Important: postal stuff in catacumba will be removed for the 1.0.0 (because after using it mayself I found it not very flexible approach) it has very little codebase so any one that already using it, can maintain the very small codebase for their own purposes

The only think I find very useful from the postal stuff is the way to establish bidirectional communication using websockets and send messages serialized using edn, that will be released as separated library...

I will do some library cleaning for the 1.0.0 removing useless and not very useful features, making the catacumba codebase more maintanable.

This is a list of stuff that will be removed: extensibility of handlers factory (hidden feature that is not documented and not very usefull), ring compatibility layer, postal
