Dirk Holtwick's Google Wave client Waveboard for the Mac has made some changes to its browsing engine to work with Safari 5. These changes, introduced in version 1.1, include exchanging support for 32-bit mode with support for 64-bit mode (Safari 5 is incompatible with Google Wave under the former). This in turn also means that the Google Gears plug-in, which requires 32-bit mode, is no longer supported by Waveboard - though Google itself is dropping support for the plug-in as HTML5 features become more common in browsers. Forthcoming changes are expected to include support for custom domains and the capability to host multiple accounts; to get these updates automatically, users can turn on "Include beta releases" under Preferences.
