We are glad to give you Version 9.4 of BaseX, our XML framework, database system and XQuery 3.1 processor:
We have focused on rewriting and optimizing complex XQuery code and speeding up your RESTXQ apps:
WEB APPLICATIONS - DBA: support for millions of log entries - LOGTRACE option: write trace output to logs or STDERR - rest:init: Full or partial initialization of RESTXQ cache - basexhttp: register job services
GUI - result view: show number of results and result size - Shift F4-F7: toggle search options (case, regeex, ..) - Ctrl-Shift-B: jump to matching bracket
XQUERY LOCKING - single lock option for reading and updating queries - Java bindings: annotation added for updating functions
XQUERY FUNCTIONS - convenience functions: json:doc, csv:doc, html:doc - element names: convert:encode-key, convert:decode-key - jobs:eval: option added for writing log entries - session module: only create new sessions if required
XQUERY PERFORMANCE - boolean comparisons: flatten nested expressions - boolean expressions: merge conjunctions - comparisons: simplify operands with if expression - database functions: always open at compile time - databases: propagate to more expressions at compile time - filters: inline context for single items - filters: rewrite to simple maps - FLWOR: inline where clauses into let clauses - FLWOR: merge last with return clause, rewrite to simple map - FLWOR: rewrite "return if ..." to "where ... return" - fn:for-each, fn:filter: rewrite to FLWORs and filters - if expression, EBV tests: simplify boolean tests - lists, sets, logical expressions: flatten expressions - lists: rewrite to union expressions - logical expressions: apply more boolean algebra rules - paths: remove redundant predicates - predicates with name functions: rewrite to name tests - predicates: merge expressions, discard redundant tests - predicates: remove of superfluous and redundant tests - set expressions: merge operands - simple map: inline cast expressions - simple maps: faster evaluation - simple maps: merge operands - simple maps: rewrite to paths, optimize for index access - switch: rewrite to if expression - types: skip redundant checks, promotions and conversions

Have fun, Your BaseX Team
