Thanks all for the valuable feedback on our latest major release.

BaseX 12.1 is now available, with more new and revised features than planned.

Highlights include:

RESTXQ

• improved local locking for resources supplied via arguments

Storage

• PUT operations: replace or ignore existing resources

XQuery

• Cache Functions: Store transient data in main-memory LRU caches

• Key/Value Store: All opened stores are now kept in main memory

• faster generation and conversion of sequences and arrays

• fn:load-xquery-module: retrieve module only once at runtime

XQuery 4.0

• Function declarations: The 'local' prefix can now be omitted

• Destructuring: let $($head, $tail) := ...

• Map construction generalized: { 1: 2, $map-entries }

• Pseudo path function: $xml/get($node-name)

• New node comparators (is-not, precedes, follows, ...)

• %method annotation replace by =?> operator
