# Changelog

## 0.6.1

- use subtree `gen/` for `CCGen` (symlink) rather than a copy.
- Add benchmarks for the function `iter` of iterators.
- `CCKTree`: more printers (to files), `Format` printer
- `CCOpt.get_lazy` convenience function
- introduce `CCFloat`, add float functions to `CCRandom` (thanks to @struktured)

## 0.6

#### breaking changes

- new `CCIO` module, much simpler, but incompatible interface
- renamed `CCIO` to `advanced.CCMonadIO`

#### other changes

- `CCMultiSet.{add_mult,remove_mult,update}`
- `CCVector.{top,top_exn}`
- `CCFun.compose_binop` (binary composition)

- new module `CCCache`
    * moved from `misc`
    * add `CCache`.{size,iter}
    * incompatible interface (functor -> values), much simpler to use
- `lwt/Lwt_actor` stub, for erlang-style concurrency (albeit much much more naive)
- `misc/Mixtbl` added from its old repository
- more benchmarks, with a more general system to select/run them
- more efficient versions of `CCList.{flatten,append,flat_map}`, some functions
  are now tailrec

## 0.3.3

- more functions in `CCPair`
- `CCCat`: funny (though useless) definitions inspired from Haskell
- `CCList`: applicative instance
- `CCString.init`
- `CCError.fail_printf`

## 0.3.2

- small change in makefile
