31 2022 May 11; version 4.8.3
32 Added config transfer related message types (RIC-638)
34 2022 January 17; version 4.8.2
35 Fixes routing statistics printout crash (RIC-872).
37 2022 January 7; version 4.8.1
38 Re-enables RMR libary's module tests (RIC-861).
39 Creates a new unit test for the debugging rmr rx queue API.
40 Fixes some bugs and possible memory likeage in SI95 code.
42 2021 December 2; version 4.8.0
43 Fixing memory leak in python support function (RIC-858).
44 New API added for debugging rmr rx queue (RIC-838).
46 2021 April 22; version 4.7.4
47 Beef up unit testing in SI package and fix a few static analysis
50 2021 April 19; version 4.7.3
51 Correct flag check bug in route table functions (RIC-777).
53 2021 April 9; version 4.7.2
54 Ensure that route table update received from route generator is not
55 applied before a full route table is received.
57 2021 April 2; version 4.7.1
58 Correct issues found during static code analysis.
60 2021 March 31; version 4.7.0
61 The route table collector thread will capture the current "offering"
62 from the Route Manager (table generator) if the RMR_SEED_RT environment
65 2021 March 10; version 4.6.1
66 Corrected unit test "framework" to make manual testing easier, and to
67 add the ability to set the code optimisation level via the CMake
68 command line parameter OPT_LEVEL=n.
70 2021 February 22; Version 4.6.0
71 Enhanced to use millisecond based timestamps when writing log messages.
74 Enhanced to eliminate the reqirement that the file specified by the
75 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
76 will correctly find this file if it is created after initialisation.
77 Further, if the environment variable is not given, the user may create
78 and populate /tmp/rmr.v at any time and the contents of this file will
79 be used as if it were supplied via the environment variable. This should
80 make debugging in existing containers easier.
82 Enhanced to send an alarm manager when the user application is not
83 receiving messages fast enough. The original messages written to
84 the standard error are still generated. (RIC-204)
86 2021 January 21; Version 4.5.2

121 Changes to address a potential race condition when route tables
122 arrive in quick succession. (RIC-674)
124 2020 October 30; Version 4.3.1
125 Changes to address code analyser scans and two bug fixes identified
126 while addressing the analysis data. (RIC-673)

137 2020 August 4; Version 4.2.2
138 Correct bug in the rmr_probe support utility when -r option is used
139 on the command line (RIC-644)
141 2020 August 4; Version 4.2.1
142 Add additional environment variable dump if RMR_LOG_VLEVEL set to
145 2020 August 3; Version 4.2.0
146 Add support for the RMR_RTREQ_FREQ environment variable to control
147 the request frequency for a new route table (default 5s if not
150 2020 July 21; Version 4.1.4
151 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
153 2020 July 9; version 4.1.3
154 Allow RTS messages to be sent before the arrival of the initial
155 route table. Calls to RTS (heart beat responses) prior to the
156 initial route table load could cause a crash if a framework
157 blindly assumes that RTS is valid. (RIC-589)
159 2020 June 22; version 4.1.2
160 Fix typo in RIC Message header file.
162 Add document for message type constants and the scripts
165 2020 June 22; version 4.1.1

171 RAN_E2_RESET_RESP (12009)
173 2020 June 18; version 4.1.0
174 Bump version minor to move away from 4.0.* which will bump for any
175 patches applied back to bronze.

193 2020 April 22; version 4.0.1
194 Correct message type constant for Traffic Steering predication (RIC-342)
196 2020 April 21; version 4.0.0
197 The NNG based libraries are no longer included in the RMR packages.
198 This is considered a breaking change as NNG will not be supported by
199 default. It is still possible to build with RMR-NNG libraries, but
200 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
201 Upgrading to 4.0.0 only means that the underlying transport mechanism
202 is limited only to SI95.
204 The rmr_rcv_specific() function has been deprecated as it was necessary
205 only for NNG and Nanomsg support. Its use should be discontinued.
207 2020 April 20; version 3.8.2

209 table updates. (RIC-336)
211 2020 April 20; version 3.8.1

217 Change debugging in route table collector to avoid possible
218 segment fault when in level 2 debug (RIC-335)
220 2020 April 15; version 3.7.4
221 Add missing message type to header file (RIC-334)
223 2020 April 14; version 3.7.3

226 2020 April 10; version 3.7.2
227 Fix bug related to static route table only mode (RIC-331)
229 2020 April 9; version 3.7.1
230 The max length restriction for receiving messages when using SI95 has
231 been removed. The length supplied during initialisation is used as
232 the "normal maximum" and default buffer allocation size, but messages
233 arriving which are larger are accepted. (RIC-309)
235 2020 April 7; version 3.7.0
236 The health check support programme was renamed to rmr_probe (RIC-308).
238 2020 April 6; version 3.6.6
239 Correct bug in SI95 address conversion module (RIC-327)
240 Correct bug in SI initialisation module
242 2020 April 2; version 3.6.5

244 use as a listen target (RIC-307)
246 2020 April 1; version 3.6.4
247 Correct potential nil pointer use in the NNG interface (RIC-303)
248 Correct issue preventing CI build without a container
250 2020 March 30; version 3.6.3
251 Correct the max receive message size constant in rmr.h (RIC-301)
253 2020 March 23; version 3.6.2

302 a request for table update.
304 2020 February 14; version 3.1.3
305 Fix bug in SIsend which was causing a core dump in some cases

334 Enable support for dynamic route table updates via RMR session.
336 2020 January 16; version 3.0.0
337 Introduce support for SI95 transport library to replace NNG.
338 (RMR library versions will use leading odd numbers to avoid tag collisions
339 with the wrapper tags which will use even numbers.)
341 2019 December 9; version 1.13.1
342 Correct documentation and missing rel-notes update for RTD.
344 2019 December 6; version 1.13.0

350 was not always copied.
352 2019 November 13; version 1.12.1
353 New message type constants added to support A1.
355 2019 November 4; version 1.11.0
356 Version bump to move away from the 1.10.* to distinguish between
357 release A and the trial.
359 2019 November 7; version 1.12.0
360 Version cut to support continued development for next release
361 preserving the 1.11.* versions for release 1 (Amber) and
364 2019 October 31; version 1.10.2
365 Provide the means to increase the payload size of a received message
366 without losing the data needed to use the rmr_rts_msg() funciton.
368 2019 October 21; version 1.10.1
369 Fix to prevent null message buffer from being returned by the timeout
370 receive function if the function is passed one to reuse.
372 2019 October 21; version 1.10.1
373 Add periodic dump of send count info to stderr.
375 2019 September 27; version 1.9.0
376 Python bindings added receive all queued function and corrected a unit test
378 2019 September 25; version 1.8.3
379 Correct application level test issue causing timing problems during
380 jenkins verification testing at command and merge
382 Handle the NNG connection shutdown status which may now be
383 generated when a connection throug a proxy is reset.
385 2019 September 25; version 1.8.2
386 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
388 2019 September 19; version 1.8.1
389 Correct missing constant for wrappers.
391 2019 September 19; version 1.8.0
392 New message types added:
393 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
395 2019 September 17; version 1.7.0
396 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
397 in the environment before rmr_init() is invoked to revert to
398 synchronous first TCP connections. (Recovery connection attempts
399 have always been asynchronous).
401 2019 September 3; version 1.6.0
402 Fix bug in the rmr_rts_msg() function. If a return to sender message
403 failed, the source IP address was not correctly adjusted and could
404 cause the message to be "reflected" back to the sender on a retry.
406 Added the ability to set the source "ID" via an environment var
407 (RMR_SRC_ID). When present in the environment, the string will
408 be placed in to the message header as the source and thus be used
409 by an application calling rmr_rts_smg() to return a response to
410 the sender. If this environment variable is not present, the host
411 name (original behaviour) is used.
413 2019 August 26; version 1.4.0
414 New message types were added.
416 2019 August 16; version 1.3.0
417 New mesage types added.
419 2019 August 13; version 1.2.0 (API change, non-breaking)
420 The function rmr_get_xact() was added to proide a convenient
421 way to extract the transaction field from a message.
423 2019 August 8; version 1.1.0 (API change)
424 This change should be backward compatable/non-breaking
425 A new field has been added to the message buffer (rmr_mbuf_t).
426 This field (tp_state) is used to communicate the errno value
427 that the transport mechanism might set during send and/or
428 receive operations. C programmes should continue to use
429 errno directly, but in some environments wrappers may not be
430 able to access errno and this provides the value to them.
431 See the rmr_alloc_msg manual page for more details.
433 2019 August 6; version 1.0.45 (build changes)
434 Support for the Nanomsg transport library has been dropped.
435 The library librmr.* will no longer be included in packages.
437 Packages will install RMR libraries into the system preferred
438 target directory. On some systems this is /usr/local/lib
439 and on others it is /usr/local/lib64. The diretory is
440 determined by the sytem on which the package is built and
441 NOT by the system installing the package, so it's possible
442 that the RMR libraries end up in a strange location if the
443 .deb or .rpm file was generated on a Linux flavour that
444 has a different preference than the one where the package
447 2019 August 6; version 1.0.44 (API change)
448 Added a new message type constant.
450 2019 July 15; Version 1.0.39 (bug fix)
451 Prevent unnecessary usleep in retry loop.
453 2019 July 12; Version 1.0.38 (API change)
454 Added new message types to RIC_message_types.h.
456 2019 July 11; Version 1.0.37
458 librmr and librmr_nng
459 - Add message buffer API function rmr_trace_ref()
460 (see rmr_trace_ref.3 manual page in dev package).
