== Version 2.3.1 - XXX, 2024 ==

This is mainly a bug-fix release. The bug only concerns the 3D-Var methods.

Bug correction:
 * Corrected convergence check for the CG+ solver in the 3D-Var methods in case of parallelized control vector.

New functionality:
 * Added initialization subroutines to initialize quantities of 'thisobs' in PDAF-OMI, e.g. for thisobs%doassim there is the routine PDAFomi_set_doassim. These are optional and no code changes are required. These routines are also provided for the arrays 'id_obs_p', 'icoeff_p' and 'domainsize'. Using these avoid the need to allocate the arrays in the user code. This should make the implementation in programming languages like C. The descriptions of the new functions are linked in https://pdaf.awi.de/trac/wiki/OMI_observation_modules.
