Documentation updated; now includes documentation for the XQuery function library, for the Java API and for the Solr-based REST API.
Fixed some over-optimization bugs; one was related to path queries generated from paths with predicates in them, and another one was related to let clauses in flwor expression.
Fixed a thread-safety issue where the solr index wouldn’t be closed properly in the presence of a lot of concurrent indexing requests, leading to lock exceptions.
Enhanced the optimizer with better support for variables and FLWOR expressions. It now maintains a variable reference map so that it’s possible to more fully optimize expressions containing variables. Also, constraints from for and where clauses are now taken into account when optimizing.
The app-server now includes the connect4 app
