Evolution of the code:

version 4.0, December 2022: Rafael Almada, Jean-Paul Ampuero, Etienne Bachmann, Kangchen Bai, Stephen Beller, Jordan Bishop, Alexis Bottero, Emanuele Casarotti, Clement Durochat, Rene Gassmoeller, Hom Nath Gharti, Leopold Grinberg, Aakash Gupta, Foivos Karakostas, Dimitri Komatitsch, Qinya Liu, Geordie McBain, Ryan Modrak, Vadim Monteiller, Masaru Nagaso, Elif Oral, Daniel Peter, Elliott Sales de Andrade, James Smith, Carl Tape, Eduardo Valero Cano, Huihui Weng, Zhinan Xie: various code improvements (fault solver, FK/DSM/AxiSEM coupling, gravity perturbations, energy integrals); inverse problem module; parallel heuristic mesh decomposer; ADIOS2 file I/O support; ASDF seismogram output; HIP GPU support.

version 3.0, December 2014: many developers. Convolutional PML, LDDRK time scheme, bulk attenuation support, simultaneous MPI runs, ADIOS file I/O support, new seismogram names, Deville routines for additional GLL degrees, tomography tools, unit/regression test framework, improved CUDA GPUs performance, additonal GEOCUBIT support, better make compilation, git versioning system.

version 2.1, July 2012: Max Rietmann, Peter Messmer, Daniel Peter, Dimitri Komatitsch, Joseph Charles, Zhinan Xie: support for CUDA GPUs, better CFL stability for the Stacey absorbing conditions.
