+
+Major changes
+-------------
+
+OpenWrt 19.07
+~~~~~~~~~~~~~
+
+Gluon v2020.1 is the first release to use OpenWrt 19.07. All targets
+therefore use Linux 4.14.166.
+
+batman-adv compat v14 removal
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Support for the long deprecated compat 14 version of batman-adv has been
+dropped. Communities still using this version should migrate to batman-adv
+using the scheduled domain switch.
+
+IBSS wireless mesh removal
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Support for the IBSS wireless protocol has been dropped. Communities
+still using IBSS are suggested to migrate to 802.11s using the scheduled
+domain switch.
+
+Performance enhancements
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+We install zram-swap by default on ``ar71xx`` devices with 8MB of flash
+and 32MB of RAM.
+
+Renamed targets
+~~~~~~~~~~~~~~~
+
+- The ``ipq40xx`` target was renamed to ``ipq40xx-generic``.
+- The ``ipq806x`` target was renamed to ``ipq806x-generic``.
+
+Status Page
+~~~~~~~~~~~
+
+- Gateway nexthop information has been added to the statuspage when batman-adv
+  is used. This includes its MAC address and prettyname as well as the interface
+  name towards the selected gateway.
+- The site name has been added to the statuspage. If the node is in a multidomain
+  setup it will also show the domain name.
+
+DECT button to enter config mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Many AVM devices don't feature a separate RESET/WPS button, therefore
+starting this release we support entering the config mode via DECT buttons.
+
+X86 partition size
+~~~~~~~~~~~~~~~~~~
+
+The x86 partition size has been reduced to fit on disks with a capacity of 128 MB.
+
+Bugfixes
+--------
+
+Autoupdater aliases
+~~~~~~~~~~~~~~~~~~~
+
+We have added several new aliases for autoupdater compatibility on
+the following devices:
+
+- Ubiquiti UniFi AC LR
+- Raspberry Pi
+
+Site changes
+------------
+
+site.mk
+~~~~~~~
+
+-  The ``GLUON_WLAN_MESH`` variable can be dropped, as 802.11s is
+   the only supported wireless transport from now on.
+
+Internals
+---------
+
+Linting Targets
+~~~~~~~~~~~~~~~
+
+Support for linter make targets was added.
+
+- ``make lint``
+- ``make lint-sh`` to only check shell scripts
+- ``make lint-lua`` to only check lua scripts
+
+These require the shellcheck and luacheck tools. The docker image has
+been updated accordingly.
+
+Continuous integration
+~~~~~~~~~~~~~~~~~~~~~~
+
+We have implemented continuous integration testing using Jenkins and thereby
+ensure that all lua and shell scripts are linted, that the documentation
+still builds and warnings are highlighted, and that Gluon still
+compiles, by testing a build on the ``x86_64`` target. We expect this to
+significantly improve the feedback cycle and quality of contributions.
