We've shipped VistaDB 5.0.5 – a rollup of defects reported in the last few months. Most of the issues were related to ASP.NET usage of VistaDB 5 but there's also a query fix in there and a change in how Pack works to use less memory. Packs may take longer in some cases where systems have a lot of memory but this approach is safer and runs consistently in less memory. It also eliminates a few lines of code that are not compatible with Xamarin or Unity, which is important as we work to get full out-of-the-box support for those environments.
You can read the full release notes for more details and of course download the latest release to upgrade. As a patch release it's free to all licensed users of VistaDB 5.0.
