8 2020 April 21; version 4.0.0
9 The NNG based libraries are no longer included in the RMR packages.
10 This is considered a breaking change as NNG will not be supported by
11 default. It is still possible to build with RMR-NNG libraries, but
12 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
13 Upgrading to 4.0.0 only means that the underlying transport mechanism
14 is limited only to SI95.
16 The rmr_rcv_specific() function has been deprecated as it was necessary
17 only for NNG and Nanomsg support. Its use should be discontinued.

21 table updates. (RIC-336)

42 The max length restriction for receiving messages when using SI95 has

45 arriving which are larger are accepted. (RIC-309)
47 2020 April 7; version 3.7.0
48 The health check support programme was renamed to rmr_probe (RIC-308).

149 Introduce support for SI95 transport library to replace NNG.
150 (RMR library versions will use leading odd numbers to avoid tag collisions
151 with the wrapper tags which will use even numbers.)
153 2019 December 9; version 1.13.1
154 Correct documentation and missing rel-notes update for RTD.
156 2019 December 6; version 1.13.0

177 Provide the means to increase the payload size of a received message
178 without losing the data needed to use the rmr_rts_msg() funciton.
180 2019 October 21; version 1.10.1
181 Fix to prevent null message buffer from being returned by the timeout
182 receive function if the function is passed one to reuse.
184 2019 October 21; version 1.10.1
185 Add periodic dump of send count info to stderr.
187 2019 September 27; version 1.9.0
188 Python bindings added receive all queued function and corrected a unit test
190 2019 September 25; version 1.8.3
191 Correct application level test issue causing timing problems during
192 jenkins verification testing at command and merge
194 Handle the NNG connection shutdown status which may now be
195 generated when a connection throug a proxy is reset.
197 2019 September 25; version 1.8.2
198 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
200 2019 September 19; version 1.8.1
201 Correct missing constant for wrappers.
203 2019 September 19; version 1.8.0
204 New message types added:
205 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
207 2019 September 17; version 1.7.0
208 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
209 in the environment before rmr_init() is invoked to revert to
210 synchronous first TCP connections. (Recovery connection attempts
211 have always been asynchronous).
213 2019 September 3; version 1.6.0
214 Fix bug in the rmr_rts_msg() function. If a return to sender message
215 failed, the source IP address was not correctly adjusted and could
216 cause the message to be "reflected" back to the sender on a retry.
218 Added the ability to set the source "ID" via an environment var
219 (RMR_SRC_ID). When present in the environment, the string will
220 be placed in to the message header as the source and thus be used
221 by an application calling rmr_rts_smg() to return a response to
222 the sender. If this environment variable is not present, the host
223 name (original behaviour) is used.
225 2019 August 26; version 1.4.0
226 New message types were added.
228 2019 August 16; version 1.3.0
229 New mesage types added.
231 2019 August 13; version 1.2.0 (API change, non-breaking)
232 The function rmr_get_xact() was added to proide a convenient
233 way to extract the transaction field from a message.
235 2019 August 8; version 1.1.0 (API change)
236 This change should be backward compatable/non-breaking
237 A new field has been added to the message buffer (rmr_mbuf_t).
238 This field (tp_state) is used to communicate the errno value
239 that the transport mechanism might set during send and/or
240 receive operations. C programmes should continue to use
241 errno directly, but in some environments wrappers may not be
242 able to access errno and this provides the value to them.
243 See the rmr_alloc_msg manual page for more details.
245 2019 August 6; version 1.0.45 (build changes)
246 Support for the Nanomsg transport library has been dropped.
247 The library librmr.* will no longer be included in packages.
249 Packages will install RMR libraries into the system preferred
250 target directory. On some systems this is /usr/local/lib
251 and on others it is /usr/local/lib64. The diretory is
252 determined by the sytem on which the package is built and
253 NOT by the system installing the package, so it's possible
254 that the RMR libraries end up in a strange location if the
255 .deb or .rpm file was generated on a Linux flavour that
256 has a different preference than the one where the package
259 2019 August 6; version 1.0.44 (API change)
260 Added a new message type constant.
262 2019 July 15; Version 1.0.39 (bug fix)
263 Prevent unnecessary usleep in retry loop.
265 2019 July 12; Version 1.0.38 (API change)
266 Added new message types to RIC_message_types.h.
268 2019 July 11; Version 1.0.37
270 librmr and librmr_nng
271 - Add message buffer API function rmr_trace_ref()
272 (see rmr_trace_ref.3 manual page in dev package).
