  65
  66 == Upgrading ==
  67 1.31 has several database changes since 1.30, and will not work without schema
  68 updates. Note that due to changes to some very large tables like the revision
  69 table, the schema update may take quite long (minutes on a medium sized site,
  70 many hours on a large site).
  71
  72 Don't forget to always back up your database before upgrading!
  73
  74 See the file UPGRADE for more detailed upgrade instructions, including
  75 important information when upgrading from versions prior to 1.11.
