Previous Behavior: GGSN was supporting DNS for IPv4 PDP context only.
New Behavior: This feature will enhance the DNS support for IPv4/IPv6 PDP Context in GGSN. In this feature MS
may request for DNS server IPv4 or IPv6 addresses using the Protocol Configurations Options IE (as a container or as a
part of IPCP protocol configuration request), in PDP Context Activation procedure, for PDP Type IPv4, IPv6 or IPv4v6.
In that case, the GGSN, may return the IP address of one or more DNS servers in the PCO IE, in the PDP Context
Activation Response message. The DNS address(es) shall be coded in the PCO as specified in 3GPP TS 24.008. This is
as per the CR number 1344 for 3GPP TS 24.008.

Enhancement to Simultaneous 3GPP Tracing
Previous Behavior: Prior to 15.0, the simultaneous 3GPP trace limit was 30 sessions.
New Behavior: From 15.0 onward, the 3GPP tracing limit is enhanced to support simultaneous traces from 30 to 1000.
The generated trace files are forwarded to external trace collection entity at regular intervals through (S)FTP if ‘push’
mode is enabled. If the push mode is not used, the files are stored on the local hard drive and must be pulled off by the
TCE using FTP or SFTP.
