8 2020 August 4; Version 4.2.1
9 Add additional environment variable dump if RMR_LOG_VLEVEL set to
12 2020 August 3; Version 4.2.0
13 Add support for the RMR_RTREQ_FREQ environment variable to control
14 the request frequency for a new route table (default 5s if not
17 2020 July 21; Version 4.1.4
18 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
20 2020 July 9; version 4.1.3
21 Allow RTS messages to be sent before the arrival of the initial
22 route table. Calls to RTS (heart beat responses) prior to the
23 initial route table load could cause a crash if a framework
24 blindly assumes that RTS is valid. (RIC-589)
26 2020 June 22; version 4.1.2
27 Fix typo in RIC Message header file.
29 Add document for message type constants and the scripts
32 2020 June 22; version 4.1.1
33 Add new message types to RIC header file for
37 RAN_E2_RESET_REQ (12008)
38 RAN_E2_RESET_RESP (12009)
40 2020 June 18; version 4.1.0
41 Bump version minor to move away from 4.0.* which will bump for any
42 patches applied back to bronze.
44 Add magic C++ goo to symtab header file allowing C++ xAPPs to use
45 the symbol table directly.
47 2020 May 06; version 4.0.5
48 Fix the bug in SI95 receive message management semaphore count
51 2020 April 29; version 4.0.4
52 Fix the traffic steering message type constants (again) (RIC-342)
54 2020 April 28; version 4.0.3
55 Fix sonar flagged bugs (RIC-78)
57 2020 April 24; version 4.0.2
58 Correct bug in SI95 transport header length validation (RIC-341)
60 2020 April 22; version 4.0.1
61 Correct message type constant for Traffic Steering predication (RIC-342)
63 2020 April 21; version 4.0.0
64 The NNG based libraries are no longer included in the RMR packages.
65 This is considered a breaking change as NNG will not be supported by
66 default. It is still possible to build with RMR-NNG libraries, but
67 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
68 Upgrading to 4.0.0 only means that the underlying transport mechanism
69 is limited only to SI95.
71 The rmr_rcv_specific() function has been deprecated as it was necessary
72 only for NNG and Nanomsg support. Its use should be discontinued.
74 2020 April 20; version 3.8.2
75 Fix bug which was preventing an instance receiving dynamic route
76 table updates. (RIC-336)
78 2020 April 20; version 3.8.1
79 Add user guide which replaces the concatenation of man pages (RIC-328)
81 2020 April 17; version 3.8.0
82 Add safe connect to avoid potential connect bug on Linux (RIC-332)
84 Change debugging in route table collector to avoid possible
85 segment fault when in level 2 debug (RIC-335)
87 2020 April 15; version 3.7.4
88 Add missing message type to header file (RIC-334)
90 2020 April 14; version 3.7.3
91 Fix bug in rmr_call() when using SI95 (RIC-333)
93 2020 April 10; version 3.7.2
94 Fix bug related to static route table only mode (RIC-331)
96 2020 April 9; version 3.7.1
97 The max length restriction for receiving messages when using SI95 has
98 been removed. The length supplied during initialisation is used as
99 the "normal maximum" and default buffer allocation size, but messages
100 arriving which are larger are accepted. (RIC-309)
102 2020 April 7; version 3.7.0
103 The health check support programme was renamed to rmr_probe (RIC-308).

132 ack/nack of meid tables (RIC-273)
134 2020 March 10; version 3.5.1
135 Add missing health check message types.
137 2020 March 9; version 3.5.0
138 Added new wormhole send function: rmr_wh_call().
140 2020 March 6; version 3.4.0

162 Fix receive thread related core dump (ring early unlock).
164 2020 February 19; version 3.2.1
165 Added missing message types (E2-Setup)
167 2020 February 18; version 3.2.0

169 a request for table update.
171 2020 February 14; version 3.1.3
172 Fix bug in SIsend which was causing a core dump in some cases

201 Enable support for dynamic route table updates via RMR session.
203 2020 January 16; version 3.0.0
204 Introduce support for SI95 transport library to replace NNG.
205 (RMR library versions will use leading odd numbers to avoid tag collisions
206 with the wrapper tags which will use even numbers.)
208 2019 December 9; version 1.13.1
209 Correct documentation and missing rel-notes update for RTD.
211 2019 December 6; version 1.13.0

217 was not always copied.
219 2019 November 13; version 1.12.1
220 New message type constants added to support A1.
222 2019 November 4; version 1.11.0
223 Version bump to move away from the 1.10.* to distinguish between

228 preserving the 1.11.* versions for release 1 (Amber) and
231 2019 October 31; version 1.10.2
232 Provide the means to increase the payload size of a received message
233 without losing the data needed to use the rmr_rts_msg() funciton.
235 2019 October 21; version 1.10.1
236 Fix to prevent null message buffer from being returned by the timeout
237 receive function if the function is passed one to reuse.
239 2019 October 21; version 1.10.1
240 Add periodic dump of send count info to stderr.
242 2019 September 27; version 1.9.0
243 Python bindings added receive all queued function and corrected a unit test
245 2019 September 25; version 1.8.3
246 Correct application level test issue causing timing problems during
247 jenkins verification testing at command and merge
249 Handle the NNG connection shutdown status which may now be
250 generated when a connection throug a proxy is reset.
252 2019 September 25; version 1.8.2
253 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
255 2019 September 19; version 1.8.1
256 Correct missing constant for wrappers.
258 2019 September 19; version 1.8.0
259 New message types added:
260 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
262 2019 September 17; version 1.7.0
263 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
264 in the environment before rmr_init() is invoked to revert to
265 synchronous first TCP connections. (Recovery connection attempts
266 have always been asynchronous).
268 2019 September 3; version 1.6.0
269 Fix bug in the rmr_rts_msg() function. If a return to sender message
270 failed, the source IP address was not correctly adjusted and could
271 cause the message to be "reflected" back to the sender on a retry.
273 Added the ability to set the source "ID" via an environment var
274 (RMR_SRC_ID). When present in the environment, the string will
275 be placed in to the message header as the source and thus be used
276 by an application calling rmr_rts_smg() to return a response to
277 the sender. If this environment variable is not present, the host
278 name (original behaviour) is used.
280 2019 August 26; version 1.4.0
281 New message types were added.
283 2019 August 16; version 1.3.0
284 New mesage types added.
286 2019 August 13; version 1.2.0 (API change, non-breaking)
287 The function rmr_get_xact() was added to proide a convenient
288 way to extract the transaction field from a message.
290 2019 August 8; version 1.1.0 (API change)
291 This change should be backward compatable/non-breaking
292 A new field has been added to the message buffer (rmr_mbuf_t).
293 This field (tp_state) is used to communicate the errno value
294 that the transport mechanism might set during send and/or
295 receive operations. C programmes should continue to use
296 errno directly, but in some environments wrappers may not be
297 able to access errno and this provides the value to them.
298 See the rmr_alloc_msg manual page for more details.
300 2019 August 6; version 1.0.45 (build changes)
301 Support for the Nanomsg transport library has been dropped.
302 The library librmr.* will no longer be included in packages.
304 Packages will install RMR libraries into the system preferred
305 target directory. On some systems this is /usr/local/lib
306 and on others it is /usr/local/lib64. The diretory is
307 determined by the sytem on which the package is built and
308 NOT by the system installing the package, so it's possible
309 that the RMR libraries end up in a strange location if the
310 .deb or .rpm file was generated on a Linux flavour that
311 has a different preference than the one where the package
314 2019 August 6; version 1.0.44 (API change)
315 Added a new message type constant.
317 2019 July 15; Version 1.0.39 (bug fix)
318 Prevent unnecessary usleep in retry loop.
320 2019 July 12; Version 1.0.38 (API change)
321 Added new message types to RIC_message_types.h.
323 2019 July 11; Version 1.0.37
325 librmr and librmr_nng
326 - Add message buffer API function rmr_trace_ref()
327 (see rmr_trace_ref.3 manual page in dev package).
