jQuery Forum

We only offer custom downloads of our latest legacy release and our latest stable release. As of today those are 1.7.3 and 1.8.16. You should not be concerned that the book you are reading was printed when the latest stable release was 1.8.9 and since then there have been 7 more releases on the stable branch. Stable means we only fix critical bugs and don't add new features, so you can rest at ease using the latest version. That's been true of the largest .X numbered 1.8.X release ever since the 1.8 release came out. Every 1.8.x release since then has been better and more stable than the last.
