 Changelog
 ================================================================================
 
+v1.3.0
+--------------------------------------------------------------------------------
+* Improved output for non-TTY streams. Incremental output is not enabled.
+* Added an `autostart` option.  It defaults to `true`.  If set to `false`,
+  `#start` must explicitly be called.
+* The bar will no longer output multiple times if `#finish` is called when the
+  bar is already finished.  Same thing with `#stop`, `#resume`, `#pause`, etc.
+* Added `#remainder_mark` which will allow the user to set the character(s),
+  shown on the incomplete portion of the bar.
+* Enabled ANSI color codes to be used in the bar format and still have the bar
+  length properly represented.
+
 v1.2.0
 --------------------------------------------------------------------------------
 * Finally removed deprecation warning and made folder structure consistent
