+ChangeLog
+=========
+
+1.1.0 (2016-03-07)
+------------------
+
+* #6: PHP's `parse_url()` corrupts strings if they contain certain
+  non ascii-characters such as Chinese or Hebrew. sabre/uri's `parse()`
+  function now percent-encodes these characters beforehand.
+
+
+1.0.1 (2015-04-28)
+------------------
+
+* #4: Using php-cs-fixer to automatically enforce conding standards.
+* #5: Resolving to and building `mailto:` urls were not correctly handled.
+
+
+1.0.0 (2015-01-27)
+------------------
+
+* Added a `normalize` function.
+* Added a `buildUri` function.
+* Fixed a bug in the `resolve` when only a new fragment is specified.
+
+San José, CalConnect XXXII release!
+
+0.0.1 (2014-11-17)
+------------------
+
+* First version!
+* Source was lifted from sabre/http package.
+* Provides a `resolve` and a `split` function.
+* Requires PHP 5.4.8 and up.

+sabre/uri
+=========
+
+sabre/uri is a lightweight library that provides several functions for working
+with URIs, staying true to the rules of [RFC3986][2].
+
+Partially inspired by [Node.js URL library][3], and created to solve real
+problems in PHP applications. 100% unitested and many tests are based on
+examples from RFC3986.
+
+The library provides the following functions:
+
+1. `resolve` to resolve relative urls.
+2. `normalize` to aid in comparing urls.
+3. `parse`, which works like PHP's [parse_url][6].
+4. `build` to do the exact opposite of `parse`.
+5. `split` to easily get the 'dirname' and 'basename' of a URL without all the
+   problems those two functions have.
