8 2021 December 2; version 4.8.0
9 Fixing memory leak in python support function (RIC-858).
10 New API added for debugging rmr rx queue (RIC-838).
12 2021 April 22; version 4.7.4
13 Beef up unit testing in SI package and fix a few static analysis
16 2021 April 19; version 4.7.3
17 Correct flag check bug in route table functions (RIC-777).
19 2021 April 9; version 4.7.2
20 Ensure that route table update received from route generator is not
21 applied before a full route table is received.
23 2021 April 2; version 4.7.1
24 Correct issues found during static code analysis.
26 2021 March 31; version 4.7.0
27 The route table collector thread will capture the current "offering"
28 from the Route Manager (table generator) if the RMR_SEED_RT environment
31 2021 March 10; version 4.6.1
32 Corrected unit test "framework" to make manual testing easier, and to
33 add the ability to set the code optimisation level via the CMake
34 command line parameter OPT_LEVEL=n.
36 2021 February 22; Version 4.6.0
37 Enhanced to use millisecond based timestamps when writing log messages.
40 Enhanced to eliminate the reqirement that the file specified by the
41 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
42 will correctly find this file if it is created after initialisation.
43 Further, if the environment variable is not given, the user may create
44 and populate /tmp/rmr.v at any time and the contents of this file will
45 be used as if it were supplied via the environment variable. This should
46 make debugging in existing containers easier.
48 Enhanced to send an alarm manager when the user application is not
49 receiving messages fast enough. The original messages written to
50 the standard error are still generated. (RIC-204)
52 2021 January 21; Version 4.5.2
53 Fixes the excessive TCP session bug when sending to a slow receiver
54 and a related segment fault because of too many open file descriptors.

62 Version bump for next release tracking.
63 Corrected a potential locking issue in message allocation. (RIC-732)
65 2020 December 4; Version 4.4.6

86 2020 November 4; Version 4.4.0
87 Changes to address a potential race condition when route tables
88 arrive in quick succession. (RIC-674)
90 2020 October 30; Version 4.3.1
91 Changes to address code analyser scans and two bug fixes identified
92 while addressing the analysis data. (RIC-673)

103 2020 August 4; Version 4.2.2
104 Correct bug in the rmr_probe support utility when -r option is used
105 on the command line (RIC-644)
107 2020 August 4; Version 4.2.1
108 Add additional environment variable dump if RMR_LOG_VLEVEL set to
111 2020 August 3; Version 4.2.0
112 Add support for the RMR_RTREQ_FREQ environment variable to control
113 the request frequency for a new route table (default 5s if not
116 2020 July 21; Version 4.1.4
117 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
119 2020 July 9; version 4.1.3
120 Allow RTS messages to be sent before the arrival of the initial
121 route table. Calls to RTS (heart beat responses) prior to the
122 initial route table load could cause a crash if a framework
123 blindly assumes that RTS is valid. (RIC-589)
125 2020 June 22; version 4.1.2
126 Fix typo in RIC Message header file.
128 Add document for message type constants and the scripts

139 2020 June 18; version 4.1.0
140 Bump version minor to move away from 4.0.* which will bump for any
141 patches applied back to bronze.
143 Add magic C++ goo to symtab header file allowing C++ xAPPs to use
144 the symbol table directly.
146 2020 May 06; version 4.0.5

159 2020 April 22; version 4.0.1
160 Correct message type constant for Traffic Steering predication (RIC-342)
162 2020 April 21; version 4.0.0
163 The NNG based libraries are no longer included in the RMR packages.
164 This is considered a breaking change as NNG will not be supported by
165 default. It is still possible to build with RMR-NNG libraries, but
166 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
167 Upgrading to 4.0.0 only means that the underlying transport mechanism
168 is limited only to SI95.
170 The rmr_rcv_specific() function has been deprecated as it was necessary
171 only for NNG and Nanomsg support. Its use should be discontinued.
173 2020 April 20; version 3.8.2

175 table updates. (RIC-336)
177 2020 April 20; version 3.8.1

183 Change debugging in route table collector to avoid possible
184 segment fault when in level 2 debug (RIC-335)
186 2020 April 15; version 3.7.4
187 Add missing message type to header file (RIC-334)
189 2020 April 14; version 3.7.3

192 2020 April 10; version 3.7.2
193 Fix bug related to static route table only mode (RIC-331)
195 2020 April 9; version 3.7.1
196 The max length restriction for receiving messages when using SI95 has
197 been removed. The length supplied during initialisation is used as
198 the "normal maximum" and default buffer allocation size, but messages
199 arriving which are larger are accepted. (RIC-309)
201 2020 April 7; version 3.7.0
202 The health check support programme was renamed to rmr_probe (RIC-308).
204 2020 April 6; version 3.6.6
205 Correct bug in SI95 address conversion module (RIC-327)
206 Correct bug in SI initialisation module
208 2020 April 2; version 3.6.5

210 use as a listen target (RIC-307)
212 2020 April 1; version 3.6.4
213 Correct potential nil pointer use in the NNG interface (RIC-303)
214 Correct issue preventing CI build without a container
216 2020 March 30; version 3.6.3

231 ack/nack of meid tables (RIC-273)
233 2020 March 10; version 3.5.1
234 Add missing health check message types.
236 2020 March 9; version 3.5.0

302 2020 January 16; version 3.0.0
303 Introduce support for SI95 transport library to replace NNG.
304 (RMR library versions will use leading odd numbers to avoid tag collisions
305 with the wrapper tags which will use even numbers.)
307 2019 December 9; version 1.13.1
308 Correct documentation and missing rel-notes update for RTD.
310 2019 December 6; version 1.13.0

316 was not always copied.
318 2019 November 13; version 1.12.1
319 New message type constants added to support A1.
321 2019 November 4; version 1.11.0
322 Version bump to move away from the 1.10.* to distinguish between
323 release A and the trial.
325 2019 November 7; version 1.12.0
326 Version cut to support continued development for next release
327 preserving the 1.11.* versions for release 1 (Amber) and
330 2019 October 31; version 1.10.2
331 Provide the means to increase the payload size of a received message
332 without losing the data needed to use the rmr_rts_msg() funciton.
334 2019 October 21; version 1.10.1
335 Fix to prevent null message buffer from being returned by the timeout
336 receive function if the function is passed one to reuse.
338 2019 October 21; version 1.10.1
339 Add periodic dump of send count info to stderr.
341 2019 September 27; version 1.9.0
342 Python bindings added receive all queued function and corrected a unit test
344 2019 September 25; version 1.8.3
345 Correct application level test issue causing timing problems during
346 jenkins verification testing at command and merge
348 Handle the NNG connection shutdown status which may now be
349 generated when a connection throug a proxy is reset.
351 2019 September 25; version 1.8.2
352 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
354 2019 September 19; version 1.8.1
355 Correct missing constant for wrappers.
357 2019 September 19; version 1.8.0
358 New message types added:
359 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
361 2019 September 17; version 1.7.0
362 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
363 in the environment before rmr_init() is invoked to revert to
364 synchronous first TCP connections. (Recovery connection attempts
365 have always been asynchronous).
367 2019 September 3; version 1.6.0
368 Fix bug in the rmr_rts_msg() function. If a return to sender message
369 failed, the source IP address was not correctly adjusted and could
370 cause the message to be "reflected" back to the sender on a retry.
372 Added the ability to set the source "ID" via an environment var
373 (RMR_SRC_ID). When present in the environment, the string will
374 be placed in to the message header as the source and thus be used
375 by an application calling rmr_rts_smg() to return a response to
376 the sender. If this environment variable is not present, the host
377 name (original behaviour) is used.
379 2019 August 26; version 1.4.0
380 New message types were added.
382 2019 August 16; version 1.3.0
383 New mesage types added.
385 2019 August 13; version 1.2.0 (API change, non-breaking)
386 The function rmr_get_xact() was added to proide a convenient
387 way to extract the transaction field from a message.
389 2019 August 8; version 1.1.0 (API change)
390 This change should be backward compatable/non-breaking
391 A new field has been added to the message buffer (rmr_mbuf_t).
392 This field (tp_state) is used to communicate the errno value
393 that the transport mechanism might set during send and/or
394 receive operations. C programmes should continue to use
395 errno directly, but in some environments wrappers may not be
396 able to access errno and this provides the value to them.
397 See the rmr_alloc_msg manual page for more details.
399 2019 August 6; version 1.0.45 (build changes)
400 Support for the Nanomsg transport library has been dropped.
401 The library librmr.* will no longer be included in packages.
403 Packages will install RMR libraries into the system preferred
404 target directory. On some systems this is /usr/local/lib
405 and on others it is /usr/local/lib64. The diretory is
406 determined by the sytem on which the package is built and
407 NOT by the system installing the package, so it's possible
408 that the RMR libraries end up in a strange location if the
409 .deb or .rpm file was generated on a Linux flavour that
410 has a different preference than the one where the package
413 2019 August 6; version 1.0.44 (API change)
414 Added a new message type constant.
416 2019 July 15; Version 1.0.39 (bug fix)
417 Prevent unnecessary usleep in retry loop.
419 2019 July 12; Version 1.0.38 (API change)
420 Added new message types to RIC_message_types.h.
422 2019 July 11; Version 1.0.37
424 librmr and librmr_nng
425 - Add message buffer API function rmr_trace_ref()
426 (see rmr_trace_ref.3 manual page in dev package).
