To fix any issues due to migration, please go to the migration guide. Labels are clickable and lead to the section of the migration guide corresponding to the associated described change.

• indicates that some methods were deprecated;
• indicates a breaking change which could impact all users;
• indicates a breaking change impacting only custom IIDM implementations (most of the time, new IIDM methods/classes to implement). Note that this label is not added when another breaking change impacting all users is also present.
