@@ -59,8 +59,10 @@ This document describes the differences between v7.0.0 and v6.x.x
 - 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
+- m3 polarity, interpolation (enables all counters when enabled), pump probe, analog pulsing, digital pulsing
 - updatedetectorserver - removes old server current binary pointing to for blackfin
 - removing copydetectorserver using tftp 
+>>>>>>> developer
 - 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
