Mark Logic has released version 4.1 of their namesake XML database for Linux, Solaris, and Windows. New features in 4.1 include:
- SSL and HTTPS Support
- URL Rewriting
- xdmp:to-json and xdmp:from-json extensions functions that serialize
XQuery datatypes as a JSON string and vice-versa

- Search API With Support for Facets and Snippets
- W3C XML Schema Validation
- Function Values

Pricing's hidden, but seems to be in the ballpark of $60,000 as best I can tell.
