As planned a regular maintenance release of the framework is available!
qooxdoo 1.6.1 includes over 110 bugfixes. It is backwards compatible to the previous 1.6 release, i.e. nothing needs to be changed in your existing apps, if they are based on qooxdoo 1.6.
Download version 1.6.1. Checkout the detailed release notes and the manual.
Many thanks from the core developers to the community of contributors and users.
Enjoy! 
PS: A new major release qooxdoo 2.0 is also to be released today. As its name suggests, and unlike the maintenance release 1.6.1, it comes with many substantial improvements and exciting new features …
Just re-built two of our main applications (previously on 1.6). What a boring exercise, it just worked!
