Release notes

• [Plugins] If multiple plugins define the same YAML file (generator, mod element definition, variable, ...), the contents of those files will be merged (lists and maps merged, scalar entries loaded first only), considering plugin order based on weight. Plugins should update their YAML files to contain minimal changes to templates, not contain full overrides, as was the practice so far.
