Google has released a new version, 24.0.1312.57, of its Chrome browser, for Windows, Linux, Mac OS X, and Chrome Frame. This appears to be a bug fix release, focused on two bugs (renderer crashes and microphone problems) on the Mac OS X platform, and a renderer problem with Chrome Frame. There do not appear to be any security fixes in this release; more details are in the Release Announcement.
Unless you are suffering from one of the bugs fixed in this release, I don’t think there is any reason for rushing to get the upgrade. (I do think that there is a lot to be said for keeping your system’s software up to date, within reason.) Windows and Mac users can get the new version via the built-in update mechanism; Linux users should check their distribution’s repositories for the new version.
