I'm happy someone's challenging the Rails almost-monoculture in the Ruby ecosystem, but Hanami doesn't seem to bring much to the table. Is there anything in this release that Rails hasn't had for years?
I think what Hanami had to bring to the table is already on the table for years - slice architecture, repository pattern, true view layer, explicit dependency management and perhaps one that it recent - first class operations support. This release indeed does not bring a lot in that matter, rather fills the gaps in the ecosystem and DX.
That statement means nothing. You could say the exact same thing about Rails and have an equally defensible position. What about its architecture makes it better?
It is not, Hanami is a batteries-included framework. It not even a pay-as-you-go framework like Pyramid. The equivalent of Flask in Ruby land is Roda+Sequel.
