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 2020 October 2; Version 4.3.0
26 -----------------------------
28 Add message types for anomaly detection
32 2020 September 15; Version 4.2.4

79 2020 July 9; version 4.1.3
80 --------------------------
82 Allow RTS messages to be sent before the arrival of the
83 initial route table. Calls to RTS (heart beat responses)
84 prior to the initial route table load could cause a crash if
85 a framework blindly assumes that RTS is valid. (RIC-589)
89 2020 June 22; version 4.1.2
90 ---------------------------
92 Fix typo in RIC Message header file.

111 2020 June 18; version 4.1.0
112 ---------------------------
114 Bump version minor to move away from 4.0.* which will bump
115 for any patches applied back to bronze.
117 Add magic C++ goo to symtab header file allowing C++ xAPPs to
118 use the symbol table directly.

166 2020 April 21; version 4.0.0
167 ----------------------------
169 The NNG based libraries are no longer included in the RMR
170 packages. This is considered a breaking change as NNG will
171 not be supported by default. It is still possible to build
172 with RMR-NNG libraries, but that is the exception. The API
173 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
174 means that the underlying transport mechanism is limited only
177 The rmr_rcv_specific() function has been deprecated as it was
178 necessary only for NNG and Nanomsg support. Its use should be
183 2020 April 20; version 3.8.2

231 2020 April 9; version 3.7.1
232 ---------------------------
234 The max length restriction for receiving messages when using
235 SI95 has been removed. The length supplied during
236 initialisation is used as the "normal maximum" and default
237 buffer allocation size, but messages arriving which are
238 larger are accepted. (RIC-309)
242 2020 April 7; version 3.7.0
243 ---------------------------
245 The health check support programme was renamed to rmr_probe

562 during jenkins verification testing at command and merge
564 Handle the NNG connection shutdown status which may now be
565 generated when a connection throug a proxy is reset.
569 2019 September 25; version 1.8.2
570 --------------------------------
572 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
576 2019 September 19; version 1.8.1
577 --------------------------------

583 2019 September 19; version 1.8.0
584 --------------------------------
586 New message types added:
587 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
591 2019 September 17; version 1.7.0
592 --------------------------------
594 Initial connection mode now defaults to asynchronous. Set
595 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
596 invoked to revert to synchronous first TCP connections.
597 (Recovery connection attempts have always been asynchronous).
601 2019 September 3; version 1.6.0
602 -------------------------------
604 Fix bug in the rmr_rts_msg() function. If a return to sender
605 message failed, the source IP address was not correctly
606 adjusted and could cause the message to be "reflected" back
607 to the sender on a retry.
609 Added the ability to set the source "ID" via an environment
610 var (RMR_SRC_ID). When present in the environment, the string
611 will be placed in to the message header as the source and
612 thus be used by an application calling rmr_rts_smg() to
613 return a response to the sender. If this environment variable
614 is not present, the host name (original behaviour) is used.
618 2019 August 26; version 1.4.0
619 -----------------------------
621 New message types were added.
625 2019 August 16; version 1.3.0
626 -----------------------------
628 New mesage types added.
632 2019 August 13; version 1.2.0 (API change, non-breaking)
633 --------------------------------------------------------
635 The function rmr_get_xact() was added to proide a convenient
636 way to extract the transaction field from a message.
640 2019 August 8; version 1.1.0 (API change)
641 -----------------------------------------
643 This change should be backward compatable/non-breaking A new
644 field has been added to the message buffer (rmr_mbuf_t). This
645 field (tp_state) is used to communicate the errno value that
646 the transport mechanism might set during send and/or receive
647 operations. C programmes should continue to use errno
648 directly, but in some environments wrappers may not be able
649 to access errno and this provides the value to them. See the
650 rmr_alloc_msg manual page for more details.
654 2019 August 6; version 1.0.45 (build changes)
655 ---------------------------------------------
657 Support for the Nanomsg transport library has been dropped.
658 The library librmr.* will no longer be included in packages.
660 Packages will install RMR libraries into the system preferred
661 target directory. On some systems this is /usr/local/lib
662 and on others it is /usr/local/lib64. The diretory is
663 determined by the sytem on which the package is built and
664 NOT by the system installing the package, so it's possible
665 that the RMR libraries end up in a strange location if the
666 .deb or .rpm file was generated on a Linux flavour that
667 has a different preference than the one where the package
672 2019 August 6; version 1.0.44 (API change)
673 ------------------------------------------
675 Added a new message type constant.
679 2019 July 15; Version 1.0.39 (bug fix)
680 --------------------------------------
682 Prevent unnecessary usleep in retry loop.
686 2019 July 12; Version 1.0.38 (API change)
687 -----------------------------------------
689 Added new message types to RIC_message_types.h.
693 2019 July 11; Version 1.0.37
694 ----------------------------
697 librmr and librmr_nng
698 - Add message buffer API function rmr_trace_ref()
699 (see rmr_trace_ref.3 manual page in dev package).
703 2020 April 8; Version n/a
704 -------------------------
706 RMR Python moved to Python Xapp Framework
707 (https://gerrit.o-ran-sc.org/r/admin/repos/ric-plt/xapp-frame-py)
711 2020 February 29; Version 2.4.0
712 -------------------------------
714 Add consolidated testing under CMake Add support binary for
715 health check (SI95 only)
719 2020 February 28; Version 2.3.6
720 -------------------------------
722 Fix bug in Rt. Mgr comm which prevented table ID from being
723 sent on ack message (RIC-232).
