== 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 now the routine PDAFomi_set_doassim. These routines are optional so that no code changes are required. These routines are also provided for the arrays 'id_obs_p', 'icoeff_p' and 'domainsize' which avoid the need to allocate the arrays in the user code. This should make the implementation in programming languages like C easier. A list of the new initialization routines with links to their description is provided in https://pdaf.awi.de/trac/wiki/PDAFomi_additional_functionality.
