Hi All,

I have just released v2.1.0 of reparse to opam. Below are the CHANGES for this release.  
CHANGES:

This release has backwards incompatible changes.

- Infix functions are now available (opened by default) in `Parser` module itself.
- Add support for let operators - `let+` , `let*` , `and+` and `and*` .
- `bind` and `map` function are now labelled following `base` library  
dependency convention.
- Items in `all_unit` are now `unit t` rather than `_ t` following monad  
combinator convention in `base` library dependency.
- `pure` is now deprecated. Use `return` instead. This is to stay consistent  
with monad conventions in `base` library dependency.
- `>|=` is deprecated. Use `>>|` instead. This is to stay consistent with monad  
conventions in `base` library dependency.
- Removed `map4` function.
- Add support for `ppx_let` .
- Deprecate `Parser` module. Use `Reparse` instead.

**Reparse**  
Reparse is a monadic, recursive descent based, comprehensive, parser construction library for ocaml.
