CHANGELOG.txt

nanoflann 1.3.0: Released Aug 28, 2018
  * Instructions for `make install` for Linux and Windows (Closes #87).
  * Fix all (?) MSVC conversion warnings (Closes: #95).
  * Avoid need for _USE_MATH_DEFINES in MSVC (Closes: #96)
  * Eigen::Matrix datasets: now uses std::cref() to store a reference to matrix.
  * GSOC2017 contributions by Pranjal Kumar Rai:
    * Support for dynamic datasets.
    * Support for non-Euclidean spaces: SO(2), SO(3)

nanoflann 1.2.3: Released Dec 20, 2016
  * Fixed: split plane now correctly chooses the dimensions with the largest span.
    Should lead to more optimal trees.

nanoflann 1.2.2: Released Nov 10, 2016
  * knnSearch() now also returns the number of valid points found.

nanoflann 1.2.1: Released Jun 1, 2016
  * Fix potential compiler warnings if `IndexType` is signed.
  * New unit tests comparing the results to those of brute force search.

nanoflann 1.2.0: Released May 5, 2016
  * Fixed: many classes constructors get const ref arguments but stored const values.

nanoflann 1.1.9: Released Oct 2, 2015
  * Added KDTreeSingleIndexAdaptor::radiusSearchCustomCallback() (Based on a suggestion by Yannick Morin-Rivest)
  * Better documentation in class headers.
  * Cleanup of unused code.
  * Parameter KDTreeSingleIndexAdaptorParams::dim has been removed since it was redundant.

nanoflann 1.1.8: Released May 2, 2014
  * Created hidden constructors in nanoflann class, to disallow unintentional copies which will corrupt
    the internal pointers.
  * Fixed crash if trying to build an index of an empty dataset.

nanoflann 1.1.7: Released Aug 24, 2013
  * Two internal containers are now automatically defined as fixed-size arrays if the
    problem dimension is known at compile time, improving efficiency.
    The new/modified datatypes are: KDTreeSingleIndexAdaptor::BoundingBox, KDTreeSingleIndexAdaptor::distance_vector_t
  * Fixed compilation with GCC 4.8 and C++11 enabled (Thanks to Simon Praetorius).

nanoflann 1.1.6: Released May 14, 2013
  * Fixed warnings about unused parameters.
  * Fixed L1_adaptor.accum_dist(), which implemented L2 instead (Closes #1)
  * Fixed wrong typedef in KDTreeEigenMatrixAdaptor<> for IndexType!=size_t (Closes: #2)

nanoflann 1.1.5: Released Mar 25, 2013
  * Fixed: Memory pool wasn't freed after each call to buildIndex()
  * GCC: Added -isystem flag to gtest headers to avoid pedantic warnings.

nanoflann 1.1.4: Released Jan 11, 2013
  * Fixed compilation with Visual Studio 11 (MSVC 2012).
  * Fixed compilation of gtest with VS11 and its _VARIADIC_MAX "bug".
  * Added a security check to launch an exception if searches are attempted before buildIndex().
  * New example to demonstrate save/load the index to files.
  * save/load methods exposed as public.

nanoflann 1.1.3: Released Jun 6, 2012
  * GTest sources are now embedded, due to the changes in newer Ubuntu packages which don't carry the precompiled libs.
  * Added asserts to detect whether the user passes NULL as query points.
  * New method RadiusResultSet::worst_item()
  * New method RadiusResultSet::set_radius_and_clear()
  * Avoid potential collision of min/max macros with <windows.h>
  * Removed unneeded #include's of std headers.
  * New sample code for vectors of vectors.
  * Fixed building of tests for MSVC in Windows.
  * Allow manually setting the path to Eigen3 (mainly for building examples under Windows).

nanoflann 1.1.2: Released May 2, 2012
  * Better documentation and added graphs of a benchmarking for helping choosing "leaf_max_size".
  * Now KDTreeSingleIndexAdaptor::buildIndex() can be called several times
     even when the dataset size changes (Thanks to Rob McDonald for reporting!)

nanoflann 1.1.1: Released Feb 1, 2012
  * Some fixes to kd_tree index and L1/L2 metrics to allow distinct types
     in data elements and in the distances. This is mainly to permit elements
	 being vectors of integers (e.g. uint8_t) but distances being real numbers.
  * Examples and unit tests have been corrected to use template arguments
     instead of being hard-wired to "float" data types (Thanks Thomas Vincent
	 for noticing!).

nanoflann 1.1.0: Released Dec 15, 2011
  * Fixed warnings for MSVC and for GCC with "-Wall -pedantic"
  * Updated performance tests to work with the final nanoflann code (they were
     written for a very early version).
  * All main classes now have new template arguments for the type of indice,
     which now defaults to "size_t" instead of "int". In case this breaks
     backward compatibility in user code, especify "int" to override the default
     template arguments, although "size_t" it's recommended.

nanoflann 1.0.0: Released Aug 30, 2011
  * Initial version
