Previously, MySQL Server distributions included the MySQL Reference Manual in Info format (the Docs/mysql.info file). Because the license for the manual restricts redistribution, its inclusion in Community packages caused problems for downstream redistributors, such as those who create Linux distributions. Community distributions of MySQL Server no longer include the mysql.info file, to make the repackaging and redistribution process easier (for example, the source tarball and its checksum can be used directly). This change applies to all source and binary Community packaging formats. Commercial (Enterprise) distributions are unchanged.
For those who wish to continue using the MySQL Reference Manual in Info format, we have made it available at http://dev.mysql.com/doc/.
In debug builds, test case failures would occur due to
ibuf_contract_ext performing merges and
dict_stats_update returning evicted pages
back into the buffer pool while
ibuf_change_buffering_debug is enabled.
InnoDB failed to return an error when
attempting to run a query after discarding the tablespace.
When the change buffer is enabled,
failed to write a transaction log record when merging a record
from the insert buffer to a secondary index page if the insert
was performed as an “update-in-place”.

The storage engine was set incorrectly during a rebuild of a
partition; the table storage engine was ignored and the default
storage engine used instead. Thus, in MySQL 5.1, it was possible

the storage engine actually used by the table is checked and
used by the handler for the rebuild operation, so that the
partition storage engine is not inadvertently changed.
Replication: When an error encountered by the dump thread while reading events from the active binary log file was a temporary error, so that the dump thread tried to read the event, it was possible for the dump thread to seek the wrong position, which could cause one or more events to be resent. To prevent this, the thread's position is obtained after each correct read of an event.
In addition, with this fix, only binary logs that are not closed normally are marked as possibly being corrupted.
Finally, two warnings are added; these are now returned when a dump thread encounters a temporary error. (Bug #17402313)
