<h3>RSRV uses EPICS_CAS_INTF_ADDR_LIST</h3>
<h3>CA server configuration changes</h3>
<p>RSRV now honors the EPICS_CAS_INTF_ADDR_LIST to bind to only
the provided list of network interface.
<p>RSRV now honors EPICS_CAS_INTF_ADDR_LIST and binds to only
the provided list of network interfaces.
Name searches (UDP and TCP) on other network interfaces are ignored.
For example on a computer with interfaces 10.5.1.1/24, 10.5.2.1/24, and 10.5.3.1/24,
setting "EPICS_CAS_INTF_ADDR_LIST='10.5.1.1 10.5.2.1'" will accept traffic
on the .1.1 and .2.1, but ignore from .3.1</p>
<p>RSRV now honors EPICS_CAS_IGNORE_ADDR_LIST and ignores
UDP messages received from addresses in this list.</p>
<p>Previously, CA servers (RSRV and PCAS) would build the beacon address list
using EPICS_CA_ADDR_LIST if EPICS_CAS_BEACON_ADDR_LIST was no set.
This is no longer done.

<h3>IPv4 multicast for name search and beacons</h3>
<p>libca and RSRV may now use IPv4 multicasting for UDP traffic (name search and beacons).
<p>libca, RSRV, and PCAS may now use IPv4 multicasting for UDP traffic (name search and beacons).
This is disabled by default.
To enable multicast address(s) must be listed in EPICS_CA_ADDR_LIST for clients
and EPICS_CAS_INTF_ADDR_LIST for servers (IOCs should set both).
For example: "EPICS_CAS_INTF_ADDR_LIST='0.0.0.0 224.0.2.9' EPICS_CA_ADDR_LIST=224.0.2.9".
For example: "EPICS_CAS_INTF_ADDR_LIST='224.0.2.9' EPICS_CA_ADDR_LIST=224.0.2.9".
</p>
<p>Please note that no IPv4 multicast address is officially assigned for Channel Access by IANA.
