The rule that allows characters to be Lawful Evil if they are members of the Zhentarim or Lords' Alliance has been dropped, suggesting that evil characters are no longer legal in AL.
Also, the 'Creating a Character' section specifically states that you create a new level 1 character "for use in this season" (p.2), and that you cannot play adventures outside the current season content until you reach tier 2, at which point you are forbidden from returning to season 10 content (p.4), "Breaking from Seasonal Play").
I'm looking at the v10.0 document available directly from the WotC site, so if the version on the DMs Guild is a later version, some or all of the above may have already changed.
