OpenELEC_Helix (Milhouse) - Version: devel-20140503005248-r18321-gb5520e3

Based on tip of OpenELEC master (b5520e3, changelog) and tip of XBMC master (adf6587, changelog) with the following modifications:

• Includes newclock3 (except for 6965cbf, a patch to avoid hammering the GUI, which has been replaced with a static spinner)
  
• Includes Python regex package for evaluation purposes. Initial benchmarking indicates generally positive (and in some cases, significant) performance gains. See this post for a description of how to test effectiveness of this package with addons
  
• Excludes the OpenELEC linux-01-RPi_support-4b3694f patch in favour of sourcing these and possibly more recent patches directly from kernel branch rpi-3.14.y
  
• Excludes the OpenELEC xbmc-master-newclock3 patch in favour of sourcing these and possibly more recent patches directly from newclock3 branch
  
• Default setting for "Show RSS Feed" changed to disabled
  
• Disabled "Total Duration" in Confluence (see build #0221 for details)
  
• ALSA is enabled and any suitable hardware should be available in XBMC Audio Settings
  
• FIQ FSM is enabled by default. See initial post for more details.
  

Build Highlights:

   • mediacenter: fix build of addon stuff if XBMC=master
     
2. kernel 3.14.y:
   • The Latest FIQ FSM requires CMA - enable with the following patch:
