1.6: Better late than never

New Features

• Add Carthage support. You can now set the dependency_managers to one or
  more dependency management systems. Right now, this supports cocoapods and
  carthage. This also adds a --dependency-managers flag to the cli
  options. The --[no-]cocoapods option will be removed in a future version
  of Liftoff, and so should not be used going forward. The use_cocoapods
liftoffrc key has also been removed. You will now see a deprecation
  warning if you try to set this key. - Jake Craige
• Define custom build configurations. You can now set a build_configurations
  key in your liftoffrc to define custom build configurations that can be
  used elsewhere in your liftoffrc. These configurations need to be copies
  of either the release or debug schemes. See the liftoffrc man page for
  more info. - Marcelo Fabri (Thanks to Mark
  Adams)
• Define custom schemes in your liftoffrc. By default, this isn't set, but
  if you set schemes in your liftoffrc, Liftoff will generate a scheme
  with the specified actions. See the liftoffrc man page for more info. -

Changes

• bundle_version now uses git rev-list --count instead of git rev-list | wc -l | tr -d ' ' - Giovanni Lodi
• The default TODO and FIXME script now ignores Carthage source files in
  addition to CocoaPods source files. - Josh Steiner
• Improve test target detection. We were previously just matching against the
  word "Tests" instead of checking against the user-defined test target
  name. - Gordon Fontenot (Thanks to Oliver Halligon)

Bug Fixes

• Unset INSTALL_PATH for projects. We previously had this set to nothing,
  which caused problems where archiving an app would try to create a generic
  archive instead of an iOS app archive - Marcelo Fabri (Thanks
  to Jake Craige)
• Storyboards and XIBs are now properly treated as resources. Previously, they
  were added to Compile Sources, which could lead to crashes in some versions
  of Xcode. - Marcelo Fabri
