8 2021 February 08; Version 4.6.0
9 Enhanced to use millisecond based timestamps when writing log messages.
12 Enhanced to eliminate the reqirement that the file specified by the
13 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
14 will correctly find this file if it is created after initialisation.
15 Further, if the environment variable is not given, the user may create
16 and populate /tmp/rmr.v at any time and the contents of this file will
17 be used as if it were supplied via the environment variable. This should
18 make debugging in existing containers easier.

87 2020 July 9; version 4.1.3
88 Allow RTS messages to be sent before the arrival of the initial
89 route table. Calls to RTS (heart beat responses) prior to the
90 initial route table load could cause a crash if a framework
91 blindly assumes that RTS is valid. (RIC-589)
93 2020 June 22; version 4.1.2
94 Fix typo in RIC Message header file.
96 Add document for message type constants and the scripts
99 2020 June 22; version 4.1.1

127 2020 April 22; version 4.0.1
128 Correct message type constant for Traffic Steering predication (RIC-342)
130 2020 April 21; version 4.0.0
131 The NNG based libraries are no longer included in the RMR packages.
132 This is considered a breaking change as NNG will not be supported by
133 default. It is still possible to build with RMR-NNG libraries, but
134 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
135 Upgrading to 4.0.0 only means that the underlying transport mechanism
136 is limited only to SI95.
138 The rmr_rcv_specific() function has been deprecated as it was necessary
139 only for NNG and Nanomsg support. Its use should be discontinued.
141 2020 April 20; version 3.8.2
142 Fix bug which was preventing an instance receiving dynamic route
143 table updates. (RIC-336)
145 2020 April 20; version 3.8.1

152 segment fault when in level 2 debug (RIC-335)
154 2020 April 15; version 3.7.4

161 Fix bug related to static route table only mode (RIC-331)
163 2020 April 9; version 3.7.1
164 The max length restriction for receiving messages when using SI95 has
165 been removed. The length supplied during initialisation is used as
166 the "normal maximum" and default buffer allocation size, but messages
167 arriving which are larger are accepted. (RIC-309)
169 2020 April 7; version 3.7.0
170 The health check support programme was renamed to rmr_probe (RIC-308).
172 2020 April 6; version 3.6.6

234 2020 February 18; version 3.2.0

236 a request for table update.
238 2020 February 14; version 3.1.3
239 Fix bug in SIsend which was causing a core dump in some cases

270 2020 January 16; version 3.0.0
271 Introduce support for SI95 transport library to replace NNG.
272 (RMR library versions will use leading odd numbers to avoid tag collisions
273 with the wrapper tags which will use even numbers.)
275 2019 December 9; version 1.13.1
276 Correct documentation and missing rel-notes update for RTD.
278 2019 December 6; version 1.13.0

284 was not always copied.
286 2019 November 13; version 1.12.1
287 New message type constants added to support A1.
289 2019 November 4; version 1.11.0
290 Version bump to move away from the 1.10.* to distinguish between

298 2019 October 31; version 1.10.2
299 Provide the means to increase the payload size of a received message

302 2019 October 21; version 1.10.1
303 Fix to prevent null message buffer from being returned by the timeout
304 receive function if the function is passed one to reuse.
306 2019 October 21; version 1.10.1
307 Add periodic dump of send count info to stderr.
309 2019 September 27; version 1.9.0
310 Python bindings added receive all queued function and corrected a unit test
312 2019 September 25; version 1.8.3
313 Correct application level test issue causing timing problems during
314 jenkins verification testing at command and merge
316 Handle the NNG connection shutdown status which may now be
317 generated when a connection throug a proxy is reset.
319 2019 September 25; version 1.8.2
320 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
322 2019 September 19; version 1.8.1
323 Correct missing constant for wrappers.
325 2019 September 19; version 1.8.0
326 New message types added:
327 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
329 2019 September 17; version 1.7.0
330 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
331 in the environment before rmr_init() is invoked to revert to
332 synchronous first TCP connections. (Recovery connection attempts
333 have always been asynchronous).
335 2019 September 3; version 1.6.0
336 Fix bug in the rmr_rts_msg() function. If a return to sender message
337 failed, the source IP address was not correctly adjusted and could
338 cause the message to be "reflected" back to the sender on a retry.
340 Added the ability to set the source "ID" via an environment var
341 (RMR_SRC_ID). When present in the environment, the string will
342 be placed in to the message header as the source and thus be used
343 by an application calling rmr_rts_smg() to return a response to
344 the sender. If this environment variable is not present, the host
345 name (original behaviour) is used.
347 2019 August 26; version 1.4.0
348 New message types were added.
350 2019 August 16; version 1.3.0
351 New mesage types added.
353 2019 August 13; version 1.2.0 (API change, non-breaking)
354 The function rmr_get_xact() was added to proide a convenient
355 way to extract the transaction field from a message.
357 2019 August 8; version 1.1.0 (API change)
358 This change should be backward compatable/non-breaking
359 A new field has been added to the message buffer (rmr_mbuf_t).
360 This field (tp_state) is used to communicate the errno value
361 that the transport mechanism might set during send and/or
362 receive operations. C programmes should continue to use
363 errno directly, but in some environments wrappers may not be
364 able to access errno and this provides the value to them.
365 See the rmr_alloc_msg manual page for more details.
367 2019 August 6; version 1.0.45 (build changes)
368 Support for the Nanomsg transport library has been dropped.
369 The library librmr.* will no longer be included in packages.
371 Packages will install RMR libraries into the system preferred
372 target directory. On some systems this is /usr/local/lib
373 and on others it is /usr/local/lib64. The diretory is
374 determined by the sytem on which the package is built and
375 NOT by the system installing the package, so it's possible
376 that the RMR libraries end up in a strange location if the
377 .deb or .rpm file was generated on a Linux flavour that
378 has a different preference than the one where the package
381 2019 August 6; version 1.0.44 (API change)
382 Added a new message type constant.
384 2019 July 15; Version 1.0.39 (bug fix)
385 Prevent unnecessary usleep in retry loop.
387 2019 July 12; Version 1.0.38 (API change)
388 Added new message types to RIC_message_types.h.
390 2019 July 11; Version 1.0.37
392 librmr and librmr_nng
393 - Add message buffer API function rmr_trace_ref()
394 (see rmr_trace_ref.3 manual page in dev package).
