- “|Percona XtraBackup| couldn't be built with *Bison* 3.0. Bug fixed
    :bug:`1262439` (*Ryan Gordon*).”
    The patch for that bug was authored by someone else. It’s a bit hard
    to track who exactly, let’s just not mention any names. I hope the
    real contributor will excuse us for such a simple patch :)

- “introduced in |MySQL| 5.6.16 could” – unnecessary “could”.

Otherwise approved.

+============================
+ |Percona XtraBackup| 2.1.9 
+============================
+
+Percona is glad to announce the release of |Percona XtraBackup| 2.1.9 on May 7th 2014. Downloads are available from our download site `here <http://www.percona.com/downloads/XtraBackup/XtraBackup-2.1.9/>`_ and :doc:`Percona Software Repositories </installation>`.
+
+This release is the current GA (Generally Available) stable release in the 2.1 series.
+
+New Features
+------------
+ 
+ |Percona XtraBackup| has now been rebased on |MySQL| 5.6.17.
+ 
+ |Percona XtraBackup| package is now available for *Ubuntu* 14.04.
+
+Bugs Fixed
+----------
+
+ |Percona XtraBackup| couldn't be built with *Bison* 3.0. Bug fixed :bug:`1262439`.
+
+ The xtrabackup binaries now recognize a new :file:`my.cnf` option, :option:`open_files_limit`. The effect is the same as for the server: it changes the maximum number of file descriptors available to the xtrabackup process. The actual limit depends on the platform and ``ulimit`` settings. Bug fixed :bug:`1183793`.
+
+ If a remote |InnoDB| tablespace got CREATEd or ALTERed during the backup, an attempt to prepare such a backup later would lead to |Percona XtraBackup| crash. Bug fixed :bug:`1291299`.
+
+ Code in both |innobackupex| and |xtrabackup|, that was supposed to make sure no child processes are left running in case |innobackupex| got killed or failed with an error, relied on the fact the ``SIGTERM`` and ``SIGINT`` signals were not blocked by the xtrabackup process. However, both ``SIGTERM`` and ``SIGINT`` might be blocked by the process that had invoked |innobackupex|, for example, by the |Percona XtraDB Cluster| server processes doing an SST, in which case they were also blocked by the xtrabackup process, since the signal mask is inherited by child processes. Fixed by replacing ``SIGTERM`` in |innobackupex| and ``SIGINT`` in |xtrabackup| auto-termination with ``SIGKILL``. Bug fixed :bug:`1294782`.
+
+ A new table flag in the |InnoDB| data dictionary, introduced in |MySQL| 5.6.16, wasn't recognized by |Percona XtraBackup| which lead to ``InnoDB: in InnoDB data dictionary has unknown flags 50.`` warnings. Fixed by rebasing |Percona XtraBackup| on |MySQL| 5.6.17. Bug fixed :bug:`1302882`.
+
+All of Percona's software is open-source and free, all the details of the release can be found in the `2.1.9 milestone <https://launchpad.net/percona-xtrabackup/+milestone/2.1.9>` at Launchpad.
