This release contains the huge contribution made by Andrey Lomakin and Artem Orobets about the support of index against multiple properties. This means a totally rewriting of many parts of the underlying index infrastructure and 150+ new test cases! They spent months of work to release this contribution, so many thanks in the name of the entire community and end users :-)
Another great contribution by James Roper is the support of indexes against collections of values.
