• new --query parameter for directly passing a query rather than a query path.
• fixed a bug occurring with group by clauses on native DataFrames with complex aggregations
• new --shell-filter parameters for modifying the way the output is shown in shell mode (e.g. --shell-filter 'jq . -S -C' for pretty printing)
• new output formats: json (top-level strings will be quoted), tyson and possibility to indent with --output-format-options:indent yes
• new JSound validator page at localhost:/jsound-validator.html
• support for user-defined atomic types with JSound verbose syntax
• fn:concat is now correctly in the fn namespace
• When the materialization is reached and the count is unknow, it is no longer shown as the max long value.
