Moby v1.10.0 Release Notes

Release Date: 2016-02-04 // about 8 years ago

  • IMPORTANT: Docker 1.10 uses a new content-addressable storage for images and layers. 🐳 A migration is performed the first time docker is run, and can take a significant amount of time depending on the number of images present. 🐳 Refer to this page on the wiki for more information: https://github.com/docker/docker/wiki/Engine-v1.10.0-content-addressability-migration 🚀 We also released a cool migration utility that enables you to perform the migration before updating to reduce downtime. 🐳 Engine 1.10 migrator can be found on Docker Hub: https://hub.docker.com/r/docker/v1.10-migrator/
