When updating from 3.0.10 to 3.0.11-RC1, I get the following message on updating:
"Update files are out of date. The update files found are for updating from phpBB 3.0.10 to phpBB 3.0.11-RC1 but the latest version of phpBB is 3.0.10."

This should not be displayed when updating to a newer version than the most recently released version.

IRC Log:

<imkingdavid> can we remove the "Update files are out of date. The update files found are for updating from phpBB 3.0.10 to phpBB 3.0.11-RC1 but the latest version of phpBB is 3.0.10." when the version is > than "latest" version?
<Noxwizard> Versioncheck just needs to be updated.
<unknownbliss> he's saying that it is saying its out of date even though its later
<unknownbliss> probably should use version_compare, not checking if they are ===
<bantu> updates need the QA constant afaik
<bantu> imkingdavid: report that issue for 3.0.12-RC1
