* `osxfs`:
  - Fixed sporadic EBADF errors and End_of_file crashes due to a race corrupting node table invariants
  - Fixed a crash after accessing a sibling of a file moved to another directory caused by a node table invariant violation
* Fixed issue where Proxy settings were applied on network change, causing docker daemon to restart too often
* Fixed issue where log file sizes doubled on docker daemon restart

### Beta 13 Release Notes (2016-05-25 1.11.1-beta13)

**New**

* `osxfs`: Enabled 10ms dcache for 3x speedup on a `go list ./...` test against docker/machine. Workloads heavy in file system path resolution (common among dynamic languages and build systems) will have those resolutions performed in amortized constant time rather than time linear in the depth of the path so speedups of 2-10x will be common.

* Support multiple users on the same machine, non-admin users can use the app as long as `vmnetd` has been installed. Currently, only one user can be logged in at the same time.

* Basic support for using system HTTP/HTTPS proxy in docker daemon

**Known issues**

* Docker.app sometimes uses 200% CPU after macOS wakes up from sleep mode. The issue is being investigated. The workaround is to restart Docker.app.

**Bug fixes and minor changes**

* `osxfs`:
  - setting `atime` and `mtime` of nodes is now supported
  - Fixed major regression in Beta 12 with ENOENT, ENOTEMPY, and other spurious errors after a directory rename. This manifested as `npm install` failure and other directory traversal issues.
  - Fixed temporary file ENOENT errors
  - Fixed in-place editing file truncation error, such as when running `perl -i`
* improved time synchronisation after sleep

### Beta 12 Release (2016-05-17 1.11.1-beta12)

**Upgrades**

* FUSE 7.23 for osxfs

**Known issues**

* Docker.app sometimes uses 200% CPU after macOS wakes up from sleep mode. The issue is being investigated. The workaround is to restart Docker.app.

**Bug fixes and minor changes**

* UI improvements
* Fixed a problem in osxfs where`mkdir` returned EBUSY but directory was created.

### Beta 11 Release (2016-05-10 1.11.1-beta11)

* Linux kernel 4.4.9

**Bug fixes and minor changes**

* Desktop notifications after successful update
* No "update available" popup during install process
* Fixed repeated bind of privileged ports
* `osxfs`: Fixed the block count reported by stat
* Moby (Backend) fixes:
  - Fixed `vsock` half closed issue
  - Added NFS support
  - Hostname is now Moby, not Docker
  - Fixes to disk formatting scripts
  - Linux kernel upgrade to 4.4.9

### Beta 10 Release (2016-05-03 1.11.0-beta10)

**New**

* Token validation is now done over an actual SSL tunnel (HTTPS). (This should fix issues with antivirus applications.)

**Bug fixes and minor changes**

* UCP now starts again
* Include debugging symbols in HyperKit
* vsock stability improvements
* Addressed glitches in **Preferences** panel

### Beta 9 Release (2016-04-26 1.11.0-beta9)

**New**

* New Preferences window - memory and vCPUs now adjustable
* `localhost` is now used for port forwarding by default.`docker.local` will no longer work as of Beta 9.

**Known issues**

* Docker.app sometimes uses 200% CPU after macOS wakes up from sleep mode. The issue is being investigated. The workaround is to restart Docker.app.

**Bug fixes and minor changes**

* Fix loopback device naming
* Improved docker socket download and osxfs sequential write by 20%
* `com.docker.osxfs`
  - improved sequential read throughput by up to 20%
  - improved `readdir` performance by up to 6x
  - log all fatal exceptions
