8 2021 March 10; version 4.6.1
9 Corrected unit test "framework" to make manual testing easier, and to
10 add the ability to set the code optimisation level via the CMake
11 command line parameter OPT_LEVEL=n.
13 2021 February 22; Version 4.6.0
14 Enhanced to use millisecond based timestamps when writing log messages.
17 Enhanced to eliminate the reqirement that the file specified by the
18 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
19 will correctly find this file if it is created after initialisation.
20 Further, if the environment variable is not given, the user may create
21 and populate /tmp/rmr.v at any time and the contents of this file will
22 be used as if it were supplied via the environment variable. This should
23 make debugging in existing containers easier.
25 Enhanced to send an alarm manager when the user application is not
26 receiving messages fast enough. The original messages written to
27 the standard error are still generated. (RIC-204)
29 2021 January 21; Version 4.5.2
30 Fixes the excessive TCP session bug when sending to a slow receiver
31 and a related segment fault because of too many open file descriptors.

65 arrive in quick succession. (RIC-674)
67 2020 October 30; Version 4.3.1
68 Changes to address code analyser scans and two bug fixes identified
69 while addressing the analysis data. (RIC-673)

88 2020 August 3; Version 4.2.0
89 Add support for the RMR_RTREQ_FREQ environment variable to control
90 the request frequency for a new route table (default 5s if not
93 2020 July 21; Version 4.1.4
94 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
96 2020 July 9; version 4.1.3
97 Allow RTS messages to be sent before the arrival of the initial
98 route table. Calls to RTS (heart beat responses) prior to the
99 initial route table load could cause a crash if a framework
100 blindly assumes that RTS is valid. (RIC-589)
102 2020 June 22; version 4.1.2
103 Fix typo in RIC Message header file.
105 Add document for message type constants and the scripts
108 2020 June 22; version 4.1.1

114 RAN_E2_RESET_RESP (12009)
116 2020 June 18; version 4.1.0
117 Bump version minor to move away from 4.0.* which will bump for any
118 patches applied back to bronze.

136 2020 April 22; version 4.0.1
137 Correct message type constant for Traffic Steering predication (RIC-342)
139 2020 April 21; version 4.0.0
140 The NNG based libraries are no longer included in the RMR packages.
141 This is considered a breaking change as NNG will not be supported by
142 default. It is still possible to build with RMR-NNG libraries, but
143 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
144 Upgrading to 4.0.0 only means that the underlying transport mechanism
145 is limited only to SI95.
147 The rmr_rcv_specific() function has been deprecated as it was necessary
148 only for NNG and Nanomsg support. Its use should be discontinued.
150 2020 April 20; version 3.8.2
151 Fix bug which was preventing an instance receiving dynamic route
152 table updates. (RIC-336)
154 2020 April 20; version 3.8.1

170 Fix bug related to static route table only mode (RIC-331)
172 2020 April 9; version 3.7.1
173 The max length restriction for receiving messages when using SI95 has
174 been removed. The length supplied during initialisation is used as
175 the "normal maximum" and default buffer allocation size, but messages
176 arriving which are larger are accepted. (RIC-309)
178 2020 April 7; version 3.7.0
179 The health check support programme was renamed to rmr_probe (RIC-308).

277 Enable support for dynamic route table updates via RMR session.
279 2020 January 16; version 3.0.0
280 Introduce support for SI95 transport library to replace NNG.
281 (RMR library versions will use leading odd numbers to avoid tag collisions
282 with the wrapper tags which will use even numbers.)
284 2019 December 9; version 1.13.1
285 Correct documentation and missing rel-notes update for RTD.
287 2019 December 6; version 1.13.0

293 was not always copied.
295 2019 November 13; version 1.12.1
296 New message type constants added to support A1.
298 2019 November 4; version 1.11.0
299 Version bump to move away from the 1.10.* to distinguish between

304 preserving the 1.11.* versions for release 1 (Amber) and
307 2019 October 31; version 1.10.2
308 Provide the means to increase the payload size of a received message

311 2019 October 21; version 1.10.1
312 Fix to prevent null message buffer from being returned by the timeout
313 receive function if the function is passed one to reuse.
315 2019 October 21; version 1.10.1
316 Add periodic dump of send count info to stderr.
318 2019 September 27; version 1.9.0
319 Python bindings added receive all queued function and corrected a unit test
321 2019 September 25; version 1.8.3
322 Correct application level test issue causing timing problems during
323 jenkins verification testing at command and merge
325 Handle the NNG connection shutdown status which may now be

328 2019 September 25; version 1.8.2
329 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
331 2019 September 19; version 1.8.1
332 Correct missing constant for wrappers.
334 2019 September 19; version 1.8.0
335 New message types added:
336 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
338 2019 September 17; version 1.7.0
339 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
340 in the environment before rmr_init() is invoked to revert to
341 synchronous first TCP connections. (Recovery connection attempts
342 have always been asynchronous).
344 2019 September 3; version 1.6.0
345 Fix bug in the rmr_rts_msg() function. If a return to sender message
346 failed, the source IP address was not correctly adjusted and could
347 cause the message to be "reflected" back to the sender on a retry.
349 Added the ability to set the source "ID" via an environment var
350 (RMR_SRC_ID). When present in the environment, the string will
351 be placed in to the message header as the source and thus be used
352 by an application calling rmr_rts_smg() to return a response to
353 the sender. If this environment variable is not present, the host
354 name (original behaviour) is used.
356 2019 August 26; version 1.4.0
357 New message types were added.
359 2019 August 16; version 1.3.0
360 New mesage types added.
362 2019 August 13; version 1.2.0 (API change, non-breaking)
363 The function rmr_get_xact() was added to proide a convenient
364 way to extract the transaction field from a message.
366 2019 August 8; version 1.1.0 (API change)
367 This change should be backward compatable/non-breaking
368 A new field has been added to the message buffer (rmr_mbuf_t).
369 This field (tp_state) is used to communicate the errno value
370 that the transport mechanism might set during send and/or
371 receive operations. C programmes should continue to use
372 errno directly, but in some environments wrappers may not be
373 able to access errno and this provides the value to them.
374 See the rmr_alloc_msg manual page for more details.
376 2019 August 6; version 1.0.45 (build changes)
377 Support for the Nanomsg transport library has been dropped.
378 The library librmr.* will no longer be included in packages.
380 Packages will install RMR libraries into the system preferred
381 target directory. On some systems this is /usr/local/lib
382 and on others it is /usr/local/lib64. The diretory is
383 determined by the sytem on which the package is built and
384 NOT by the system installing the package, so it's possible
385 that the RMR libraries end up in a strange location if the
386 .deb or .rpm file was generated on a Linux flavour that
387 has a different preference than the one where the package
390 2019 August 6; version 1.0.44 (API change)
391 Added a new message type constant.
393 2019 July 15; Version 1.0.39 (bug fix)
394 Prevent unnecessary usleep in retry loop.
396 2019 July 12; Version 1.0.38 (API change)
397 Added new message types to RIC_message_types.h.
399 2019 July 11; Version 1.0.37
401 librmr and librmr_nng
402 - Add message buffer API function rmr_trace_ref()
403 (see rmr_trace_ref.3 manual page in dev package).
