Retirement of archives 55 and 56

Please note that the archive websites for Ensembl releases 55 and 56 (July and September 2009) will be retired this week when version 69 is released.

This is in accordance with our rolling retirement policy, whereby archives more than three years old are retired unless they include the last instance of the previous assembly from one of our key species (human, mouse and zebrafish).

For more information about how to use archives, please see our previous blog post on the topic; a list of all current archives is available on the main website.
