In this article, the author explains the Erlang `pg` module, which represents process groups, and its relation to the older `pg2` module. The author notes that `pg` is the more modern implementation and elaborates on its advantages, such as treating empty and non-existent groups similarly and not requiring cluster locks. This article serves as an informative piece for those interested in the foundational elements of Erlang, particularly in the context of process management.
