## [1.15.1][] (2017-11-18)

This is a small bug-fix release that fixes problems with `upload!` and \ 
`download!` that were inadvertently introduced in 1.15.0.

### Breaking changes

  * None

### Bug fixes

  * [#410](https://github.com/capistrano/sshkit/pull/410): fix NoMethodError \ 
when using upload!/download! with Pathnames - \ 
[@UnderpantsGnome](https://github.com/UnderpantsGnome)
  * [#411](https://github.com/capistrano/sshkit/pull/410): fix upload!/download! \ 
when using relative paths outside of `within` blocks -  \ 
[@Fjan](https://github.com/Fjan)

## [1.15.0][] (2017-11-03)

### New features

  * [#408](https://github.com/capistrano/sshkit/pull/408): upload! and download! \ 
now respect `within` - [@sj26](https://github.com/sj26)

### Potentially breaking changes

  * `upload!` and `download!` now support remote paths which are
    relative to the `within` working directory. They were previously documented
    as only supporting absolute paths, but relative paths still worked relative
    to the remote working directory. If you rely on the previous behaviour you
    may need to adjust your code.

## 1.10.0 (2016-04-22)

  * You can now opt-in to caching of SSH's known_hosts file for a speed boost

    \ 
[README](https://github.com/capistrano/sshkit/tree/v1.10.0#known-hosts-caching) \ 
for
    details. We plan to turn this on by default in a future version of SSHKit.

## 1.9.0

**Refer to the 1.9.0.rc1 release notes for a full list of new features, fixes,
and potentially breaking changes since SSHKit 1.8.1.** There are no changes
since 1.9.0.rc1.

## 1.9.0.rc1

### Potentially breaking changes

  * The SSHKit DSL is no longer automatically included when you `require` it.
    **This means you  must now explicitly `include SSHKit::DSL`.**
    See [PR #219](https://github.com/capistrano/sshkit/pull/219) for details.
    @beatrichartz
  * `SSHKit::Backend::Printer#test` now always returns true
    [PR #312](https://github.com/capistrano/sshkit/pull/312) @mikz

### New features

  * `SSHKit::Formatter::Abstract` now accepts an optional Hash of options
    [PR #308](https://github.com/capistrano/sshkit/pull/308) @mattbrictson
  * Add `SSHKit::Backend.current` so that Capistrano plugin authors can refactor
    helper methods and still have easy access to the currently-executing Backend
    without having to use global variables.
  * Add `SSHKit.config.default_runner` options that allows to override default \ 
command runner.
    This option also accepts a name of the custom runner class.
  * The ConnectionPool has been rewritten in this release to be more efficient
    and have a cleaner internal API. You can still completely disable the pool
    by setting `SSHKit::Backend::Netssh.pool.idle_timeout = 0`.
    @mattbrictson @byroot [PR #328](https://github.com/capistrano/sshkit/pull/328)

### Bug fixes

  * make sure working directory for commands is properly cleared after `within` \ 
blocks
    [PR #307](https://github.com/capistrano/sshkit/pull/307)
    @steved
  * display more accurate string for commands with spaces being output in \ 
`Formatter::Pretty`
    [PR #304](https://github.com/capistrano/sshkit/pull/304)
    @steved
    [PR #319](https://github.com/capistrano/sshkit/pull/319) @mattbrictson
  * Fix a race condition experienced in JRuby that could cause multi-server
    deploys to fail. [PR #322](https://github.com/capistrano/sshkit/pull/322)
