- Add link to experimental features - New 1.13 cancellable operations should now be properly handled by the Docker for desktop - `daemon.json` should render nicely in the UI - Allow to reset faulty `daemon.json` through a link in advanced subpanel ### Docker for Mac 1.13.0, 2017-01-19s **Upgrades** - [Docker 1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0) - [Docker Compose 1.10](https://github.com/docker/compose/releases/tag/1.10.0) - [Docker Machine 0.9.0](https://github.com/docker/machine/releases/tag/v0.9.0) - [Notary 0.4.3](https://github.com/docker/notary/releases/tag/v0.4.3) - Linux kernel 4.9.4 - qcow-tool 0.7.2 **New** - The storage location of the Linux volume can now be moved - Reclaim disk size on reboot - You can now edit filesharing paths - Memory can be allocated with 256 MiB steps - Proxy can now be completely disabled - Support for arm, aarch64, ppc64le architectures using qemu - Dedicated preference pane for advanced configuration of the docker daemon (edit `daemon.json`) - Docker Experimental mode can be toggled - Better support for Split DNS VPN configurations - Use more DNS servers, respect order **Bug fixes and minor changes** - You cannot edit settings while docker is restarting - Support Copy/Paste in About box - Auto update polling every 24h - Kernel boots with vsyscall=emulate arg and CONFIG_LEGACY_VSYSCALL is set to NONE in Moby - Fixed vsock deadlock under heavy write load - If you opt-out of analytics, you're prompted for approval before a bug report is sent - Fixed bug where search domain could be read as `DomainName` - Dedicated preference pane for HTTP proxy settings - Dedicated preference pane for CPU & Memory computing resources - Privacy settings moved to the general preference pane - Fixed an issue where the preference pane disappeared when the welcome whale menu was closed - HyperKit: code cleanup and minor fixes - Improvements to Logging and Diagnostics - osxfs: switch to libev/kqueue to improve latency - VPNKit: improvements to DNS handling - VPNKit: Improved diagnostics - VPNKit: Forwarded UDP datagrams should have correct source port numbers - VPNKit: add a local cache of DNS responses - VPNKit: If one request fails, allow other concurrent requests to succeed. For example this allows IPv4 servers to work even if IPv6 is broken. - VPNKit: Fix bug that could cause the connection tracking to underestimate the number of active connections ## Stable Releases of 2016 ### Docker for Mac 1.12.5, 2016-12-20s **Upgrades** - Docker 1.12.5 - Docker Compose 1.9.0 ### Skipped Docker for Mac 1.12.4 We did not distribute a 1.12.4 stable release ### Docker for Mac 1.12.3, 2016-11-09s **Upgrades** - Docker 1.12.3 - Linux Kernel 4.4.27 - Notary 0.4.2 - Docker Machine 0.8.2 - Docker Compose 1.8.1 - Kernel vsock driver v7 - aufs 20160912 **Bug fixes and minor changes** **General** - Fixed an issue where the whale animation during setting change was inconsistent - Fixed an issue where some windows stayed hidden behind another app - Fixed an issue where the Docker status would continue to be yellow/animated after the VM had started correctly - Fixed an issue where Docker for Mac was incorrectly reported as updated - Channel is now displayed in About box - Crash reports are sent over Bugsnag rather than HockeyApp - Fixed an issue where some windows did not claim focus correctly - Added UI when switching channel to prevent user losing containers and settings - Check disk capacity before Toolbox import - Import certificates in `etc/ssl/certs/ca-certificates.crt` - disk: make the "flush" behaviour configurable for database-like workloads. This works around a performance regression in 1.12.1. **Networking**

This section details Docker Desktop for Mac releases from late 2016 to early 2017, covering versions 1.12.3, 1.12.5 and 1.13.0. Upgrades include Docker, Docker Compose, Docker Machine, Notary, and Linux kernel. Key features added in 1.13.0 are the ability to move the Linux volume storage location, reclaim disk space on reboot, edit filesharing paths, allocate memory in 256 MiB steps, disable the proxy, and support additional architectures (arm, aarch64, ppc64le). It also includes a preference pane for `daemon.json` configuration, Docker experimental mode toggle, and Split DNS VPN support. Bug fixes address UI inconsistencies, window focus issues, status reporting, update notifications, certificate importing, and vsock deadlocks. Networking improvements include better DNS handling and resolution via VPNKit, including a DNS response cache. osxfs performance is improved via libev/kqueue. Stability is improved through various HyperKit and VPNKit fixes.
