1998 was the shift to the new rounded hood design, which is preferable to the old pointy-hood design because Campagnolo discontinued the small springs which eventually break on those apart from the G-springs.
2000 ten cogs
2001 and newer 9 speed shifters use the 10 speed derailleur geometry with its increased actuation ratio (tension adjustment on lower pivot).
2007 - 2008 shifters at the Centaur level and below got the much maligned Escape mechanism that only shifts one cog smaller per lever actuation
2009 brought us 11 cogs and Ultrashift, although early 2009 10 cog units have weak detents
2010 was the last year of 10 cog Ulrashift
2011 brought us PowerShift which is Escape with a catchy new name and the new Ultrashift hood shape
