RMR Release Notes 
============================================================================================ 
 
The following is a list of release highlights for the core 
RMR library and wrappers which are housed in the same 
repository. These are extracted directly from the 
CHANGES_*.txt files at the repo root; please refer to those 
files for a completely up to date listing of API changes (as 
generated documents may lag). 
 
The RMR repo houses two distinct release entities: the core 
RMR package and the python wrapper package. To avoid naming 
conflicts (tags mostly) The core package uses odd major 
version numbers (e.g. 3.2.1) and the wrapper package uses 
even major version numbers. The release notes are split into 
two sections; please be sure to scroll to the section that is 
appropriate.

RMR_ASYNC_CONN=0 in the environment before rmr_init() is

(Recovery connection attempts have always been asynchronous). 
 
 
2019 September 3; version 1.6.0 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
Fix bug in the rmr_rts_msg() function. If a return to sender 
message failed, the source IP address was not correctly 
adjusted and could cause the message to be "reflected" back 
to the sender on a retry. 
 
Added the ability to set the source "ID" via an environment 
var (RMR_SRC_ID). When present in the environment, the string 
will be placed in to the message header as the source and 
thus be used by an application calling rmr_rts_smg() to 
return a response to the sender. If this environment variable 
is not present, the host name (original behaviour) is used. 
 
 
2019 August 26; version 1.4.0 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
New message types were added. 
 
 
2019 August 16; version 1.3.0 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
New mesage types added. 
 
 
2019 August 13; version 1.2.0 (API change, non-breaking) 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
The function rmr_get_xact() was added to proide a convenient 
way to extract the transaction field from a message. 
 
 
2019 August 8; version 1.1.0 (API change) 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
This change should be backward compatable/non-breaking A new 
field has been added to the message buffer (rmr_mbuf_t). This 
field (tp_state) is used to communicate the errno value that 
the transport mechanism might set during send and/or receive 
operations. C programmes should continue to use errno 
directly, but in some environments wrappers may not be able 
to access errno and this provides the value to them. See the 
rmr_alloc_msg manual page for more details. 
 
 
2019 August 6; version 1.0.45 (build changes) 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
Support for the Nanomsg transport library has been dropped. 
The library librmr.* will no longer be included in packages. 
 
Packages will install RMR libraries into the system preferred 
target directory. On some systems this is /usr/local/lib and 
on others it is /usr/local/lib64. The diretory is determined 
by the sytem on which the package is built and NOT by the 
system installing the package, so it's possible that the RMR 
libraries end up in a strange location if the .deb or .rpm 
file was generated on a Linux flavour that has a different 
preference than the one where the package is installed. 
 
 
2019 August 6; version 1.0.44 (API change) 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
Added a new message type constant. 
 
 
2019 July 15; Version 1.0.39 (bug fix) 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
Prevent unnecessary usleep in retry loop. 
 
 
2019 July 12; Version 1.0.38 (API change) 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
Added new message types to RIC_message_types.h. 
 
 
2019 July 11; Version 1.0.37 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 
 
librmr and librmr_nng - Add message buffer API function 
rmr_trace_ref() (see rmr_trace_ref.3 manual page in dev 
package).
