Chrome 5.0.376.86, the stable version of Chrome released Thursday for Windows, Mac, and Linux, extends the plug-in to the mainstream version of Google's browser. Previously it was only in the developer and beta releases, and because of some hiccups it was disabled for a time there.
The new version also fixes five security bugs, including one involving a cross-site scripting vulnerability that had been fixed earlier but that recurred.
Flash has been a dominant component for building the richer aspects of the Web, notably games and streaming video, and programmers have relied on it to bridge compatibility and feature differences among browsers. But browser makers have long chafed at how Flash programs could crash the browser and confuse its user interface, and long-running work to reproduce many Flash abilities in Web standards is steadily maturing.
