I'm very excited to see CQ 5.3 generally available. Existing CQ customers can download their copy of CQ 5.3 on Daycare. If you are not an existing customer get in touch to get an evaluation copy.
This release is a combination of over 125 new features and 1250 enhancements. I'm very thankful for the collaboration with many of our customers and the great feedback we have received.
CQ 5.3 includes a release of CRX 2.0 - our implementation of the JCR 2.0 standard (JSR-283). The next release CRX 2.1 will be available as a stand-alone version.
