version 1.0
* Changes in the C++ API
* Removed ResultIterator class. All public API methods use simply
Iterator.
* Added a new class named ExternalModule.
This class must be used for registering external functions.
This change makes the external function API incompatible with
previous releases.
* Loading pre-compiled queries (using loadExecutionPlan) requires to pass
a SerializationCallback which is used for
retrieving registered uri resolvers or trace streams.
Moreover, the callback is used for retrieving ExternalModules
which have been used when compiling the query.
* Changed the append function in zorba::String to const. Now, the
function does not change the String itself, but returns a new
String. Furgthermore zorba::String::append can now handle other
zorba::String objects - not only const char*. Also the operators
+ and += are defined on zorba::String.
* Other language bindings (Java, PHP, python, ruby) also now use
simply Iterator; ResultIterator removed.
* XQC (C language binding) brought up-to-date with latest revision
of that spec (https://xqc.sourceforge.net).
* Resolving of modules is now enhanced by the so called "Zorba
Module Path". Moreover, multiple ModuleURIResolvers can be
registered in one StaticContext. See the documentation for more
information.
* Added static and dynamic context introspection modules.
* Added the excel library to the built-in modules.
Implemented the most used excel functions.
* Added the math library to the built-in modules (the namespace has
changed to http://www.zorba-xquery.com/modules/math)
* Pass the Static- and DynamicContext as parameter to the evaluate function
of external functions.
* The XQuery class got a setTimeout option that allows the user to set a
maximum running time of a particular query execution.
* The StatelessExternalFunction is now non-pure by default. There is
a new subclass called PureStatelessExternalFunction which should
be used instead. PureStatelessExternalFunctions don't have access
to the Static- and DynamicContext.
* Renamed XQuery::serialize to XQuery::execute. The new method also
implements the functionality of the XQuery::applyUpdates method
(which was removed).
* Added the serialize library to the built-in modules. The function
util:serialize-to-string has been removed.
* The DynamicContext can be used to pass arbitrary name-value pairs
to the evaluate method of external functions.
* Implemented CSV to XML converters. See csv2xml.xq module.
You can convert back and forth between CSV files and XML
or formated text files and XML.
* Changes in the email functionnality
* implemented smtp:send functions as external functions
* added support for MIME messages (Text in character sets other
than ASCII, Non-text attachments, Message bodies with multiple
parts, Header information in non-ASCII character sets)
* most of the runtime iterators and functions are generated
(see https://sourceforge.net/apps/mediawiki/zorba/index.php?title=Creating_New_Runtime_Iterators_and_Functions)
* improved exception messages raised by the serializer
* Json is now able to parse Unicode messages
* improved functionality for java, php, python and ruby bindings.
version 0.9.8-rev1 (2009.09.22)
* bug fixes
* fixed a crash caused by converting long integers (> 1024 digits)
to string
* the compile-only check reports the URI of the encapsulating
entity in it's error report (used for XQDT semantic checking)
* fixed 'for $x in () return $x/test' to return the empty sequence
instead of raising a static error
* fixed build using Xerces-C 3.0.1
* fixed build for Mac OS X 10.6 (Snow Leopard)
* improved error reporting in the command line utility
* improved detection of the installed version of Xerces-C (raise
an error if a wrong version is installed)
version 0.9.8 (2009.08.26)
* More XQuery Scripting Features
* default initialization for external variables
* block local variables
* XQuery 1.1
* Support for the "validation as TypeName" feature
* Changed the try/catch syntax as specified in XQuery 1.1 (except
the try- and catch expressions are ExprSingle and not Expr).
* Examples for the Java API
* Function library
* creating PDFs using XSL Formatting Objects (requires Java)
* util:parse function
* converter functions to/from JSON or JsonML and XML
* function for sending simple text emails
* the util:tidy function returns a node instead of a string.
* XQDoc module http://www.zorba-xquery.com/zorba/xqdoc-functions
* Added a loadProlog function to the static context.
* Added support for XQueryX and XQueryX Update
* Added compiled query persistence to the C++ API
(XQuery::loadExecutionPlan() and XQuery::saveExecutionPlan())
* Added a printPlan function to the XQuery class of the API.
* Added new option in the Zorba command line utility: compile-only,
parse-only, lib-module, print-errors-as-xml.
* Added two plan printing function (printPlanAsXML and
printPlanAsDOT) to the SWIG generated APIs.
* Implemented 'declare option': options are set in the static context.
* fn:trace can be disabled by setting the option
QName("http://www.zorba-xquery.org/option", "trace") to "disable".
* Changed the scripting syntax of the exit expression from 'exit
with' to 'exit returning'.This is due to an ambiguity in the
grammar (see http://www.w3.org/Bugs/Public/show_bug.cgi?id=6852
for more information).
* Added accessor functions for node items to the Item class in the
API (i.e. getChildren, getAttributes, and getNodeName).
* Added a UserException to the API which is raised if the user makes
a call to the fn:error function.
* UTF8 support for the lexer
* bug fixes and performance improvements
version 0.9.5 (2008.02.17)

* Windows packages include a zorba_simplestore.dll
* Improved error messages for regular expression processing
* Added functions to return an item instead of xs:string
* Added a new signature to zorba-util:random in order to be able to call
random within a loop and get different numbers each time.
* Corrected the types of some functions/operators (YM_DURATION or
DT_DURATION instead of DURATION).
* Now possible to pass empty sequence as collection URI.
* Now cURL is set to follow an infinite number of redirects.
* Added validate after update
* Fixed schema files without target namespace.
* Fixed notation cast.
* Added list and union item types to type manager cache
* Added validation tests for schema substitution groups
* Added message when error during update test driver.
* Added partial support for scripting (XQSE)
* Added support "default element namespace" schema imports
* Added support variable initializers that refer to forward variable
declarations.
* Various bug fixes and performance enhancements.
