• Added: New validation expressionDoesNotUseLabelsForMetricRegexp
• Added: New validation expressionUsesOnlyAllowedLabelValuesForMetricRegexp

v3.6.2

• Fixed: Invalid internal name of the newExpressionDoesNotUseClassicHistogramBucketOperations validator causing that it wasn't possible to disable the validator

v3.6.1

v3.6.0

• Added: Configuration file can now be in Jsonnet format if the config file name ends with .jsonnet and it will get automatically evaluated.

v3.5.0

• Added: New validation expressionDoesNotUseClassicHistogramBucketOperations to avoid queries fragile because of the classic histogram bucket operations.
  See the docs for more info expressionDoesNotUseClassicHistogramBucketOperations
• Changed: ⚠️ revert the ENV expansion in config file since it was breaking and caused issues (it was a stupid idea)
• Fix: Avoid panic when validating unsupported file type and revert to previous behavior when any file was treated as a rule file regardless of the extension.
  The only exception are .jsonnet files that are evaluated first.
