10 == Upgrading notes for 1.34 ==
11 1.34 has several database changes since 1.33, and will not work without schema
12 updates. Note that due to changes to some very large tables like the revision
13 table, the schema update may take quite long (minutes on a medium sized site,
14 many hours on a large site).
16 Don't forget to always back up your database before upgrading!
18 See the file UPGRADE for more detailed upgrade instructions, including
19 important information when upgrading from versions prior to 1.11.
