Among the news are "Added IP Filter functionality." and "Database encryption improved".
There is also an interesting white paper describing how the security works with this SaaS (Software as a Service) solution.
For all news in SourceAnywhere Hosted see the news section on Dynamsoft's website.
One thing I noticed after upgrading and when starting the application was a Global Message telling about that a new version is available. It would be better if it knew what version I have installed.
Other than that SourceAnywhere Hosted is really useful when you collaborate with an extended development team. I recommend you to give it a try.
