[Difx-users] DiFX 2.9.0 released, DiFX users meeting update {External}

[Adam Deller]

Hi difx-users,

Those of you subscribed to the DiFX github repo will have already seen, but
DiFX 2.9.0 was officially tagged today! I'd like to express my
heartfelt appreciation of everyone who has contributed patches,
development, and testing to this release. In particular, I'd like to thank
Shaoguang who has done a lot of work getting the 2.9.0 feature branch
merged back into main, and Walter who has done an outsized amount of
testing (in addition to his usual impressive dev load!) But again, a huge
thanks to the whole community.

You can see DiFX-2.9.0 (and a summary of the commits that went into it) on
https://github.com/difx/difx/releases/tag/v2.9.0https://github.com/difx/difx/releases/tag/v2.9.0.
More details on the (extensive!) changelog from 2.8 to 2.9 at
https://github.com/difx/difx/wiki/changelog. Highlights include updating
the trig functions in mpifxcorr (the very low precision Sin/Cos that was
brought in several generations of IPP ago really complicated testing for a
little while!) lots of advances with CODIF, experimental calibration
application in difx2fits, ability for difxcalc to handle large arrays, and
plenty of improvements for corner cases in vex2difx. DiFX-2.9 should be
suitable for pretty much everyone, but if you have any questions about
whether a particular issues has been solved, please feel free to ask.

We'll be aiming to release more frequent updates going forward, so if you
see any issues with DiFX-2.9, please let us know and we can push a patch
out.

Secondly, thanks to everyone who responded with interest in (and
constraints on attending) a DIFX users workshop later this year. The
majority of the respondees did not think it would be feasible to attend a
workshop in person in November in Shanghai, so we will regretfully shelve
that idea. An in-person meeting in Asia (Shanghai and Hong Kong have both
been floated as options) is under consideration for next year, but to fill
the gap, I'd like to gauge whether there is interest in having a shorter,
online-only DiFX workshop this year. Rather than including extensive status
summaries and developer sessions, I'd propose that we focus on current
issues/challenges/feature requests. Would people be interested in having
something like this? I'd propose maybe 2x3 hour sessions on different days
(depending on demand, and with the agenda set in advance by expression of
interest to present), with a few presentations followed by discussions. Let
me know if you'd be interested in participating in something like this.

Happy correlating!
Adam on behalf of the difx developers
