About two weeks ago Microsoft released a KB update for developers, updating the runtime assemblies (from 8.0.50727.762 to 8.0.50727.4053).
That caused everything we built in the last few days to require the new libraries, failing run if they did not exist.
This caused a mess and confusion, since without any notice - our QA (not receiving the automatic update) and developers who did not yet receive the update - could not run our products.
Only after some frantic investigation the problem was diagnosed and corrected by supplying all non-developers the new redistribution package containing the new revisions of the runtime assemblies.
Now, putting frustration aside, I really would like to know what you think is the "by the book" way of notifying about such cases. Since most of our developers receive 'silent' automatic updates, there was absolutely no way of guessing what was about to happen. Even our deployment engineer didn't receive the appropriate InstallShield redistributables.
