Hello derby-dev,

I would like your feedback on the release announcement which I will post to various mailing lists.

Thanks for putting this together, Rick!  One minor comment:

 o XPath/XQuery support has been improved.

Technically speaking, XPath/XQuery wasn't officially supported before 10.2. There was code in Derby 10.1 but the operators were unofficial/"experimental" because the SQL/XML spec that they are based on was still in flux at that time. That's why the operators and datatype were not documented before now.

With 10.2 we're making support for an XML datatype and corresponding operators "official" by documenting it and claiming that, insofar as we know, the operators are now in line with SQL/XML and are ready for production use. Perhaps most importantly this means that future releases of Derby XML support should now pay attention to backward-compatibility concerns so that any apps that use XML with 10.2 will also work with XML in future releases. (There was no such guarantee with XML in 10.1).

All of that to say that maybe instead of "has been improved", we could write something like:

  o New XML datatype and operators for storing and querying XML data.

If that's too confusing for people ("Wasn't there already an XML type in 10.1??"), we could perhaps add a short explanatory note, something like:

  o New XML datatype and operators for storing and querying XML data.
    (not officially supported in earlier releases).
