Mir 0.20 Ships With Screencasting To Virtual Output Support

Canonical developers have put out version 0.20 of Mir in time for the next OTA update for Ubuntu Phones.

As outlined via the change-log in the Mir Bazaar repository, 0.20 is quite a fine update. First up, Mir 0.20 brings support to allow screencasting to create a virtual output, which is needed for Ubuntu to support Miracast on Mir. Miracast remains the dominant protocol for connecting external monitors/TVs over WiFi. Android has supported this since the 4.x days and there's been various Linux desktop efforts like MiracleCast while it's great to see see Canonical/Ubuntu making more progress with their Miracast support for Ubuntu Phone/Tablet devices.

Mir 0.20 also has logging improvements, example improvements, various bug fixes, an option to use the Gold linker at build time, and many bug fixes. There's also a Mir bug that caused Ubuntu Phone not to be usable when a call comes in, which is now fixed with v0.20.
