> existing apps won't be able to update to new APKs using older SDKs starting in November So, some developers will probably defer handling the changes until November, and then if there is some critical bug (security or otherwise) they won't be able to just fix the bug without also building the rest of the app with the new SDK as is, broken/untested even if it compiles?
