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.

119 2020 July 9; version 4.1.3
120 --------------------------
122 Allow RTS messages to be sent before the arrival of the
123 initial route table. Calls to RTS (heart beat responses)
124 prior to the initial route table load could cause a crash if

206 2020 April 21; version 4.0.0
207 ----------------------------
209 The NNG based libraries are no longer included in the RMR
210 packages. This is considered a breaking change as NNG will
211 not be supported by default. It is still possible to build
212 with RMR-NNG libraries, but that is the exception. The API
213 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
214 means that the underlying transport mechanism is limited only
217 The rmr_rcv_specific() function has been deprecated as it was
218 necessary only for NNG and Nanomsg support. Its use should be
223 2020 April 20; version 3.8.2

271 2020 April 9; version 3.7.1
272 ---------------------------
274 The max length restriction for receiving messages when using
275 SI95 has been removed. The length supplied during
276 initialisation is used as the "normal maximum" and default
277 buffer allocation size, but messages arriving which are
278 larger are accepted. (RIC-309)
282 2020 April 7; version 3.7.0
283 ---------------------------
285 The health check support programme was renamed to rmr_probe

557 -------------------------------
559 Version cut to support continued development for next release

602 during jenkins verification testing at command and merge
604 Handle the NNG connection shutdown status which may now be
605 generated when a connection throug a proxy is reset.
609 2019 September 25; version 1.8.2
610 --------------------------------
612 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
616 2019 September 19; version 1.8.1
617 --------------------------------
619 Correct missing constant for wrappers.
623 2019 September 19; version 1.8.0
624 --------------------------------
626 New message types added:
627 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
631 2019 September 17; version 1.7.0
632 --------------------------------
634 Initial connection mode now defaults to asynchronous. Set
635 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
636 invoked to revert to synchronous first TCP connections.
637 (Recovery connection attempts have always been asynchronous).
641 2019 September 3; version 1.6.0
642 -------------------------------
644 Fix bug in the rmr_rts_msg() function. If a return to sender
645 message failed, the source IP address was not correctly
646 adjusted and could cause the message to be "reflected" back
647 to the sender on a retry.
649 Added the ability to set the source "ID" via an environment
650 var (RMR_SRC_ID). When present in the environment, the string
651 will be placed in to the message header as the source and
652 thus be used by an application calling rmr_rts_smg() to
653 return a response to the sender. If this environment variable
654 is not present, the host name (original behaviour) is used.
658 2019 August 26; version 1.4.0
659 -----------------------------
661 New message types were added.
665 2019 August 16; version 1.3.0
666 -----------------------------
668 New mesage types added.
672 2019 August 13; version 1.2.0 (API change, non-breaking)
673 --------------------------------------------------------
675 The function rmr_get_xact() was added to proide a convenient
676 way to extract the transaction field from a message.
680 2019 August 8; version 1.1.0 (API change)
681 -----------------------------------------
683 This change should be backward compatable/non-breaking A new
684 field has been added to the message buffer (rmr_mbuf_t). This
685 field (tp_state) is used to communicate the errno value that
686 the transport mechanism might set during send and/or receive
687 operations. C programmes should continue to use errno
688 directly, but in some environments wrappers may not be able
689 to access errno and this provides the value to them. See the
690 rmr_alloc_msg manual page for more details.
694 2019 August 6; version 1.0.45 (build changes)
695 ---------------------------------------------
697 Support for the Nanomsg transport library has been dropped.
698 The library librmr.* will no longer be included in packages.
700 Packages will install RMR libraries into the system preferred
701 target directory. On some systems this is /usr/local/lib
702 and on others it is /usr/local/lib64. The diretory is
703 determined by the sytem on which the package is built and
704 NOT by the system installing the package, so it's possible
705 that the RMR libraries end up in a strange location if the
706 .deb or .rpm file was generated on a Linux flavour that
707 has a different preference than the one where the package
712 2019 August 6; version 1.0.44 (API change)
713 ------------------------------------------
715 Added a new message type constant.
719 2019 July 15; Version 1.0.39 (bug fix)
720 --------------------------------------
722 Prevent unnecessary usleep in retry loop.
726 2019 July 12; Version 1.0.38 (API change)
727 -----------------------------------------
729 Added new message types to RIC_message_types.h.
733 2019 July 11; Version 1.0.37
734 ----------------------------
737 librmr and librmr_nng
738 - Add message buffer API function rmr_trace_ref()
739 (see rmr_trace_ref.3 manual page in dev package).
743 2020 April 8; Version n/a
744 -------------------------
746 RMR Python moved to Python Xapp Framework
747 (https://gerrit.o-ran-sc.org/r/admin/repos/ric-plt/xapp-frame-py)
751 2020 February 29; Version 2.4.0
752 -------------------------------
754 Add consolidated testing under CMake Add support binary for
755 health check (SI95 only)
759 2020 February 28; Version 2.3.6
760 -------------------------------
762 Fix bug in Rt. Mgr comm which prevented table ID from being
763 sent on ack message (RIC-232).
