Adobe Systems has announced that the latest version of the Flash plug-in, required to run most video content on the Web, is now available as a release candidate. Users of the Flash 10.1 Release Candidate for Windows, Mac, and Linux should see significant resource reduction while watching H.264 video and playing Flash-based games. Along with performance improvements, Adobe claims that the new version will drain your battery less.
Although smartphone support is anticipated this year in Flash 10.1, it won't be shipping just yet. The full list of changes to Flash made between the last beta and this release candidate is available as a PDF.
