  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).
  15
  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.

  86 == Compatibility ==
  87 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
  88 supported, it is generally advised to use PHP 7.0.13 or later for long term
  89 support.
  90
  91 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
  92 but support for them is somewhat less mature. There is experimental support for
  93 Oracle and Microsoft SQL Server.
  94
  95 The supported versions are:
  96
  97 * MySQL 5.5.8 or later
  98 * PostgreSQL 9.2 or later
  99 * SQLite 3.8.0 or later
 100 * Oracle 9.0.1 or later
 101 * Microsoft SQL Server 2005 (9.00.1399)
