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 April 19; version 4.7.3
26 ----------------------------
28 Correct flag check bug in route table functions (RIC-777).
32 2021 April 9; version 4.7.2
33 ---------------------------
35 Ensure that route table update received from route generator
36 is not applied before a full route table is received.
40 2021 April 2; version 4.7.1
41 ---------------------------
43 Correct issues found during static code analysis.
47 2021 March 31; version 4.7.0
48 ----------------------------
50 The route table collector thread will capture the current
51 "offering" from the Route Manager (table generator) if the
52 RMR_SEED_RT environment variable is set.
56 2021 March 10; version 4.6.1
57 ----------------------------
59 Corrected unit test "framework" to make manual testing
60 easier, and to add the ability to set the code optimisation
61 level via the CMake command line parameter OPT_LEVEL=n.
65 2021 February 22; Version 4.6.0
66 -------------------------------
68 Enhanced to use millisecond based timestamps when writing log
71 Enhanced to eliminate the reqirement that the file specified
72 by the RMR_VCTL_FILE environment variable exist when RMR is
73 initialised. RMR will correctly find this file if it is
74 created after initialisation. Further, if the environment
75 variable is not given, the user may create and populate
76 /tmp/rmr.v at any time and the contents of this file will be
77 used as if it were supplied via the environment variable.
78 This should make debugging in existing containers easier.
80 Enhanced to send an alarm manager when the user application
81 is not receiving messages fast enough. The original messages
82 written to the standard error are still generated. (RIC-204)
86 2021 January 21; Version 4.5.2
87 ------------------------------

234 2020 July 9; version 4.1.3
235 --------------------------
237 Allow RTS messages to be sent before the arrival of the
238 initial route table. Calls to RTS (heart beat responses)
239 prior to the initial route table load could cause a crash if
240 a framework blindly assumes that RTS is valid. (RIC-589)
244 2020 June 22; version 4.1.2
245 ---------------------------
247 Fix typo in RIC Message header file.
249 Add document for message type constants and the scripts which
254 2020 June 22; version 4.1.1

266 2020 June 18; version 4.1.0
267 ---------------------------
269 Bump version minor to move away from 4.0.* which will bump
270 for any patches applied back to bronze.
272 Add magic C++ goo to symtab header file allowing C++ xAPPs to

321 2020 April 21; version 4.0.0
322 ----------------------------
324 The NNG based libraries are no longer included in the RMR
325 packages. This is considered a breaking change as NNG will
326 not be supported by default. It is still possible to build
327 with RMR-NNG libraries, but that is the exception. The API
328 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
329 means that the underlying transport mechanism is limited only
332 The rmr_rcv_specific() function has been deprecated as it was
333 necessary only for NNG and Nanomsg support. Its use should be
338 2020 April 20; version 3.8.2

386 2020 April 9; version 3.7.1
387 ---------------------------
389 The max length restriction for receiving messages when using
390 SI95 has been removed. The length supplied during
391 initialisation is used as the "normal maximum" and default
392 buffer allocation size, but messages arriving which are
393 larger are accepted. (RIC-309)
397 2020 April 7; version 3.7.0
398 ---------------------------
400 The health check support programme was renamed to rmr_probe
405 2020 April 6; version 3.6.6
406 ---------------------------
408 Correct bug in SI95 address conversion module (RIC-327)
409 Correct bug in SI initialisation module

652 payload was not always copied.
656 2019 November 13; version 1.12.1
657 --------------------------------
659 New message type constants added to support A1.
663 2019 November 4; version 1.11.0
664 -------------------------------
666 Version bump to move away from the 1.10.* to distinguish
667 between release A and the trial.
671 2019 November 7; version 1.12.0
672 -------------------------------
674 Version cut to support continued development for next release
675 preserving the 1.11.* versions for release 1 (Amber) and
680 2019 October 31; version 1.10.2
681 -------------------------------
683 Provide the means to increase the payload size of a received

709 corrected a unit test
713 2019 September 25; version 1.8.3
714 --------------------------------
716 Correct application level test issue causing timing problems
717 during jenkins verification testing at command and merge
719 Handle the NNG connection shutdown status which may now be
720 generated when a connection throug a proxy is reset.
724 2019 September 25; version 1.8.2
725 --------------------------------
727 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
731 2019 September 19; version 1.8.1
732 --------------------------------
734 Correct missing constant for wrappers.
738 2019 September 19; version 1.8.0
739 --------------------------------
741 New message types added:
742 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
746 2019 September 17; version 1.7.0
747 --------------------------------
749 Initial connection mode now defaults to asynchronous. Set
750 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
751 invoked to revert to synchronous first TCP connections.
752 (Recovery connection attempts have always been asynchronous).
756 2019 September 3; version 1.6.0
757 -------------------------------
759 Fix bug in the rmr_rts_msg() function. If a return to sender
760 message failed, the source IP address was not correctly
761 adjusted and could cause the message to be "reflected" back
762 to the sender on a retry.
764 Added the ability to set the source "ID" via an environment
765 var (RMR_SRC_ID). When present in the environment, the string
766 will be placed in to the message header as the source and
767 thus be used by an application calling rmr_rts_smg() to
768 return a response to the sender. If this environment variable
769 is not present, the host name (original behaviour) is used.
773 2019 August 26; version 1.4.0
774 -----------------------------
776 New message types were added.
780 2019 August 16; version 1.3.0
781 -----------------------------
783 New mesage types added.
787 2019 August 13; version 1.2.0 (API change, non-breaking)
788 --------------------------------------------------------
790 The function rmr_get_xact() was added to proide a convenient
791 way to extract the transaction field from a message.
795 2019 August 8; version 1.1.0 (API change)
796 -----------------------------------------
798 This change should be backward compatable/non-breaking A new
799 field has been added to the message buffer (rmr_mbuf_t). This
800 field (tp_state) is used to communicate the errno value that
801 the transport mechanism might set during send and/or receive
802 operations. C programmes should continue to use errno
803 directly, but in some environments wrappers may not be able
804 to access errno and this provides the value to them. See the
805 rmr_alloc_msg manual page for more details.
809 2019 August 6; version 1.0.45 (build changes)
810 ---------------------------------------------
812 Support for the Nanomsg transport library has been dropped.
813 The library librmr.* will no longer be included in packages.
815 Packages will install RMR libraries into the system preferred
816 target directory. On some systems this is /usr/local/lib
817 and on others it is /usr/local/lib64. The diretory is
818 determined by the sytem on which the package is built and
819 NOT by the system installing the package, so it's possible
820 that the RMR libraries end up in a strange location if the
821 .deb or .rpm file was generated on a Linux flavour that
822 has a different preference than the one where the package
827 2019 August 6; version 1.0.44 (API change)
828 ------------------------------------------
830 Added a new message type constant.
834 2019 July 15; Version 1.0.39 (bug fix)
835 --------------------------------------
837 Prevent unnecessary usleep in retry loop.
841 2019 July 12; Version 1.0.38 (API change)
842 -----------------------------------------
844 Added new message types to RIC_message_types.h.
848 2019 July 11; Version 1.0.37
849 ----------------------------
852 librmr and librmr_nng
853 - Add message buffer API function rmr_trace_ref()
854 (see rmr_trace_ref.3 manual page in dev package).
858 2020 April 8; Version n/a
