 ===== Release notes (cumulative) =====
+=== STAR 2.4 ===
+This maintenance release addresses ...
+  * Pillar 1 payments of the CAP were missing for "new" member states when running CAP 2014-2020 for a year before 2020.
+  * Several minor tweaks and fixes.
+=== STAR 2.3 ===
+This maintenance release addresses stability of feeding, reporting for fertilizers, and also includes some cleaning up of code:
+  * The feed distribution was revised to become more stable under repeated starts (P. Witzke)
+  * Several options were removed from the GUI with respect to the estimation of GHG emission trends
+  * A large pack of updates to the GHG emission estimations were imported from the development branch ClipByFood
+  * The inner fertilizer allocation model can be turned OFF in simulations (on by default)
+  * The GUI now reports a decomposition of the NUTNED_ equation, accessible under the theme "Fertilization"
+  * Some items were excluded from checks in COCO to make the program run through with GAMS 25.0 and 25.1
+  * The legacy data set on ghg emissions from EDGAR was removed.
+=== STAR 2.2 ===
+This maintenance release resolves several important calibration issues.
+  * The market model did not calibrate properly due to an inconsistently included "BREXIT" policy
+  * The supply models did not calibrate properly due to missing parameters for manure trade
+  * The stability tests did not give true results due to an inconsistent use of results_in and results_out, essentially mixing fertilizer parameters of two runs
+  * Several minor bug fixes, e.g. in linking supply and demand and scaling of NMIN
+  * A final overhaul of feeding is still due in Maintenance Release 2.3.
+=== STAR 2.1 ===
+This maintenance release implements the revised treatment of fertilizers and feed. For fertilizers, a bi-level programming approach has been implemented, where the flows of fertilizers are modelled as a Bayesian estimator ensuring an interior solution that is "close to" the calibrated flows when simulating and close to a prior distribution when calibrating. For feed, the distribution of feeding stuffs to animals was revised to improve plausibility and stability, but without principal changes of the way the model works.
+In addition to the feed and fertilizer modifications, the following bugs or minor issues were addressed:
+  * Changing the order of work steps and tasks in the GUI to reflect the order in which the steps can be carried out (e.g. FAOSTAT first)
+  * An issue with price experiments in Threads-mode was resolved
+  * Start at an infrastructure to report the results of the fertilizer allocation to DATAOUT (reports\fert_dist_results.gms)
+  * Relaxing the winter cover requirement in one Finnish region to avoid infeasibility in baselines.
+  * The income computations for EAA had inconsistent prices for FODDER, so that the regional farms had costs <> revenues for fodder, which should not be possible.
+  * The Dual Analysis of the supply models had not updated versions of some constraints, so that there were an "unexplained rest". (sugar beet and greening restrictions)
+Finally, the testing routines were augmented and slightly revised, to include individual testing of simulations with supply and market models standalone.
