8 2021 April 22; version 4.7.4
9 Beef up unit testing in SI package and fix a few static analysis
12 2021 April 19; version 4.7.3
13 Correct flag check bug in route table functions (RIC-777).
15 2021 April 9; version 4.7.2
16 Ensure that route table update received from route generator is not
17 applied before a full route table is received.
19 2021 April 2; version 4.7.1
20 Correct issues found during static code analysis.
22 2021 March 31; version 4.7.0
23 The route table collector thread will capture the current "offering"
24 from the Route Manager (table generator) if the RMR_SEED_RT environment
27 2021 March 10; version 4.6.1
28 Corrected unit test "framework" to make manual testing easier, and to
29 add the ability to set the code optimisation level via the CMake
30 command line parameter OPT_LEVEL=n.
32 2021 February 22; Version 4.6.0
33 Enhanced to use millisecond based timestamps when writing log messages.
36 Enhanced to eliminate the reqirement that the file specified by the
37 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
38 will correctly find this file if it is created after initialisation.
39 Further, if the environment variable is not given, the user may create
40 and populate /tmp/rmr.v at any time and the contents of this file will
41 be used as if it were supplied via the environment variable. This should
42 make debugging in existing containers easier.
44 Enhanced to send an alarm manager when the user application is not
45 receiving messages fast enough. The original messages written to
46 the standard error are still generated. (RIC-204)
48 2021 January 21; Version 4.5.2
49 Fixes the excessive TCP session bug when sending to a slow receiver
50 and a related segment fault because of too many open file descriptors.
53 2021 January 19; Version 4.5.1
54 Version bump to work round a CI job bug preventing push of the 4.5.0
55 packages from staging to release in package cloud. (RIC-732)
57 2021 January 8; Version 4.5.0
58 Version bump for next release tracking.
59 Corrected a potential locking issue in message allocation. (RIC-732)
61 2020 December 4; Version 4.4.6

82 2020 November 4; Version 4.4.0
83 Changes to address a potential race condition when route tables
84 arrive in quick succession. (RIC-674)
86 2020 October 30; Version 4.3.1
87 Changes to address code analyser scans and two bug fixes identified
88 while addressing the analysis data. (RIC-673)

91 Add message types for traffic steering anomaly messages
93 2020 September 15; Version 4.2.4
94 Add man page for the rmr_set_low_latency() function (RIC-631)
96 2020 September 15; Version 4.2.3

99 2020 August 4; Version 4.2.2
100 Correct bug in the rmr_probe support utility when -r option is used
101 on the command line (RIC-644)
103 2020 August 4; Version 4.2.1
104 Add additional environment variable dump if RMR_LOG_VLEVEL set to
107 2020 August 3; Version 4.2.0
108 Add support for the RMR_RTREQ_FREQ environment variable to control
109 the request frequency for a new route table (default 5s if not
112 2020 July 21; Version 4.1.4
113 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
115 2020 July 9; version 4.1.3
116 Allow RTS messages to be sent before the arrival of the initial
117 route table. Calls to RTS (heart beat responses) prior to the
118 initial route table load could cause a crash if a framework
119 blindly assumes that RTS is valid. (RIC-589)
121 2020 June 22; version 4.1.2
122 Fix typo in RIC Message header file.
124 Add document for message type constants and the scripts
127 2020 June 22; version 4.1.1

133 RAN_E2_RESET_RESP (12009)
135 2020 June 18; version 4.1.0
136 Bump version minor to move away from 4.0.* which will bump for any
137 patches applied back to bronze.
139 Add magic C++ goo to symtab header file allowing C++ xAPPs to use
140 the symbol table directly.
142 2020 May 06; version 4.0.5
143 Fix the bug in SI95 receive message management semaphore count
146 2020 April 29; version 4.0.4

152 2020 April 24; version 4.0.2
153 Correct bug in SI95 transport header length validation (RIC-341)
155 2020 April 22; version 4.0.1
156 Correct message type constant for Traffic Steering predication (RIC-342)
158 2020 April 21; version 4.0.0
159 The NNG based libraries are no longer included in the RMR packages.
160 This is considered a breaking change as NNG will not be supported by
161 default. It is still possible to build with RMR-NNG libraries, but
162 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
163 Upgrading to 4.0.0 only means that the underlying transport mechanism
164 is limited only to SI95.
166 The rmr_rcv_specific() function has been deprecated as it was necessary
167 only for NNG and Nanomsg support. Its use should be discontinued.
169 2020 April 20; version 3.8.2
170 Fix bug which was preventing an instance receiving dynamic route
171 table updates. (RIC-336)
173 2020 April 20; version 3.8.1

179 Change debugging in route table collector to avoid possible
180 segment fault when in level 2 debug (RIC-335)
182 2020 April 15; version 3.7.4
183 Add missing message type to header file (RIC-334)
185 2020 April 14; version 3.7.3

188 2020 April 10; version 3.7.2
189 Fix bug related to static route table only mode (RIC-331)
191 2020 April 9; version 3.7.1
192 The max length restriction for receiving messages when using SI95 has
193 been removed. The length supplied during initialisation is used as
194 the "normal maximum" and default buffer allocation size, but messages
195 arriving which are larger are accepted. (RIC-309)
197 2020 April 7; version 3.7.0
198 The health check support programme was renamed to rmr_probe (RIC-308).
200 2020 April 6; version 3.6.6
201 Correct bug in SI95 address conversion module (RIC-327)
202 Correct bug in SI initialisation module
204 2020 April 2; version 3.6.5

206 use as a listen target (RIC-307)
208 2020 April 1; version 3.6.4
209 Correct potential nil pointer use in the NNG interface (RIC-303)
210 Correct issue preventing CI build without a container
212 2020 March 30; version 3.6.3

227 ack/nack of meid tables (RIC-273)
229 2020 March 10; version 3.5.1
230 Add missing health check message types.
232 2020 March 9; version 3.5.0

264 a request for table update.
266 2020 February 14; version 3.1.3
267 Fix bug in SIsend which was causing a core dump in some cases
268 where the application attempted to send on a connection that
269 had disconnected. (RIC-207).

298 2020 January 16; version 3.0.0
299 Introduce support for SI95 transport library to replace NNG.
300 (RMR library versions will use leading odd numbers to avoid tag collisions
301 with the wrapper tags which will use even numbers.)
303 2019 December 9; version 1.13.1
304 Correct documentation and missing rel-notes update for RTD.
306 2019 December 6; version 1.13.0

312 was not always copied.
314 2019 November 13; version 1.12.1
315 New message type constants added to support A1.
317 2019 November 4; version 1.11.0
318 Version bump to move away from the 1.10.* to distinguish between

321 2019 November 7; version 1.12.0
322 Version cut to support continued development for next release
323 preserving the 1.11.* versions for release 1 (Amber) and
326 2019 October 31; version 1.10.2
327 Provide the means to increase the payload size of a received message
328 without losing the data needed to use the rmr_rts_msg() funciton.
330 2019 October 21; version 1.10.1
331 Fix to prevent null message buffer from being returned by the timeout
332 receive function if the function is passed one to reuse.
334 2019 October 21; version 1.10.1
335 Add periodic dump of send count info to stderr.
337 2019 September 27; version 1.9.0
338 Python bindings added receive all queued function and corrected a unit test
340 2019 September 25; version 1.8.3
341 Correct application level test issue causing timing problems during
342 jenkins verification testing at command and merge
344 Handle the NNG connection shutdown status which may now be
345 generated when a connection throug a proxy is reset.
347 2019 September 25; version 1.8.2
348 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
350 2019 September 19; version 1.8.1
351 Correct missing constant for wrappers.
353 2019 September 19; version 1.8.0
354 New message types added:
355 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
357 2019 September 17; version 1.7.0
358 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
359 in the environment before rmr_init() is invoked to revert to
360 synchronous first TCP connections. (Recovery connection attempts
361 have always been asynchronous).
363 2019 September 3; version 1.6.0
364 Fix bug in the rmr_rts_msg() function. If a return to sender message
365 failed, the source IP address was not correctly adjusted and could
366 cause the message to be "reflected" back to the sender on a retry.
368 Added the ability to set the source "ID" via an environment var
369 (RMR_SRC_ID). When present in the environment, the string will
370 be placed in to the message header as the source and thus be used
371 by an application calling rmr_rts_smg() to return a response to
372 the sender. If this environment variable is not present, the host
373 name (original behaviour) is used.
375 2019 August 26; version 1.4.0
376 New message types were added.
378 2019 August 16; version 1.3.0
379 New mesage types added.
381 2019 August 13; version 1.2.0 (API change, non-breaking)
382 The function rmr_get_xact() was added to proide a convenient
383 way to extract the transaction field from a message.
385 2019 August 8; version 1.1.0 (API change)
386 This change should be backward compatable/non-breaking
387 A new field has been added to the message buffer (rmr_mbuf_t).
388 This field (tp_state) is used to communicate the errno value
389 that the transport mechanism might set during send and/or
390 receive operations. C programmes should continue to use
391 errno directly, but in some environments wrappers may not be
392 able to access errno and this provides the value to them.
393 See the rmr_alloc_msg manual page for more details.
395 2019 August 6; version 1.0.45 (build changes)
396 Support for the Nanomsg transport library has been dropped.
397 The library librmr.* will no longer be included in packages.
399 Packages will install RMR libraries into the system preferred
400 target directory. On some systems this is /usr/local/lib
401 and on others it is /usr/local/lib64. The diretory is
402 determined by the sytem on which the package is built and
403 NOT by the system installing the package, so it's possible
404 that the RMR libraries end up in a strange location if the
405 .deb or .rpm file was generated on a Linux flavour that
406 has a different preference than the one where the package
409 2019 August 6; version 1.0.44 (API change)
410 Added a new message type constant.
412 2019 July 15; Version 1.0.39 (bug fix)
413 Prevent unnecessary usleep in retry loop.
415 2019 July 12; Version 1.0.38 (API change)
416 Added new message types to RIC_message_types.h.
418 2019 July 11; Version 1.0.37
420 librmr and librmr_nng
421 - Add message buffer API function rmr_trace_ref()
422 (see rmr_trace_ref.3 manual page in dev package).
