versioning scheme to reflect this. Two channels are available: monthly and quarterly. 237Any given monthly release will only receive security and bugfixes until the next monthly 238release is available. Quarterly releases receive security and bugfixes for 4 months after 239initial release. This release includes bugfixes for 1.13.1 but 240there are no major feature additions and the API version stays the same. 241Upgrading from Docker 1.13.1 to 17.03.0 is expected to be simple and low-risk. 242 243### Client 244 245* Fix panic in `docker stats --format` [#30776](https://github.com/docker/docker/pull/30776) 246 247### Contrib 248 249* Update various `bash` and `zsh` completion scripts [#30823](https://github.com/docker/docker/pull/30823), [#30945](https://github.com/docker/docker/pull/30945) and more... 250* Block obsolete socket families in default seccomp profile - mitigates unpatched kernels' CVE-2017-6074 [#29076](https://github.com/docker/docker/pull/29076) 251 252### Networking 253 254* Fix bug on overlay encryption keys rotation in cross-datacenter swarm [#30727](https://github.com/docker/docker/pull/30727) 255* Fix side effect panic in overlay encryption and network control plane communication failure ("No installed keys could decrypt the message") on frequent swarm leader re-election [#25608](https://github.com/docker/docker/pull/25608) 256* Several fixes around system responsiveness and datapath programming when using overlay network with external kv-store [docker/libnetwork#1639](https://github.com/docker/libnetwork/pull/1639), [docker/libnetwork#1632](https://github.com/docker/libnetwork/pull/1632) and more... 257* Discard incoming plain vxlan packets for encrypted overlay network [#31170](https://github.com/docker/docker/pull/31170) 258* Release the network attachment on allocation failure [#31073](https://github.com/docker/docker/pull/31073) 259* Fix port allocation when multiple published ports map to the same target port [docker/swarmkit#1835](https://github.com/docker/swarmkit/pull/1835) 260 261### Runtime 262 263* Fix a deadlock in docker logs [#30223](https://github.com/docker/docker/pull/30223) 264* Fix cpu spin waiting for log write events [#31070](https://github.com/docker/docker/pull/31070) 265* Fix a possible crash when using journald [#31231](https://github.com/docker/docker/pull/31231) [#31263](https://github.com/docker/docker/pull/31263) 266* Fix a panic on close of nil channel [#31274](https://github.com/docker/docker/pull/31274) 267* Fix duplicate mount point for `--volumes-from` in `docker run` [#29563](https://github.com/docker/docker/pull/29563) 268* Fix `--cache-from` does not cache last step [#31189](https://github.com/docker/docker/pull/31189) 269 270### Swarm Mode 271 272* Shutdown leaks an error when the container was never started [#31279](https://github.com/docker/docker/pull/31279) 273* Fix possibility of tasks getting stuck in the "NEW" state during a leader failover [docker/swarmkit#1938](https://github.com/docker/swarmkit/pull/1938) 274* Fix extraneous task creations for global services that led to confusing replica counts in `docker service ls` [docker/swarmkit#1957](https://github.com/docker/swarmkit/pull/1957) 275* Fix problem that made rolling updates slow when `task-history-limit` was set to 1 [docker/swarmkit#1948](https://github.com/docker/swarmkit/pull/1948) 276* Restart tasks elsewhere, if appropriate, when they are shut down as a result of nodes no longer satisfying constraints [docker/swarmkit#1958](https://github.com/docker/swarmkit/pull/1958) 277* (experimental) 278 279## 1.13.1 (2017-02-08) 280 281**IMPORTANT**: On Linux distributions where `devicemapper` was the default storage driver, 282the `overlay2`, or `overlay` is now used by default (if the kernel supports it). 283To use devicemapper, you can manually configure the storage driver to use through 284the `--storage-driver` daemon option, or by setting "storage-driver" in the `daemon.json` 285configuration file. 286 287**IMPORTANT**: In Docker 1.13, the managed plugin api changed, as compared to the experimental 288version introduced in Docker 1.12.

This makes Docker more stable and less likely to crash and reduces the memory footprint of many common operations 2535* All packaging operations are now built on the Go language’s standard tar implementation, which is bundled with Docker itself. This makes packaging more portable across host distributions, and solves several issues caused by quirks and incompatibilities between different distributions of tar 2536* Docker can now create, remove and modify larger numbers of containers and images graciously thanks to more aggressive releasing of system resources. For example the storage driver API now allows Docker to do reference counting on mounts created by the drivers 2537With the ongoing changes to the networking and execution subsystems of docker testing these areas have been a focus of the refactoring. By moving these subsystems into separate packages we can test, analyze, and monitor coverage and quality of these packages 2538* Many components have been separated into smaller sub-packages, each with a dedicated test suite.
