Mir 0.8 Works On Less ABI Breakage, Touchspots, Responsiveness
Written by Michael Larabel in Ubuntu on 1 October 2014 at 09:49 AM EDT. 16 Comments
While Ubuntu 14.10 on the desktop isn't using Mir by default, Mir 0.8.0 is being prepared for release by Canonical and it has a number of interesting changes.

Among the Mir 0.8 display server highlights are:

- Support for touchspots to visually show touch locations on the screen, albeit at the cost of performance.

- Mir clients can now expose performance information like frame rates and render times via setting the MIR_CLIENT_PERF_REPORT=log environment variable to dump the performance information to the standard output.

- Less sensitivity to ABI breaks by hiding headers from being exposed that have been unused by external projects, etc. There's also more scripts now to detect ABI breakage.

- More improvements to touch responsiveness -- including less lag and smoother scrolling.

- Hardware overlays are now enabled by default.

- A large number of bug-fixes.

More details can be found via the Mir Bazaar repository.
