A note about timing and binaries:
Release 3.2.0 was tagged in commit e60d346 on August 8, 2023.
Conda binaries were never built for it (we couldn't) but it was released via DockerHub and can be accessed by docker pull reactionmechanismgenerator/rmg:3.2.0.
The corresponding "release" was not made on the GitHub platform until July 15, 2025, almost 2 years later.
