Google’s developer conference today in San Francisco is seeing the company offer a range of announcements across its products. Here’s your quick guide to the news, which we’ll be updating Wednesday and Thursday. The freshest news is at the top:

App Store for the Web: Google is putting together a directory of web apps called Chrome Web Store, though no launch date was specified. The apps will be mostly HTML 5 but will include Flash as well. App makers like TweetDeck have made HTML 5 versions that access APIs for notifications and geo-tagging in the browser, acting much like native clients. Google is working with Unity Technologies on Native Client to help transfer rich immersive 3-D games in the browser.

Open Video: Google released WebM, an open media format for the web-based on VP8, the codec it acquired along with On2. NewTeeVee had scooped this news more than a month ago, and has the full story today. Mozilla and Opera are on board to support the new format, and YouTube is converting its entire catalog. Adobe’s Kevin Lynch said VP8 will be included in Flash. Also on the video front, Clicker demoed a living room-ready version of its online TV guide, built with HTML 5.

Wave for Everybody: The collaboration tool Google Wave, which was introduced at last year’s I/O, is now part of Google Labs and doesn’t require an invite. “If you tried Google Wave out a while ago, and found it not quite ready for real use: now is a good time to come back for a second try,” product manager Stephanie Hannon wrote in a blog post. Wave is also being added to Google Apps.

Google Contextual Gadgets: Third parties can now build dynamic widgets into Gmail for businesses using Google Apps. Launch partners include Gist (see our WebWorkerDaily writeup), Kwaga (imports your correspondents’ social network profiles) and AwayFind (sends push notifications/alerts for important messages). Plus, Xobni announced developer tools to help any contextual gadget developed for Gmail work in Outlook.

Google App Engine For Business and VMware Love: App Engine gets enterprise level support, and later this year will have a SQL database so Google can entice corporate customers to build their in-house applications on App Engine for Business as opposed to on Microsoft Azure or other platforms as a service. It also has optimized App Engine to work with VMware’s Spring Source Java framework. Apps built in the Spring framework will now run on App Engine, VMforce, Amazon’s Web Services and other clouds that support Java.
