48 the request frequency for a new route table (default 5s if not
51 2020 July 21; Version 4.1.4
52 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
54 2020 July 9; version 4.1.3
55 Allow RTS messages to be sent before the arrival of the initial
56 route table. Calls to RTS (heart beat responses) prior to the
57 initial route table load could cause a crash if a framework
58 blindly assumes that RTS is valid. (RIC-589)
60 2020 June 22; version 4.1.2
61 Fix typo in RIC Message header file.
63 Add document for message type constants and the scripts
66 2020 June 22; version 4.1.1

75 Bump version minor to move away from 4.0.* which will bump for any
76 patches applied back to bronze.

85 2020 April 29; version 4.0.4

94 2020 April 22; version 4.0.1
95 Correct message type constant for Traffic Steering predication (RIC-342)
97 2020 April 21; version 4.0.0
98 The NNG based libraries are no longer included in the RMR packages.
99 This is considered a breaking change as NNG will not be supported by
100 default. It is still possible to build with RMR-NNG libraries, but
101 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
102 Upgrading to 4.0.0 only means that the underlying transport mechanism
103 is limited only to SI95.
105 The rmr_rcv_specific() function has been deprecated as it was necessary
106 only for NNG and Nanomsg support. Its use should be discontinued.
108 2020 April 20; version 3.8.2
109 Fix bug which was preventing an instance receiving dynamic route
110 table updates. (RIC-336)
112 2020 April 20; version 3.8.1

118 Change debugging in route table collector to avoid possible
119 segment fault when in level 2 debug (RIC-335)
121 2020 April 15; version 3.7.4
122 Add missing message type to header file (RIC-334)

127 2020 April 10; version 3.7.2
128 Fix bug related to static route table only mode (RIC-331)
130 2020 April 9; version 3.7.1
131 The max length restriction for receiving messages when using SI95 has
132 been removed. The length supplied during initialisation is used as
133 the "normal maximum" and default buffer allocation size, but messages
134 arriving which are larger are accepted. (RIC-309)
136 2020 April 7; version 3.7.0
137 The health check support programme was renamed to rmr_probe (RIC-308).
139 2020 April 6; version 3.6.6
140 Correct bug in SI95 address conversion module (RIC-327)
141 Correct bug in SI initialisation module
143 2020 April 2; version 3.6.5

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

169 Add missing health check message types.
171 2020 March 9; version 3.5.0

201 2020 February 18; version 3.2.0

203 a request for table update.
205 2020 February 14; version 3.1.3
206 Fix bug in SIsend which was causing a core dump in some cases

237 2020 January 16; version 3.0.0
238 Introduce support for SI95 transport library to replace NNG.
239 (RMR library versions will use leading odd numbers to avoid tag collisions
240 with the wrapper tags which will use even numbers.)
242 2019 December 9; version 1.13.1
243 Correct documentation and missing rel-notes update for RTD.
245 2019 December 6; version 1.13.0

256 2019 November 4; version 1.11.0

265 2019 October 31; version 1.10.2
266 Provide the means to increase the payload size of a received message
267 without losing the data needed to use the rmr_rts_msg() funciton.
269 2019 October 21; version 1.10.1
270 Fix to prevent null message buffer from being returned by the timeout
271 receive function if the function is passed one to reuse.
273 2019 October 21; version 1.10.1
274 Add periodic dump of send count info to stderr.
276 2019 September 27; version 1.9.0
277 Python bindings added receive all queued function and corrected a unit test
279 2019 September 25; version 1.8.3
280 Correct application level test issue causing timing problems during
281 jenkins verification testing at command and merge
283 Handle the NNG connection shutdown status which may now be

286 2019 September 25; version 1.8.2
287 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
289 2019 September 19; version 1.8.1
290 Correct missing constant for wrappers.
292 2019 September 19; version 1.8.0
293 New message types added:
294 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
296 2019 September 17; version 1.7.0
297 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
298 in the environment before rmr_init() is invoked to revert to
299 synchronous first TCP connections. (Recovery connection attempts
300 have always been asynchronous).
302 2019 September 3; version 1.6.0
303 Fix bug in the rmr_rts_msg() function. If a return to sender message
304 failed, the source IP address was not correctly adjusted and could
305 cause the message to be "reflected" back to the sender on a retry.
307 Added the ability to set the source "ID" via an environment var
308 (RMR_SRC_ID). When present in the environment, the string will
309 be placed in to the message header as the source and thus be used
310 by an application calling rmr_rts_smg() to return a response to
311 the sender. If this environment variable is not present, the host
312 name (original behaviour) is used.
314 2019 August 26; version 1.4.0
315 New message types were added.
317 2019 August 16; version 1.3.0
318 New mesage types added.
320 2019 August 13; version 1.2.0 (API change, non-breaking)
321 The function rmr_get_xact() was added to proide a convenient
322 way to extract the transaction field from a message.
324 2019 August 8; version 1.1.0 (API change)
325 This change should be backward compatable/non-breaking
326 A new field has been added to the message buffer (rmr_mbuf_t).
327 This field (tp_state) is used to communicate the errno value
328 that the transport mechanism might set during send and/or
329 receive operations. C programmes should continue to use
330 errno directly, but in some environments wrappers may not be
331 able to access errno and this provides the value to them.
332 See the rmr_alloc_msg manual page for more details.
334 2019 August 6; version 1.0.45 (build changes)
335 Support for the Nanomsg transport library has been dropped.
336 The library librmr.* will no longer be included in packages.
338 Packages will install RMR libraries into the system preferred
339 target directory. On some systems this is /usr/local/lib
340 and on others it is /usr/local/lib64. The diretory is
341 determined by the sytem on which the package is built and
342 NOT by the system installing the package, so it's possible
343 that the RMR libraries end up in a strange location if the
344 .deb or .rpm file was generated on a Linux flavour that
345 has a different preference than the one where the package
348 2019 August 6; version 1.0.44 (API change)
349 Added a new message type constant.
351 2019 July 15; Version 1.0.39 (bug fix)
352 Prevent unnecessary usleep in retry loop.
354 2019 July 12; Version 1.0.38 (API change)
355 Added new message types to RIC_message_types.h.
357 2019 July 11; Version 1.0.37
359 librmr and librmr_nng
360 - Add message buffer API function rmr_trace_ref()
361 (see rmr_trace_ref.3 manual page in dev package).
