Other expansions and adventures followed, as listed below. Upon the release of 3rd Edition, Planescape, along with most other settings, were discontinued, although fan sites such as planewalker.com were allowed to continue to use the material and update it to the new edition. The 3rd Edition "Manual of the Planes", the 3.5 Edition "Dungeon Master's Guide", and the 2004 "Planar Handbook" also used the general layout of the planes and some of the details from the setting, including Sigil, but these are not part of the Planescape line. Similar material has surfaced in 4th Edition rulebooks, as the "Dungeon Master Guide 2" includes a section on Sigil. The 5th Edition Player's Handbook also contains a section explaining the planes and Sigil.
