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 February 22; Version 4.6.0
26 -------------------------------
28 Enhanced to use millisecond based timestamps when writing log
31 Enhanced to eliminate the reqirement that the file specified
32 by the RMR_VCTL_FILE environment variable exist when RMR is
33 initialised. RMR will correctly find this file if it is
34 created after initialisation. Further, if the environment
35 variable is not given, the user may create and populate
36 /tmp/rmr.v at any time and the contents of this file will be
37 used as if it were supplied via the environment variable.
38 This should make debugging in existing containers easier.
40 Enhanced to send an alarm manager when the user application
41 is not receiving messages fast enough. The original messages
42 written to the standard error are still generated. (RIC-204)
46 2021 January 21; Version 4.5.2
47 ------------------------------
49 Fixes the excessive TCP session bug when sending to a slow

133 ------------------------------

194 2020 July 9; version 4.1.3
195 --------------------------
197 Allow RTS messages to be sent before the arrival of the
198 initial route table. Calls to RTS (heart beat responses)
199 prior to the initial route table load could cause a crash if
200 a framework blindly assumes that RTS is valid. (RIC-589)
204 2020 June 22; version 4.1.2
205 ---------------------------
207 Fix typo in RIC Message header file.

229 Bump version minor to move away from 4.0.* which will bump
230 for any patches applied back to bronze.
232 Add magic C++ goo to symtab header file allowing C++ xAPPs to

281 2020 April 21; version 4.0.0
282 ----------------------------
284 The NNG based libraries are no longer included in the RMR
285 packages. This is considered a breaking change as NNG will
286 not be supported by default. It is still possible to build
287 with RMR-NNG libraries, but that is the exception. The API
288 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
289 means that the underlying transport mechanism is limited only
292 The rmr_rcv_specific() function has been deprecated as it was
293 necessary only for NNG and Nanomsg support. Its use should be
298 2020 April 20; version 3.8.2

346 2020 April 9; version 3.7.1
347 ---------------------------
349 The max length restriction for receiving messages when using
350 SI95 has been removed. The length supplied during
351 initialisation is used as the "normal maximum" and default
352 buffer allocation size, but messages arriving which are
353 larger are accepted. (RIC-309)
357 2020 April 7; version 3.7.0
358 ---------------------------
360 The health check support programme was renamed to rmr_probe
365 2020 April 6; version 3.6.6
366 ---------------------------
368 Correct bug in SI95 address conversion module (RIC-327)
369 Correct bug in SI initialisation module

612 payload was not always copied.
616 2019 November 13; version 1.12.1
617 --------------------------------
619 New message type constants added to support A1.
623 2019 November 4; version 1.11.0
624 -------------------------------
626 Version bump to move away from the 1.10.* to distinguish
627 between release A and the trial.
631 2019 November 7; version 1.12.0
632 -------------------------------
634 Version cut to support continued development for next release
635 preserving the 1.11.* versions for release 1 (Amber) and
640 2019 October 31; version 1.10.2
641 -------------------------------
643 Provide the means to increase the payload size of a received
644 message without losing the data needed to use the

658 2019 October 21; version 1.10.1
659 -------------------------------
661 Add periodic dump of send count info to stderr.
665 2019 September 27; version 1.9.0
666 --------------------------------
668 Python bindings added receive all queued function and
669 corrected a unit test
673 2019 September 25; version 1.8.3
674 --------------------------------
676 Correct application level test issue causing timing problems
677 during jenkins verification testing at command and merge
679 Handle the NNG connection shutdown status which may now be
680 generated when a connection throug a proxy is reset.
684 2019 September 25; version 1.8.2
685 --------------------------------
687 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
691 2019 September 19; version 1.8.1
692 --------------------------------
694 Correct missing constant for wrappers.
698 2019 September 19; version 1.8.0
699 --------------------------------
701 New message types added:
702 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
706 2019 September 17; version 1.7.0
707 --------------------------------
709 Initial connection mode now defaults to asynchronous. Set
710 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
711 invoked to revert to synchronous first TCP connections.
712 (Recovery connection attempts have always been asynchronous).
716 2019 September 3; version 1.6.0
717 -------------------------------
719 Fix bug in the rmr_rts_msg() function. If a return to sender
720 message failed, the source IP address was not correctly
721 adjusted and could cause the message to be "reflected" back
722 to the sender on a retry.
724 Added the ability to set the source "ID" via an environment
725 var (RMR_SRC_ID). When present in the environment, the string
726 will be placed in to the message header as the source and
727 thus be used by an application calling rmr_rts_smg() to
728 return a response to the sender. If this environment variable
729 is not present, the host name (original behaviour) is used.
733 2019 August 26; version 1.4.0
734 -----------------------------
736 New message types were added.
740 2019 August 16; version 1.3.0
741 -----------------------------
743 New mesage types added.
747 2019 August 13; version 1.2.0 (API change, non-breaking)
748 --------------------------------------------------------
750 The function rmr_get_xact() was added to proide a convenient
751 way to extract the transaction field from a message.
755 2019 August 8; version 1.1.0 (API change)
756 -----------------------------------------
758 This change should be backward compatable/non-breaking A new
759 field has been added to the message buffer (rmr_mbuf_t). This
760 field (tp_state) is used to communicate the errno value that
761 the transport mechanism might set during send and/or receive
762 operations. C programmes should continue to use errno
763 directly, but in some environments wrappers may not be able
764 to access errno and this provides the value to them. See the
765 rmr_alloc_msg manual page for more details.
769 2019 August 6; version 1.0.45 (build changes)
770 ---------------------------------------------
772 Support for the Nanomsg transport library has been dropped.
773 The library librmr.* will no longer be included in packages.
775 Packages will install RMR libraries into the system preferred
776 target directory. On some systems this is /usr/local/lib
777 and on others it is /usr/local/lib64. The diretory is
778 determined by the sytem on which the package is built and
779 NOT by the system installing the package, so it's possible
780 that the RMR libraries end up in a strange location if the
781 .deb or .rpm file was generated on a Linux flavour that
782 has a different preference than the one where the package
787 2019 August 6; version 1.0.44 (API change)
788 ------------------------------------------
790 Added a new message type constant.
794 2019 July 15; Version 1.0.39 (bug fix)
795 --------------------------------------
797 Prevent unnecessary usleep in retry loop.
801 2019 July 12; Version 1.0.38 (API change)
802 -----------------------------------------
804 Added new message types to RIC_message_types.h.
808 2019 July 11; Version 1.0.37
809 ----------------------------
812 librmr and librmr_nng
813 - Add message buffer API function rmr_trace_ref()
814 (see rmr_trace_ref.3 manual page in dev package).
818 2020 April 8; Version n/a
819 -------------------------
821 RMR Python moved to Python Xapp Framework

838 sent on ack message (RIC-232).
