2.  What is new in 3.7.0

2.1  OpenSIPS script

• The return statement may now also take variables as 1st argument, not just constants.

2.2  OpenSIPS Core

• NEW Multi-Lock Memory Allocator, built into standard packages and selectable at runtime, dubbed: F_PARALLEL_MALLOC.
• NEW SDP real-time editing variables: $sdp, $sdp.line, $sdp.stream, $sdp.session and $sdp.stream.idx.
  • before any of the new $sdp variables are used, all existing SDP lump changes are applied
  • before any SDP-related lump changes are done (e.g. rtpproxy, rtpengine, etc.), if there are any $sdp variable changes, the new SDP is re-generated and passed to the respective code
• Added the $return variable which can be used to retrieved the return value of the previously executed route.
• New {s.date2unix} transformation, for easily parsing and/or validating the RFC-3261 format of the SIP "Date" header
• A new class of pseudo-variables had been added, $challenge.* that allows you to read information present in the WWW-Authorize or Proxy-Authorize headers.
• new option to set the TOS per socket (versus the global option)
• the $socket_out variable has been enhanced with the forced subfield, which returns NULL in case no socket has been explicitly enforced/set.
• new set of $msg.branch.XXXXX variables, to operate over the message branches - add new branches, change all the fields of an existing branch, add custom flags and attributes to the flags, support of powerful indexing. See a comprehensive description in this blog post.
• new core function append_msg_branch(), similar to old append_branch() (which to become deprecated), but without inheriting any properties from the RURI branch.
• added "sub-domain" matching support for SIP domain aliasing, in the SIP socket definition and in the SIP aliases definition.
• the auto scaling engine is enhanced with status/report support; each auto-scaling group has its own status/report identifier where it logs all ops like forking or ripping processes in the group.

2.3  [NEW] CACHEDB_DYNAMODB module

• The new cachedb_dynamodb module has been added to provide integration with Amazon's DynamoDB database.

• added support for libcouchbase API v3. Also fully dropped the older v2.3 support.

2.16  CACHEDB_REDIS module

• added support for column-oriented cacheDB operations, using Redis Stack Server features such as RedisJSON and RediSearch. This now allows cachedb_redis to be used as backend for the user location (usrloc) module, in both Federation and Full-Sharing modes of operation. The Redis server-side JSON support is auto-detected, with appropriate startup logs being displayed (zero-configuration).

• new set_dlg_profile and unset_dlg_profile MI functions were added, with the same functionality as the script functions.

2.21  DISPATCHER module

• NEW ping_sock= configuration option for the partition module parameter, for customizing the ping origination socket

2.23  DNS_CACHE module

• new min_ttl modparam to control the minimum TTL value for a caching.

2.24  EVENT_FLATSTORE module

• The files generated by the event_flatstore module can be automatically rotated based on different criterias: the rotate_period, rotate_count and rotate_size can be used to indicate whether to rotate a file based on its timestamp, the number of lines/entries, or the size of the file
• A new escape_delimiter module parameter has been added that can be optionally used to escape the values
• The new suffix module parameter can be used to parameterize the files's name - this is useful in combination with the rotation, to define a patter of the resulted files.
• The new suffix module parameter can be used to parameterize the files's name - this is useful in combination with the rotation, to define a patter of the resulted files.
• A new E_FLATSTORE_ROTATION has been added that is being raised when a file's rotation is being triggered.

• New json_merge function to merge two json objects.

2.28  MEDIA_EXCHANGE module

• All the media_fork_*() functions had been enhanced with a new instance parameter, that allows you to start multiple media fork sessions and control them based on the instance.

2.29  MQUEUE module

• A new parameter has been added to the mq_fetch MI command that can help you fetch multiple items from the queue at once.

2.30  PERMISSIONS module

• removed 128 subnets limitation (any number of subnets can be loaded from DB now)
• improved address lookup performance thanks to internal data structures rework (now using trie-like data structures in order to store & walk IP address bits)
• all MI input/output is fully-backwards compatible with previous versions

2.31  PROMETHEUS module

2.33  RATELIMIT module

• A new function was added, rl_values() that can be used to retrieve all the pipes' names available.
• [Performance] Pipe Replication: "zero pipes" are now broadcasted to the cluster a maximum of 3 times, to avoid sending redundant data

2.34  REGISTRAR module

• the attributes of a registered contact are read (during save()) from AVPs, but they are written back (at lookup() time) into the attributes of the message branch. The names of the AVP and of the branch attribute are the same, dictated by the attr_avp mod param.

2.35  RTP_RELAY module

• The module can call a set of routes when media/SDP events are triggered - this can be used to perform custom RTP relaying operations.

2.36  RTPEngine module

• Added async support for rtpengine_offer(), rtpengine_answer() and rtpengine_delete().
• The sock_var function parameter (to various RTPE functions) may now function as a IN/OUT parameter instead of just OUT. If the passed variable holds a value, then this value will be parsed and used as a known, explicit RTPEngine socket to run the command against.
• The rtpengine_stop_media() function can receive an extra parameter that returns the position of the last media file played.
• Added ping_enabled parameter that makes the module ping enabled nodes as well, if they are idle.
• The rtpengine_enable MI command has been enhanced to allow setting a node in probing mode.
• A new parameter named extra_failover_error has been added that allows you to failover to a new node in case of custom errors reported by RTPengine.
• The E_RTPENGINE_STATUS event contains a new set parameter which helps you differentiate between multiple events of the same socket in different sets.
• Added the rtpengine_pause_recording() function to pause recording sessions started from script.

2.37  RTPProxy module

• The rtporoxy_enable MI command has been enhanced to allow setting a node in probing mode.

2.38  SIPREC module

• Two new events have been added, E_SIPREC_START and E_SIPREC_STOP, that are being triggered when a SIPREC session is started and terminated/stopped.
• A new function, siprec_send_indialog() has been added to allow you send arbitrary requests to the SIPREC SRS.
• All the siprec modules script functions had been enhanced with an extra parameter, instance that allows you to start multiple, parallel recording sessions to different SRS servers.

• NEW sql_cache_dump() function -- allowing developers to fully dump a cached SQL table at opensips.cfg level

2.40  STIR_SHAKEN module

• Enhanced error reporting (several new SIP error reply messages now being returned, better describing the failure reason)

2.41  TM module

• new set of $tm.branch.XXXXX variables, to operate over the transaction branches - access to all the fields of an existing branch, read/write custom flags and attributes to the branch. The variables come with a powerful indexing support to allow inter-branch data access - basically this allows access to the fields of any branch of the transaction from the BRANCH/REPLY/FAILURE routes. See a comprehensive description in this blog post.
• new t_get_branch_idx_by_attr() function to search for the index of another branch of the current transaction based on the name (and value) of a branch attribute.
