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.
* Configuration loss on upgrade under certain circumstances
(`#1496 <https://github.com/freifunk-gluon/gluon/issues/1496>`_)
The issue can only occur when upgrading from 2018.1 and there are multiple
mirror entries in *site.conf* (specifically, an early failure for one of the
mirrors, e.g. during DNS resolution, followed by a successful upgrade from a
different mirror triggers the issue).
This is a regression in Gluon 2018.1.
* Next-node ARP issue
(`#1488 <https://github.com/freifunk-gluon/gluon/issues/1488>`_)
A routing table issue leads to ARP requests being sent from the next-node IPv4 address, but with
a node-specific source MAC address. This can make the next-node IPv4 address unreachable.
This is a regression in Gluon 2018.1.
