[2.0.0]

Added

• ReplaceNullValue — configuration option (KeyInjectConfiguration.ReplaceNullValue, default is true') and the builder's method is SetReplaceNullValue(bool)`.
  • When ** is true** (default behavior): if there is no value in the configuration for the placeholder or it is empty, substitution is performed with an empty string (for example, name=${MISSING} → name=).
  • When false: such placeholders are not replaced, and the original template remains in the string (for example, ${MISSING}).
