No but it will be once merge the 5.6 branch. Yes:
/percona-server/bug1247096$ bzr file-id 5.5/doc/
psversionscompa
/percona-server/bug1247096$ bzr file-id 5.6/doc/

Done.

8 | +.. note:: |
9 | + |
10 | + This feature has been deprecated after |Percona Server| :rn:`5.5.28-29.2` and it is not available in |Percona Server| 5.6, because the `innodb_checksum_algorithm <http://dev.mysql.com/doc/refman/5.6/en/innodb-parameters.html#sysvar_innodb_checksum_algorithm>`_ feature in |MySQL| 5.6 makes it redundant. |
11 | + |
12 | Page sizes other than 16KiB |
13 | =========================== |
14 | |
15 | 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. |
16 | |
17 | +.. note:: This feature has been deprecated in the |Percona Server| :rn:`5.5.30-30.2`. It has been replaced by the `upstream <http://dev.mysql.com/doc/refman/5.6/en/innodb-parameters.html#sysvar_innodb_page_size>`_ version released in |MySQL| 5.6.4. |
18 | + |
19 | Relocation of the doublewrite buffer |
20 | ==================================== |
21 | |
22 | 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. |
23 | + |
24 | +.. note:: This feature has not been ported to |Percona Server| 5.6. |

- 10: s/will not be/is not comparison. rst identical to the current 5.6 extra_rseg. rst now mentions the variable removal twice.
- Is ps-versions-
version? Does it have the same bzr file-id?
- Should bug 1247094 be unlinked from the MP?
- innodb_
Probably we should keep only the "warning" one, i.e. the one
