15 The following is a list of release highlights for the RMR
16 library. At one point in time the RMR repo also housed a
17 wrapper library with a separate version and release cycle.
18 This resulted in *leap frogging* versions for each package;
19 the RMR core library was assigned odd major numbers (e.g.
20 3.1.0). When the wrapper code was moved to a different repo
21 the need to leap frog versions ceased, and beginning with
22 version 4.0.0, the RMR versions should no longer skip.
25 2023 May 28; version 4.9.1
26 ------------------------------
28 Fixes IPv6 binding in RMR (RIC-985)

66 ------------------------------
68 Fixing memory leak in python support function (RIC-858).
69 New API added for debugging rmr rx queue (RIC-838).
73 2021 April 22; version 4.7.4
74 ----------------------------

77 analysis bugs. (RIC-777)
81 2021 April 19; version 4.7.3
82 ----------------------------
84 Correct flag check bug in route table functions (RIC-777).

104 ----------------------------
106 The route table collector thread will capture the current
107 "offering" from the Route Manager (table generator) if the
108 RMR_SEED_RT environment variable is set.
112 2021 March 10; version 4.6.1
113 ----------------------------
115 Corrected unit test "framework" to make manual testing
116 easier, and to add the ability to set the code optimisation
117 level via the CMake command line parameter OPT_LEVEL=n.
121 2021 February 22; Version 4.6.0
122 -------------------------------
124 Enhanced to use millisecond based timestamps when writing log
127 Enhanced to eliminate the reqirement that the file specified
128 by the RMR_VCTL_FILE environment variable exist when RMR is
129 initialised. RMR will correctly find this file if it is
130 created after initialisation. Further, if the environment
131 variable is not given, the user may create and populate
132 /tmp/rmr.v at any time and the contents of this file will be
133 used as if it were supplied via the environment variable.
134 This should make debugging in existing containers easier.
136 Enhanced to send an alarm manager when the user application
137 is not receiving messages fast enough. The original messages
138 written to the standard error are still generated. (RIC-204)

290 2020 July 9; version 4.1.3
291 --------------------------
293 Allow RTS messages to be sent before the arrival of the
294 initial route table. Calls to RTS (heart beat responses)
295 prior to the initial route table load could cause a crash if
296 a framework blindly assumes that RTS is valid. (RIC-589)
300 2020 June 22; version 4.1.2
301 ---------------------------
303 Fix typo in RIC Message header file.
305 Add document for message type constants and the scripts which

377 2020 April 21; version 4.0.0
378 ----------------------------
380 The NNG based libraries are no longer included in the RMR
381 packages. This is considered a breaking change as NNG will
382 not be supported by default. It is still possible to build
383 with RMR-NNG libraries, but that is the exception. The API
384 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
385 means that the underlying transport mechanism is limited only
388 The rmr_rcv_specific() function has been deprecated as it was
389 necessary only for NNG and Nanomsg support. Its use should be
394 2020 April 20; version 3.8.2

442 2020 April 9; version 3.7.1
443 ---------------------------
445 The max length restriction for receiving messages when using
446 SI95 has been removed. The length supplied during
447 initialisation is used as the "normal maximum" and default
448 buffer allocation size, but messages arriving which are
449 larger are accepted. (RIC-309)
453 2020 April 7; version 3.7.0
454 ---------------------------
456 The health check support programme was renamed to rmr_probe

715 New message type constants added to support A1.
719 2019 November 4; version 1.11.0
720 -------------------------------
722 Version bump to move away from the 1.10.* to distinguish

727 2019 November 7; version 1.12.0
728 -------------------------------
730 Version cut to support continued development for next release
731 preserving the 1.11.* versions for release 1 (Amber) and

773 during jenkins verification testing at command and merge
775 Handle the NNG connection shutdown status which may now be
776 generated when a connection throug a proxy is reset.
780 2019 September 25; version 1.8.2
781 --------------------------------
783 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
787 2019 September 19; version 1.8.1
788 --------------------------------
790 Correct missing constant for wrappers.
794 2019 September 19; version 1.8.0
795 --------------------------------
797 New message types added:
798 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
802 2019 September 17; version 1.7.0
803 --------------------------------
805 Initial connection mode now defaults to asynchronous. Set
806 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
807 invoked to revert to synchronous first TCP connections.
808 (Recovery connection attempts have always been asynchronous).
812 2019 September 3; version 1.6.0
813 -------------------------------
815 Fix bug in the rmr_rts_msg() function. If a return to sender
816 message failed, the source IP address was not correctly
817 adjusted and could cause the message to be "reflected" back
818 to the sender on a retry.
820 Added the ability to set the source "ID" via an environment
821 var (RMR_SRC_ID). When present in the environment, the string
822 will be placed in to the message header as the source and
823 thus be used by an application calling rmr_rts_smg() to
824 return a response to the sender. If this environment variable
825 is not present, the host name (original behaviour) is used.
829 2019 August 26; version 1.4.0
830 -----------------------------
832 New message types were added.
836 2019 August 16; version 1.3.0
837 -----------------------------
839 New mesage types added.
843 2019 August 13; version 1.2.0 (API change, non-breaking)
844 --------------------------------------------------------
846 The function rmr_get_xact() was added to proide a convenient
847 way to extract the transaction field from a message.
851 2019 August 8; version 1.1.0 (API change)
852 -----------------------------------------
854 This change should be backward compatable/non-breaking A new
855 field has been added to the message buffer (rmr_mbuf_t). This
856 field (tp_state) is used to communicate the errno value that
857 the transport mechanism might set during send and/or receive
858 operations. C programmes should continue to use errno
859 directly, but in some environments wrappers may not be able
860 to access errno and this provides the value to them. See the
861 rmr_alloc_msg manual page for more details.
865 2019 August 6; version 1.0.45 (build changes)
866 ---------------------------------------------
868 Support for the Nanomsg transport library has been dropped.
869 The library librmr.* will no longer be included in packages.
871 Packages will install RMR libraries into the system preferred
872 target directory. On some systems this is /usr/local/lib
873 and on others it is /usr/local/lib64. The diretory is
874 determined by the sytem on which the package is built and
875 NOT by the system installing the package, so it's possible
876 that the RMR libraries end up in a strange location if the
877 .deb or .rpm file was generated on a Linux flavour that
878 has a different preference than the one where the package
883 2019 August 6; version 1.0.44 (API change)
884 ------------------------------------------
886 Added a new message type constant.
890 2019 July 15; Version 1.0.39 (bug fix)
891 --------------------------------------
893 Prevent unnecessary usleep in retry loop.
897 2019 July 12; Version 1.0.38 (API change)
898 -----------------------------------------
900 Added new message types to RIC_message_types.h.
904 2019 July 11; Version 1.0.37
905 ----------------------------

910 (see rmr_trace_ref.3 manual page in dev package).
914 2020 April 8; Version n/a
915 -------------------------
917 RMR Python moved to Python Xapp Framework
