- change 'flag_add_coordinates' into 'flagAddCoordinates' in DbGrid::createSubGrid() and DbGrid::reset()
- Increase the size of the Enums from 32 to 40.
- Model::evalDriftMat() is replaced by Model::evalDriftMatrix()
- Model::covMatrixMS() is replaced by evalCovMatrixSymmetric()
- Model::covMatrixM() is replaced by evalCovMatrix()
- Model::covMatrixV() is replaced by evalCovMatrixV() (option added)
- Db::getActiveSampleNumber() (deprecated) is replaced by getSampleNumber(true)

=============
- Fix artifact upload/download for github action

=============
- Correct the functions evalCovMat() and evalDriftMat()
- Adding calculation of log-likelihood evaluation in the general case (class Model)
- Adding calculation of Log-Likelihood in SPDE
- Adding calculation of variance of estimation error in SPDE
- Updating internal procedures compare_test and update_test to allow personal reference files
(for any type of non-regression file)
- Correcting the multivariate heterotopic conditional simulations
- Improvements in the different Gibbs sampler versions + new tutorial
- Function matrix_qoci() becomes MatrixSquareSymmetric::minimizeWithConstraintsInPlace()
- Improvement of test_potential.cpp (include cross-validation)
