eXist

This release fixes many instabilities and database corruptions that were still present in the previous version. The XUpdate implementation should now have reached a stable state. Concurrent XUpdates are fully supported. The XQuery implementation has matured, adding support for collations, computed constructors, and more. Module loading has been improved, allowing more complex Web interfaces to be written entirely in XQuery (see the new admin interface). Finally, there's a new WebDAV module, a reindex/repair option, and support for running eXist as a system service.

This release adds support for XQuery 1.0,
including static type checks, modules,
constructors, Java binding, dynamic execution, and
many extension functions. The new XQueryServlet
and XQueryGenerator for Cocoon provide a simple
way to write entire Web applications in XQuery. In
addition, the release contains many bugfixes,
improved locking and caching strategies, and
support for binary resources.

This is the first official release with support for XUpdate.
Much effort has been invested to ensure that other
character encodings than Latin 1 are correctly
processed by the database as well as the query engine.
This applies in particular to East Asian languages and
scripts. Important missing parts of the XPath spec have
been implemented, more synchronization and
database corruption issues have been addressed,
interfaces have been improved, and dozens of bugs
were fixed.

This release fixes many bugs found in 0.9, including eof exceptions, out-of-memory errors, and corrupted database files. It also adds further performance optimizations with respect to indexing and querying speed. New features include the highlighting of search terms in query results, simpler database startup, access to index information, new Cocoon examples, and an IzPack-based installer.

This release fixes two of the remaining weak points of eXist, indexing
performance and scalability. Storing more than just a few megabytes
in a single database collection is no longer a problem; index files
consume less disk space, and indexing speed has improved by an order of
magnitude. New features include support for user authentication,
access control, and basic XInclude on the server.
