I have just published the radare2 0.9.6 packages for Debian in the Inguma Debian repository (http://deb.inguma.eu). They are in their way to the official archives, but due to several new packages, it will take them a while to reach unstable as they have to go through the FTPmasters' manual approval.
We have been using radare2 0.9 as the base API in Bokken (it was the latest packaged), for the past two years, and this new release breaks the internal r2 API in several ways, so Bokken is not able to load a single binary.
Over the course of the next few days I will be adapting the code to talk to radare again and to force specific versions of the API to make sure this is a less likely event.
See you in mercurial!
