficently by CA tasks waiting in select() under vxWorks.
The client lib now detects an IOC reboot when that reboot is faster that EPICS_CA_CONN_TMO.
CA now runs better on systems without local interface query capabilities (currently
only cygwin32).
<H3>
C++ Channel Access Server - CAS</H3>
The constructor for class casPV no longer requires a reference to the
server. For backward compatibility a reference to the server may still be
supplied, but it will not be used. The C++ Portable Channel Access Server Library now builds
on VMS. A really bad bug was fixed in the example directory server when clients use PV names
with ".xxxx" (a field name) in them.
<H3>
Global Data Descriptor Class - GDD (only used by the C++ CA server)</H3>
A bug occurring when the primitive type was changed to/from aitSting and the
constructor/destructor member functions for class aitString were not run has
been fixed.
A bug occurring when class GDD changed the bounds on the destination GDD has
been fixed.
A smart pointer class for GDD was added. This class automatically
maintains the GDD's reference count so that the GDD will not be deleted
until the last smart pointer class pointing to it is deleted. Moving this
responsibility to a class will greatly reduce the probability of making
a mistake in application code.
<H3>
WIN32 (PC) Port of EPICS</H3>
Winsock II is now required. This allows CA to properly execute EPICS_CA_ADDR_LIST=YES.
Windows NT 4.0 comes with Winsock II. A properly functioning
Winsock II for Windows 95 can be obtained form http://www.microsoft.com/windows95/info/ws2.htm.
Beware of buggy versions of Win95 Winsock II that are sometimes installed by 3rd party products.
A static (no EPICS DLLs) build of EPICS on WIN32 is now supported. The EPICS CA repeater is now
automatically started under WIN32 if it isnt running. At Ken Evans' request GUI programs will this release
_not_ allocate a console for messages from EPICS libraries unless base is compiled with
host optimisation turned off (HOST_OPT=NO). If you would like to see messages from EPICS base
libraries when using an optimised build, then start GUI programs from a DOS window.
<H3>
EPICS Environment Variables that Include Host IP Addresses</H3>
It is now possible to use DNS host names in addition to dotted IP addresses in EPICS environment
variables. All operating systems that have a DNS client implementation
should allow this. Currently only vxWorks does not, and so if you would like to use real host names
instead of dotted IP addresses on vxWorks you must use the "hostAdd()" function to add host
name / IP address pairs from your system start-up script. For Example:
hostAdd ("mercury_dirigible","100.20.30.40")
putenv ("EPICS_IOC_LOG_INET=mercury_dirigible")
<H3>
GCC 2.8</H3>
The host portions of EPICS now build correctly with GCC 2.8
<H2>
Changes between beta4 and beta11</H2>
