====== Changelog of SSG BETA-version ======
{{indexmenu_n>3}}

====Changes in version 14.0 BETA1====

  - [BRAS] Support for L2TP termination
  - [BRAS] Support for DHCP-Dual
  - [DPI]  Migration to DPDK 24.11, support for new NICs (Intel E830 200G, Intel E630, Napatech SmartNIC)
  - [CLI] Added support for ''subs_id'' in commands: ''dhcp show'', ''dhcp reauth'', ''dhcp6 show'', ''dhcp6 reauth'', and ''dhcp disconnect''

====Changes in version 14.0 BETA2====

  - [DPI] New protocols added: AGORA_STREAMS(49314), AZAR_CALL(49315), WECHAT_CALL(49316), TEAMS_CALL(49317). [[dpi:dpi_options:protocols]]
  - [DPI] Improved support for LINE_CALL, VYKE_CALL protocols. [[dpi:dpi_options:protocols]]
  - [DPI] Fixed smartdrop behavior
  - [DPI] Added validation for complex protocols. [[dpi:dpi_options:protocols]]
  - [DPDK] Increased the maximum number of dispatchers to 32
  - [IPFIX/Netflow] Added the ability to change IPFIX/Netflow parameters without restarting fastDPI. A new config parameter ''ipfix_reserved'' has been added to reserve memory for enabling/changing IPFIX/Netflow parameters. If IPFIX/Netflow parameters are set in the configuration file, memory reservation for IPFIX/Netflow is automatically enabled and parameters/new exporter types can be changed without restarting fastDPI.
  - [FastRadius] It is now possible to set both ''bind_ipv6_address'' and ''bind_ipv6_subnet''. If the Framed-IPv6-Prefix has a /128 mask, it is not checked against the ''bind_ipv6_subnet'' restriction.
  - CLI command ''dev info'' now includes the name of the LAG that the port belongs to
  - [PCRF][PPP][Framed-pool] Added: DHCP option ''Client-Id'' now includes ''tunnel-IP'' as part of the subscriber ID. Format of DHCP option ''Client-Id'' with fastpcrf.conf option ''dhcp_client_id=1'' is as follows: <code>
     [conntype][subs_id][tunnel_ip]

     conntype = 1 (1 byte)
     subs_id  - 16 bytes
     tunnel_ip - 4 bytes</code> Tunnel IP is available in L2TP; for PPPoE, tunnel IP = 0.
  - [IPFIX] Message aggregation added for IPFIX streams: FullFlow/DNS/META/NAT
  - [IPFIX] Added parameter ''ipfix_mtu_limit'' to restrict maximum message size for IPFIX UDP packets
  - [IPFIX DNS] New elements added to IPFIX DNS: 224 (ipTotalLength) and 43823:3206 (DNS transaction id)
  - [VRRP] Fixed proper handling of the ''vrrp_enable'' option change
  - [BRAS][PPP] PPP session key is now compound: ''l2subs_id'' + ''tunnel-IP''. For PPPoE sessions, tunnel IP = 0. CLI commands that use ''subs_id'' as a key (''subs prop show'', ''l2tp show session'', ''l2tp term'', etc.) may now return multiple entries with the same ''l2subs_id''.

====Changes in version 14.0 BETA3====

  - [DPI] Added cloud protocols with identifiers 55296..58367
  - [IPFIX] Fixed IPFIX exporter reinitialization bugs
  - [BRAS][subs_grooming] Fixed potential crash due to race condition during fastDPI shutdown
  - [CLI] Added commands to display mempool properties and statistics<code>
    hal mempool props
    hal mempool stat</code>DPDK must be built with statistics collection enabled to display mempool stats
  - [BRAS][DHCP] Fixed crash when parsing Framed-Pool Renew response if it contains no DHCP options
  - [PCRF][Acct] Fixed: Interim-Update sending is now disabled when ''Acct-Interim-Interval = 0'' is explicitly set in the RADIUS response
  - [VASE_CLI] Created a unified CLI for managing DPI, BRAS, DHCP (KEA), ROUTER (BIRD) with support for authorization and command logging via TACACS (VEOS 8.x required)
  - [SNMP] Created a module for monitoring system components via SNMP


====Update instructions====
You can check the current installed version with the command below
<code bash>
yum info fastdpi
</code>

If you have CentOS 6.x or CentOS 8.x installed, then switch the repository once with the command:
<code bash>
sed -i -e '/^mirrorlist=http:\/\//d' -e 's/^# *baseurl=http:\/\/mirror.centos.org/baseurl=http:\/\/vault .centos.org/' /etc/yum.repos.d/CentOS-*.repo
</code>
and then update as usual.

To install the test version, you should issue the following command:
<code bash>
yum --enablerepo vasexperts-beta update fastdpi
</code>
 
Downgrade to 13.3:

<code bash>
yum downgrade fastdpi-13.3 fastpcrf-13.3 dpiutils-13.3 fastradius-13.3 
</code>

<note important>After an update or version change, a restart of the service is required.</note>
