slic3er 1.1.6 stable is out..

New features:

    New algorithm for single-width thin walls, now faster and more accurate
    New algorithm for linear gap fill: no more shaking and adaptive extrusion width!
    New option for turning autocentering off in the plater
    Ability to set per-object and per-region settings
    New object editor window for composing multi-part objects (no need to use AMF files anymore)
    Support for modifier meshes to apply distinct local settings by intersecting them with the main model
    Import/export entire configuration bundles
    Per-region settings are now written to AMF files and read back in (they could be even assigned from a CAD)
    New option for generating internal interface shells between multi-part objects (useful for translucent objects or manually-designed support material)
    New pillars support material for saving time and material and easier removal

Improvements:

    Huge internal refactoring for better modularity and less memory usage
    More detailed thumbnails in plater
    Prevent user from saving a preset named "- default -" which could lead to confusion
    Real-time validation for most config options

Changes:

    The Spiral Vase option is now more strict because it will require user to set other options in a compatible way for it to work. This might change again in the future.
    The Fill Density option is now expressed as a percentage and uses a combobox

New features:

    Ability to cut models in two with a slicing plane (resulting parts can be also exported)
    Support material is automatically excluded below successful bridges and only added where strictly needed in order to make anchors for potential bridges; this results in much lighter support material for parts having flat overhanging areas

Improvements:

    Support material distance from object was reduced and made more consistent
    A base flange is added below pillars support material in order to connect them on the build plate
    Spiral vase mode is prevented automatically for multi-island layers (#1938)

Bug fixes:

    Fixed an upstream bug in the Clipper library causing some random perimeter segments to be swapped in order (#1834)
    Bridge detection was choosing bad orientation in some cases
    Sometimes islands were not completed fully before moving onto the next one (#1137)
    Gap fill was not inserted in the corrected order before leaving an island (#1907)
    A regression caused the Default Extrusion Width option to be ignored (#1958)
    The [timestamp] placeholder in filename was not updated at every single job (#1957 #1995)
    A regression caused bad loading of multi-extruder values in GUI (#1984)
    Fixed regression and ambiguity about multi-value placeholders like [first_layer_temperature_1] (#1899)
    Fixed regression causing random lack of hole perimeters on Windows (#1950)
    Fixed random crash when closing the Object Settings window

This is an experimental release. Help us testing!

Improvements:

    Holes in object footprint are now ignored when generating raft to make it more continuous

Changes:

    Retract on layer change is automatically disabled with Spiral vase is enabled
    The command line --save option will now only save the options that were explicitely specified on command line, without the implicit defaults

Bug fixes:

    Fixed a bug in an upstream library causing crashes or missing perimeter segments in rare situations (#2028)
    Fixed a crash when skirt was contained in brim area (#2058)
    Fixed a regress causing bridge flow to be incorrect when a default extrusion width was specified (#2027)
    M73 was exceeding 100% when multiple objects were printed together (only for Makerware/Sailfish) (#1912)
