Added mir_prompt_session_new_fds_for_prompt_providers_sync API. . mirout: Added load and save options for keeping display configs on disk. . mirout: Added "--" support for applying configuration changes under Unity8. . Fixed failure of DRM hardware cursor {hide(); show(image);} . Added server option: "--cursor software" (MIR_SERVER_CURSOR=software) . Added letterboxing/black bars support to the GL renderer in preparation for generic output cloning. . Added client API for getting the logical size of an output. . Migrated MirCookie to use SHA-256. . Ensure RealKMSOutputConfiguration stays in sync with actual hardware state. . Added support for drag-and-drop. . Lots of other client API enhancements. . Minor clean-ups, optimizations and dead code removal. . Added support for building on Ubuntu 17.10 artful. . Update example code to use undeprecated API. . mesa-kms: Support hardware cursors in hybrid setups. . Rework and publish the graphics platform APIs - Bugs fixed: .
