26 Fixes some bugs and possible memory likeage in SI95 code.
28 2021 December 2; version 4.8.0
29 Fixing memory leak in python support function (RIC-858).
30 New API added for debugging rmr rx queue (RIC-838).

33 Beef up unit testing in SI package and fix a few static analysis
36 2021 April 19; version 4.7.3
37 Correct flag check bug in route table functions (RIC-777).
39 2021 April 9; version 4.7.2
40 Ensure that route table update received from route generator is not
41 applied before a full route table is received.
43 2021 April 2; version 4.7.1
44 Correct issues found during static code analysis.
46 2021 March 31; version 4.7.0
47 The route table collector thread will capture the current "offering"
48 from the Route Manager (table generator) if the RMR_SEED_RT environment
51 2021 March 10; version 4.6.1
52 Corrected unit test "framework" to make manual testing easier, and to
53 add the ability to set the code optimisation level via the CMake
54 command line parameter OPT_LEVEL=n.
56 2021 February 22; Version 4.6.0
57 Enhanced to use millisecond based timestamps when writing log messages.
60 Enhanced to eliminate the reqirement that the file specified by the
61 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
62 will correctly find this file if it is created after initialisation.
63 Further, if the environment variable is not given, the user may create
64 and populate /tmp/rmr.v at any time and the contents of this file will
65 be used as if it were supplied via the environment variable. This should
66 make debugging in existing containers easier.
68 Enhanced to send an alarm manager when the user application is not
69 receiving messages fast enough. The original messages written to
70 the standard error are still generated. (RIC-204)
72 2021 January 21; Version 4.5.2

123 2020 August 4; Version 4.2.2
124 Correct bug in the rmr_probe support utility when -r option is used
125 on the command line (RIC-644)
127 2020 August 4; Version 4.2.1
128 Add additional environment variable dump if RMR_LOG_VLEVEL set to
131 2020 August 3; Version 4.2.0
132 Add support for the RMR_RTREQ_FREQ environment variable to control
133 the request frequency for a new route table (default 5s if not
136 2020 July 21; Version 4.1.4
137 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
139 2020 July 9; version 4.1.3
140 Allow RTS messages to be sent before the arrival of the initial
141 route table. Calls to RTS (heart beat responses) prior to the
142 initial route table load could cause a crash if a framework
143 blindly assumes that RTS is valid. (RIC-589)
145 2020 June 22; version 4.1.2
146 Fix typo in RIC Message header file.
148 Add document for message type constants and the scripts

180 Correct message type constant for Traffic Steering predication (RIC-342)
182 2020 April 21; version 4.0.0
183 The NNG based libraries are no longer included in the RMR packages.
184 This is considered a breaking change as NNG will not be supported by
185 default. It is still possible to build with RMR-NNG libraries, but
186 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
187 Upgrading to 4.0.0 only means that the underlying transport mechanism
188 is limited only to SI95.
190 The rmr_rcv_specific() function has been deprecated as it was necessary
191 only for NNG and Nanomsg support. Its use should be discontinued.
193 2020 April 20; version 3.8.2

195 table updates. (RIC-336)
197 2020 April 20; version 3.8.1

203 Change debugging in route table collector to avoid possible
204 segment fault when in level 2 debug (RIC-335)
206 2020 April 15; version 3.7.4
207 Add missing message type to header file (RIC-334)
209 2020 April 14; version 3.7.3

212 2020 April 10; version 3.7.2
213 Fix bug related to static route table only mode (RIC-331)
215 2020 April 9; version 3.7.1
216 The max length restriction for receiving messages when using SI95 has
217 been removed. The length supplied during initialisation is used as
218 the "normal maximum" and default buffer allocation size, but messages
219 arriving which are larger are accepted. (RIC-309)
221 2020 April 7; version 3.7.0
222 The health check support programme was renamed to rmr_probe (RIC-308).
224 2020 April 6; version 3.6.6
225 Correct bug in SI95 address conversion module (RIC-327)
226 Correct bug in SI initialisation module
228 2020 April 2; version 3.6.5

230 use as a listen target (RIC-307)
232 2020 April 1; version 3.6.4
233 Correct potential nil pointer use in the NNG interface (RIC-303)
234 Correct issue preventing CI build without a container
236 2020 March 30; version 3.6.3
237 Correct the max receive message size constant in rmr.h (RIC-301)
239 2020 March 23; version 3.6.2

251 ack/nack of meid tables (RIC-273)
253 2020 March 10; version 3.5.1
254 Add missing health check message types.
256 2020 March 9; version 3.5.0

322 2020 January 16; version 3.0.0
323 Introduce support for SI95 transport library to replace NNG.
324 (RMR library versions will use leading odd numbers to avoid tag collisions
325 with the wrapper tags which will use even numbers.)
327 2019 December 9; version 1.13.1
328 Correct documentation and missing rel-notes update for RTD.
330 2019 December 6; version 1.13.0

336 was not always copied.
338 2019 November 13; version 1.12.1
339 New message type constants added to support A1.
341 2019 November 4; version 1.11.0
342 Version bump to move away from the 1.10.* to distinguish between
343 release A and the trial.
345 2019 November 7; version 1.12.0
346 Version cut to support continued development for next release
347 preserving the 1.11.* versions for release 1 (Amber) and
350 2019 October 31; version 1.10.2
351 Provide the means to increase the payload size of a received message
352 without losing the data needed to use the rmr_rts_msg() funciton.
354 2019 October 21; version 1.10.1
355 Fix to prevent null message buffer from being returned by the timeout
356 receive function if the function is passed one to reuse.
358 2019 October 21; version 1.10.1
359 Add periodic dump of send count info to stderr.
361 2019 September 27; version 1.9.0
362 Python bindings added receive all queued function and corrected a unit test
364 2019 September 25; version 1.8.3
365 Correct application level test issue causing timing problems during
366 jenkins verification testing at command and merge
368 Handle the NNG connection shutdown status which may now be
369 generated when a connection throug a proxy is reset.
371 2019 September 25; version 1.8.2
372 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
374 2019 September 19; version 1.8.1
375 Correct missing constant for wrappers.
377 2019 September 19; version 1.8.0
378 New message types added:
379 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
381 2019 September 17; version 1.7.0
382 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
383 in the environment before rmr_init() is invoked to revert to
384 synchronous first TCP connections. (Recovery connection attempts
385 have always been asynchronous).
387 2019 September 3; version 1.6.0
388 Fix bug in the rmr_rts_msg() function. If a return to sender message
389 failed, the source IP address was not correctly adjusted and could
390 cause the message to be "reflected" back to the sender on a retry.
392 Added the ability to set the source "ID" via an environment var
393 (RMR_SRC_ID). When present in the environment, the string will
394 be placed in to the message header as the source and thus be used
395 by an application calling rmr_rts_smg() to return a response to
396 the sender. If this environment variable is not present, the host
397 name (original behaviour) is used.
399 2019 August 26; version 1.4.0
400 New message types were added.
402 2019 August 16; version 1.3.0
403 New mesage types added.
405 2019 August 13; version 1.2.0 (API change, non-breaking)
406 The function rmr_get_xact() was added to proide a convenient
407 way to extract the transaction field from a message.
409 2019 August 8; version 1.1.0 (API change)
410 This change should be backward compatable/non-breaking
411 A new field has been added to the message buffer (rmr_mbuf_t).
412 This field (tp_state) is used to communicate the errno value
413 that the transport mechanism might set during send and/or
414 receive operations. C programmes should continue to use
415 errno directly, but in some environments wrappers may not be
416 able to access errno and this provides the value to them.
417 See the rmr_alloc_msg manual page for more details.
419 2019 August 6; version 1.0.45 (build changes)
420 Support for the Nanomsg transport library has been dropped.
421 The library librmr.* will no longer be included in packages.
423 Packages will install RMR libraries into the system preferred
424 target directory. On some systems this is /usr/local/lib
425 and on others it is /usr/local/lib64. The diretory is
426 determined by the sytem on which the package is built and
427 NOT by the system installing the package, so it's possible
428 that the RMR libraries end up in a strange location if the
429 .deb or .rpm file was generated on a Linux flavour that
430 has a different preference than the one where the package
433 2019 August 6; version 1.0.44 (API change)
434 Added a new message type constant.
436 2019 July 15; Version 1.0.39 (bug fix)
437 Prevent unnecessary usleep in retry loop.
439 2019 July 12; Version 1.0.38 (API change)
440 Added new message types to RIC_message_types.h.
442 2019 July 11; Version 1.0.37
444 librmr and librmr_nng
445 - Add message buffer API function rmr_trace_ref()
446 (see rmr_trace_ref.3 manual page in dev package).
