## Changes between 1.0.0-beta1 and 1.0.0-beta2

### 3-arity of monger.collection/find-one-as-map now takes a vector of fields

3-arity of monger.collection/find-one-as-map now takes a vector of fields
instead of `keywordize` to better fit a more commonly needed case.

``` clojure
;; 3-arity in 1.0.0-beta1
(monger.collection/find-one-as-map "documents" { :first_name "John" } false)
```

``` clojure
;; 3-arity in 1.0.0-beta2
(monger.collection/find-one-as-map "documents" { :first_name "John" } [:first\_name, :last\_name, :age])
```


If you need to use `keywordize`, use 4-arity:

``` clojure
(monger.collection/find-one-as-map "documents" { :first_name "John" } [:first\_name, :last\_name, :age] false)
```
