Windows: The latest beta release of Google's Chrome browser ups its dynamic page building speed by quite a bit. What users are really going to notice, however, is the built-in bookmark syncing, a feature previously available in bleeding-edge development builds.
If you grab the beta of Chrome 4, either as a version upgrade from Chrome or a new install, you'll get an option in your "wrench" menu to synchronise bookmarks, enabled through your Google account. We've shown you this feature when it was an optional switch, but this feature looks to make it into the final build of Chrome's Windows release.
Google touts Chrome's DOM Core speeds (i.e. jQuery powers) at its blog post, continuing in the tradition of browser makers constantly changing their speed metrics. The other big change users might notice is that extensions are disabled in the latest beta build, as the developers are said to be reworking the add-on framework. If that sounds like a reasonable trade for more dynamic page speed and bookmark syncing, Chrome 4 Beta is a free download for Windows systems only.
