[Issue #245](https://github.com/capistrano/sshkit/issues/245),
[PR #246](https://github.com/capistrano/sshkit/pull/246)
@robd
* Now only color the output if it is associated with a tty,
or the `SSHKIT_COLOR` environment variable is set.
* Removed broken support for assigning an `IO` to the `output` config option.
[Issue #243](https://github.com/capistrano/sshkit/issues/243),
[PR #244](https://github.com/capistrano/sshkit/pull/244)
@robd
* Use `SSHKit.config.output = SSHKit::Formatter::SimpleText.new($stdin)` instead
* Added support for `:interaction_handler` option on commands.
[PR #234](https://github.com/capistrano/sshkit/pull/234),
[PR #242](https://github.com/capistrano/sshkit/pull/242)
@robd
* Removed partially supported `TRACE` log level.
[2aa7890](2aa78905f0)
@robd
* Add support for the `:strip` option to the `capture` method and strip by default on the `Local` backend.
[PR #239](https://github.com/capistrano/sshkit/pull/239),
[PR #249](https://github.com/capistrano/sshkit/pull/249)
@robd
* The `Local` backend now strips by default to be consistent with the `Netssh` one.
* This reverses change [7d15a9a](7d15a9aebf) 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 #235](https://github.com/capistrano/sshkit/pull/235),
[PR #237](https://github.com/capistrano/sshkit/pull/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](https://github.com/capistrano/sshkit/issues/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](https://github.com/capistrano/sshkit/issues/295)
* SSHKit now immediately raises a `NameError` if you try to set a formatter that does not exist. [#295](https://github.com/capistrano/sshkit/issues/295)
