 It is indeed due to running a previous beta in production.

 I was only able to reproduce it wit the following steps:

 1. Checkout Beta 2
 2. Start and save a post, leaving the editor open after saving.
 3. Checkout Beta 3
 4. Error occurs and frequently. A dialog is shown in the editor that the
 user is disconnected.

 If I closed the editor in step two, and reopened it after upgrading I did
 not receive any errors. For WordPress.org the errors should settle down
 once authors return to the post editors they've left open and close them
 due to the error message.

 I'll re-close this as fixed as it doesn't warrant a workaround.
