Start your planning for 1.6 here:
In addition to integrating pending bugfixes, I'd like to see us focus on these items for 1.6:
- Conditional reader/feature expressions
- move to new ASM
- multiple build targets/profiles
- Many motivations for this: debug builds, lean builds for constrained environments, friendly REPL environment for development, specialized features for compiler and tool builders, etc.
- get CI to allow bugfix build from a clojure branch
- add C# style async blocks
