Some of you want too much. Devs won't give you premature changelog, because it can backfire (i.e. it turns out that something isn't fixed when it has been announced as fixed). In addition, game is "heavy" as software product, it takes sometime to prepare a snapshots for testing, and you need to do enough changes so that snapshots will be worth a testing. You can't just handle a new snapshot to testers every time something small is fixed - it is not effective way to work.
What do you want from devs? I am sure they can write: "We are fixing game..." every week or day, but is that really necessary? They can't always give more details. Hoping for patch every week is a bit optimistic.
P.S. If programmer gets a list of task and required time for completion, but manager constantly asks to update him on progress in detailed manner, programmer can't usually work effectively. People don't like "are we there yet?" question to be repeated endlessly.
