Note 2.6.4 was created to relax the iptables blocking rule added in this release, because it turned out to be too strict.
Release 2.6.3
This release has a couple of security improvements, and some other fixes.
Note that we still recommend to remove CAP_NET_RAW access from untrusted containers.
Block non-local traffic to the Weave control port [CVE-2020-8558] #3805
Tell Linux not to accept router advisory messages [CVE-2020-11091] #3801
Network Policy Controller: add a metric to show errors while operating #3804
Network Policy Controller: don't treat named port as a fatal error #3790
Weave 2.6.2
Release 2.6.2
fixes a regression found in 2.6.1 release and fix to prevent CPU spinning
Bug fixes
Weave Net can not be used in fastdp mode and always falls back to sleeve mode #3781, #3783
Restrict timeout value passed to pcap library to a value less than 2^31 microseconds to
prevent CPU spinning in sleeve mode #3782
Weave 2.6.1
Note a regression was reported #3781 - we advise waiting for resolution before upgrading
Release 2.6.1
support for iptables 1.8 and a bug-fix
Bug fixes
removes a possible deadlock which could cause Weave Net on node restart to stop connecting to peers and stops responding to API requests #3762#3763
Other improvements
Weave Net Kubernetes images by default uses iptables 1.8 with legacy (netfilter) backend with
option to choose nftables as iptables backend #3465, #3747
Weave Net 2.6.0
Release 2.6.0
This release reduces CPU and memory usage in larger clusters, by sending notifications to a smaller set of peers and coalescing updates to reduce topology recalculation. #3715, #3732
The default soft limit on connections has been raised from 100 to 200.
This release improves resiliency in a number of areas,
and extends the Prometheus metrics exported by Weave Net.
Change in behaviour: on Kubernetes, the client source IP is preserved
when calling from a pod to a service.
This feature, introduced in version 2.4.0 and previously turned on by
setting NO_MASQ_LOCAL=1 is now on by default. #3389, #3756
Features
Reload router iptables rules if they get cleared, e.g. when firewalld restarts. #3802
(weave-npc rules are not reloaded)
Add new type and encryption labels to weave_connections metric #3788, #3789
Weave Net now exports Go metrics for heap size, garbage collection, etc. #3838
Register container name and its network aliases with weaveDNS #3084, #3090
