This list assumes DiFX 2.0.2 is to be released relative soon (a few months) after DiFX 2.0.1

• Bug: when nfftchan is more than xmacstridelength in pulsar mode, only the first xmacstridelength channels appear properly populated
• Bug: FATAL Mk5DataStream::calculateControlParams: bufferindex>=bufferbytes: bufferindex=170311680 >= bufferbytes=170311680 atsegment = 7

• vex2difx (or other) support for creating .machines and .threads (from the eVLBI perspective)
• Chase up and eliminate the cause of occasional òÀÜSomehow Visibility X ended up with Y+1 subintegrations - was expecting only YòÀÝ errors

These are probably beyond the horizon of DiFX 2.0.2 unless a champion comes in to make them reality

• vex2 support (relies on vex2 finalization and some support from field systems)
• Generalized GUI with unified database backend (Work progressing at MPIfR and USNO)
• Amplitude correction for primary beam effects for off-center correlation (To be addressed at 2011 meeting at Haystack)
• Move to a binary format for pcal files and name by datastream not by antenna name (To be addressed at 2011 meeting at Haystack)

• LBA format data now scaled roughly correctly (removing the need for large ACCOR corrections)
• There was a bug when xmaclength was > nfftchan for pulsar processing - this has been corrected
• guardns was incorrectly (overzealously) calculated in mpifxcorr
• òÀÜMk5DataStream::calculateControlParams: bufferindex>=bufferbytesòÀÝ bug fixed
• Low weight reads could result in uninitialized memory
• Streamstor XLRRead() bug work-around installed several places (read at position 0 before reading at position > 0)
• Fix to pulse calibration data ordering for LSB or reordered channels
• Pulse Cal amplitude now divided by pulse cal averaging time in seconds

• Mark5-based correlation: easy access to SMART data (can be viewed with getsmart)
• Mark5-based correlation: emit multicast message containing drive statistics after each scan
• VSIS interface added to mk5daemon
• Experimental support for non power-of-2 FFT lengths
• New utilities: mk5map, fileto5c, record5c
• New features added to existing utilities:
  • mk5cp: copy without reference to a directory, send data over ssh
  • vsn: get SMART data
