+Gluon 2019.1.1
+##############
+
+Bugfixes
+********
+
+* Fixes device alias for Ubiquiti UniFi AC LR. (`#1834 <https://github.com/freifunk-gluon/gluon/issues/1834>`_)
+  Autoupdates on this model were impossible before, since we were missing the proper device alias.
+
+* Add correct ath10k firmware package for OCEDO Koala. (`#1838 <https://github.com/freifunk-gluon/gluon/pull/1838>`_)
+
+* Fixes various batman-adv bugs with backports from 2019.4 and 2019.5 by updating the openwrt-routing packages feed.
+
+* Fixes node role list.  (`#1851 <https://github.com/freifunk-gluon/gluon/issues/1851>`_)
+  With Gluon v2019.1 it became impossible to change the role of a node via the config mode.
+
+Other Changes
+*************
+
+* Linux kernel has been updated to either
+
+  - 4.9.207 (ar71xx, brcm2708, mpc85xx) or
+  - 4.14.160 (ipq40xx, ipq806x, mvebu, ramips, sunxi, x86).
+
+Known issues
+************
+
+* Out of memory situations with high client count on ath9k.
+  (`#1768 <https://github.com/freifunk-gluon/gluon/issues/1768>`_)
+
+* The integration of the BATMAN_V routing algorithm is incomplete.
+
+   - | Mesh neighbors don't appear on the status page. (`#1726 <https://github.com/freifunk-gluon/gluon/issues/1726>`_)
+     | Many tools have the BATMAN_IV metric hardcoded, these need to be updated to account for the new throughput
+     | metric.
+
+   - | Throughput values are not correctly acquired for different interface types.
+     | (`#1728 <https://github.com/freifunk-gluon/gluon/issues/1728>`_)
+     | This affects virtual interface types like bridges and VXLAN.
+
+* Default TX power on many Ubiquiti devices is too high, correct offsets are unknown
+  (`#94 <https://github.com/freifunk-gluon/gluon/issues/94>`_)
+
+  Reducing the TX power in the Advanced Settings is recommended.
+
+* The MAC address of the WAN interface is modified even when Mesh-on-WAN is disabled
+  (`#496 <https://github.com/freifunk-gluon/gluon/issues/496>`_)
+
+  This may lead to issues in environments where a fixed MAC address is expected (like VMware when promiscuous mode is
+  disallowed).
+
+* Inconsistent respondd API (`#522 <https://github.com/freifunk-gluon/gluon/issues/522>`_)
+
+  The current API is inconsistent and will be replaced eventually. The old API will still be supported for a while.
+
+* Frequent reboots due to out-of-memory or high load due to memory pressure on weak hardware especially in larger
+  meshes (`#1243 <https://github.com/freifunk-gluon/gluon/issues/1243>`_)
+
+  Optimizations in Gluon 2018.1 have significantly improved memory usage.
+  There are still known bugs leading to unreasonably high load that we hope to
+  solve in future releases.
