* Added ctx object to all system struct's constructors by @aelsabbahy in gh#837
* Changed: Reworded syntax error messages to be clearer by @aelsabbahy in gh#838
* Fix json by @aelsabbahy in gh#841
* Command empty strings by @aelsabbahy in gh#839
* Added: goss-darwin-arm64 binary to release by @aelsabbahy in gh#835
* Goss v0.4.X introduces some major enhancements to the matching logic allowing far more flexibility for asserts.
* For example, can assert that the output of echo "3" is less than 5.
* Added: transforms support (closes gh#538)
* Allows comparison of string to int, ex: ensuring a systctl output below/above a specific number (closes gh#220)
* Allows JSON parsing/validation support (closes gh#578)
* Allows comparing command output to a string, this will display the failed output on failure (closes gh#483)
* -o include_raw will show the non-transformed value
* Added: Some new matchers
* equal matcher added to do strict type comparison (e.x. string to string)
* contain-substring
* have-patterns - This mimics the existing default behavior of file contents and command output
* contain-elements - checks that an array value matches a set of matchers
* Added: runlevels support for service
* Added: option to sort output (closes gh#416)
* Added: All resources now support key override (closes gh#518, closes gh#742)
* Added: Use exit code 78 if test file is unparseable (closes gh#317)
* Changed: removed alpha from non-linux binary names
* Changed: StartTime is no longer calculated from goss start. Calculated from first test start, this allows accurate reporting when showing a cached result
* Changed: Completely re-worked matchers and shared output logic
* Changed: Cache test results in serve instead of output (closes gh#612)
* Added: Significantly improved test coverage of matcher, output code
* Changed: Doc to reference cat -E /proc/<PID>/comm to avoid whitespace issues (closes gh#762)
* Changed: Removed file.Size from autoadd (closes gh#262)
* Added: matcher.as-reader this allows the matcher string to behave as an io.Reader output. Can be useful for testing
* Removed: json_online output format, use: goss v -f json -o oneline
* Added: windows and darwin alpha binaries back in the release (gh#829)
