## 0.7

#### breaking

    `containers.sexp`, `containers.data`)

#### other changes

- `sexp`:
    * `CCSexp` now splitted into `CCSexp` (manipulating expressions) and `CCSexpStream`

- `core`:
    * `CCString.fold`
    * `CCstring.suffix`
    * more efficient `CCString.init`
    * fix errors in documentation of `CCString` (slightly over-reaching sed)

- new `containers.bigarray`, with `CCBigstring`
- `CCHashtbl.map_list`
- `io`:
    * `CCIO.read_all` now with ?size parameter

    * bugfix in `CCIO.read_all` and `CCIO.read_chunks`
- use `-no-alias-deps`

## 0.6.1
