 ChangeLog
 =========
 
+4.2.2 (2017-01-02)
+------------------
+
+* #72: Handling clients that send invalid `Content-Length` headers.
+
+
 4.2.1 (2016-01-06)
 ------------------
 
 * #56: `getBodyAsString` now returns at most as many bytes as the contents of
   the `Content-Length` header. This allows users to pass much larger strings
   without having to copy and truncate them.
+* The client now sets a default `User-Agent` header identifying this library.
 
 
 4.2.0 (2016-01-04)
 ------------------
 
 * This package now supports sabre/event 3.0.
-* The client now sets a default `User-Agent` header identifying this library.

+* #16: Correctly parse urls that are only a fragment `#`.
+
+
+1.2.0 (2016-12-06)
+------------------
+
+* Now throwing `InvalidUriException` if a uri passed to the `parse` function
+  is invalid or could not be parsed.
+* #11: Fix support for URIs that start with a triple slash. PHP's `parse_uri()`
+  doesn't support them, so we now have a pure-php fallback in case it fails.
+* #9: Fix support for relative URI's that have a non-uri encoded colon `:` in
+  them.
+
+
+1.1.1 (2016-10-27)
+------------------
+
+* #10: Correctly support file:// URIs in the build() method. (@yuloh)
