• Add support for the :strip option to the capture method and strip by default on the Local backend.
  PR #239,
  PR #249
  @robd
  • The Local backend now strips by default to be consistent with the Netssh one.
  • This reverses change 7d15a9a to the Local capture API to remove stripping by default.
  • If you require the raw, unstripped output, pass the strip: false option: capture(:ls, strip: false)
• Simplified backend hierarchy.

  PR #237
  @robd
  • Moved duplicate implementations of make, rake, test, capture, background on to Abstract backend.
  • Backend implementations now only need to implement execute_command, upload! and download!
  • Removed Printer from backend hierarchy for Local and Netssh backends (they now just extend Abstract)
  • Removed unused Net::SSH:LogLevelShim
• Removed dependency on the colorize gem. SSHKit now implements its own ANSI color logic, with no external dependencies. Note that SSHKit now only supports the :bold or plain modes. Other modes will be gracefully ignored. #263
• New API for setting the formatter: use_format. This differs from format= in that it accepts options or arguments that will be passed to the formatter's constructor. The format= syntax will be deprecated in a future release. #295
• SSHKit now immediately raises a NameError if you try to set a formatter that does not exist. #295

1.7.1

• Fix a regression in 1.7.0 that caused command completion messages to be removed from log output. @mattbrictson
