Table G.1. Browsers and their development versions

stalled side by side with stable or dev versions)
• Chrome Dev: http://mng.bz/XKev (can't be installed side by side with stable
or beta versions)

Internet Explorer has a much slower release cycle than the other major browsers, so there
isn't a regular snapshot available. Check http://ie.microsoft.com/testdrive/ for information
on any beta versions or release candidates available.

Opera: Beta and alpha versions are called Opera Next; get them here: ht-
tp://www.opera.com/browser/next/ Whether a particular Opera Next release is a beta or
an alpha depends on how close to the next release they're getting; closer to release and
they'll be betas.

Safari: There are no beta releases of Safari as such, but you can download a nightly ver-
sion of the WebKit rendering engine that powers Safari and use it within your existing Sa-
fari install: http://nightly.webkit.org/

The different browsers' development versions each use their own terminology. Table G.2
will help you to understand what to expect from each version.
