8 2021 April 9; version 4.7.2
9 Ensure that route table update received from route generator is not
10 applied before a full route table is received.
12 2021 April 2; version 4.7.1
13 Correct issues found during static code analysis.
15 2021 March 31; version 4.7.0
16 The route table collector thread will capture the current "offering"
17 from the Route Manager (table generator) if the RMR_SEED_RT environment
20 2021 March 10; version 4.6.1
21 Corrected unit test "framework" to make manual testing easier, and to
22 add the ability to set the code optimisation level via the CMake
23 command line parameter OPT_LEVEL=n.
25 2021 February 22; Version 4.6.0
26 Enhanced to use millisecond based timestamps when writing log messages.
29 Enhanced to eliminate the reqirement that the file specified by the
30 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
31 will correctly find this file if it is created after initialisation.
32 Further, if the environment variable is not given, the user may create
33 and populate /tmp/rmr.v at any time and the contents of this file will
34 be used as if it were supplied via the environment variable. This should
35 make debugging in existing containers easier.
37 Enhanced to send an alarm manager when the user application is not
38 receiving messages fast enough. The original messages written to
39 the standard error are still generated. (RIC-204)
41 2021 January 21; Version 4.5.2
42 Fixes the excessive TCP session bug when sending to a slow receiver
43 and a related segment fault because of too many open file descriptors.

47 Version bump to work round a CI job bug preventing push of the 4.5.0
48 packages from staging to release in package cloud. (RIC-732)
50 2021 January 8; Version 4.5.0
51 Version bump for next release tracking.
52 Corrected a potential locking issue in message allocation. (RIC-732)
54 2020 December 4; Version 4.4.6

75 2020 November 4; Version 4.4.0
76 Changes to address a potential race condition when route tables
77 arrive in quick succession. (RIC-674)
79 2020 October 30; Version 4.3.1
80 Changes to address code analyser scans and two bug fixes identified
81 while addressing the analysis data. (RIC-673)

94 on the command line (RIC-644)
96 2020 August 4; Version 4.2.1
97 Add additional environment variable dump if RMR_LOG_VLEVEL set to
100 2020 August 3; Version 4.2.0
101 Add support for the RMR_RTREQ_FREQ environment variable to control
102 the request frequency for a new route table (default 5s if not
105 2020 July 21; Version 4.1.4
106 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
108 2020 July 9; version 4.1.3
109 Allow RTS messages to be sent before the arrival of the initial
110 route table. Calls to RTS (heart beat responses) prior to the
111 initial route table load could cause a crash if a framework
112 blindly assumes that RTS is valid. (RIC-589)
114 2020 June 22; version 4.1.2
115 Fix typo in RIC Message header file.
117 Add document for message type constants and the scripts
120 2020 June 22; version 4.1.1

148 2020 April 22; version 4.0.1
149 Correct message type constant for Traffic Steering predication (RIC-342)
151 2020 April 21; version 4.0.0
152 The NNG based libraries are no longer included in the RMR packages.
153 This is considered a breaking change as NNG will not be supported by
154 default. It is still possible to build with RMR-NNG libraries, but
155 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
156 Upgrading to 4.0.0 only means that the underlying transport mechanism
157 is limited only to SI95.
159 The rmr_rcv_specific() function has been deprecated as it was necessary
160 only for NNG and Nanomsg support. Its use should be discontinued.
162 2020 April 20; version 3.8.2
163 Fix bug which was preventing an instance receiving dynamic route
164 table updates. (RIC-336)
166 2020 April 20; version 3.8.1

182 Fix bug related to static route table only mode (RIC-331)
184 2020 April 9; version 3.7.1
185 The max length restriction for receiving messages when using SI95 has
186 been removed. The length supplied during initialisation is used as
187 the "normal maximum" and default buffer allocation size, but messages
188 arriving which are larger are accepted. (RIC-309)
190 2020 April 7; version 3.7.0
191 The health check support programme was renamed to rmr_probe (RIC-308).
193 2020 April 6; version 3.6.6

291 2020 January 16; version 3.0.0
292 Introduce support for SI95 transport library to replace NNG.
293 (RMR library versions will use leading odd numbers to avoid tag collisions
294 with the wrapper tags which will use even numbers.)
296 2019 December 9; version 1.13.1
297 Correct documentation and missing rel-notes update for RTD.
299 2019 December 6; version 1.13.0

314 2019 November 7; version 1.12.0
315 Version cut to support continued development for next release
316 preserving the 1.11.* versions for release 1 (Amber) and
319 2019 October 31; version 1.10.2
320 Provide the means to increase the payload size of a received message
321 without losing the data needed to use the rmr_rts_msg() funciton.
323 2019 October 21; version 1.10.1
324 Fix to prevent null message buffer from being returned by the timeout
325 receive function if the function is passed one to reuse.
327 2019 October 21; version 1.10.1
328 Add periodic dump of send count info to stderr.
330 2019 September 27; version 1.9.0
331 Python bindings added receive all queued function and corrected a unit test
333 2019 September 25; version 1.8.3
334 Correct application level test issue causing timing problems during
335 jenkins verification testing at command and merge
337 Handle the NNG connection shutdown status which may now be
338 generated when a connection throug a proxy is reset.
340 2019 September 25; version 1.8.2
341 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
343 2019 September 19; version 1.8.1
344 Correct missing constant for wrappers.
346 2019 September 19; version 1.8.0
347 New message types added:
348 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
350 2019 September 17; version 1.7.0
351 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
352 in the environment before rmr_init() is invoked to revert to
353 synchronous first TCP connections. (Recovery connection attempts
354 have always been asynchronous).
356 2019 September 3; version 1.6.0
357 Fix bug in the rmr_rts_msg() function. If a return to sender message
358 failed, the source IP address was not correctly adjusted and could
359 cause the message to be "reflected" back to the sender on a retry.
361 Added the ability to set the source "ID" via an environment var
362 (RMR_SRC_ID). When present in the environment, the string will
363 be placed in to the message header as the source and thus be used
364 by an application calling rmr_rts_smg() to return a response to
365 the sender. If this environment variable is not present, the host
366 name (original behaviour) is used.
368 2019 August 26; version 1.4.0
369 New message types were added.
371 2019 August 16; version 1.3.0
372 New mesage types added.
374 2019 August 13; version 1.2.0 (API change, non-breaking)
375 The function rmr_get_xact() was added to proide a convenient
376 way to extract the transaction field from a message.
378 2019 August 8; version 1.1.0 (API change)
379 This change should be backward compatable/non-breaking
380 A new field has been added to the message buffer (rmr_mbuf_t).
381 This field (tp_state) is used to communicate the errno value
382 that the transport mechanism might set during send and/or
383 receive operations. C programmes should continue to use
384 errno directly, but in some environments wrappers may not be
385 able to access errno and this provides the value to them.
386 See the rmr_alloc_msg manual page for more details.
388 2019 August 6; version 1.0.45 (build changes)
389 Support for the Nanomsg transport library has been dropped.
390 The library librmr.* will no longer be included in packages.
392 Packages will install RMR libraries into the system preferred
393 target directory. On some systems this is /usr/local/lib
394 and on others it is /usr/local/lib64. The diretory is
395 determined by the sytem on which the package is built and
396 NOT by the system installing the package, so it's possible
397 that the RMR libraries end up in a strange location if the
398 .deb or .rpm file was generated on a Linux flavour that
399 has a different preference than the one where the package
402 2019 August 6; version 1.0.44 (API change)
403 Added a new message type constant.
405 2019 July 15; Version 1.0.39 (bug fix)
406 Prevent unnecessary usleep in retry loop.
408 2019 July 12; Version 1.0.38 (API change)
409 Added new message types to RIC_message_types.h.
411 2019 July 11; Version 1.0.37
413 librmr and librmr_nng
414 - Add message buffer API function rmr_trace_ref()
415 (see rmr_trace_ref.3 manual page in dev package).
