The CB Facebook Connect 1.3 plugin has just been released for all Advanced / Professional members.
Version 1.3 uses new API and also has a new 'no-conflict' mode to address other exensions loading the API before it.
All Professional and Advanced members can download this new version and just install over their existing environment for easy upgrade. No changes need to be made on the Facebook application side.
Version 1.2 can also be purchased as a one-time product purchase from our CB Add-ons page.
