The signature of I2PControl has been changed, as a result it wont auto update from version 0.0.1/0.0.2 to 0.0.4.
A manual remove and reinstall is needed to move from 0.0.1/0.0.2 to 0.0.4.
If you are using 0.0.4 this does not affect you.
I2PControl has been ported to Jetty6 as I2P is no longer including Jetty5.
Any feedback is welcome on the I2P forums I'm also reachable on the I2P irc.
