As of 2023, the vast majority of the time someone says Hall algebra they mean something more general than for finite abelian groups. Usually it refers to a quiver but sometimes a curve. Also there are cohomological and K theoretic versions that deserve at least some mention. ( Maybe a new article for those?) I propose (and am willing to take on supposing no serious opposition) an update to this article to make reference to more general hall algebras that are more often discussed nowadays.
