capri:star [2017/01/18 13:36] – Adding maintenance release 1.2 torbjornjcapri:star [2018/02/09 13:51] – Updating release notes for including STAR 2.0 torbjornj

-====== Release notes (cumulative) ======+===== Release notes (cumulative) ===== 
 + 
 +=== STAR 2.0 === 
 + 
 +This new series of releases contains two key modifications: 
 + 
 +  * It calibrates to the CAP post 2014 instead of the old MTR scenario. This required adding the first-order conditions of the greening restrictions in the PMP algorithm, which was not trivial. 
 +  * It includes the possibility to set BREXIT ON when building the database. This allows the user to build a model where the UK is a separate market model region with bilateral trade instruments with the EU. This is now the standard setting, albeit it implements free trade between UK and EU27. 
 + 
 +Some modifications that were scheduled for this release were not included, because they were not sufficiently stable in testing at the key date for the release. In particular, the following components are essentially unchanged from STAR 1.3 but scheduled for inclusion in a subsequent release. 
 + 
 +  * Revision of the fertilizer distribution. This was found to be numerically unstable in STAR 1.0, and is still so as testing revealed. 
 +  * Revision of the feed distribution to give more stable results and a more plausible allocation of feeding stuffs. 
 + 
 +Finally, this release has some known issues in addition to the points mentioned above: 
 + 
 +  * New Norwegian data was made available but not in time to complete the testing phase. 
 +  * There are occasional problems to reproduce the baseline in 2030 when market and supply are allowed to interact. The precise circumstances causing this to happen are still unclear. 
 + 
 +=== STAR 1.3 === 
 +A maintenance release addressing the following issue in STAR 1.2: 
 +  *Including the most recent Graphical User Interface (GUI) 
 +  *A bug with the Basic Payment Scheme in Greece led to missing payments in several Greek regions. 
 +  *Changing the way the grassland maintenance requirement works in Greening (lower bound on grass land) 
 +  *Modified reporting for EU28 
 +  *Modified report tables for the GUI 
 + 
 +It was observed that when the GUI batch execution file "build_database_and_baseline.txt" was executed with this model version, the baseline calibration of the market model sometimes failed.In that case, a manual re-start of that task directly from the GUI using the default settings worked. 
 +Furthermore, it was observed that the baseline reproduction run (i.e. calibrating to mtr_rd_cal and then simulating mtr_rd_ref) resulted in small changes in some of the "new" member states, in particular Serbia.
