+## 2.0.0 (2015-04-23)
+
+* Rewritten Xvfb launch using Process.spawn and avoiding a shell
+* Do not manually remove X11 lock file when stopping Xvfb; this isn’t conventional. Should eliminate some errors with not being able to find Xvfb
+* More informative error messages
+* Detect situation when Xvfb can’t listen to any sockets and raise corresponding error.
+* If video recorder provider is libav, use avconv binary instead of ffmpeg
+* Fixes to video recorder launch options (from @gpavlidi, @abotalov, @ynagorny, @WeAreFarmGeek)
+* Customize launch timeout (from @ShockwaveNN)
+* Properly working integration tests
+
 ## 1.0.2 (2014-06-03)

 # Headless [![Travis CI status](https://secure.travis-ci.org/leonid-shevtsov/headless.png)](http://travis-ci.org/leonid-shevtsov/headless)
 
-Headless is *the* Ruby interface for Xvfb. It allows you to create a headless display straight from Ruby code, hiding some low-level action.
-It can also capture images and video from the virtual framebuffer.
+Headless is *the* Ruby interface for Xvfb. It allows you to create a headless display straight from Ruby code, hiding the low-level action.
+It can also capture images and video from the virtual framebuffer. For example, you can record screenshots and screencasts of your failing integration specs.
 
 I created it so I can run Selenium tests in Cucumber without any shell scripting. Even more, you can go headless only when you run tests against Selenium.
 Other possible uses include pdf generation with `wkhtmltopdf`, or screenshotting.

+### Display socket is taken but lock file is missing
 
----
+This means that there is an X server that is taking up the chosen display number, but its lock file is missing. This is an exceptional situation. Please stop the server process manually (`pkill Xvfb`) and open an issue.

+### Video not recording

+If video is not recording, and there are no visible exceptions, try passing the following option to Headless to figure out the reason: `Headless.new(video: {log_file_path: STDERR})`. In particular, there are some issues with the version of avconv packaged with Ubuntu 12.04 - an outdated release, but still in use on Travis.
