Version 3.4.0 of the PHP client was released on July 20, 2015 and is available for download here. It has the following features and fixes.
- Support for
nullas valid argument to a UDF (AER-4003).
- Prefer to always download the appropriate C client ahead of building the extension (AER-4001).
- Fixed Issue 48 - a new backward incompatible format for data returned by aggregate() (AER-3948). Thanks @arussellsaw!
