This came out today in the UK, and is a well-written and detailed history of the band, covering all eras and releases. It has two covers - the first half of the magazine follows the band up to 1975, then you flip it over to the Rumours side for their history up to the present day.
There's a discography, album reviews, features on all the principal members, and an interview with the founder of the Fleetwood Mac UK website. It's definitely worth a purchase:
