8 2021 March 31; version 4.7.0
9 The route table collector thread will capture the current "offering"
10 from the Route Manager (table generator) if the RMR_SEED_RT environment
13 2021 March 10; version 4.6.1
14 Corrected unit test "framework" to make manual testing easier, and to
15 add the ability to set the code optimisation level via the CMake
16 command line parameter OPT_LEVEL=n.
18 2021 February 22; Version 4.6.0
19 Enhanced to use millisecond based timestamps when writing log messages.
22 Enhanced to eliminate the reqirement that the file specified by the
23 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
24 will correctly find this file if it is created after initialisation.
25 Further, if the environment variable is not given, the user may create
26 and populate /tmp/rmr.v at any time and the contents of this file will
27 be used as if it were supplied via the environment variable. This should
28 make debugging in existing containers easier.
30 Enhanced to send an alarm manager when the user application is not
31 receiving messages fast enough. The original messages written to
32 the standard error are still generated. (RIC-204)
34 2021 January 21; Version 4.5.2
35 Fixes the excessive TCP session bug when sending to a slow receiver
36 and a related segment fault because of too many open file descriptors.

40 Version bump to work round a CI job bug preventing push of the 4.5.0
41 packages from staging to release in package cloud. (RIC-732)
43 2021 January 8; Version 4.5.0
44 Version bump for next release tracking.
45 Corrected a potential locking issue in message allocation. (RIC-732)

56 Correct address memory leak in the RTE cleanup. (RIC-674)
58 2020 November 4; Version 4.4.3
59 Correct bug introduced with race fix (4.4.0) (RIC-674)
61 2020 November 4; Version 4.4.2

68 2020 November 4; Version 4.4.0
69 Changes to address a potential race condition when route tables
70 arrive in quick succession. (RIC-674)
72 2020 October 30; Version 4.3.1
73 Changes to address code analyser scans and two bug fixes identified
74 while addressing the analysis data. (RIC-673)
76 2020 October 2; Version 4.3.0
77 Add message types for traffic steering anomaly messages
79 2020 September 15; Version 4.2.4
80 Add man page for the rmr_set_low_latency() function (RIC-631)

87 on the command line (RIC-644)
89 2020 August 4; Version 4.2.1
90 Add additional environment variable dump if RMR_LOG_VLEVEL set to
93 2020 August 3; Version 4.2.0
94 Add support for the RMR_RTREQ_FREQ environment variable to control
95 the request frequency for a new route table (default 5s if not
98 2020 July 21; Version 4.1.4
99 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
101 2020 July 9; version 4.1.3
102 Allow RTS messages to be sent before the arrival of the initial
103 route table. Calls to RTS (heart beat responses) prior to the
104 initial route table load could cause a crash if a framework
105 blindly assumes that RTS is valid. (RIC-589)
107 2020 June 22; version 4.1.2
108 Fix typo in RIC Message header file.
110 Add document for message type constants and the scripts
113 2020 June 22; version 4.1.1

119 RAN_E2_RESET_RESP (12009)
121 2020 June 18; version 4.1.0
122 Bump version minor to move away from 4.0.* which will bump for any
123 patches applied back to bronze.
125 Add magic C++ goo to symtab header file allowing C++ xAPPs to use
126 the symbol table directly.
128 2020 May 06; version 4.0.5

141 2020 April 22; version 4.0.1
142 Correct message type constant for Traffic Steering predication (RIC-342)
144 2020 April 21; version 4.0.0
145 The NNG based libraries are no longer included in the RMR packages.
146 This is considered a breaking change as NNG will not be supported by
147 default. It is still possible to build with RMR-NNG libraries, but
148 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
149 Upgrading to 4.0.0 only means that the underlying transport mechanism
150 is limited only to SI95.
152 The rmr_rcv_specific() function has been deprecated as it was necessary
153 only for NNG and Nanomsg support. Its use should be discontinued.
155 2020 April 20; version 3.8.2
156 Fix bug which was preventing an instance receiving dynamic route
157 table updates. (RIC-336)
159 2020 April 20; version 3.8.1
160 Add user guide which replaces the concatenation of man pages (RIC-328)
162 2020 April 17; version 3.8.0
163 Add safe connect to avoid potential connect bug on Linux (RIC-332)
165 Change debugging in route table collector to avoid possible
166 segment fault when in level 2 debug (RIC-335)
168 2020 April 15; version 3.7.4
169 Add missing message type to header file (RIC-334)

174 2020 April 10; version 3.7.2
175 Fix bug related to static route table only mode (RIC-331)
177 2020 April 9; version 3.7.1
178 The max length restriction for receiving messages when using SI95 has
179 been removed. The length supplied during initialisation is used as
180 the "normal maximum" and default buffer allocation size, but messages
181 arriving which are larger are accepted. (RIC-309)
183 2020 April 7; version 3.7.0
184 The health check support programme was renamed to rmr_probe (RIC-308).
186 2020 April 6; version 3.6.6

213 ack/nack of meid tables (RIC-273)
215 2020 March 10; version 3.5.1
216 Add missing health check message types.
218 2020 March 9; version 3.5.0

243 Fix receive thread related core dump (ring early unlock).
245 2020 February 19; version 3.2.1
246 Added missing message types (E2-Setup)
248 2020 February 18; version 3.2.0
249 Added support for new Route Manager and it's ability to accept
250 a request for table update.
252 2020 February 14; version 3.1.3
253 Fix bug in SIsend which was causing a core dump in some cases
254 where the application attempted to send on a connection that
255 had disconnected. (RIC-207).

282 Enable support for dynamic route table updates via RMR session.
284 2020 January 16; version 3.0.0
285 Introduce support for SI95 transport library to replace NNG.
286 (RMR library versions will use leading odd numbers to avoid tag collisions
287 with the wrapper tags which will use even numbers.)
289 2019 December 9; version 1.13.1
290 Correct documentation and missing rel-notes update for RTD.
292 2019 December 6; version 1.13.0

298 was not always copied.
300 2019 November 13; version 1.12.1
301 New message type constants added to support A1.
303 2019 November 4; version 1.11.0
304 Version bump to move away from the 1.10.* to distinguish between
305 release A and the trial.
307 2019 November 7; version 1.12.0
308 Version cut to support continued development for next release
309 preserving the 1.11.* versions for release 1 (Amber) and
312 2019 October 31; version 1.10.2
313 Provide the means to increase the payload size of a received message
314 without losing the data needed to use the rmr_rts_msg() funciton.
316 2019 October 21; version 1.10.1
317 Fix to prevent null message buffer from being returned by the timeout
318 receive function if the function is passed one to reuse.
320 2019 October 21; version 1.10.1
321 Add periodic dump of send count info to stderr.
323 2019 September 27; version 1.9.0
324 Python bindings added receive all queued function and corrected a unit test
326 2019 September 25; version 1.8.3
327 Correct application level test issue causing timing problems during
328 jenkins verification testing at command and merge
330 Handle the NNG connection shutdown status which may now be
331 generated when a connection throug a proxy is reset.
333 2019 September 25; version 1.8.2
334 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
336 2019 September 19; version 1.8.1
337 Correct missing constant for wrappers.
339 2019 September 19; version 1.8.0
340 New message types added:
341 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
343 2019 September 17; version 1.7.0
344 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
345 in the environment before rmr_init() is invoked to revert to
346 synchronous first TCP connections. (Recovery connection attempts
347 have always been asynchronous).
349 2019 September 3; version 1.6.0
350 Fix bug in the rmr_rts_msg() function. If a return to sender message
351 failed, the source IP address was not correctly adjusted and could
352 cause the message to be "reflected" back to the sender on a retry.
354 Added the ability to set the source "ID" via an environment var
355 (RMR_SRC_ID). When present in the environment, the string will
356 be placed in to the message header as the source and thus be used
357 by an application calling rmr_rts_smg() to return a response to
358 the sender. If this environment variable is not present, the host
359 name (original behaviour) is used.
361 2019 August 26; version 1.4.0
362 New message types were added.
364 2019 August 16; version 1.3.0
365 New mesage types added.
367 2019 August 13; version 1.2.0 (API change, non-breaking)
368 The function rmr_get_xact() was added to proide a convenient
369 way to extract the transaction field from a message.
371 2019 August 8; version 1.1.0 (API change)
372 This change should be backward compatable/non-breaking
373 A new field has been added to the message buffer (rmr_mbuf_t).
374 This field (tp_state) is used to communicate the errno value
375 that the transport mechanism might set during send and/or
376 receive operations. C programmes should continue to use
377 errno directly, but in some environments wrappers may not be
378 able to access errno and this provides the value to them.
379 See the rmr_alloc_msg manual page for more details.
381 2019 August 6; version 1.0.45 (build changes)
382 Support for the Nanomsg transport library has been dropped.
383 The library librmr.* will no longer be included in packages.
385 Packages will install RMR libraries into the system preferred
386 target directory. On some systems this is /usr/local/lib
387 and on others it is /usr/local/lib64. The diretory is
388 determined by the sytem on which the package is built and
389 NOT by the system installing the package, so it's possible
390 that the RMR libraries end up in a strange location if the
391 .deb or .rpm file was generated on a Linux flavour that
392 has a different preference than the one where the package
395 2019 August 6; version 1.0.44 (API change)
396 Added a new message type constant.
398 2019 July 15; Version 1.0.39 (bug fix)
399 Prevent unnecessary usleep in retry loop.
401 2019 July 12; Version 1.0.38 (API change)
402 Added new message types to RIC_message_types.h.
404 2019 July 11; Version 1.0.37
406 librmr and librmr_nng
407 - Add message buffer API function rmr_trace_ref()
408 (see rmr_trace_ref.3 manual page in dev package).
