The album was released by EMI and Harvest on the then-new compact disc format in Japan in June 1983, in the US and Europe in August 1984, and in 1992 it was re-released as a remastered CD in the box set "Shine On". This version was re-released as a 20th anniversary box set edition with postcards the following year. The cover design was again by Storm Thorgerson, the designer of the original 1973 cover.
