8 2020 November 4; Version 4.4.1
9 Changes to correct complaints generated by a code scan. (RIC-673)
11 2020 November 4; Version 4.4.0
12 Changes to address a potential race condition when route tables
13 arrive in quick succession. (RIC-674)
15 2020 October 30; Version 4.3.1
16 Changes to address code analyser scans and two bug fixes identified
17 while addressing the analysis data. (RIC-673)

20 Add message types for traffic steering anomaly messages
22 2020 September 15; Version 4.2.4

36 2020 August 3; Version 4.2.0
37 Add support for the RMR_RTREQ_FREQ environment variable to control
38 the request frequency for a new route table (default 5s if not
41 2020 July 21; Version 4.1.4
42 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
44 2020 July 9; version 4.1.3
45 Allow RTS messages to be sent before the arrival of the initial
46 route table. Calls to RTS (heart beat responses) prior to the
47 initial route table load could cause a crash if a framework
48 blindly assumes that RTS is valid. (RIC-589)
50 2020 June 22; version 4.1.2
51 Fix typo in RIC Message header file.
53 Add document for message type constants and the scripts
56 2020 June 22; version 4.1.1
57 Add new message types to RIC header file for
61 RAN_E2_RESET_REQ (12008)
62 RAN_E2_RESET_RESP (12009)
64 2020 June 18; version 4.1.0
65 Bump version minor to move away from 4.0.* which will bump for any
66 patches applied back to bronze.

69 the symbol table directly.
71 2020 May 06; version 4.0.5
72 Fix the bug in SI95 receive message management semaphore count
75 2020 April 29; version 4.0.4
76 Fix the traffic steering message type constants (again) (RIC-342)
78 2020 April 28; version 4.0.3
79 Fix sonar flagged bugs (RIC-78)
81 2020 April 24; version 4.0.2
82 Correct bug in SI95 transport header length validation (RIC-341)
84 2020 April 22; version 4.0.1
85 Correct message type constant for Traffic Steering predication (RIC-342)
87 2020 April 21; version 4.0.0
88 The NNG based libraries are no longer included in the RMR packages.
89 This is considered a breaking change as NNG will not be supported by
90 default. It is still possible to build with RMR-NNG libraries, but
91 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
92 Upgrading to 4.0.0 only means that the underlying transport mechanism
93 is limited only to SI95.
95 The rmr_rcv_specific() function has been deprecated as it was necessary
96 only for NNG and Nanomsg support. Its use should be discontinued.
98 2020 April 20; version 3.8.2
99 Fix bug which was preventing an instance receiving dynamic route
100 table updates. (RIC-336)
102 2020 April 20; version 3.8.1
103 Add user guide which replaces the concatenation of man pages (RIC-328)
105 2020 April 17; version 3.8.0
106 Add safe connect to avoid potential connect bug on Linux (RIC-332)
108 Change debugging in route table collector to avoid possible
109 segment fault when in level 2 debug (RIC-335)
111 2020 April 15; version 3.7.4
112 Add missing message type to header file (RIC-334)

117 2020 April 10; version 3.7.2
118 Fix bug related to static route table only mode (RIC-331)
120 2020 April 9; version 3.7.1
121 The max length restriction for receiving messages when using SI95 has
122 been removed. The length supplied during initialisation is used as
123 the "normal maximum" and default buffer allocation size, but messages
124 arriving which are larger are accepted. (RIC-309)
126 2020 April 7; version 3.7.0
127 The health check support programme was renamed to rmr_probe (RIC-308).
129 2020 April 6; version 3.6.6

131 Correct bug in SI initialisation module
133 2020 April 2; version 3.6.5

156 ack/nack of meid tables (RIC-273)
158 2020 March 10; version 3.5.1
159 Add missing health check message types.
161 2020 March 9; version 3.5.0
162 Added new wormhole send function: rmr_wh_call().
164 2020 March 6; version 3.4.0

188 2020 February 19; version 3.2.1
189 Added missing message types (E2-Setup)
191 2020 February 18; version 3.2.0

193 a request for table update.
195 2020 February 14; version 3.1.3
196 Fix bug in SIsend which was causing a core dump in some cases
197 where the application attempted to send on a connection that
198 had disconnected. (RIC-207).

227 2020 January 16; version 3.0.0
228 Introduce support for SI95 transport library to replace NNG.
229 (RMR library versions will use leading odd numbers to avoid tag collisions
230 with the wrapper tags which will use even numbers.)
232 2019 December 9; version 1.13.1
233 Correct documentation and missing rel-notes update for RTD.
235 2019 December 6; version 1.13.0

243 2019 November 13; version 1.12.1
244 New message type constants added to support A1.
246 2019 November 4; version 1.11.0
247 Version bump to move away from the 1.10.* to distinguish between

255 2019 October 31; version 1.10.2
256 Provide the means to increase the payload size of a received message
257 without losing the data needed to use the rmr_rts_msg() funciton.
259 2019 October 21; version 1.10.1
260 Fix to prevent null message buffer from being returned by the timeout
261 receive function if the function is passed one to reuse.
263 2019 October 21; version 1.10.1
264 Add periodic dump of send count info to stderr.
266 2019 September 27; version 1.9.0
267 Python bindings added receive all queued function and corrected a unit test
269 2019 September 25; version 1.8.3
270 Correct application level test issue causing timing problems during
271 jenkins verification testing at command and merge
273 Handle the NNG connection shutdown status which may now be
274 generated when a connection throug a proxy is reset.
276 2019 September 25; version 1.8.2
277 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
279 2019 September 19; version 1.8.1
280 Correct missing constant for wrappers.
282 2019 September 19; version 1.8.0
283 New message types added:
284 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
286 2019 September 17; version 1.7.0
287 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
288 in the environment before rmr_init() is invoked to revert to
289 synchronous first TCP connections. (Recovery connection attempts
290 have always been asynchronous).
292 2019 September 3; version 1.6.0
293 Fix bug in the rmr_rts_msg() function. If a return to sender message
294 failed, the source IP address was not correctly adjusted and could
295 cause the message to be "reflected" back to the sender on a retry.
297 Added the ability to set the source "ID" via an environment var
298 (RMR_SRC_ID). When present in the environment, the string will
299 be placed in to the message header as the source and thus be used
300 by an application calling rmr_rts_smg() to return a response to
301 the sender. If this environment variable is not present, the host
302 name (original behaviour) is used.
304 2019 August 26; version 1.4.0
305 New message types were added.
307 2019 August 16; version 1.3.0
308 New mesage types added.
310 2019 August 13; version 1.2.0 (API change, non-breaking)
311 The function rmr_get_xact() was added to proide a convenient
312 way to extract the transaction field from a message.
314 2019 August 8; version 1.1.0 (API change)
315 This change should be backward compatable/non-breaking
316 A new field has been added to the message buffer (rmr_mbuf_t).
317 This field (tp_state) is used to communicate the errno value
318 that the transport mechanism might set during send and/or
319 receive operations. C programmes should continue to use
320 errno directly, but in some environments wrappers may not be
321 able to access errno and this provides the value to them.
322 See the rmr_alloc_msg manual page for more details.
324 2019 August 6; version 1.0.45 (build changes)
325 Support for the Nanomsg transport library has been dropped.
326 The library librmr.* will no longer be included in packages.
328 Packages will install RMR libraries into the system preferred
329 target directory. On some systems this is /usr/local/lib
330 and on others it is /usr/local/lib64. The diretory is
331 determined by the sytem on which the package is built and
332 NOT by the system installing the package, so it's possible
333 that the RMR libraries end up in a strange location if the
334 .deb or .rpm file was generated on a Linux flavour that
335 has a different preference than the one where the package
338 2019 August 6; version 1.0.44 (API change)
339 Added a new message type constant.
341 2019 July 15; Version 1.0.39 (bug fix)
342 Prevent unnecessary usleep in retry loop.
344 2019 July 12; Version 1.0.38 (API change)
345 Added new message types to RIC_message_types.h.
347 2019 July 11; Version 1.0.37
349 librmr and librmr_nng
350 - Add message buffer API function rmr_trace_ref()
351 (see rmr_trace_ref.3 manual page in dev package).
