v0.17.0

• [breaking] Switched --data-value and --data-value-env to interpret values as strings by default (doc)
  • to get previous behaviour use explicit --data-value-yaml or --data-value-env-yaml
• [breaking] Changed --output to --output-directory flag, and --output-type to --output
  • this is more consistent with other common CLIs (e.g. -o json works as expected now)
• [breaking] Disabled text templating in YAML strings by default (doc)
  • add @yaml/text-templated-strings annotation to enable text templating for a YAML node
  • this makes ytt compatible by default with YAML documents that use (@ in values, e.g. for JSON path
• Added ability to use text templating in map item keys
  • now key_(@= i @): #@ i would work (though see item above on how to enable this)
• Support specifying filename for piped files via ytt -f file.yml=<(...)
• Improved error message for reserved keywords
• Changed backtrace format in errors to show file pos on each shown line
• Fixed use of annotations in a loop
• [experimental] Add --strict mode for YAML parsing (doc)
• [experimental] First pass at fixing YAML anchors with sequences
  • annotations do not quire work within anchored content

v0.14.0

• Fixed --file-mark=file.txt:type=text-plain
• Fixed --file-mark=file.yml:type=yaml-plain for templates that include text templates within strings

  • pos type is useful to determine what modified particular section of the file
