OBS 0.7.1

General:
* You can now use blank RTMP stream keys
* Changed volume meter to use decibels
* Added scaling filters (bicubic, lanczos)
* Added advanced audio properties dialog box (in the Edit menu), with features
  such as force mono, volume past 100%, and the ability to set the audio sync
  offset for each audio source
* Fixed a bug where a source's audio would not unmute when switching to a scene
  where that same audio source was in use
* Fixed possible FLV corruption bug that could happen under certain
  circumstances
* Fixed a potential crash that could happen when either recording or streaming
  was stopped
* Optimized frame output pipeline to ensure that no frames are unintentionally
  duplicated due to thread scheduling, improved the accuracy of frame timing,
  and improved the handling under higher CPU usage (and high-CPU presets)
* Fixed a few user interface flaws with the properties window where the
  properties section would get too big of would expand past its limits
* Fixed a user interface flaw with the volume mixer where the volume controls
  would expand to the right if the name was too long, making the volume sliders
  difficult to use
* Optimize frame handling of asynchronous video sources (such as video from
  capture devices), reducing CPU usage from what it was
* Projects now save whenever streaming/recording is started, and also at every
  20 second interval
* Fixed a UI bug where double-clicking with buttons other than the left button
  would still open up the properties of sources in the source list

Windows:
* Added new rewritten version of the game capture plugin, with improved
  performance and new features such as:
    - multi-adapter compatibility options (SLI/laptop)
    - option for pre-capture scaling (mostly for multi-adapter mode)
    - option for framerate limiting (also mostly for multi-adapter mode)
    - option to capture third-party overlays such as steam
    - option to automatically detect and capture any fullscreen window rather
      than have to select the window manually each time
    - safer hooking that's less prone to crashes in the target process, and
      that's safe to use with other hooks
* Added fast windows 8+ monitor capture support
* Added a 'Buffering' option to device capture that allows the user to select
  whether the signal should be buffered/timed or played right away
* Added an Activate/Deactivate button to device capture instead of it always
  being on
* Fixed an issue where the HD-PVR Rocket would not start up or shut down
  properly

Linux:
* Allow capturing of different X servers
* Improved multi-monitor support

Mac:
* Fixed possible crash when loading fonts for the text plugin
