ACTUALIZACION DE GOOGLE EARTH 5.1 (en ingles)

Update for Google Earth 5.1 released

Google Earth 5.1 (beta) has been widely regarded as a great update, with a much faster, more responsive interface. Being a beta release, though, means it's still got a few kinks to work out. Last night, Google pushed out an update to 5.1. Presumably, this latest release fixes some of the bigger issues. See below for one we know about.
It won't auto-update to this latest release, so you'll need to go to earth.google.com and download it for yourself. Downloading it from there will get you from version 5.1.3506.3999 to 5.1.3509.4636.
Perhaps more importantly, this will also upgrade your Google Earth plugin to the latest version. Some of you had issues with Al Gore's new COP15 tour that Google released yesterday, and this latest update seems to resolve the issues.
