Just warnings. The game takes action and uses the correct methods so there is no actual harm done, but gives notification that the methods used in the script will be no longer supported.
I tried a quick search for the post where this was explained by someone who knows what they're talking about, but came up empty. But anyway: If you want to rid yourself of all those deprecation warnings, put a logcontrol.plist in your AddOns folder with the following content
"Actually this is a common misconception... I do *not* in fact have a lot of time on my hands at all! I just have a very very very very bad sense of priorities."

True. But unless I've completely misunderstood the concept, deprecation warnings are really only useful to the OXP makers, since it just warns that it will stop working in the next version. For the regular player, not having the log cluttered with warnings-that-look-like-errors-but-really-isn't should be a Good Thing.
