  * `fast_index_creation <http://www.percona.com/doc/percona-server/5.5/management/innodb_fast_index_creation.html>`_ (replaced by |MySQL| 5.6's `ALGORITHM= option <http://dev.mysql.com/doc/refman/5.6/en/alter-table.html>`_). 
  * :ref:`Fast InnoDB Checksum <ps55:innodb_fast_checksum_page>` has been deprecated after |Percona Server| 5.5.28-29.2 because the :variable:`innodb_checksum_algorithm` variable in |MySQL| 5.6 makes it redundant. If this feature was enabled, turning it off before the upgrade requires table(s) to be dump and imported, since it will fail to start on data files created when :variable:`innodb_fast_checksums` was enabled. 
  * :ref:`Handle BLOB End of Line <ps55:mysql_remove_eol_carret>` feature has been replaced by |MySQL| 5.6 `binary-mode <http://dev.mysql.com/doc/refman/5.6/en/mysql-command-options.html#option_mysql_binary-mode>`_ configuration option.
+ * |Percona Server| 5.5 implemented ``utf8_general50_ci`` and ``ucs2_general50_ci`` collations as a fix for the upstream bug: :mysqlbug:`27877`. These are now being replaced by |MySQL| 5.6 ``utf8_general_mysql500_ci`` and ``ucs2_general_mysql500_ci`` collations.

-.. _compatibility: 
-
-==============================================================
-Options that make XtraDB tablespaces not compatible with MySQL
-==============================================================
-
-Page sizes other than 16KiB
-===========================
-
-This is controlled by variable :variable:`innodb_page_size`. Changing the page size for an existing database is not supported. Table will need to be dumped/imported again if compatibility with |MySQL| is required.
-
-Relocation of the doublewrite buffer
-====================================
-
-Variable :variable:`innodb_doublewrite_file` provides an option to put the buffer on a dedicated disk in order to parallelize I/O activity on the buffer and on the tablespace. Only in case of crash recovery this variable cannot be changed, in all other cases it can be turned on/off without breaking the compatibility.
