Une MAJ de sécurité est nécessaire sur notre version actuelle. Elle sera effectuée lundi 02/08 entre 12h30 et 13h. L'interruption de service devrait durer quelques minutes (probablement moins de 5 minutes).

===========================================================================
This file contains the main features as well as overviews of specific
bug fixes (and other actions) for each version of ScalFMM since
version 1.1
1.2 ()
-----
- New FMA format to read/write particles
- Add examples repository
- Add distributions generator
- Fix bugs in periodic model
- Fix bug and performance improvements in MPI thread algorithms
- Now we use MPI THREAD SERIALIZED rather than MPI_THREAD_MULTIPLE in MPI+OpenMP algorithm.
- Add Uniform interpolation based on Lagrange polynomials
- Improve tests -> now we use CTest and CDash (Thanks F Rue to Inria)
- Add support for Intel icl++ compiler (Intel 2015 compiler) on MacOS X and Clang on linux system
- Add SSE and AVX support
- Add SSE and AVX code for 1/r kernel
- CMake improvements
