64 the request frequency for a new route table (default 5s if not
67 2020 July 21; Version 4.1.4

70 2020 July 9; version 4.1.3
71 Allow RTS messages to be sent before the arrival of the initial
72 route table. Calls to RTS (heart beat responses) prior to the
73 initial route table load could cause a crash if a framework
74 blindly assumes that RTS is valid. (RIC-589)
76 2020 June 22; version 4.1.2
77 Fix typo in RIC Message header file.
79 Add document for message type constants and the scripts

98 Fix the bug in SI95 receive message management semaphore count
101 2020 April 29; version 4.0.4

107 2020 April 24; version 4.0.2
108 Correct bug in SI95 transport header length validation (RIC-341)
110 2020 April 22; version 4.0.1
111 Correct message type constant for Traffic Steering predication (RIC-342)
113 2020 April 21; version 4.0.0
114 The NNG based libraries are no longer included in the RMR packages.
115 This is considered a breaking change as NNG will not be supported by
116 default. It is still possible to build with RMR-NNG libraries, but
117 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
118 Upgrading to 4.0.0 only means that the underlying transport mechanism
119 is limited only to SI95.
121 The rmr_rcv_specific() function has been deprecated as it was necessary
122 only for NNG and Nanomsg support. Its use should be discontinued.
124 2020 April 20; version 3.8.2
125 Fix bug which was preventing an instance receiving dynamic route
126 table updates. (RIC-336)
128 2020 April 20; version 3.8.1

134 Change debugging in route table collector to avoid possible
135 segment fault when in level 2 debug (RIC-335)
137 2020 April 15; version 3.7.4
138 Add missing message type to header file (RIC-334)
140 2020 April 14; version 3.7.3

143 2020 April 10; version 3.7.2
144 Fix bug related to static route table only mode (RIC-331)
146 2020 April 9; version 3.7.1
147 The max length restriction for receiving messages when using SI95 has
148 been removed. The length supplied during initialisation is used as
149 the "normal maximum" and default buffer allocation size, but messages
150 arriving which are larger are accepted. (RIC-309)
152 2020 April 7; version 3.7.0
153 The health check support programme was renamed to rmr_probe (RIC-308).
155 2020 April 6; version 3.6.6
156 Correct bug in SI95 address conversion module (RIC-327)
157 Correct bug in SI initialisation module
159 2020 April 2; version 3.6.5

182 ack/nack of meid tables (RIC-273)

185 Add missing health check message types.
187 2020 March 9; version 3.5.0

219 a request for table update.
221 2020 February 14; version 3.1.3
222 Fix bug in SIsend which was causing a core dump in some cases

253 2020 January 16; version 3.0.0
254 Introduce support for SI95 transport library to replace NNG.
255 (RMR library versions will use leading odd numbers to avoid tag collisions
256 with the wrapper tags which will use even numbers.)
258 2019 December 9; version 1.13.1
259 Correct documentation and missing rel-notes update for RTD.
261 2019 December 6; version 1.13.0

272 2019 November 4; version 1.11.0

281 2019 October 31; version 1.10.2
282 Provide the means to increase the payload size of a received message
283 without losing the data needed to use the rmr_rts_msg() funciton.
285 2019 October 21; version 1.10.1
286 Fix to prevent null message buffer from being returned by the timeout
287 receive function if the function is passed one to reuse.
289 2019 October 21; version 1.10.1
290 Add periodic dump of send count info to stderr.
292 2019 September 27; version 1.9.0
293 Python bindings added receive all queued function and corrected a unit test
295 2019 September 25; version 1.8.3
296 Correct application level test issue causing timing problems during
297 jenkins verification testing at command and merge
299 Handle the NNG connection shutdown status which may now be

302 2019 September 25; version 1.8.2
303 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
305 2019 September 19; version 1.8.1
306 Correct missing constant for wrappers.
308 2019 September 19; version 1.8.0
309 New message types added:
310 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
312 2019 September 17; version 1.7.0
313 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
314 in the environment before rmr_init() is invoked to revert to
315 synchronous first TCP connections. (Recovery connection attempts
316 have always been asynchronous).
318 2019 September 3; version 1.6.0
319 Fix bug in the rmr_rts_msg() function. If a return to sender message
320 failed, the source IP address was not correctly adjusted and could
321 cause the message to be "reflected" back to the sender on a retry.
323 Added the ability to set the source "ID" via an environment var
324 (RMR_SRC_ID). When present in the environment, the string will
325 be placed in to the message header as the source and thus be used
326 by an application calling rmr_rts_smg() to return a response to
327 the sender. If this environment variable is not present, the host
328 name (original behaviour) is used.
330 2019 August 26; version 1.4.0
331 New message types were added.
333 2019 August 16; version 1.3.0
334 New mesage types added.
336 2019 August 13; version 1.2.0 (API change, non-breaking)
337 The function rmr_get_xact() was added to proide a convenient
338 way to extract the transaction field from a message.
340 2019 August 8; version 1.1.0 (API change)
341 This change should be backward compatable/non-breaking
342 A new field has been added to the message buffer (rmr_mbuf_t).
343 This field (tp_state) is used to communicate the errno value
344 that the transport mechanism might set during send and/or
345 receive operations. C programmes should continue to use
346 errno directly, but in some environments wrappers may not be
347 able to access errno and this provides the value to them.
348 See the rmr_alloc_msg manual page for more details.
350 2019 August 6; version 1.0.45 (build changes)
351 Support for the Nanomsg transport library has been dropped.
352 The library librmr.* will no longer be included in packages.
354 Packages will install RMR libraries into the system preferred
355 target directory. On some systems this is /usr/local/lib
356 and on others it is /usr/local/lib64. The diretory is
357 determined by the sytem on which the package is built and
358 NOT by the system installing the package, so it's possible
359 that the RMR libraries end up in a strange location if the
360 .deb or .rpm file was generated on a Linux flavour that
361 has a different preference than the one where the package
364 2019 August 6; version 1.0.44 (API change)
365 Added a new message type constant.
367 2019 July 15; Version 1.0.39 (bug fix)
368 Prevent unnecessary usleep in retry loop.
370 2019 July 12; Version 1.0.38 (API change)
371 Added new message types to RIC_message_types.h.
373 2019 July 11; Version 1.0.37
375 librmr and librmr_nng
376 - Add message buffer API function rmr_trace_ref()
377 (see rmr_trace_ref.3 manual page in dev package).
