v0.9.0
This release of flannel brings some significant improvements to the vxlan backend.
- No longer listen for netlink messages. This improves flannel performance at high scale (especially on heavily loaded systems) and minimizes the possibility for dropped traffic when the flannel deamon is stopped (e.g. during upgrades).
- Fully compatible with previous versions of flannel to allow for easy upgrade
- Adds support for new "direct routing" mode where packets are only VXLAN encapsulated if there isn't a directly connected route to the destination host.
It also adds a retry mechanism to the --ip-masq
feature to ensure that iptables
rules are correct.
There are a number of other important bug fixes and improvements. See the complete list below.

v0.7.1
This is primarily a bug fix release which has the following key fixes and improvements.
Kube Subnet Manager
This release introduces a new experimental feature. The Kubernetes API server can now be used as a datastore instead of etcd. This makes deployment easier as flannel no longer directly relies on the presence of an etcd server. To use it, pass the -kube-subnet-mgr
option to the flannel daemon.
This release also contains a large number of merged PRs (thanks everyone for all your contributions, please keep them coming) and some other build, documentation and other minor improvements.
Key PRs merged
kubernetes API server as datastore
#483 add a subnet manager backed by the kubernetes apiserver
#564 Improve kube subnet lease handling
#518 Fix the kube-flannel.yaml in order to work
AWS backend
#540 AWS VPC backend fixes and cleanups
#523 aws-vpc: Fix crash when route has vpc-endpoints
#524 aws-vpc: remove "blackholes"
#507 Update aws-vpc-backend.md
Key Bug fixes
#522 Fixed #521: flanneld hang on at initialEvtsBatch := <-evts because of…
#495 The docker daemon syntax change addressed
#576: backend/vxlan: Set the netmask of the IP used for the vxlan device
Logging
#565 network manager: Improve logging
#555 vxlan logging verbosity
#574: backend/vxlan: Improve the comments and logging
Testing
#490 Add functional (end-to-end) testing
#503 Run e2e tests on travis
Fix logging issue
This is a small point release that fixes a logging issue.
For a complete list of changes v0.6.1...v0.6.2
Now with more pthread
This is a small point release that adds the pthread library to the busybox-based deploy images.
For a complete list of changes v0.6.0...v0.6.1
Bug fix and refactoring release
This is the first release in a while so it's rolling up a large number of small improvements and bug fixes.
- small docs changes
- overhaul of the build system
- experimental support for arm and PPC. The images on quay.io are tagged with the version and architecture. This may change in future so the architecture becomes part of the image name.
- image tags have a
v
prefix so they match the reported version and git tag name.
- improvements to stability and UX tweaks
- refactoring mainly driven by reservation support
- some new features
For a complete list of changes v0.5.5...v0.6.0
NOTE: The deploy images for this version are broken - use version 0.6.1 instead
