Il server grafico Mir, sviluppato da Canonical, si aggiorna alla version 0.16, con dei bei grossi cambiamenti. Cambiamenti da tenere d'occhio soprattutto dai gamer dato l'imminente arrivo di DirectX11 su Linux.
Novità?
Mir 0.16.0 porta un buffer di detenzione tempo molto più breve per comporre il sistema, in maniera da fornire framerate più elevati e più lisci, progressi su una nuova semantica del buffer, cambiamenti su Mir-on-X11, l'inizio di refactoring del codice per supportare i diversi renderer OpenGL (come Vulkan in futuro), e un'altra bella sfilza di modifiche.
Ecco il changelog completo in inglese:
