+### Added
+
+- Added the `-aureus.bless` test flag, which "blesses" the output of a failing
+  test, accepting it as correct for future test runs. For file-based tests it
+  replaces the entire output file with the failing output. For Markdown tests it
+  replaces the code within the fenced code block.
