28 2022 May 11; version 4.8.3
29 Added config transfer related message types (RIC-638)
31 2022 January 17; version 4.8.2
32 Fixes routing statistics printout crash (RIC-872).
34 2022 January 7; version 4.8.1

37 Fixes some bugs and possible memory likeage in SI95 code.
39 2021 December 2; version 4.8.0
40 Fixing memory leak in python support function (RIC-858).
41 New API added for debugging rmr rx queue (RIC-838).
43 2021 April 22; version 4.7.4
44 Beef up unit testing in SI package and fix a few static analysis
47 2021 April 19; version 4.7.3
48 Correct flag check bug in route table functions (RIC-777).
50 2021 April 9; version 4.7.2
51 Ensure that route table update received from route generator is not
52 applied before a full route table is received.
54 2021 April 2; version 4.7.1
55 Correct issues found during static code analysis.
57 2021 March 31; version 4.7.0
58 The route table collector thread will capture the current "offering"
59 from the Route Manager (table generator) if the RMR_SEED_RT environment
62 2021 March 10; version 4.6.1
63 Corrected unit test "framework" to make manual testing easier, and to
64 add the ability to set the code optimisation level via the CMake
65 command line parameter OPT_LEVEL=n.
67 2021 February 22; Version 4.6.0
68 Enhanced to use millisecond based timestamps when writing log messages.
71 Enhanced to eliminate the reqirement that the file specified by the
72 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
73 will correctly find this file if it is created after initialisation.
74 Further, if the environment variable is not given, the user may create
75 and populate /tmp/rmr.v at any time and the contents of this file will
76 be used as if it were supplied via the environment variable. This should
77 make debugging in existing containers easier.
79 Enhanced to send an alarm manager when the user application is not
80 receiving messages fast enough. The original messages written to
81 the standard error are still generated. (RIC-204)
83 2021 January 21; Version 4.5.2

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

134 2020 August 4; Version 4.2.2
135 Correct bug in the rmr_probe support utility when -r option is used
136 on the command line (RIC-644)
138 2020 August 4; Version 4.2.1
139 Add additional environment variable dump if RMR_LOG_VLEVEL set to
142 2020 August 3; Version 4.2.0
143 Add support for the RMR_RTREQ_FREQ environment variable to control
144 the request frequency for a new route table (default 5s if not
147 2020 July 21; Version 4.1.4
148 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
150 2020 July 9; version 4.1.3
151 Allow RTS messages to be sent before the arrival of the initial
152 route table. Calls to RTS (heart beat responses) prior to the
153 initial route table load could cause a crash if a framework
154 blindly assumes that RTS is valid. (RIC-589)
156 2020 June 22; version 4.1.2
157 Fix typo in RIC Message header file.
159 Add document for message type constants and the scripts

170 2020 June 18; version 4.1.0
171 Bump version minor to move away from 4.0.* which will bump for any
172 patches applied back to bronze.

191 Correct message type constant for Traffic Steering predication (RIC-342)
193 2020 April 21; version 4.0.0
194 The NNG based libraries are no longer included in the RMR packages.
195 This is considered a breaking change as NNG will not be supported by
196 default. It is still possible to build with RMR-NNG libraries, but
197 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
198 Upgrading to 4.0.0 only means that the underlying transport mechanism
199 is limited only to SI95.
201 The rmr_rcv_specific() function has been deprecated as it was necessary
202 only for NNG and Nanomsg support. Its use should be discontinued.
204 2020 April 20; version 3.8.2
205 Fix bug which was preventing an instance receiving dynamic route
206 table updates. (RIC-336)
208 2020 April 20; version 3.8.1

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

223 2020 April 10; version 3.7.2
224 Fix bug related to static route table only mode (RIC-331)
226 2020 April 9; version 3.7.1
227 The max length restriction for receiving messages when using SI95 has
228 been removed. The length supplied during initialisation is used as
229 the "normal maximum" and default buffer allocation size, but messages
230 arriving which are larger are accepted. (RIC-309)
232 2020 April 7; version 3.7.0
233 The health check support programme was renamed to rmr_probe (RIC-308).
235 2020 April 6; version 3.6.6

244 Correct potential nil pointer use in the NNG interface (RIC-303)
245 Correct issue preventing CI build without a container
247 2020 March 30; version 3.6.3
248 Correct the max receive message size constant in rmr.h (RIC-301)
250 2020 March 23; version 3.6.2

299 a request for table update.
301 2020 February 14; version 3.1.3
302 Fix bug in SIsend which was causing a core dump in some cases

331 Enable support for dynamic route table updates via RMR session.
333 2020 January 16; version 3.0.0
334 Introduce support for SI95 transport library to replace NNG.
335 (RMR library versions will use leading odd numbers to avoid tag collisions
336 with the wrapper tags which will use even numbers.)
338 2019 December 9; version 1.13.1
339 Correct documentation and missing rel-notes update for RTD.
341 2019 December 6; version 1.13.0

346 Fix bug in payload reallocation function; correct length of payload
347 was not always copied.
349 2019 November 13; version 1.12.1
350 New message type constants added to support A1.
352 2019 November 4; version 1.11.0
353 Version bump to move away from the 1.10.* to distinguish between
354 release A and the trial.
356 2019 November 7; version 1.12.0
357 Version cut to support continued development for next release
358 preserving the 1.11.* versions for release 1 (Amber) and
361 2019 October 31; version 1.10.2
362 Provide the means to increase the payload size of a received message
363 without losing the data needed to use the rmr_rts_msg() funciton.
365 2019 October 21; version 1.10.1
366 Fix to prevent null message buffer from being returned by the timeout
367 receive function if the function is passed one to reuse.
369 2019 October 21; version 1.10.1
370 Add periodic dump of send count info to stderr.
372 2019 September 27; version 1.9.0
373 Python bindings added receive all queued function and corrected a unit test
375 2019 September 25; version 1.8.3
376 Correct application level test issue causing timing problems during
377 jenkins verification testing at command and merge
379 Handle the NNG connection shutdown status which may now be
380 generated when a connection throug a proxy is reset.
382 2019 September 25; version 1.8.2
383 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
385 2019 September 19; version 1.8.1
386 Correct missing constant for wrappers.
388 2019 September 19; version 1.8.0
389 New message types added:
390 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
392 2019 September 17; version 1.7.0
393 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
394 in the environment before rmr_init() is invoked to revert to
395 synchronous first TCP connections. (Recovery connection attempts
396 have always been asynchronous).
398 2019 September 3; version 1.6.0
399 Fix bug in the rmr_rts_msg() function. If a return to sender message
400 failed, the source IP address was not correctly adjusted and could
401 cause the message to be "reflected" back to the sender on a retry.
403 Added the ability to set the source "ID" via an environment var
404 (RMR_SRC_ID). When present in the environment, the string will
405 be placed in to the message header as the source and thus be used
406 by an application calling rmr_rts_smg() to return a response to
407 the sender. If this environment variable is not present, the host
408 name (original behaviour) is used.
410 2019 August 26; version 1.4.0
411 New message types were added.
413 2019 August 16; version 1.3.0
414 New mesage types added.
416 2019 August 13; version 1.2.0 (API change, non-breaking)
417 The function rmr_get_xact() was added to proide a convenient
418 way to extract the transaction field from a message.
420 2019 August 8; version 1.1.0 (API change)
421 This change should be backward compatable/non-breaking
422 A new field has been added to the message buffer (rmr_mbuf_t).
423 This field (tp_state) is used to communicate the errno value
424 that the transport mechanism might set during send and/or
425 receive operations. C programmes should continue to use
426 errno directly, but in some environments wrappers may not be
427 able to access errno and this provides the value to them.
428 See the rmr_alloc_msg manual page for more details.
430 2019 August 6; version 1.0.45 (build changes)
431 Support for the Nanomsg transport library has been dropped.
432 The library librmr.* will no longer be included in packages.
434 Packages will install RMR libraries into the system preferred
435 target directory. On some systems this is /usr/local/lib
436 and on others it is /usr/local/lib64. The diretory is
437 determined by the sytem on which the package is built and
438 NOT by the system installing the package, so it's possible
439 that the RMR libraries end up in a strange location if the
440 .deb or .rpm file was generated on a Linux flavour that
441 has a different preference than the one where the package
444 2019 August 6; version 1.0.44 (API change)
445 Added a new message type constant.
447 2019 July 15; Version 1.0.39 (bug fix)
448 Prevent unnecessary usleep in retry loop.
450 2019 July 12; Version 1.0.38 (API change)
451 Added new message types to RIC_message_types.h.
453 2019 July 11; Version 1.0.37
455 librmr and librmr_nng
456 - Add message buffer API function rmr_trace_ref()
457 (see rmr_trace_ref.3 manual page in dev package).
