Hi there, BaseX 8.6.6 is out. Among other things, we fixed two bugs in the map:merge function and where clauses with predicates, so we recommend you to update to the latest version if you work with BaseX 8.6.x. Apart from that, binary data handling was tweaked a lot: The Binary and Conversion Modules will now be much faster if you iterate over single bytes. Have fun everyone, Christian PS: I’ll be offline most of the time until Sep 15. Thanks everyone for keeping the mailing list alive!
