v6.4.0-RC2

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.
