CPU Architecture and OS
^^^^^^^^^^^^^^^^^^^^^^^
A 64-bit CPU and 64-bit OS is required for Nextcloud 26 and higher.

The following is currently required if you're running Nextcloud together with a MySQL / MariaDB database:
* InnoDB storage engine (MyISAM is not supported)
* "READ COMMITTED" transaction isolation level (See: :ref:`db-transaction-label`)
* Disabled or BINLOG_FORMAT = ROW configured Binary Logging (See: https://dev.mysql.com/doc/refman/5.7/en/binary-log-formats.html)
* For **Emoji (UTF8 4-byte) support** see :doc:`../configuration_database/mysql_4byte_support`
