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.

81 ------------------------------
83 Fixing memory leak in python support function (RIC-858).
84 New API added for debugging rmr rx queue (RIC-838).
88 2021 April 22; version 4.7.4

92 analysis bugs. (RIC-777)
96 2021 April 19; version 4.7.3
97 ----------------------------
99 Correct flag check bug in route table functions (RIC-777).
103 2021 April 9; version 4.7.2

118 2021 March 31; version 4.7.0
119 ----------------------------
121 The route table collector thread will capture the current
122 "offering" from the Route Manager (table generator) if the
123 RMR_SEED_RT environment variable is set.
127 2021 March 10; version 4.6.1
128 ----------------------------
130 Corrected unit test "framework" to make manual testing
131 easier, and to add the ability to set the code optimisation
132 level via the CMake command line parameter OPT_LEVEL=n.
136 2021 February 22; Version 4.6.0
137 -------------------------------
139 Enhanced to use millisecond based timestamps when writing log
142 Enhanced to eliminate the reqirement that the file specified
143 by the RMR_VCTL_FILE environment variable exist when RMR is
144 initialised. RMR will correctly find this file if it is
145 created after initialisation. Further, if the environment
146 variable is not given, the user may create and populate
147 /tmp/rmr.v at any time and the contents of this file will be
148 used as if it were supplied via the environment variable.
149 This should make debugging in existing containers easier.
151 Enhanced to send an alarm manager when the user application
152 is not receiving messages fast enough. The original messages
153 written to the standard error are still generated. (RIC-204)

305 2020 July 9; version 4.1.3
306 --------------------------
308 Allow RTS messages to be sent before the arrival of the
309 initial route table. Calls to RTS (heart beat responses)
310 prior to the initial route table load could cause a crash if
311 a framework blindly assumes that RTS is valid. (RIC-589)
315 2020 June 22; version 4.1.2
316 ---------------------------
318 Fix typo in RIC Message header file.
320 Add document for message type constants and the scripts which

392 2020 April 21; version 4.0.0
393 ----------------------------
395 The NNG based libraries are no longer included in the RMR
396 packages. This is considered a breaking change as NNG will
397 not be supported by default. It is still possible to build
398 with RMR-NNG libraries, but that is the exception. The API
399 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
400 means that the underlying transport mechanism is limited only
403 The rmr_rcv_specific() function has been deprecated as it was
404 necessary only for NNG and Nanomsg support. Its use should be
409 2020 April 20; version 3.8.2

457 2020 April 9; version 3.7.1
458 ---------------------------
460 The max length restriction for receiving messages when using
461 SI95 has been removed. The length supplied during
462 initialisation is used as the "normal maximum" and default
463 buffer allocation size, but messages arriving which are
464 larger are accepted. (RIC-309)
468 2020 April 7; version 3.7.0
469 ---------------------------
471 The health check support programme was renamed to rmr_probe

730 New message type constants added to support A1.
734 2019 November 4; version 1.11.0
735 -------------------------------
737 Version bump to move away from the 1.10.* to distinguish
738 between release A and the trial.
742 2019 November 7; version 1.12.0
743 -------------------------------
745 Version cut to support continued development for next release
746 preserving the 1.11.* versions for release 1 (Amber) and

795 2019 September 25; version 1.8.2
796 --------------------------------
798 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
802 2019 September 19; version 1.8.1
803 --------------------------------
805 Correct missing constant for wrappers.
809 2019 September 19; version 1.8.0
810 --------------------------------
812 New message types added:
813 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
817 2019 September 17; version 1.7.0
818 --------------------------------
820 Initial connection mode now defaults to asynchronous. Set
821 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
822 invoked to revert to synchronous first TCP connections.
823 (Recovery connection attempts have always been asynchronous).
827 2019 September 3; version 1.6.0
828 -------------------------------
830 Fix bug in the rmr_rts_msg() function. If a return to sender
831 message failed, the source IP address was not correctly
832 adjusted and could cause the message to be "reflected" back
833 to the sender on a retry.
835 Added the ability to set the source "ID" via an environment
836 var (RMR_SRC_ID). When present in the environment, the string
837 will be placed in to the message header as the source and
838 thus be used by an application calling rmr_rts_smg() to
839 return a response to the sender. If this environment variable
840 is not present, the host name (original behaviour) is used.
844 2019 August 26; version 1.4.0
845 -----------------------------
847 New message types were added.
851 2019 August 16; version 1.3.0
852 -----------------------------
854 New mesage types added.
858 2019 August 13; version 1.2.0 (API change, non-breaking)
859 --------------------------------------------------------
861 The function rmr_get_xact() was added to proide a convenient
862 way to extract the transaction field from a message.
866 2019 August 8; version 1.1.0 (API change)
867 -----------------------------------------
869 This change should be backward compatable/non-breaking A new
870 field has been added to the message buffer (rmr_mbuf_t). This
871 field (tp_state) is used to communicate the errno value that
872 the transport mechanism might set during send and/or receive
873 operations. C programmes should continue to use errno
874 directly, but in some environments wrappers may not be able
875 to access errno and this provides the value to them. See the
876 rmr_alloc_msg manual page for more details.
880 2019 August 6; version 1.0.45 (build changes)
881 ---------------------------------------------
883 Support for the Nanomsg transport library has been dropped.
884 The library librmr.* will no longer be included in packages.
886 Packages will install RMR libraries into the system preferred
887 target directory. On some systems this is /usr/local/lib
888 and on others it is /usr/local/lib64. The diretory is
889 determined by the sytem on which the package is built and
890 NOT by the system installing the package, so it's possible
891 that the RMR libraries end up in a strange location if the
892 .deb or .rpm file was generated on a Linux flavour that
893 has a different preference than the one where the package
898 2019 August 6; version 1.0.44 (API change)
899 ------------------------------------------
901 Added a new message type constant.
905 2019 July 15; Version 1.0.39 (bug fix)
906 --------------------------------------

924 - Add message buffer API function rmr_trace_ref()
925 (see rmr_trace_ref.3 manual page in dev package).
929 2020 April 8; Version n/a
930 -------------------------
932 RMR Python moved to Python Xapp Framework
