It is not every day that jQuery will launch new releases and it is quite a big thing for them to have a double launch. According to their press release, although it is not easy to launch two releases at the same time, however, they expect it to be convenient for them in the end.
Our main goal with these two releases is to synchronize the features and behavior of the 1.x and 2.x lines, as we pledged a year ago when jQuery 2.0 was announced. Going forward, we’ll try to keep the two in sync so that 1.11 and 2.1 are feature-equivalent for example.
The jQuery team have announced that users who already have the 1.9/2.0 level will not have a hard time using these new versions as they have many similarities. However, for users who are still using the older versions it is likely that they may need to follow the jQuery 1.9 upgrade guide.
You may ask, what can we expect from the newly launched jQuery 1.10.0 and jQuery 2.0.1? The goal was to have the features and functions of both 1.x and 2.x lines work together. Actually, this goal was announced by the jQuery team a year ago. If you are excited to know the highlights of the new jQuery releases you can find more information here.
