testing and fixing 2.2 support was a real pain at the end of the 2.7.0 cycle. It also adds a lot of cruft in the drivers and adds to patch misery. What do you think of removing 2.2 support and making 2.7.0 the last 2.2-compatible release? For reference, we dropped 2.0 support in release 2.5.0, March 2000. mds
