Updates

The Himalayan Database team publish new releases of the data a few times a year. Every release imported here is kept, so you can see exactly what changed between them — new expeditions and members, corrected records, and anything that was removed. Peak and expedition pages also have a change history link showing how that record has changed. Follow new releases with the updates feed, and see the data checks run on each release.

Older releases were recovered from archived copies of the database; the original 2004 CD-ROM edition and the seasons between surviving copies are not available, so some releases bundle several seasons of changes.
