**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/

+ Updated docker events to include more meta-data and event types [#18888](https://github.com/docker/docker/pull/18888)

This change is backward compatible in the API, but not on the CLI.

+ Add `--blkio-weight-device` flag to `docker run` [#13959](https://github.com/docker/docker/pull/13959)

- Fix the `--quiet` flag on `docker build` to actually be quiet [#17428](https://github.com/docker/docker/pull/17428)

- Fix `docker images --filter dangling=false` to now show all non-dangling images [#19326](https://github.com/docker/docker/pull/19326)

- Forbid `exec` during container restart [#19722](https://github.com/docker/docker/pull/19722)

- devicemapper: Increasing `--storage-opt dm.basesize` will now increase the base device size on daemon restart [#19123](https://github.com/docker/docker/pull/19123)

+ Add `--userns-remap` flag to `daemon` to support user namespaces (previously in experimental) [#19187](https://github.com/docker/docker/pull/19187)

+ Docker Content Trust now supports the ability to read and write user delegations [#18887](https://github.com/docker/docker/pull/18887)

This is an optional, opt-in feature that requires the explicit use of the Notary command-line utility in order to be enabled.

Enabling delegation support in a specific repository will break the ability of Docker 1.9 and 1.8 to pull from that repository, if content trust is enabled.

* Allow SELinux to run in a container when using the BTRFS storage driver [#16452](https://github.com/docker/docker/pull/16452)

* Use content-addressable storage for images and layers [#17924](https://github.com/docker/docker/pull/17924)

Note that a migration is performed the first time docker is run; it can take a significant amount of time depending on the number of images and containers present.

Images no longer depend on the parent chain but contain a list of layer references.

`docker load`/`docker save` tarballs now also contain content-addressable image configurations.
