**Bug fixes and minor changes**

* UCP now starts again
* Include debugging symbols in HyperKit
* vsock stability improvements
* Addressed glitches in **Preferences** panel
* Fixed issues impacting the “whale menu”
* Fixed uninstall process
* HyperKit vcpu state machine improvements, may improve suspend/resume


### 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
* More reliable DNS forwarding over UDP and TCP
* UDP ports can be proxied over vsock
* Fixed EADDRINUSE (manifesting as errno 526) when ports are re-used
* Send ICMP when asked to not fragment and we can't guarantee it
* Fixed parsing of UDP datagrams with IP socket options
* Drop abnormally large ethernet frames
* Improved HyperKit logging
* Record virtual machine start and stop events

### Beta 8 Release (2016-04-20 1.11.0-beta8)

**New**

* Networking mode switched to VPN compatible by default, and as part of this change the overall experience has been improved:
 - `docker.local` now works in VPN compatibility mode
 - exposing ports on the Mac is available in both networking modes
 - port forwarding of privileged ports now works in both networking modes
 - traffic to external DNS servers is no longer dropped in VPN mode


* `osxfs` now uses `AF_VSOCK` for transport giving ~1.8x speedup for large sequential read/write workloads but increasing latency by ~1.3x. `osxfs` performance engineering work continues.


**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**

* Apple System Log now used for most logs instead of direct filesystem logging
* `docker_proxy` fixes
* Merged HyperKit upstream patches
* Improved error reporting in `nat` network mode
* `osxfs` `transfused` client now logs over `AF_VSOCK`
* Fixed a `com.docker.osx.HyperKit.linux` supervisor deadlock if processes exit during a controlled shutdown
* Fixed VPN mode malformed DNS query bug preventing some resolutions


### Beta 7 Release (2016-04-12 1.11.0-beta7)

**New**

* Docs are updated per the Beta 7 release
* Use AF_VSOCK for docker socket transport

**Upgrades**

* docker 1.11.0-rc5
* docker-machine 0.7.0-rc3
* docker-compose 1.7.0rc2


**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

* If VPN mode is enabled and then disabled and then re-enabled again, `docker ps` will block for 90s

**Bug fixes and minor changes**

* Logging improvements
* Improve process management

### Beta 6 Release (2016-04-05 1.11.0-beta6)

* docker-machine 0.7.0-rc3
* docker-compose 1.7.0rc2

**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`.

* If VPN mode is enabled, then disabled and re-enabled again,
`docker ps` will block for 90 seconds.

**Bug fixes and minor changes**

* Fixed osxfs multiple same directory bind mounts stopping inotify
* Fixed osxfs `setattr` on mode 0 files (`sed` failures)
* Fixed osxfs blocking all operations during `readdir`
* Fixed osxfs mishandled errors which crashed the file system and VM
