1) Delta and blend SSE and standard alogirthms inside 2) Changed event streaming to use sendfile() syscall if available 3) Direct memory capture (Less memcpys required) 4) Added macros for BGR24 and RGB32(and its variants) formats 5) Modified Monitors database table to add a target colorspace option 6) Changed most image buffer allocations to be on 16 byte boundary, work still in progress 7) Added Target colorspace instead of the old colours selection. this one also visible to local cameras 8) Replacing Y deltas option with ZM_CPU_EXTENSIONS 9) Added SSE detection code 10) Changed some code to make linking success with inlining enabled. 11) Some other changes and work still in progress for some listed above
