 Zorba - The XQuery Processor
 
-version 2.x
-
-  * Custom Full-text thesaurus.
-  * Fixed bug #3401971 (node-by-reference on dynamic collections)
+version 2.5
+
+New Features:
+  * fn:available-environment-variables
+  * fn:environment-variables
+  * fn:uri-collection
+  * fn:unparsed-text
+  * fn:unparsed-text-available
+  * Extended API for Python, Java, PHP and Ruby.

+
+Optimization:
+
+Bug Fixes/Other Changes:
+  * Fixed bugs #931501 and #866987 (improved error messages for fn:format-number(). Additionally, the function now throws the FODF1310 error instead of XTDE1310, as the 3.0 spec requires)
+  * Fixed bug 955170 (Catch clause with URILiteral-based wilcard NameTest)
+  * Fixed bug 955135 (err:XQDY0044 not caught by try-catch expressions)
+  * Fixed bug #986075 (encountering flwor expr with no clauses; due to common 
+	  subexression being formed when inlining var in if-then-else expression) 
+  * Fixed bug #967864 (var substitution did not update theFreeVars property)
+  * Fixed bug #891650 (context size var not always declared within path expr)
+  * Fixed bug #948879 (--uri-path doesn't work with fetch:content())
+  * Fixed bug in window iterator (binding the end vars in the output tuple stream)
+  * Fixed bug #866547 (protect index-join rule from general flwor)
+  * Fixed bug #867253 (cdml:delete-nodes should only remove root nodes)
+  * Fixed bug #967428 (do not hoist index creation outside a try-catch)
+  * Fixed performance problem with the findNodeSources function of the no-copy rule
+  * Fixed bug #872234 (prevent a rewritting to take place in case of sequential expr)
+  * Fixed bug #906494 (default compile with D_FILE_OFFSET_BITS=64)

+  * Fixed bug #981405 (do not hoist expr containing try-catch variables out of the
+          associated try-catch expression)
+  * Fixed bug #947627 (throw XQST0099 if more than one declarations of context item
+	               type in same module)
+  * Fixed bug #980526 (no-copy rule bug due to global var being set in "distant" udf)
+  * Fixed bug #949910 (has-children may be invoked on all nodes). Internally, zorba::store::Item::getChildren() now returns NULL on node classes without offspring (instead of raising an error).

+  * New URI module providing percent-decoding functions.
+  * The core parse-xml module is now able to parse input files in a streaming mode. A number of new options have also been added.
+  * LibXml2 version 2.7.0 or higher is now required in order to build Zorba.  
+  * Added index management function to the C++ api's StaticCollectionManager.
+  * Added createDayTimeDuration, createYearMonthDuration, createDocumentNode, createCommentNode, createPiNode to api's ItemFactory.

+  * Add new XQuery interface for the PHP bindings.
+  * Added two API methods StaticContext::getFunctions to introspect the functions of a static context
+  * Added API method Item::getNamespaceBindings().

+
+
+Optimization:
+  * No-copy optimization: avoids copying nodes during node-constructor expressions.
+  * Added external function annotations %ann:propagates-input-nodes and 
+    %ann:must-copy-input-nodes to be used by the no-copy optimization.
+  * Caching of results for recursive functions with atomic parameter and return types.
+  * Added %ann:cache and %ann:no-cache to enable or disable caching of results of functions with atomic parameter and return types.
+  * Types-related optimizations for runtime operators (comparisons, FnBoolean, Or, And,
+    Compare, instance-of, cast, castable, treat, promote).
+  * More efficient implementation for base64Binary items
+  * Preallocate and reuse temp sequence iterator for LetVarITerator
+    and CtxVarIterator.
+  * Enhanced push-down of positional predicate into LetVarITerator
+    and CtxVarIterator.
+  * Change the implementation of the free-vars annotation and got rid
+    of the annotations map in expressions.
