*** RELEASE 2.0.0, 7 APRIL 2010 ***

CORE
 - Add Stopwatch ability to pull CPU time or Calendar time.
 - Add name() method to VW exceptions to stringify the exception type.
 - Add general.tmp_directory config file key.
 - Fix mutex lock inside Condition::timed_wait().
 - Add concurrent-safe queue class (ThreadQueue).
 - Remove TerminationHandler, it was really fragile.
 - Change Warning/ErrorMessage behavior; they prepend "Warning: " or "Error: "
 - Change ProgressBars to use a *.progress log namespace.
 - Change ProgressBars to enforce 80-char width.
 - Change values of ErrorMessage and InfoMessage, swapping them back to the
   beta1 way.
 - Change vwrc log filters to support limited wildcarding.

MATH
 - Extend AffineFittingFunctor, SimilarityFittingFunctor,
   TranslationRotationFittingFunctor, and TranslationFittingFunctor to work in
   N-dimensions.
 - Add Homogeneous error metric.
 - Add CDFAccumulator.
 - Rename SparseSkylineMatrix to MatrixSparseSkyline.
 - Change MatrixSparseSkyline to inherit from MatrixBase.
 - Add VectorReorganize and MatrixReorganize to re-map indices.
 - Add Cuthill McKee ordering algorithm for MatrixSparseSkyline.
 - Add Fundamental Matrix solvers.
 - Rename Null to Nullspace.
 - Add Rank and Nullity matrix operations.
 - Fix excessive logging inside LevenbergMarquardt; improves speed.
 - Add function to convert XYZ Euler angles to quaternions.

IMAGE
 - Fix rounding bug with premultipliying (bugfix from William Rucklidge)
 - Add alpha_to_mask() function.
 - Fix PixelWithAlpha to properly noop if input already has an alpha channel.

FILEIO
 - Add DiskCacheImageView constructor parameter to choose the cache directory.
 - Change DiskImageResourceGDAL to turn on LZW compression by default for
   TIFFs.
 - Remove obsolete/broken JP2.h code.
 - Add DiskImageResourceGDAL::set_gdal_cache_size to set GDAL's internal cache
   size.

CAMERA
 - Fix incorrect rotation inside AdjustCameraModel.
 - Add PinholeModel method to set camera projection matrix.
 - Add CameraMatrix fitting functor that attempts to solve for camera
   projection matrix.

BUNDLE ADJUSTMENT
 - Move Bundle Adjustment code from Camera into its own module.
 - Add timers for internal functions; see loglevel DebugMessage namespace "ba".
 - Add RobustSparseKGCP, a robust BA that doesn't deweight Ground Control
   Points.
 - Add Camera Relation Network, a new perspective of Control Network. Allows
   for a Camera major organization.
 - Add efficient ControlNetworkLoader.
 - Refactor Sparse Bundle Adjustment to reduce speed by half and to build
   sparse matrix more efficiently.

CARTOGRAPHY
 - Fix CameraBBox to work with meters per pixel on projection plane.
 - Add D_MOON and D_MARS datums as well known datums.

MOSAIC
 - Add Gigapan viewer support inside image2qtree.

STEREO
 - Change EM subpixel to switch between Newton method and Gauss-Newton for
   speed improvements.
 - Add valid_pad technique that minimizes the cuts into the disparity that
   happen from the pyramid correlator.
 - Add Disparity Transform; it transforms an image by using a Disparity Map.

INTEREST POINT
 - Add Scaled Gradient Descriptor, a new custom and fast descriptor.
 - Add OBALoG detector code with help from KSU.
 - Add BoxFilterView which allows for arbitrary box filter application.
 - Add IntegralDescriptor type for descriptors that use Integral Images.
 - Add Scaled Gradient Descriptor 2, which is a simple descriptor that uses
   Integral Images for calculation.

TOOLS
 - ipfind: culling fix for threaded detection.
 - ipfind: add gain setting as  standard interface to all algorithms'
           thresholds.
 - correlate: modify to mimic Ames Stereo Pipeline's stereo.
 - colormap: Fix nodata value detection.
 - grassfirealpha: new tool that provides a grassfire image in the alpha
   channel.
 - all: accept -h as an alternative to --help.

BUILD
 - Add dependency on Boost Graph library.
 - Switch a large number of tests to use Google Test.
 - Enable silent build (use --disable-silent-rules or make V=1 to revert).
 - Disable static libraries by default (use --enable-static to revert)
 - Rework Boost detection. Again. Ad infinitum?
 - Add support for autoconf 2.65.
 - Fix support for really old autoconf.
 - Fix TIFF-inside-GDAL detection.
 - Add support for enabling Google perftools' tcmalloc and libprofiler.
 - Many FreeBSD fixes. VW should compile on FreeBSD now thanks to Steve Wills!

MISC
 - Add experimental GDB 7.0+ python-based pretty printers for select VW types.
 - Compiler warning fixes throughout the tree.
 - Some functions that the comments marked as deprecated will also throw
   compiler warnings now if you use them.
