 * Revision of the initialization of observations: Now the observations are initialized before the actual analysis step is computed. Also the observartion operator is called before the actual analysis step. This also allows the option to initialize observations before prepoststep_pdaf is called for the forecast ensemble. Related to this the screen output for the observations was revised and is displayed at a different location from before
 * New PDAF3 interface: The selection of possible calls to PDAF*_put_state and PDAF*_assimilate has grown over the years. We introduced a new interface PDAF3_assimilate_X and PDAF3_put_state_X, which uses the latesd features that were introduced in previous PDAF releases and allows for a minimum number of arguments. The previous routines still exist, but we recommend to change to the new routines.
-* Change for flexible parallelization variant: For this variant it is now possible to use PDAF_assimilate routines, while PDAF_put_state routines had to be called before. Using PDAF_assimilate is the recommend choice for PDAF V3. Since PDAF_assimilate routines are clled at each time step during the forecast phase this allows to easy use of the IAU functionality.
+* New routine PDAF_get_fcst_info: This routine allows to retrieve the return values of PDAF_get_state (nsteps, time, doexit) for the case that PDAF_assimilate routines, which do not return these values, are used.
+* Change for flexible parallelization variant: For this variant it is now possible to use PDAF_assimilate routines, while PDAF_put_state routines had to be called before. Using PDAF_assimilate in combination with 'PDAF_get_fcst_info' is the recommend choice for PDAF V3. Since PDAF_assimilate routines are called at each time step during the forecast phase this allows to easy use of the IAU functionality.
 * Added observation diagnostics module for OMI: This is a set of routines that give the user access to the observation information including the observed ensemble and the observed ensemble mean. In addition, there are routines computing statistics for the difference beetween the observations and the observed ensemble mean.
 * New routine PDAFomi_set_localize_covar: This routine is called in the OMI observation module in init_dim_obs_pdafomi. It sets the information for localization in the LEnKF and ENSRF/EAKF methods. (optional for LEnKF)
