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 August 4; Version 4.2.1
26 ----------------------------
28 Add additional environment variable dump if RMR_LOG_VLEVEL
33 2020 August 3; Version 4.2.0
34 ----------------------------
36 Add support for the RMR_RTREQ_FREQ environment variable to

43 ---------------------------
45 Fix bug in SI95 -- possible use of pointer after free
50 2020 July 9; version 4.1.3
51 --------------------------
53 Allow RTS messages to be sent before the arrival of the
54 initial route table. Calls to RTS (heart beat responses)
55 prior to the initial route table load could cause a crash if
56 a framework blindly assumes that RTS is valid. (RIC-589)
60 2020 June 22; version 4.1.2
61 ---------------------------
63 Fix typo in RIC Message header file.
65 Add document for message type constants and the scripts which
70 2020 June 22; version 4.1.1

82 2020 June 18; version 4.1.0
83 ---------------------------
85 Bump version minor to move away from 4.0.* which will bump
86 for any patches applied back to bronze.
88 Add magic C++ goo to symtab header file allowing C++ xAPPs to
89 use the symbol table directly.
98 2020 May 06; version 4.0.5

137 2020 April 21; version 4.0.0
138 ----------------------------
140 The NNG based libraries are no longer included in the RMR
141 packages. This is considered a breaking change as NNG will
142 not be supported by default. It is still possible to build
143 with RMR-NNG libraries, but that is the exception. The API
144 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
145 means that the underlying transport mechanism is limited only
148 The rmr_rcv_specific() function has been deprecated as it was
149 necessary only for NNG and Nanomsg support. Its use should be
154 2020 April 20; version 3.8.2

202 2020 April 9; version 3.7.1
203 ---------------------------
205 The max length restriction for receiving messages when using
206 SI95 has been removed. The length supplied during
207 initialisation is used as the "normal maximum" and default
208 buffer allocation size, but messages arriving which are
209 larger are accepted. (RIC-309)
213 2020 April 7; version 3.7.0
214 ---------------------------
216 The health check support programme was renamed to rmr_probe
221 2020 April 6; version 3.6.6

488 -------------------------------
490 Version cut to support continued development for next release

535 Handle the NNG connection shutdown status which may now be

540 2019 September 25; version 1.8.2
541 --------------------------------
543 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
547 2019 September 19; version 1.8.1
548 --------------------------------
550 Correct missing constant for wrappers.
554 2019 September 19; version 1.8.0
555 --------------------------------
557 New message types added:
558 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
562 2019 September 17; version 1.7.0
563 --------------------------------
565 Initial connection mode now defaults to asynchronous. Set
566 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
567 invoked to revert to synchronous first TCP connections.
568 (Recovery connection attempts have always been asynchronous).
572 2019 September 3; version 1.6.0
573 -------------------------------
575 Fix bug in the rmr_rts_msg() function. If a return to sender
576 message failed, the source IP address was not correctly
577 adjusted and could cause the message to be "reflected" back
578 to the sender on a retry.
580 Added the ability to set the source "ID" via an environment
581 var (RMR_SRC_ID). When present in the environment, the string
582 will be placed in to the message header as the source and
583 thus be used by an application calling rmr_rts_smg() to
584 return a response to the sender. If this environment variable
585 is not present, the host name (original behaviour) is used.
589 2019 August 26; version 1.4.0
590 -----------------------------
592 New message types were added.
596 2019 August 16; version 1.3.0
597 -----------------------------
599 New mesage types added.
603 2019 August 13; version 1.2.0 (API change, non-breaking)
604 --------------------------------------------------------
606 The function rmr_get_xact() was added to proide a convenient
607 way to extract the transaction field from a message.
611 2019 August 8; version 1.1.0 (API change)
612 -----------------------------------------
614 This change should be backward compatable/non-breaking A new
615 field has been added to the message buffer (rmr_mbuf_t). This
616 field (tp_state) is used to communicate the errno value that
617 the transport mechanism might set during send and/or receive
618 operations. C programmes should continue to use errno
619 directly, but in some environments wrappers may not be able
620 to access errno and this provides the value to them. See the
621 rmr_alloc_msg manual page for more details.
625 2019 August 6; version 1.0.45 (build changes)
626 ---------------------------------------------
628 Support for the Nanomsg transport library has been dropped.
629 The library librmr.* will no longer be included in packages.
631 Packages will install RMR libraries into the system preferred
632 target directory. On some systems this is /usr/local/lib
633 and on others it is /usr/local/lib64. The diretory is
634 determined by the sytem on which the package is built and
635 NOT by the system installing the package, so it's possible
636 that the RMR libraries end up in a strange location if the
637 .deb or .rpm file was generated on a Linux flavour that
638 has a different preference than the one where the package
643 2019 August 6; version 1.0.44 (API change)
644 ------------------------------------------
646 Added a new message type constant.
650 2019 July 15; Version 1.0.39 (bug fix)
651 --------------------------------------
653 Prevent unnecessary usleep in retry loop.
657 2019 July 12; Version 1.0.38 (API change)
658 -----------------------------------------
660 Added new message types to RIC_message_types.h.
664 2019 July 11; Version 1.0.37
665 ----------------------------
668 librmr and librmr_nng
669 - Add message buffer API function rmr_trace_ref()
670 (see rmr_trace_ref.3 manual page in dev package).
674 2020 April 8; Version n/a
675 -------------------------
677 RMR Python moved to Python Xapp Framework
678 (https://gerrit.o-ran-sc.org/r/admin/repos/ric-plt/xapp-frame-py)
682 2020 February 29; Version 2.4.0
683 -------------------------------
685 Add consolidated testing under CMake Add support binary for
686 health check (SI95 only)
690 2020 February 28; Version 2.3.6
691 -------------------------------
693 Fix bug in Rt. Mgr comm which prevented table ID from being
694 sent on ack message (RIC-232).
