Recent development history:

v 2.6.8.20rc3
=========================================================================
x Partially restored "Allow local links" functionality (works for HTML
  file:// links but not for embedded resources and scripted loads)
+ "allowLocalLinks.from" about:config preference to define a whitelist
  (in ABE URL pattern list syntax) which, if valid and not empty,
  overrides the JavaScript whitelist which is reused by legacy default
  for pages allowed to open file:// links (Gecko 28 and above)
+ "allowLocalLinks.to" about:config preference to define a whitelist
  (in ABE URL pattern list syntax) which, if valid and not empty,
  limits the file:// links which can be opened by allowed pages
  (Gecko 28 and above)
- Removed "Allow rich text copy and paste from external clipboard" option
  from the UI if the browser doesn't support CAPS (Gecko 28 and above)

v 2.6.8.20rc2
=========================================================================
x Implemented early permission changes enforcement on not yet reloaded
  pages, to better match the old CAPS-based behavior (thanks therube
  for reporting)

v 2.6.8.20rc1
=========================================================================
x [Surrogates] Fixed Google Analytics surrogate breaking some javascript:
  links (thanks Will for reporting)
x [L18n] Fixed Finnish typo (thanks Kalle Niemitalo for reporting)
x [XSS] Removed OAuth-triggered false positive (thanks Gunnar Scherf for
  reporting)
