<div dir="ltr">The short story (as I recall) was that a bug in DiFX regarding complex sampled data and a bug in one of the DBEs cancelled out prior to 2.5.4.

handled in the backends and DiFX. 2.5.4 was created as a stable <br>
processing release for VGOS until the resources were free to guarantee <br>
operation in a "current" release. And fixing this situation requires <br>
some coordination with the way backends are operated. I'm not fluent in <br>
the details.<br>

A 2.7.1 release for the EHT processing of the 2021 campaign is likely to <br>
occur in the next few months (as the media need to be recycled) and a <br>
2.7-based release suitable for VGOS was one of the options discussed, <br>
but I do not know the current plan for VGOS.<br>
