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 2021 December 2; version 4.8.0
26 ------------------------------
28 Fixing memory leak in python support function (RIC-858).
29 New API added for debugging rmr rx queue (RIC-838).
33 2021 April 22; version 4.7.4
34 ----------------------------
36 Beef up unit testing in SI package and fix a few static
37 analysis bugs. (RIC-777)
41 2021 April 19; version 4.7.3
42 ----------------------------
44 Correct flag check bug in route table functions (RIC-777).
48 2021 April 9; version 4.7.2
49 ---------------------------

52 is not applied before a full route table is received.
56 2021 April 2; version 4.7.1
57 ---------------------------
59 Correct issues found during static code analysis.
63 2021 March 31; version 4.7.0
64 ----------------------------
66 The route table collector thread will capture the current
67 "offering" from the Route Manager (table generator) if the
68 RMR_SEED_RT environment variable is set.
72 2021 March 10; version 4.6.1
73 ----------------------------
75 Corrected unit test "framework" to make manual testing
76 easier, and to add the ability to set the code optimisation
77 level via the CMake command line parameter OPT_LEVEL=n.
81 2021 February 22; Version 4.6.0
82 -------------------------------
84 Enhanced to use millisecond based timestamps when writing log
87 Enhanced to eliminate the reqirement that the file specified
88 by the RMR_VCTL_FILE environment variable exist when RMR is
89 initialised. RMR will correctly find this file if it is
90 created after initialisation. Further, if the environment
91 variable is not given, the user may create and populate
92 /tmp/rmr.v at any time and the contents of this file will be
93 used as if it were supplied via the environment variable.
94 This should make debugging in existing containers easier.
96 Enhanced to send an alarm manager when the user application
97 is not receiving messages fast enough. The original messages
98 written to the standard error are still generated. (RIC-204)
102 2021 January 21; Version 4.5.2

250 2020 July 9; version 4.1.3
251 --------------------------
253 Allow RTS messages to be sent before the arrival of the
254 initial route table. Calls to RTS (heart beat responses)
255 prior to the initial route table load could cause a crash if
256 a framework blindly assumes that RTS is valid. (RIC-589)
260 2020 June 22; version 4.1.2
261 ---------------------------
263 Fix typo in RIC Message header file.
265 Add document for message type constants and the scripts which
270 2020 June 22; version 4.1.1

337 2020 April 21; version 4.0.0
338 ----------------------------
340 The NNG based libraries are no longer included in the RMR
341 packages. This is considered a breaking change as NNG will
342 not be supported by default. It is still possible to build
343 with RMR-NNG libraries, but that is the exception. The API
344 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
345 means that the underlying transport mechanism is limited only
348 The rmr_rcv_specific() function has been deprecated as it was
349 necessary only for NNG and Nanomsg support. Its use should be
354 2020 April 20; version 3.8.2

402 2020 April 9; version 3.7.1
403 ---------------------------
405 The max length restriction for receiving messages when using
406 SI95 has been removed. The length supplied during
407 initialisation is used as the "normal maximum" and default
408 buffer allocation size, but messages arriving which are
409 larger are accepted. (RIC-309)
413 2020 April 7; version 3.7.0
414 ---------------------------
416 The health check support programme was renamed to rmr_probe

668 payload was not always copied.
672 2019 November 13; version 1.12.1
673 --------------------------------
675 New message type constants added to support A1.
679 2019 November 4; version 1.11.0
680 -------------------------------
682 Version bump to move away from the 1.10.* to distinguish
683 between release A and the trial.
687 2019 November 7; version 1.12.0
688 -------------------------------
690 Version cut to support continued development for next release
691 preserving the 1.11.* versions for release 1 (Amber) and

740 2019 September 25; version 1.8.2
741 --------------------------------
743 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
747 2019 September 19; version 1.8.1
748 --------------------------------
750 Correct missing constant for wrappers.
754 2019 September 19; version 1.8.0
755 --------------------------------
757 New message types added:
758 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
762 2019 September 17; version 1.7.0
763 --------------------------------
765 Initial connection mode now defaults to asynchronous. Set
766 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
767 invoked to revert to synchronous first TCP connections.
768 (Recovery connection attempts have always been asynchronous).
772 2019 September 3; version 1.6.0
773 -------------------------------
775 Fix bug in the rmr_rts_msg() function. If a return to sender
776 message failed, the source IP address was not correctly
777 adjusted and could cause the message to be "reflected" back
778 to the sender on a retry.
780 Added the ability to set the source "ID" via an environment
781 var (RMR_SRC_ID). When present in the environment, the string
782 will be placed in to the message header as the source and
783 thus be used by an application calling rmr_rts_smg() to
784 return a response to the sender. If this environment variable
785 is not present, the host name (original behaviour) is used.
789 2019 August 26; version 1.4.0
790 -----------------------------
792 New message types were added.
796 2019 August 16; version 1.3.0
797 -----------------------------
799 New mesage types added.
803 2019 August 13; version 1.2.0 (API change, non-breaking)
804 --------------------------------------------------------
806 The function rmr_get_xact() was added to proide a convenient
807 way to extract the transaction field from a message.
811 2019 August 8; version 1.1.0 (API change)
812 -----------------------------------------
814 This change should be backward compatable/non-breaking A new
815 field has been added to the message buffer (rmr_mbuf_t). This
816 field (tp_state) is used to communicate the errno value that
817 the transport mechanism might set during send and/or receive
818 operations. C programmes should continue to use errno
819 directly, but in some environments wrappers may not be able
820 to access errno and this provides the value to them. See the
821 rmr_alloc_msg manual page for more details.
825 2019 August 6; version 1.0.45 (build changes)
826 ---------------------------------------------
828 Support for the Nanomsg transport library has been dropped.
829 The library librmr.* will no longer be included in packages.
831 Packages will install RMR libraries into the system preferred
832 target directory. On some systems this is /usr/local/lib
833 and on others it is /usr/local/lib64. The diretory is
834 determined by the sytem on which the package is built and
835 NOT by the system installing the package, so it's possible
836 that the RMR libraries end up in a strange location if the
837 .deb or .rpm file was generated on a Linux flavour that
838 has a different preference than the one where the package
843 2019 August 6; version 1.0.44 (API change)
844 ------------------------------------------
846 Added a new message type constant.
850 2019 July 15; Version 1.0.39 (bug fix)
851 --------------------------------------
853 Prevent unnecessary usleep in retry loop.
857 2019 July 12; Version 1.0.38 (API change)
858 -----------------------------------------
860 Added new message types to RIC_message_types.h.
864 2019 July 11; Version 1.0.37
865 ----------------------------
868 librmr and librmr_nng
869 - Add message buffer API function rmr_trace_ref()
870 (see rmr_trace_ref.3 manual page in dev package).
874 2020 April 8; Version n/a
875 -------------------------
877 RMR Python moved to Python Xapp Framework
