    ๐Ÿ› Bug Fixes

    • XML serializer leaking memory

    • ๐Ÿ›  Fix problems with computed namespace construction
    • When loading XQuery modules dynamically, declared global variables were not analyzed properly

    • ๐Ÿ›  Fix broken XQuery Update for 'insert following'
    • ๐Ÿ›  Fix ArrayOutOfBoundsException querying doc with enclosed expression and fn:id function
