Dear all, we are particularly proud to announce the release of BaseX 6.6, which was released for the XMLPrague conference. It offers many new features, such as: -- full support for Higher Order Functions, introduced with XQuery 3.0 (dynamic function invocation, inlined functions, etc.), -- native support of the EXPath ZIP and HTTP specifications and other new XQuery modules, -- a new COPY Command to clone existing databases, -- revised CSV and text importers for different encoding and XML formats, -- additional XQuery 3.0 features (decimal-format and context item declarations, formatting functions, etc.), and -- numerous speedups, reduced memory consumption and stability fixes for XQuery and XQuery Update operations. Feel free to download our new release from http://basex.org, or check out our project page at GitHub for the latest sources. All the best, Christian BaseX Team, 2011
