8 2020 August 3; Version 4.2.0
9 Add support for the RMR_RTREQ_FREQ environment variable to control
10 the request frequency for a new route table (default 5s if not
13 2020 July 21; Version 4.1.4
14 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
16 2020 July 9; version 4.1.3
17 Allow RTS messages to be sent before the arrival of the initial
18 route table. Calls to RTS (heart beat responses) prior to the
19 initial route table load could cause a crash if a framework
20 blindly assumes that RTS is valid. (RIC-589)
22 2020 June 22; version 4.1.2
23 Fix typo in RIC Message header file.
25 Add document for message type constants and the scripts
28 2020 June 22; version 4.1.1
29 Add new message types to RIC header file for
33 RAN_E2_RESET_REQ (12008)
34 RAN_E2_RESET_RESP (12009)
36 2020 June 18; version 4.1.0
37 Bump version minor to move away from 4.0.* which will bump for any
38 patches applied back to bronze.
40 Add magic C++ goo to symtab header file allowing C++ xAPPs to use
41 the symbol table directly.
43 2020 May 06; version 4.0.5
44 Fix the bug in SI95 receive message management semaphore count
47 2020 April 29; version 4.0.4
48 Fix the traffic steering message type constants (again) (RIC-342)
50 2020 April 28; version 4.0.3
51 Fix sonar flagged bugs (RIC-78)
53 2020 April 24; version 4.0.2
54 Correct bug in SI95 transport header length validation (RIC-341)
56 2020 April 22; version 4.0.1
57 Correct message type constant for Traffic Steering predication (RIC-342)
59 2020 April 21; version 4.0.0
60 The NNG based libraries are no longer included in the RMR packages.
61 This is considered a breaking change as NNG will not be supported by
62 default. It is still possible to build with RMR-NNG libraries, but
63 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
64 Upgrading to 4.0.0 only means that the underlying transport mechanism
65 is limited only to SI95.
67 The rmr_rcv_specific() function has been deprecated as it was necessary
68 only for NNG and Nanomsg support. Its use should be discontinued.
70 2020 April 20; version 3.8.2
71 Fix bug which was preventing an instance receiving dynamic route
72 table updates. (RIC-336)
74 2020 April 20; version 3.8.1
75 Add user guide which replaces the concatenation of man pages (RIC-328)
77 2020 April 17; version 3.8.0
78 Add safe connect to avoid potential connect bug on Linux (RIC-332)
80 Change debugging in route table collector to avoid possible
81 segment fault when in level 2 debug (RIC-335)
83 2020 April 15; version 3.7.4
84 Add missing message type to header file (RIC-334)
86 2020 April 14; version 3.7.3
87 Fix bug in rmr_call() when using SI95 (RIC-333)
89 2020 April 10; version 3.7.2
90 Fix bug related to static route table only mode (RIC-331)
92 2020 April 9; version 3.7.1
93 The max length restriction for receiving messages when using SI95 has
94 been removed. The length supplied during initialisation is used as
95 the "normal maximum" and default buffer allocation size, but messages
96 arriving which are larger are accepted. (RIC-309)
98 2020 April 7; version 3.7.0
99 The health check support programme was renamed to rmr_probe (RIC-308).

128 ack/nack of meid tables (RIC-273)

131 Add missing health check message types.
133 2020 March 9; version 3.5.0
134 Added new wormhole send function: rmr_wh_call().
136 2020 March 6; version 3.4.0

158 Fix receive thread related core dump (ring early unlock).
160 2020 February 19; version 3.2.1
161 Added missing message types (E2-Setup)
163 2020 February 18; version 3.2.0
164 Added support for new Route Manager and it's ability to accept
165 a request for table update.
167 2020 February 14; version 3.1.3
168 Fix bug in SIsend which was causing a core dump in some cases
169 where the application attempted to send on a connection that
170 had disconnected. (RIC-207).

199 2020 January 16; version 3.0.0
200 Introduce support for SI95 transport library to replace NNG.
201 (RMR library versions will use leading odd numbers to avoid tag collisions
202 with the wrapper tags which will use even numbers.)
204 2019 December 9; version 1.13.1
205 Correct documentation and missing rel-notes update for RTD.
207 2019 December 6; version 1.13.0

213 was not always copied.
215 2019 November 13; version 1.12.1

227 2019 October 31; version 1.10.2
228 Provide the means to increase the payload size of a received message

231 2019 October 21; version 1.10.1
232 Fix to prevent null message buffer from being returned by the timeout
233 receive function if the function is passed one to reuse.
235 2019 October 21; version 1.10.1
236 Add periodic dump of send count info to stderr.
238 2019 September 27; version 1.9.0
239 Python bindings added receive all queued function and corrected a unit test
241 2019 September 25; version 1.8.3
242 Correct application level test issue causing timing problems during

248 2019 September 25; version 1.8.2
249 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
251 2019 September 19; version 1.8.1
252 Correct missing constant for wrappers.
254 2019 September 19; version 1.8.0
255 New message types added:
256 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
258 2019 September 17; version 1.7.0
259 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
260 in the environment before rmr_init() is invoked to revert to
261 synchronous first TCP connections. (Recovery connection attempts
262 have always been asynchronous).
264 2019 September 3; version 1.6.0
265 Fix bug in the rmr_rts_msg() function. If a return to sender message
266 failed, the source IP address was not correctly adjusted and could
267 cause the message to be "reflected" back to the sender on a retry.
269 Added the ability to set the source "ID" via an environment var
270 (RMR_SRC_ID). When present in the environment, the string will
271 be placed in to the message header as the source and thus be used
272 by an application calling rmr_rts_smg() to return a response to
273 the sender. If this environment variable is not present, the host
274 name (original behaviour) is used.
276 2019 August 26; version 1.4.0
277 New message types were added.
279 2019 August 16; version 1.3.0
280 New mesage types added.
282 2019 August 13; version 1.2.0 (API change, non-breaking)
283 The function rmr_get_xact() was added to proide a convenient
284 way to extract the transaction field from a message.
286 2019 August 8; version 1.1.0 (API change)
287 This change should be backward compatable/non-breaking
288 A new field has been added to the message buffer (rmr_mbuf_t).
289 This field (tp_state) is used to communicate the errno value
290 that the transport mechanism might set during send and/or
291 receive operations. C programmes should continue to use
292 errno directly, but in some environments wrappers may not be
293 able to access errno and this provides the value to them.
294 See the rmr_alloc_msg manual page for more details.
296 2019 August 6; version 1.0.45 (build changes)
297 Support for the Nanomsg transport library has been dropped.
298 The library librmr.* will no longer be included in packages.
300 Packages will install RMR libraries into the system preferred
301 target directory. On some systems this is /usr/local/lib
302 and on others it is /usr/local/lib64. The diretory is
303 determined by the sytem on which the package is built and
304 NOT by the system installing the package, so it's possible
305 that the RMR libraries end up in a strange location if the
306 .deb or .rpm file was generated on a Linux flavour that
307 has a different preference than the one where the package
310 2019 August 6; version 1.0.44 (API change)
311 Added a new message type constant.
313 2019 July 15; Version 1.0.39 (bug fix)
314 Prevent unnecessary usleep in retry loop.
316 2019 July 12; Version 1.0.38 (API change)
317 Added new message types to RIC_message_types.h.
319 2019 July 11; Version 1.0.37
321 librmr and librmr_nng
322 - Add message buffer API function rmr_trace_ref()
323 (see rmr_trace_ref.3 manual page in dev package).
