Hello,

how can I add something to the release notes? I would like to mention=20
some RTEMS changes.

The RTEMS thread model implementation changed. For the mutexes=20
self-contained objects defined in Newlib <sys/lock.h> are used instead=20
of Classic API semaphores.  The keys and the once function are directly=20
defined via <pthread.h>.  Condition variables are provided via Newlib=20
<sys/lock.h>. The RTEMS thread model supports now the C++11 threads.

The OpenMP support uses now self-contained objects provided by Newlib=20
<sys/lock.h> and offers a significantly better performance compared to=20
the POSIX configuration. It is possible to configure scheduler instance=20
specific thread pools.

--=20
