8 2022 Nov 10; version 4.8.4
9 Fixes for errors detected by source code scanning
11 2022 May 11; version 4.8.3
12 Added config transfer related message types (RIC-638)
14 2022 January 17; version 4.8.2
15 Fixes routing statistics printout crash (RIC-872).
17 2022 January 7; version 4.8.1
18 Re-enables RMR libary's module tests (RIC-861).
19 Creates a new unit test for the debugging rmr rx queue API.
20 Fixes some bugs and possible memory likeage in SI95 code.
22 2021 December 2; version 4.8.0
23 Fixing memory leak in python support function (RIC-858).
24 New API added for debugging rmr rx queue (RIC-838).
26 2021 April 22; version 4.7.4
27 Beef up unit testing in SI package and fix a few static analysis
30 2021 April 19; version 4.7.3
31 Correct flag check bug in route table functions (RIC-777).
33 2021 April 9; version 4.7.2
34 Ensure that route table update received from route generator is not
35 applied before a full route table is received.
37 2021 April 2; version 4.7.1
38 Correct issues found during static code analysis.
40 2021 March 31; version 4.7.0
41 The route table collector thread will capture the current "offering"
42 from the Route Manager (table generator) if the RMR_SEED_RT environment
45 2021 March 10; version 4.6.1
46 Corrected unit test "framework" to make manual testing easier, and to
47 add the ability to set the code optimisation level via the CMake
48 command line parameter OPT_LEVEL=n.
50 2021 February 22; Version 4.6.0
51 Enhanced to use millisecond based timestamps when writing log messages.
54 Enhanced to eliminate the reqirement that the file specified by the
55 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
56 will correctly find this file if it is created after initialisation.
57 Further, if the environment variable is not given, the user may create
58 and populate /tmp/rmr.v at any time and the contents of this file will
59 be used as if it were supplied via the environment variable. This should
60 make debugging in existing containers easier.
62 Enhanced to send an alarm manager when the user application is not
63 receiving messages fast enough. The original messages written to
64 the standard error are still generated. (RIC-204)
66 2021 January 21; Version 4.5.2

101 Changes to address a potential race condition when route tables
102 arrive in quick succession. (RIC-674)
104 2020 October 30; Version 4.3.1
105 Changes to address code analyser scans and two bug fixes identified
106 while addressing the analysis data. (RIC-673)

117 2020 August 4; Version 4.2.2
118 Correct bug in the rmr_probe support utility when -r option is used
119 on the command line (RIC-644)
121 2020 August 4; Version 4.2.1
122 Add additional environment variable dump if RMR_LOG_VLEVEL set to
125 2020 August 3; Version 4.2.0
126 Add support for the RMR_RTREQ_FREQ environment variable to control
127 the request frequency for a new route table (default 5s if not
130 2020 July 21; Version 4.1.4
131 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
133 2020 July 9; version 4.1.3
134 Allow RTS messages to be sent before the arrival of the initial
135 route table. Calls to RTS (heart beat responses) prior to the
136 initial route table load could cause a crash if a framework
137 blindly assumes that RTS is valid. (RIC-589)
139 2020 June 22; version 4.1.2
140 Fix typo in RIC Message header file.
142 Add document for message type constants and the scripts

173 2020 April 22; version 4.0.1
174 Correct message type constant for Traffic Steering predication (RIC-342)
176 2020 April 21; version 4.0.0
177 The NNG based libraries are no longer included in the RMR packages.
178 This is considered a breaking change as NNG will not be supported by
179 default. It is still possible to build with RMR-NNG libraries, but
180 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
181 Upgrading to 4.0.0 only means that the underlying transport mechanism
182 is limited only to SI95.
184 The rmr_rcv_specific() function has been deprecated as it was necessary
185 only for NNG and Nanomsg support. Its use should be discontinued.
187 2020 April 20; version 3.8.2
188 Fix bug which was preventing an instance receiving dynamic route
189 table updates. (RIC-336)
191 2020 April 20; version 3.8.1

194 2020 April 17; version 3.8.0
195 Add safe connect to avoid potential connect bug on Linux (RIC-332)
197 Change debugging in route table collector to avoid possible
198 segment fault when in level 2 debug (RIC-335)
200 2020 April 15; version 3.7.4
201 Add missing message type to header file (RIC-334)
203 2020 April 14; version 3.7.3

206 2020 April 10; version 3.7.2
207 Fix bug related to static route table only mode (RIC-331)
209 2020 April 9; version 3.7.1
210 The max length restriction for receiving messages when using SI95 has
211 been removed. The length supplied during initialisation is used as
212 the "normal maximum" and default buffer allocation size, but messages
213 arriving which are larger are accepted. (RIC-309)
215 2020 April 7; version 3.7.0
216 The health check support programme was renamed to rmr_probe (RIC-308).
218 2020 April 6; version 3.6.6
219 Correct bug in SI95 address conversion module (RIC-327)
220 Correct bug in SI initialisation module
222 2020 April 2; version 3.6.5

224 use as a listen target (RIC-307)
226 2020 April 1; version 3.6.4
227 Correct potential nil pointer use in the NNG interface (RIC-303)
228 Correct issue preventing CI build without a container
230 2020 March 30; version 3.6.3
231 Correct the max receive message size constant in rmr.h (RIC-301)
233 2020 March 23; version 3.6.2

245 ack/nack of meid tables (RIC-273)
247 2020 March 10; version 3.5.1
248 Add missing health check message types.
250 2020 March 9; version 3.5.0
251 Added new wormhole send function: rmr_wh_call().
253 2020 March 6; version 3.4.0
254 Add new wormhole state function: rmr_wh_state().
256 2020 March 5; Version 3.3.1

275 Fix receive thread related core dump (ring early unlock).
277 2020 February 19; version 3.2.1
278 Added missing message types (E2-Setup)
280 2020 February 18; version 3.2.0

282 a request for table update.
284 2020 February 14; version 3.1.3
285 Fix bug in SIsend which was causing a core dump in some cases
286 where the application attempted to send on a connection that
287 had disconnected. (RIC-207).

314 Enable support for dynamic route table updates via RMR session.
316 2020 January 16; version 3.0.0
317 Introduce support for SI95 transport library to replace NNG.
318 (RMR library versions will use leading odd numbers to avoid tag collisions
319 with the wrapper tags which will use even numbers.)
321 2019 December 9; version 1.13.1
322 Correct documentation and missing rel-notes update for RTD.
324 2019 December 6; version 1.13.0

332 2019 November 13; version 1.12.1
333 New message type constants added to support A1.
335 2019 November 4; version 1.11.0
336 Version bump to move away from the 1.10.* to distinguish between
337 release A and the trial.
339 2019 November 7; version 1.12.0
340 Version cut to support continued development for next release
341 preserving the 1.11.* versions for release 1 (Amber) and
344 2019 October 31; version 1.10.2
345 Provide the means to increase the payload size of a received message
346 without losing the data needed to use the rmr_rts_msg() funciton.
348 2019 October 21; version 1.10.1
349 Fix to prevent null message buffer from being returned by the timeout
350 receive function if the function is passed one to reuse.
352 2019 October 21; version 1.10.1
353 Add periodic dump of send count info to stderr.
355 2019 September 27; version 1.9.0
356 Python bindings added receive all queued function and corrected a unit test
358 2019 September 25; version 1.8.3
359 Correct application level test issue causing timing problems during
360 jenkins verification testing at command and merge
362 Handle the NNG connection shutdown status which may now be
363 generated when a connection throug a proxy is reset.
365 2019 September 25; version 1.8.2
366 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
368 2019 September 19; version 1.8.1
369 Correct missing constant for wrappers.
371 2019 September 19; version 1.8.0
372 New message types added:
373 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
375 2019 September 17; version 1.7.0
376 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
377 in the environment before rmr_init() is invoked to revert to
378 synchronous first TCP connections. (Recovery connection attempts
379 have always been asynchronous).
381 2019 September 3; version 1.6.0
382 Fix bug in the rmr_rts_msg() function. If a return to sender message
383 failed, the source IP address was not correctly adjusted and could
384 cause the message to be "reflected" back to the sender on a retry.
386 Added the ability to set the source "ID" via an environment var
387 (RMR_SRC_ID). When present in the environment, the string will
388 be placed in to the message header as the source and thus be used
389 by an application calling rmr_rts_smg() to return a response to
390 the sender. If this environment variable is not present, the host
391 name (original behaviour) is used.
393 2019 August 26; version 1.4.0
394 New message types were added.
396 2019 August 16; version 1.3.0
397 New mesage types added.
399 2019 August 13; version 1.2.0 (API change, non-breaking)
400 The function rmr_get_xact() was added to proide a convenient
401 way to extract the transaction field from a message.
403 2019 August 8; version 1.1.0 (API change)
404 This change should be backward compatable/non-breaking
405 A new field has been added to the message buffer (rmr_mbuf_t).
406 This field (tp_state) is used to communicate the errno value
407 that the transport mechanism might set during send and/or
408 receive operations. C programmes should continue to use
409 errno directly, but in some environments wrappers may not be
410 able to access errno and this provides the value to them.
411 See the rmr_alloc_msg manual page for more details.
413 2019 August 6; version 1.0.45 (build changes)
414 Support for the Nanomsg transport library has been dropped.
415 The library librmr.* will no longer be included in packages.
417 Packages will install RMR libraries into the system preferred
418 target directory. On some systems this is /usr/local/lib
419 and on others it is /usr/local/lib64. The diretory is
420 determined by the sytem on which the package is built and
421 NOT by the system installing the package, so it's possible
422 that the RMR libraries end up in a strange location if the
423 .deb or .rpm file was generated on a Linux flavour that
424 has a different preference than the one where the package
427 2019 August 6; version 1.0.44 (API change)
428 Added a new message type constant.
430 2019 July 15; Version 1.0.39 (bug fix)
431 Prevent unnecessary usleep in retry loop.
433 2019 July 12; Version 1.0.38 (API change)
434 Added new message types to RIC_message_types.h.
436 2019 July 11; Version 1.0.37
438 librmr and librmr_nng
439 - Add message buffer API function rmr_trace_ref()
440 (see rmr_trace_ref.3 manual page in dev package).
