I'm sorry, but aren't we in the deep freeze phase of Jessie? What's your plan exactly? Release a new package in Debian Experimental? Even if you do that, I don't think it's a good idea to do it now. People (like me) are uploading to Experimental because they can't do it in Sid, so having a new package in there may break things. Can't you update lockfile after the release of Jessie? Also, could you give a brief sum-up of the API breakage between <<9 and >= 9? Would it be possible to work with upstream to avoid such breakage? It doesn't seem reasonable at all to me to have API breakage in a small 500 lines library containing only 12 classes and 26 methods, while the Linux kernel (which is far more complex) doesn't break the userland at all, as a rule. I believe it's our role as a distribution to work with upstream to avoid such craziness. Maybe upstream doesn't understand the importance of a stable API, and it would be worth explaining how bad such breakage is. What is your view here?
