Your application changes are no longer published live immediately.
This gives you the ability to iterate your app and explicitly publish
changes. Many of you have created a separate development version of your
app. You no longer have to do that.
As the developer of the app you always have a view into the development
version of your surface. When you are confident in your changes, you must
explicitly click "Publish Changes" in My Apps. Your changes
will then be published to the live version and installed users after a short
waiting period. You may still make changes to your app during this period
and you do not have to explicitly publish those new changes at that time and
the waiting period is not reset. However, we will be giving you the
ability to un-publish changes that have not gone live yet in case you change
your mind.
I know many of you aren't happy about a waiting period for changes to go
live, no matter how short the length, but it also allows us to spot check
changes. We will be experimenting with lowering the waiting period
dependent on your app statistics including the length of time it has been live
and it's usage, etc. Please provide us feedback; we really want to strike
the right balance of developer capability and security. We believe the
short waiting period until published changes go live is reasonable, but our
ears are open.
