Major changes

* New feature! Ability to set `endsWith` to match paths like `/test?query=string` and ignore the query string * Remove `isarray` * Explicitly handle trailing delimiters instead of trimming them (e.g. `/test/` is now treated as `/test/` instead of `/test` when matching) * Remove overloaded `keys` argument that accepts `options` * Remove `keys` list attached to the `RegExp` output * Remove asterisk functionality (it's a real pain to properly encode) * Change `tokensToFunction` (e.g. `compile`) to accept an `encode` function for pretty encoding (e.g. pass your own implementation)

 Path-To-RegExp breaks compatibility with Express <= `4.x`:
 
-* No longer a direct conversion to a RegExp with sugar on top - it's a path matcher with named and unnamed matching groups
- * It's unlikely you previously abused this feature, it's rare and you could always use a RegExp instead
-* All matching RegExp special characters can be used in a matching group. E.g. `/:user(.*)`
- * Other RegExp features are not support - no nested matching groups, non-capturing groups or look aheads
+* RegExp special characters can only be used in a parameter
+ * Express.js 4.x used all `RegExp` special characters regardless of position - this considered a bug
 * Parameters have suffixes that augment meaning - `*`, `+` and `?`. E.g. `/:user*`
+* No wildcard asterisk (`*`) - use parameters instead (`(.*)`)
