 New features
 ~~~~~~~~~~~~
+OpenWrt Barrier Breaker
+-----------------------
+Switching to the new OpenWrt release 14.09 ("Barrier Breaker") has yielded
+lots of updates for both the kernel and most packages. Besides better
+performance, this has also greatly improved stability (far less out-of-memory
+issues!).
 
 Modular config mode
 -------------------
+The old ``gluon-config-mode`` package has been split into five
+small packages, each providing a single section of the config
+mode form. This simplifies removing or replacing parts of the wizard.
+
+See the *Site changes* section for details.
+
+Experimental support for batman-adv compat 15
+---------------------------------------------
+As batman-adv has broken compatiblity starting with batman-adv 2014.0
+(bumping the "compat level" to 15), Gluon users must decide which
+batman-adv version to use. The package for the old batman-adv version
+``gluon-mesh-batman-adv`` has been renamed to ``gluon-mesh-batman-adv-14``,
+the new version can be used with ``gluon-mesh-batman-adv-15``.
+
+Please note that batman-adv compat 15 still isn't tested very well
+(and there are known bugs in the current release 2014.3), so for now
+we still recommend using compat 14 in "production" environments.
+
+fastd v16
+---------
+Besides other new features and bugfixes, fastd v16 support the new
+authentication method "UMAC". We recommend switching from the old
+``salsa2012+gmac`` and ``null+salsa2012+gmac`` methods to the new
+``salsa2012+umac`` and ``null+salsa2012+umac`` as UMAC is
+much faster and even more secure than GMAC.
+
+Private WLAN
+------------
+The new package ``gluon-luci-private-wifi`` allows to configure a private WLAN
+with WPA-PSK in the expert mode which is bridged with the WAN uplink.
 
 Bugfixes
 ~~~~~~~~
 
+* Expert Mode: Fixed all SSH keys being removed when a password was set
+* ``gluon-mesh-vpn-fastd``: Fixed VPN peers removed from the ``site.conf`` not being removed from ``/etc/config/fastd``
+* TL-LINK TL-WDR3600/4300: Added workaround for reboot issues
+* Improved stability (due to switch to OpenWrt Barrier Breaker)

 Internals
 ~~~~~~~~~
-* We're on Barrier Breaker now!
+The switch to Barrier Breaker has led to a multitude of changes all over Gluon:
+
+* The config mode/setup mode is now started by an own set of init scripts in ``/lib/gluon/setup-mode/rc.d`` run by procd
+* Many tools and services used by Gluon have been replaced by our own implementations to reduce the size of the images:
+
+  - ethtool has been replaced by our minimal Lua library *lua-ethtool-stats*
+  - tc has been replaced by our minimal implementation *gluon-simple-tc*
+  - radvd has been replaced by our minimal implementation *gluon-radvd*
