</div>
</div>
</div>
<div class="orderedlist">
<ol type="1">
<li>
<p>
Demonstrated in a sample app how to use thread-specific structures to associate a DB_EVENT_REP_PERM_FAILED event with the transaction that caused it. [#17686]
</p>
</li>
<li>
<p>
Replication Manager Preferred Master is a new option for 2-site replication groups. One site is the preferred master, which assumes the master role as much of the time as its availability permits. A preferred master replication group guarantees that transactions committed on the preferred master site will never be rolled back while also providing client failover. [#20230]
</p>
</li>
<li>
<p>
A new flag DB_FORCESYNCENV is provided for DB_ENV->close(), which forces flushing the memory mapped regions before unmapping them. [#21176]
</p>
</li>
<li>
<p>
A new API is provided to limit the Replication Manager incoming queue based on the amount of heap memory it uses. [#21481]
</p>
</li>
<li>
<p>
BLOB support is now available for environments configured for replication. [#22359]
</p>
</li>
<li>
<p>
A new version of DB_ENV->failchk() helps supports multi-process environments which use DB_REGISTER rather than a monitoring process. It is turned on with --enable-failchk_broadcast. [#22419]
</p>
</li>
<li>
<p>
Added support for Visual Studio 2012. [#22477]
</p>
</li>
<li>
<p>
CPU time needed for database backups is now reduced. [#22967]
</p>
</li>
<li>
<p>
Added BDB utilities for the Android platform. [#23079]
</p>
</li>
<li>
<p>
Added --enable-error_history support. This diagnostic tool prints a stack trace when a panic occurs. [#23119]
</p>
</li>
<li>
<p>
The new log configuration option DB_LOG_NOSYNC has been added to avoid flushing the transaction log in order to stabilize storage. This can be useful when durability across system crashes is unnecessary and all the transactions in the environment specify either the DB_TXN_NOSYNC or DB_TXN_WRITE_NOSYNC flag. This configuration setting may be made by DB_ENV->log_set_config() or a DB_CONFIG line "db_log_nosync [on|off]". [#23191]

</div>
</div>
</div>
<div class="orderedlist">
<ol type="1">
<li>
<p>
Fixed a problem with DB_LOCKDOWN which would cause an mlock error ENOMEM on some operating systems. [#21379]
</p>
</li>
<li>
<p>
DB_ENV->close() now detaches from the environment's mmap and shared memory regions even when a panic error (DB_RUNRECOVERY) has been returned. DB_ENV->open(DB_REGISTER) detects whether a panic has occurred in the environment. If so it returns DB_RUNRECOVERY. Prior to this, the panic state was not detected, which might have caused a hang. [#22805]
</p>
</li>
<li>
<p>
Ensure that the size of memory mapped backing files are a multiple of the system pagesize. Previously the files were aligned up to 8KB boundaries, which was not adequate for systems with a 64KB pagesize. [#23290]

</div>
</div>
</div>
<div class="orderedlist">
<ol type="1">
<li>
<p>
Fixed a bug where, after some rare multiple-site failure scenarios including transaction rollbacks, Replication Manager could have incorrectly determined that new transactions fulfilled the acknowledgement policy. [#16624]
</p>
</li>
<li>
<p>
Acknowledgements are counted more precisely when an unelectable client is first joining the replication group and also when a master has been set to be unelectable. [#20825]
</p>
</li>
<li>
<p>
If there is already a replication process running, do not require a flag value when calling DB_ENV->repmgr_start() to start a subordinate process. [#20980]
</p>
</li>
<li>
<p>
Fixed a bug that a site could not rejoin the replication group on Windows after being removed from the group. [#22460]
</p>
</li>
<li>
<p>
When a removed site rejoins a two-site replication group with DB_REPMGR_CONF_2SITE_STRICT turned off, defer its election so that the rejoining site does not prematurely elect itself master with only its own vote when the other site is already master. [#22683]
</p>
</li>
<li>
<p>
Fixed a bug where a Replication Manager subordinate process could fail its automatic takeover as the replication process because it is unnecessarily waiting for acknowledgements from other sites before the connections to these sites are properly established. [#22998]
</p>
</li>
<li>
<p>
Fixed a bug where a client synchronization could get stuck because certain error paths were failing to release an internal lockout. [#23169]
</p>
</li>
<li>
<p>
Fixed a bug where replication group-aware log archiving might have unnecessarily kept log files after certain connection sequences between sites. [#23420]

[#23469] The SQL ORDER BY command on the primary key of a table can in rare cases return the results out of order if an index search is used in executing the query. For example: Create a single column table. Insert two rows with identical values. A query on the row id and the column will produce results in a different order depending on whether an index is used.
