8 2020 November 4; Version 4.4.0
9 Changes to address a potential race condition when route tables
10 arrive in quick succession. (RIC-674)
12 2020 October 30; Version 4.3.1
13 Changes to address code analyser scans and two bug fixes identified
14 while addressing the analysis data. (RIC-673)

33 2020 August 3; Version 4.2.0
34 Add support for the RMR_RTREQ_FREQ environment variable to control
35 the request frequency for a new route table (default 5s if not
38 2020 July 21; Version 4.1.4
39 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
41 2020 July 9; version 4.1.3
42 Allow RTS messages to be sent before the arrival of the initial
43 route table. Calls to RTS (heart beat responses) prior to the
44 initial route table load could cause a crash if a framework
45 blindly assumes that RTS is valid. (RIC-589)
47 2020 June 22; version 4.1.2
48 Fix typo in RIC Message header file.
50 Add document for message type constants and the scripts
53 2020 June 22; version 4.1.1

58 RAN_E2_RESET_REQ (12008)
59 RAN_E2_RESET_RESP (12009)
61 2020 June 18; version 4.1.0
62 Bump version minor to move away from 4.0.* which will bump for any
63 patches applied back to bronze.

66 the symbol table directly.
68 2020 May 06; version 4.0.5
69 Fix the bug in SI95 receive message management semaphore count
72 2020 April 29; version 4.0.4

78 2020 April 24; version 4.0.2
79 Correct bug in SI95 transport header length validation (RIC-341)
81 2020 April 22; version 4.0.1
82 Correct message type constant for Traffic Steering predication (RIC-342)
84 2020 April 21; version 4.0.0
85 The NNG based libraries are no longer included in the RMR packages.
86 This is considered a breaking change as NNG will not be supported by
87 default. It is still possible to build with RMR-NNG libraries, but
88 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
89 Upgrading to 4.0.0 only means that the underlying transport mechanism
90 is limited only to SI95.
92 The rmr_rcv_specific() function has been deprecated as it was necessary
93 only for NNG and Nanomsg support. Its use should be discontinued.
95 2020 April 20; version 3.8.2
96 Fix bug which was preventing an instance receiving dynamic route
97 table updates. (RIC-336)
99 2020 April 20; version 3.8.1
100 Add user guide which replaces the concatenation of man pages (RIC-328)
102 2020 April 17; version 3.8.0
103 Add safe connect to avoid potential connect bug on Linux (RIC-332)
105 Change debugging in route table collector to avoid possible
106 segment fault when in level 2 debug (RIC-335)
108 2020 April 15; version 3.7.4

114 2020 April 10; version 3.7.2
115 Fix bug related to static route table only mode (RIC-331)
117 2020 April 9; version 3.7.1
118 The max length restriction for receiving messages when using SI95 has
119 been removed. The length supplied during initialisation is used as
120 the "normal maximum" and default buffer allocation size, but messages
121 arriving which are larger are accepted. (RIC-309)
123 2020 April 7; version 3.7.0
124 The health check support programme was renamed to rmr_probe (RIC-308).
126 2020 April 6; version 3.6.6

224 2020 January 16; version 3.0.0
225 Introduce support for SI95 transport library to replace NNG.
226 (RMR library versions will use leading odd numbers to avoid tag collisions
227 with the wrapper tags which will use even numbers.)
229 2019 December 9; version 1.13.1
230 Correct documentation and missing rel-notes update for RTD.
232 2019 December 6; version 1.13.0

252 2019 October 31; version 1.10.2
253 Provide the means to increase the payload size of a received message
254 without losing the data needed to use the rmr_rts_msg() funciton.
256 2019 October 21; version 1.10.1
257 Fix to prevent null message buffer from being returned by the timeout
258 receive function if the function is passed one to reuse.
260 2019 October 21; version 1.10.1
261 Add periodic dump of send count info to stderr.
263 2019 September 27; version 1.9.0
264 Python bindings added receive all queued function and corrected a unit test
266 2019 September 25; version 1.8.3
267 Correct application level test issue causing timing problems during
268 jenkins verification testing at command and merge
270 Handle the NNG connection shutdown status which may now be
271 generated when a connection throug a proxy is reset.
273 2019 September 25; version 1.8.2
274 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
276 2019 September 19; version 1.8.1
277 Correct missing constant for wrappers.
279 2019 September 19; version 1.8.0
280 New message types added:
281 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
283 2019 September 17; version 1.7.0
284 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
285 in the environment before rmr_init() is invoked to revert to
286 synchronous first TCP connections. (Recovery connection attempts
287 have always been asynchronous).
289 2019 September 3; version 1.6.0
290 Fix bug in the rmr_rts_msg() function. If a return to sender message
291 failed, the source IP address was not correctly adjusted and could
292 cause the message to be "reflected" back to the sender on a retry.
294 Added the ability to set the source "ID" via an environment var
295 (RMR_SRC_ID). When present in the environment, the string will
296 be placed in to the message header as the source and thus be used
297 by an application calling rmr_rts_smg() to return a response to
298 the sender. If this environment variable is not present, the host
299 name (original behaviour) is used.
301 2019 August 26; version 1.4.0
302 New message types were added.
304 2019 August 16; version 1.3.0
305 New mesage types added.
307 2019 August 13; version 1.2.0 (API change, non-breaking)
308 The function rmr_get_xact() was added to proide a convenient
309 way to extract the transaction field from a message.
311 2019 August 8; version 1.1.0 (API change)
312 This change should be backward compatable/non-breaking
313 A new field has been added to the message buffer (rmr_mbuf_t).
314 This field (tp_state) is used to communicate the errno value
315 that the transport mechanism might set during send and/or
316 receive operations. C programmes should continue to use
317 errno directly, but in some environments wrappers may not be
318 able to access errno and this provides the value to them.
319 See the rmr_alloc_msg manual page for more details.
321 2019 August 6; version 1.0.45 (build changes)
322 Support for the Nanomsg transport library has been dropped.
323 The library librmr.* will no longer be included in packages.
325 Packages will install RMR libraries into the system preferred
326 target directory. On some systems this is /usr/local/lib
327 and on others it is /usr/local/lib64. The diretory is
328 determined by the sytem on which the package is built and
329 NOT by the system installing the package, so it's possible
330 that the RMR libraries end up in a strange location if the
331 .deb or .rpm file was generated on a Linux flavour that
332 has a different preference than the one where the package
335 2019 August 6; version 1.0.44 (API change)
336 Added a new message type constant.
338 2019 July 15; Version 1.0.39 (bug fix)
339 Prevent unnecessary usleep in retry loop.
341 2019 July 12; Version 1.0.38 (API change)
342 Added new message types to RIC_message_types.h.
344 2019 July 11; Version 1.0.37
346 librmr and librmr_nng
347 - Add message buffer API function rmr_trace_ref()
348 (see rmr_trace_ref.3 manual page in dev package).
