ExpressionEngine 2.1.0 Build 20100810 Security Update
Last week’s build release, 20100805, introduced a bug that in some circumstances could result in guests being recognized as a logged in member. We were able to identify and correct it quickly, and no database changes are involved. For that reason, we’ve released this as a simple build update rather than incrementing the version. If you downloaded and installed ExpressionEngine 2.1.0 between Friday the 6th and the morning of Tuesday the 10th, you should re-download and follow the simple build update instructions which will patch your system.
