I’ve been using the “nightly experimental” builds of Safari’s rendering engine (WebKit) on my home desktop for several months now. When I was prompted to install the new version tonight, it occurred to me that I haven’t worried about the stability of the builds since the second week I was running the nightly builds. Thinking a little more seriously about this, it’s amazing that I’ve probably run close to 45 different revisions of the engine and never had an issue with rendering glitches, stability or performance. That’s quality software in my book – especially as they have been working on a rewriting/re-factoring their new JavaScript engine during this period.

And it’s stable. Rock solid, even.
