##############
Major changes:
##############
Multicast optimizations (batman-adv):
In this release, we reenable the multicast optimizations, that have gone
through another round of bug squashing upstream. With this feature
batman-adv will distribute IPv6 link-local multicast packets via
individual unicast packets instead of flooding them through the whole
mesh as long as the number of subscribed nodes does not exceed 16. This
reduces layer 2 overhead, especially for IPv6 Neighbour Discovery.
We also relaxed the firewall for IPv6 multicast packets: Instead of
always dropping non-essential multicast packets we now allow all IPv6
link-local multicast packets to pass when the destination group has up
to 16 subscribers
Status page:
The status page has received much attention in this release and now
exposes many more details that help to understand a node's setup remotely.
Among other things, we now expose wireless client count per radio, the
mac80211 identifiers, the frequencies radios are tuned to, as well as
information about the VPN provider and details on the mesh protocol stack.
gluon-switch-domain utility:
The ``gluon-switch-domain`` utility has been introduced to allow for a
standard way to encapsulate the steps required for safely switching
between domains. Existing packages like the hoodselector and the
scheduled-domain-switch have been tied in with gluon-switch-domain.
It has an experimental ``--no-reboot`` flag that requires further
testing, to ensure it doesn't accidentally bridge separate domains.
##############
Other changes:
##############
- The private WLAN interface is now assigned the interface name
`wan_radioX` where X is the phy index.
- Linux kernel has been updated to 4.14.235
- The kernel's mac80211 stack has been updated to 4.19.193-test1 to
mitigate the `FragAttacks https://www.fragattacks.com/`_ vulnerabilities
- OpenSSL has been updated to 1.1.1l, fixing CVE-2021-3449 and CVE-2021-3450
- openssl: use --cross-compile-prefix in Configure
- Dropbear has been patched against mishandling of special filenames in
its scp component (CVE-2020-36524)
- kernel: bump 4.14 to 4.14.245
#########
Bugfixes:
#########
- The firmware partition lookup in gluon-web-admin's firmware update
page was using an old partition label and therefore failed to look up
the available flash size. This resulted in misleading error messages in
case the uploaded firmware file exceeds the flash size.
- Android 9 and higher do not properly wake up to renew their MLD
subscriptions, therefore dropping out of the Neighbor Discovery MLD
group, which leads to broken IPv6 connectivity after the device has
slept for a while. A workaround has been deployed to wake these devices
up in regular intervals to prevent this regression.
- Missing bandwith limit settings resulted in a respondd crash for v2021.1.
- The Tunneldigger VPN provider was not registered with the Gluon VPN 
backend, resulting in broken Tunneldigger configurations.
- Disabling Radio interfaces in v2021.1 could lead to nullpointer 
dereferences in the respondd airtime module, as the survey returns no 
data in this case.
#########
Internal:
#########
Mesh-VPN Abstraction Layer:
In preparation for the introduction of new tunneling protocols, the
gluon-mesh-vpn framework has been modularized. This allows for providers
to use a standard interface and keep their implementation details in a
dedicated package.
#######################
Continuous Integration:
#######################
* GitHub Actions
   - GitHub actions is now enabled for the Gluon project, build-testing
all available targets.
   - CI jobs are now run based on which paths have been modified.
   - Linters for lua and shell scripts have been integrated.

Folgende Comunnity spezifischen Änderungen gab es im siteconf repo:
* Das Buildscript kann nun builddir cleanups über alle Architekturen.
* ein RC autoupdater branch ist eingerichtet um das testen von release
canidates zu vereinfachen.
* Alle Domains bekommen ein zusätzliches neues IPv6 Präfix.
* Die Domain Delmenhorst wurde westlicher von Delmenhost verschoben und
heißt jetzt Landkreis Oldenburg. Hinzugekommen ist die Domain Bremen.
* Teile der Domain landkreis_osnabrueck wurden in die Domain bad_iburg
verschoben um Domain grenzen weniger durch Ortschaften laufen zu lassen
und die Anzahl der Router pro Domain anzugleichen.
* Die Domain landkreis_wittmund wurde in landkreis_wittmund_nord und
landkreis_wittmund_sued geteilt.
* Der Patch
0004-patches-openwrt-add-0016-ath9k-check-for-deaf-rx-pat.patch wurde
entfernt.
* eine Outdoor channel liste wurde hinzugefügt.
