The jQuery developers have just released an update, version 1.1.3.1, which it claims to have significant speed improvements over the previous one. With several bug fixes and improvements, the package is reportedly 800% faster than before, a huge performance jump if their metrics are indeed accurate.

jQuery has slowly grown in adoption rate as more projects are now considering it as an alternative to Prototype, an equally powerful Javascript library. With point releases that come often and significant improvements, the package is now becoming a common part of most open source projects, perhaps attributed to its ease of use compared to other libraries.
