Hello,

we are pleased to announce a version 2.2 of the Sedna XML
database system

New (since the previous release 2.1):

  * Sedna now provides support for triggers natively based
on XPath/XQuery and
    the Sedna XML update language (see Sedna Programmer's
Guide for details)

- Improved diagnostic of dynamic errors in XQuery/update
statements

- Root privileges are no longer necessary to run Sedna on
Linux

- Bug fixes:
  * correct Sedna shut down on Windows restart

Important note: Databases created with previous versions of
Sedna will not work properly with Sedna 2.2. Please, use
