## [Unreleased]


## [6.0.1] - 2020-01-30
### Fixed
- `metrics-curl.rb`: improved platform support for detecting `curl` using `which` due to inconsistent options across non bash shells, tested on `bash` and `dash` shells (@elfranne)

## [6.0.0] - 2020-01-17
### Added
- New metrics-libcurl.rb  metrics check that works directly with libcurl and does not need curl executable on system. Very useful as an asset in containerized Sensu Agent installs.
- `check-http.rb`: Add `HEAD` to method options
- `check-http.rb` Added option to include file with multiple headers, useful for long list of headers.

### Fixed
- Updated asset build automation for Alpine target to ensure curl and libcurl based metrics work.
- `check-http.rb`: An empty response body when using `-w` no longer creates a potentially confusing `no implicit conversion of nil into String` error

### Changed
- Updated bundler development dependancy to '~> 2.1'
- Make rake Kitchen tasks conditional on ability to load kitchen module in development env.  kitchen module will not load on hosts without docker runtime.
