It’s a wonderful day for a software release. Such a wonderful day, we’re doing two software releases! Today it’s jQuery 1.10.0 and jQuery 2.0.1 making their debut — five years to the day after jQuery 1.2.6 was released.
A simultaneous release isn’t always easy, but it can be very satisfying. The team is certainly satisfied with this duo of deliveries; those of you who have already upgraded to the 1.9/2.0 level should have an easy time with these versions. If you’re upgrading older code, the advice in the jQuery 1.9 upgrade guide still applies to these two releases as well. Also don’t forget that jQuery. 2.0 doesn’t support IE 6, 7, or 8 since we’re leaving that work to the 1.x branch. If you need some help updating or keeping older pre-1.9 jQuery code going, don’t forget about the jQuery Migrate plugin.
Kind of hard to believe that 1.2.6 is 5 years old. So many sites are still using it. I may incorporate 2.0 into some personal projects just so I can say I’m not supporting old IE, but that’s just me.
