-# the latest release) carries mbo/diff's rich API (unified/context/normal/side-by-side formats,
-# myers/naive/direct engines, the empty-time_format git-style header, ignore_missing_final_newline)
-# and mbo/digest (the -hash algorithms). Pinned at the mbo main commit merging helly25/mbo#234.
-# DROP THIS for a plain `bazel_dep(... version = "0.13.0")` bump the moment mbo 0.13.0 hits the BCR.
