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 June 22; version 4.1.1
26 ---------------------------
28 Add new message types to RIC header file for
32 RAN_E2_RESET_REQ (12008)

95 The NNG based libraries are no longer included in the RMR
96 packages. This is considered a breaking change as NNG will
97 not be supported by default. It is still possible to build
98 with RMR-NNG libraries, but that is the exception. The API
99 between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only
100 means that the underlying transport mechanism is limited only
103 The rmr_rcv_specific() function has been deprecated as it was
104 necessary only for NNG and Nanomsg support. Its use should be

509 2019 September 19; version 1.8.0

512 New message types added:
513 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
517 2019 September 17; version 1.7.0
518 --------------------------------
520 Initial connection mode now defaults to asynchronous. Set
521 RMR_ASYNC_CONN=0 in the environment before rmr_init() is
522 invoked to revert to synchronous first TCP connections.
523 (Recovery connection attempts have always been asynchronous).
527 2019 September 3; version 1.6.0
528 -------------------------------
530 Fix bug in the rmr_rts_msg() function. If a return to sender
531 message failed, the source IP address was not correctly
532 adjusted and could cause the message to be "reflected" back
533 to the sender on a retry.
535 Added the ability to set the source "ID" via an environment
536 var (RMR_SRC_ID). When present in the environment, the string
537 will be placed in to the message header as the source and
538 thus be used by an application calling rmr_rts_smg() to
539 return a response to the sender. If this environment variable
540 is not present, the host name (original behaviour) is used.
544 2019 August 26; version 1.4.0
545 -----------------------------
547 New message types were added.
551 2019 August 16; version 1.3.0
552 -----------------------------
554 New mesage types added.
558 2019 August 13; version 1.2.0 (API change, non-breaking)
559 --------------------------------------------------------
561 The function rmr_get_xact() was added to proide a convenient
562 way to extract the transaction field from a message.
566 2019 August 8; version 1.1.0 (API change)
567 -----------------------------------------
569 This change should be backward compatable/non-breaking A new
570 field has been added to the message buffer (rmr_mbuf_t). This
571 field (tp_state) is used to communicate the errno value that
572 the transport mechanism might set during send and/or receive
573 operations. C programmes should continue to use errno
574 directly, but in some environments wrappers may not be able
575 to access errno and this provides the value to them. See the
576 rmr_alloc_msg manual page for more details.
580 2019 August 6; version 1.0.45 (build changes)
581 ---------------------------------------------
583 Support for the Nanomsg transport library has been dropped.
584 The library librmr.* will no longer be included in packages.
586 Packages will install RMR libraries into the system preferred
587 target directory. On some systems this is /usr/local/lib
588 and on others it is /usr/local/lib64. The diretory is
589 determined by the sytem on which the package is built and
590 NOT by the system installing the package, so it's possible
591 that the RMR libraries end up in a strange location if the
592 .deb or .rpm file was generated on a Linux flavour that
593 has a different preference than the one where the package
598 2019 August 6; version 1.0.44 (API change)
599 ------------------------------------------
601 Added a new message type constant.
605 2019 July 15; Version 1.0.39 (bug fix)
606 --------------------------------------
608 Prevent unnecessary usleep in retry loop.
612 2019 July 12; Version 1.0.38 (API change)
613 -----------------------------------------
615 Added new message types to RIC_message_types.h.
619 2019 July 11; Version 1.0.37
620 ----------------------------
623 librmr and librmr_nng
624 - Add message buffer API function rmr_trace_ref()
625 (see rmr_trace_ref.3 manual page in dev package).
629 2020 April 8; Version n/a
