Much as I (we) understand your need for information on the next update, it is not possible to do so for a variety of reasons. No one understands better than us your need for fixing a bug that is bothering you. But when we do that, we want to make sure that the other person who needs a different fix is also taken care of.
In an unrealistic world, the bug fix would sneak your way into your software the next time you opened it and an equally sneaky message would inform you about the transgression.
In the world as it exists today, product teams usually have to co-ordinate a lot of things and make sure things are perfect before they announce a release date. And things could go terribly wrong at the last minute prompting a change of plans. That is how everyone’s world works too, right?
This is the reason why the product management team is the only team that has to make that call and announcement. People like me can broadcast it only after that is done. Think of it like a nuclear deal signed by the head of your country. The journalists probably have a clue about the details but they are not authorized to reveal it until the deal is done. There can be consequences.
