Project is pleased to announce the release 4.12 Beta 2
of CGAL, the Computational Geometry Algorithms Library.

CGAL version 4.12 Beta 2 is a public testing release. It should provide
a solid ground to report bugs that need to be tackled before the
release of the final version of CGAL 4.12 in April.

WARNING: This release features an important change of the CMake scripts
used to configure the CGAL libraries and examples. Developers using
makefiles or the Ninja build-system should set the CMAKE_BUILD_TYPE to
Release manually, to avoid using CGAL libraries without any compile-time
optimization. Please read the first paragraph of the release notes
carefully.

Note that, since the release CGAL-4.12 Beta 1, the header-only mode of CGAL
has been modified, and documented.

Besides fixes and general enhancement to existing packages, the following
has changed since CGAL 4.11:

Using CGAL Header-only

• It is now possible to use CGAL without configuring it with CMake, as a
  header-only library. Note that, even if CGAL is header-only, its
  dependencies (such as GMP and MPFR) are not all header-only.

2D Movable Separability of Sets (new package)

• A new package called "2D Movable Separability of Sets" has been
  introduced. It handles a class of problems that deal with moving
  sets of objects in the plane; the challenge is to avoid collisions
  between the objects while considering different kinds of motions and
  various definitions of separation.

  At this point this package consists of the implementations of
  various predicates and constructions related to castings of
  polygonal objects. In particular, it can be used to determine
  whether a feasible mold for a polygonal object does exist. If a mold
  exists, the package can also be used to compute all possible
  orientations of the feasible molds and the corresponding motions
  needed to remove the casted object from the mold.

Classification (new package)

• This package offers an algorithm that classifies a data set into a
  user-defined set of labels (such as ground, vegetation, buildings,
  etc.). A flexible API is provided so that users can classify any
  type of data, compute their own local features on the input data
  set, and define their own labels.

Kinetic Data Structures (removed package)

• This package has been removed from CGAL-4.12. Users of the package
  will have to keep using the source code available in CGAL-4.11 or
  earlier.

changes.
