Fixed bug where the old ithemes-updater-object global was being referenced.
1.1.0 - 2013-10-04 - Chris Jean
Enhancement: Added handler for GET query variable: ithemes-updater-force-minor-update.
Bug Fix: Changed URL regex for applying the CA patch to only apply to links for api.ithemes.com and not the S3 links.
Bug Fix: A check to ensure that the $GLOBALS['ithemes_updater_path'] variable is set properly.
Misc: Updated file reference for ca/cacert.crt to ca/roots.crt.
1.2.0 - 2013-10-23 - Chris Jean.
Enhancement: Added the quick_releases setting.
Enhancement: Added an explicit flush when the ithemes-updater-force-minor-update query variable is used
Misc: Removed the show_on_sites setting as it is no longer needed.
