This is an UNSTABLE release. The release has significant modifications and bug fixes, if things go wrong, it is better to revert to 1.0.0-rc.124. * jfjoch_broker: Significant improvements in TCP image socket, as a viable alternative for ZeroMQ sockets (only a single port on broker side, dynamically change number of writers, acknowledgments for written files) * jfjoch_broker: Delta phi is calculated also for still data in Bragg prediction * jfjoch_broker: Image pusher statistics are accessible via the REST interface * jfjoch_writer: Supports TCP image socket and for these auto-forking option Reviewed-on: #36 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch> Co-committed-by: Filip Leonarski <filip.leonarski@psi.ch>
