I have heard in the past that MTL's maintainers are very conservative about pushing out new releases, because so much of tho Haskell ecosystem needs to be updated and rebuilt when they do. But the backlash seems to be cramming as much as possible into new releases. This is not ideal but it is pragmatic.
I don't accept the assumption that "much of the Haskell ecosystem needs to be updated and rebuilt when a new release of mtl is made". Packages that properly indicate upper bounds on their mtl dependency won't be affected (assuming a major version bump). The burden lies with those who want to use the new features: they need to convince other library maintainers to release compatibility updates with raised upper bounds on their mtl dependency, issuing PRs and lobbying for new releases. This is exactly as it should be. Cheers Ben -- I would rather have questions that cannot be answered, than answers that cannot be questioned. -- Richard Feynman
