Google's developer conference yesterday in San Francisco offered a range of announcements across the company's products. (Conference updates for today still awaited)

Two more API additions: The Google Feed API now includes push updates, as well as a bunch of new open source web fonts and a font API.

Google Buzz Fills Out APIs: Google Buzz launched an API that will allow developers to access user feeds, search updates, post updates and more. It's already been integrated by Seesmic, Socialwok and other partners.

Google Latitude Gets an API: Google is allowing developers to build on its mobile location service — with the very explicit permission of users. The team has some cool app and service ideas here.

PayPal for Android: PayPal is offering developers the option to use its Mobile Payments Library to enable purchases in their Android apps. It already does this for the iPhone.

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.

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 3D 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.
