Hi Stuart,
The versions for Infragistics and Spread will be unchanged from 07.00.175.00 :
Infragistics: 13.1.20131.2060
Farpoint Spread: 8.35.20151.0
As for ServiceStack - the 4.5.13 version we currently use is not a Nuget release, but their MyGet release - so the binaries for that change frequently - when they've digested the changes necessary for the recent release of .Net Core 2.0 / .Net Standard 2.0 they'll likely publish a Nuget version either as 4.5.14, 4.6.0 or 5.0.0 - we're not going to wait for that, but if they do release before we do, we will attempt to use their latest version (provided it doesn't introduce issues for us).
I'm afraid I can't be more specific than that - I really would prefer us to release with a version of ServiceStack from Nuget over their MyGet - but we've set ourselves a target for 7.1 to be released publicly by the end of September 2017, so if we have no stable newer version of ServiceStack before then it will be 4.5.13.
We might get a tad grouchy over the next 5 weeks as we try to focus on the 7.1 release
Mike
