As for many major releases of medini, there have been some improvements and modifications of the metamodel. This time the changes were somewhat bigger in the sense that the effect to the scripting API and scripts especially for HARA is significant. This article gives a overview on the changes and quick guidance in case a script need adaptation.
In short: The HARA metamodel was changed with 2019 R1, mainly due to separation between HARA (ISO Automotive) and FHA (ARP Aviation). Attributes were either (1) renamed, (2) moved or (3) prefixed with "ISO26262". That mainly impacts constraints, scrips and reports using scripts.
Attached to this article are two example projects with scripts for 19.2 and 2019 R1 (internal number is 19.3) - check them to understand the changes or see this script overview script that script shows all changes in a single example:
var he = finder.findByType(Metamodel.hazard.HazardousEvent).first(); // <-- same as 19.2
console.log("GENERAL");
console.log("ID: {0}", he.id); // <-- same as 19.2
