+== Version 3.1.1 - May 27, 2026 ==
+
+This is a bug-fix release. The bug was introduced in PDAF V3.0beta when revising the PDAF-internal observation handling. It only occurs in the localized ensemble filters under special conditions.
+
+** Bug corrections **
+
+- Corrected application of observation operator routine introduced with PDAF V3.0beta in local ensemble filters. Under certain conditions when with parallelization a process sub-domain would have zero observations, the program could  get stuck ('deadlock'). (The particular settings are thisobs%use_global_obs=0 and observe_ens=.true.; both of which are not the default settings)
+
+** Further changes **
+
+- Added internally a deallocation of local observation information for PDAF-OMI. Without this, it might be that when running with OpenMP parallelization some threads might not correctly free the memory.
+- Revised implementation recommendation for init_dim_obs_pdafomi in callback_obs_pdafomi.F90. Now the overall number of observation is incremented in step-wise instead of using a sum over all obervation types at the end of the routine. This simplified the addition of further observation types.

 This is a feature release with performance improvements and new functionality. All changes are backward compatible within PDAF3. Thus, one can use PDAF 3.1 without any changes to codes existing for PDAF 3.0.

  - we included the use of an interface module ''mod_model_pdaf'', which is intended to be the only place to directly include modules of the model. Thus, all user routines for PDAF include only ''mod_model_pdaf'' instead of different model modules. This leads to a cleaner source code and allows us to use in many cases identical source files for online and offline coupling. 
  - we added the module ''mod_statevector_pdaf'' to provide a structured way to initialize the setup of the statevector for multiple model fields. Its use is demonstrated in ''tutorial/online_2D_serialmodel_2fields''.
