• recreate password if missing during upgrade
• fixed issue #1126
• fixed non-working subquery index optimizations
• do not restrict summary of Foxx applications to 60 characters
• fixed display of “required” path parameters in Foxx application documentation
• added more optimizations of constants values in AQL FILTER conditions
• fixed invalid or-to-in optimization for FILTERs containing comparisons with boolean values
• fixed replication of _graphs collection
• added AQL list functions PUSH, POP, UNSHIFT, SHIFT, REMOVE_VALUES, REMOVE_VALUE, REMOVE_NTH and APPEND
• added AQL functions CALL and APPLY to dynamically call other functions
• fixed AQL optimizer cost estimation for LIMIT node
• prevent Foxx queues from permanently writing to the journal even when server is idle
• fixed AQL COLLECT statement with INTO clause, which copied more variables than v2.2 and thus lead to too much memory consumption. This deals with #1107.
• fixed AQL COLLECT statement, this concerned every COLLECT statement, only the first group had access to the values of the variables before the COLLECT statement. This deals with #1127.
• fixed some AQL internals, where sometimes too many items were fetched from upstream in the presence of a LIMIT clause. This should generally improve performance.
