Live.com is out of beta!
So if you've been holding back on creating a gadget for fear of breaking changes, you should now be able to merrily develop away knowing that you are working against a fully productionized system.
Dont think that this means we've stopped working on live.com - we haven't, but you can expect to see fewer changes and when changes are done you should get clarity around what we are changing and why.
Don't forget if you want to start developing for live.com you need to start at http://dev.live.com.
Update: search.live.com is also out of beta and is now a short URL to the search only interface of live.com (click Personalized page to go to your personalized live.com page).
