Release notes
2018.1.0b12 Release Notes (diff since 2018.1.0b11)
System Requirements Changes

    Removed support for Windows XP in standalone player builds. Windows Vista is the now minimum supported OS for Windows standalone player.
    Deprecated support for MonoDevelop. VisualStudio is now the recommended and supported C# editor on both macOS and Windows.

Known Issues in 2018.1.0b12

    GI: Editor crashes after assigning Light Probe Group to Anchor Override Parameter. (1002580)

    GI: Progressive Lightmapper doesn't work on Linux, which means that all 3D templates will crash on launch. The 2D template is not affected however. (913799)
