remove_cg_new with last commit 5f1038eb FAIL: Updates tolerances. by NicolasTD towards_photon_as_system with last commit 6665a59e FAIL: Minor code improvements. by NicolasTD pseudo_sigma_erf with last commit 7e83b8bd FAIL: Fix the corner case in which the short-range part is zero. by NicolasTD revisit_spline_cutoffradius with last commit ca7200ac PASS: Splines now store their own cutoff radius by NicolasTD
• FCD_propagator_new with last commit aeee1048: added fcd wavepacket no field test by jasonkaye
improve_slater with last commit 28de19bd PASS: Minor improvements to the Slater potential. by NicolasTD improve_spinors_low_magnetization_limit with last commit 74cb24e2 PASS: Changes the treatment of the low magnetization limit for LSDA with spinors. Now, a relative tolerance is introduced and in the case of lower tolerance, the system is assumed to be collinear, to avoid numerical instabilities. by NicolasTD stress/ewald_2D with last commit dbec1964 PASS: Some changes following Alex's comments. by NicolasTD
• optim/magnetic_terms with last commit 7aaf7dd6: Optimizes the local potential and the magnetic term for spinors. by NicolasTD
• pseudo_as_classes with last commit 5f2a32af: Rewrites the species as classes by NicolasTD
main with last commit c05b4533 PASS: Merge branch 'fix-typos-in-tutorials' into 'main' by Nicolas Tancogne-Dejean remove_accel_sync with last commit 9d159885 FAIL: Remove unnecessary GPU synchronizations by NicolasTD reduce_dependencies with last commit 3e05a5c6 FAIL: Add some doxygen. by Micael Oliveira
• photon_free_exchange_develop with last commit 520a8555: fix the pxLDA for 2D cases using the conjugate gradient method by I-Te LU
better_update_couplings with last commit 91f3beaa FAIL: Remove assertions that quantities have been marked as required when updating interactions, as setting quantities needed by the interactions is done automatically by the framework. For the same reason, remove setting quantities as required in a few places. by Micael Oliveira fix_static_magnetic_field with last commit c8ab8a7f FAIL: Fix some minus signs that were included in the code because of the prior bugs. by NicolasTD
• add_shift_to_bessel with last commit be83ef2d: Add bessel shift option by Ilke Albar

• mp2_density_matrix with last commit 8e2246e3: findent fix by Francesco Troisi
