Steam update news is not updated for every patch for every game. For example, Plants & Zombies had several recent updates - but those updates didn't have corresponding patch notes. This occurs often enough that I felt my original post was justified.
A different type of example of why I posted was with a few other types of update issues.
Where the most current patch isn't available on Steam for many months. Example: Sword of the Stars' last two patches were 3 and 5 months behind on Steam.
As well there are examples where a Steam version of a game doesn't really ever sync up with the non-Steam version. Example: Hearts of Iron III was both months behind on patching for a while and then when it did get patched on Steam, the checksum (which the game uses to sync multiplayer) wasn't the same on Steam as it was on non-Steam versions.
So I have to ask these questions. Hope you understand.
I don't mind a few days or week delays too much. I do mind not having the current game, especially for new content or bug fixes.
