 - gotthard 25 um image reconstructed in gui and virtual hdf5 (firmware updated for slave to reverse channels)
 - master binary file in json format now
 - fixed bug introduced in 6.0.0: hdf5 files created 1 file per frame after the initial file which had maxframesperfile
+- updatedetectorserver - removes old server current binary pointing to for blackfin
+- removing copydetectorserver using tftp 
 - registerCallBackRawDataReady and registerCallBackRawDataModifyReady now gives a sls_receiver_header* instead of a char*, and uint32_t to size_t
 - registerCallBackStartAcquisition gave incorrect imagesize (+120 bytes). corrected.
 - registerCallBackStartAcquisition parameter is a const string reference
