As an update to an article we posted recently about Valve seeming to need confirmation of release date changes on Steam, Valve have now confirmed this.
If you're not keeping up and to save you a quick click: Some developers were constantly changing their release date, even if they had no intention of releasing on that new date. It affected pages like the upcoming releases list and made their games always show up near the top.
Now, in a blog post on the Steamworks Development group, the Valve developer confirmed the recent change was made to address "developers that intentionally or unintentionally changed their release dates multiple times". This should hopefully make it less annoying for both players and developers, as it had been a problem for quite some time.
Additionally, Valve will now be sending email reminders to all developers when it's coming up to two weeks before their currently set date. Previously, Valve were only sending this out to a small set of games "as a test" but now every developer will get it.
