I've opened a ticket to drop support for Python 2.5 *after* our next release: http://twistedmatrix.com/trac/ticket/5553 If this would be a major problem for you please comment on the ticket; just to clarify, regardless of the ticket's resolution the next release (12.1) will continue to support Python 2.5. -Itamar
