The following are announcements related to RMR during the past 30 days; newest announcements first.
2020 24 June
Version 4.1.2 pushed. This is a change only to the RIC message types header file (corrects a problem in 4.1.1, which also change only the same header file). Message type documentation is now generated from the header file and can be found on the RTD site for RMR.
2020 17 June
Bronze branch now exists. The official tag for the release is 4.0.5 and any patches which need to be applied backwards will be done as 4.0.x versions. Development moves forward with 4.1.x
2020 May 6
Version 4.05 pushed. The change addresses a potential semaphore count issue in the receive dequeue mechanism. It will only to affect programmes which use the rmr_torcv_msg() call where calls are made with a mixture of zero timeout (non-blocking) and non-zero timeouts (blocking); an application making all of one kind or the other will not be affected. The symptoms of the issue are that it becomes possible for the rmr_torcv_msg() fuction to return a "timeout" state before waiting for the timeout period to pass.
...
Version 4.0.0 was pushed. There are NOT any changes to the API; this change removes the RMR NNG libraries (librmr_nng.*) from the packages, and adds some unit tests.
2020 April 20
Version 3.8.2 pushed. This applies a CRITICAL FIX to the SI95 portion of the library. A bug introduced in the 3.7.2 patch was causing RMR to fail to request a dynamic update from the Route Manager. If any 3.7 version of RMR, or 3.8.0 version, was applied it must be replaced with 3.8.2 or later to avoid route table issues.
Version 3.8.1 pushed. This change is only to push a better user guide into the RTD site and no code changes were made. Thus, there won't be a package pushed to package cloud.
2020 April 17
Version 3.8.0 pushed. This change adds a "safe connect" to the SI95 code in order to avoid the potential of a connect attempt connecting back to the same process because of the Linux connect() even port bug. This change also fixes a potential core dump in the route table collection code when debugging is enabled.
2020 April 9
Version 3.7.1 pushed. This change removes the receive buffer maximum limit when running on top of SI95.
2020 April 7
Version 3.7.0 pushed. This change renames the healthcheck support application included in the RMR runtime package to rmr_probe. The command line is the same, and for a small amount of time the old name (health_ck) will be valid.
2020 April 3
Version 3.6.5 pushed. This corrects a potential segmentation fault when evaluating the interfaces which can be used to listen for connections.
2020 March 23
Version 3.6.2 was pushed. This fixes a bug in the initialisation process when a message is reclaimed from the buffer pool. The flag values are properly initialised. This is considered an important fix and should be picked up by all applications relying on RMR.
