Two channels are available: monthly and quarterly. Any given monthly release will only receive security and bugfixes until the next monthly release is available. Quarterly releases receive security and bugfixes for 4 months after initial release. This release includes bugfixes for 1.13.1 but there are no major feature additions and the API version stays the same. Upgrading from Docker 1.13.1 to 17.03.0 is expected to be simple and low-risk. ### Client * Fix panic in `docker stats --format` [#30776](https://github.com/docker/docker/pull/30776) ### Contrib * 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... * Block obsolete socket families in default seccomp profile - mitigates unpatched kernels' CVE-2017-6074 [#29076](https://github.com/docker/docker/pull/29076) ### Networking * Fix bug on overlay encryption keys rotation in cross-datacenter swarm [#30727](https://github.com/docker/docker/pull/30727)

This chunk of the Docker Engine 17.03 release notes details fixes and updates for runtime (including `docker exec` and Overlay2 issues), Swarm mode (addressing task scheduling and network allocation), and Windows-specific cleanup. It also covers the 17.03.0-ce release, highlighting its monthly release cycle and the lack of major feature additions compared to 1.13.1. Client and networking fixes are noted, along with security mitigations.
