@@ -16,6 +16,23 @@ Two other Git Mirrors are available for GnuCOBOL:
 * [GnuCOBOL Documentation](https://sourceforge.net/p/gnucobol/code/HEAD/tree/external-doc/) is mirrored on https://github.com/ocamlpro/gnucobol-docs
 * [GnuCOBOL Contribution Tree](https://sourceforge.net/p/gnucobol/contrib/HEAD/tree/) is mirrored on https://github.com/ocamlpro/gnucobol-contrib
 
+### History
+
+A previous version of this mirror was used from February 2022 to
+January 2024. It has been moved to
+https://github.com/ocamlpro/gnucobol2 . It was deprecated in favor of
+this one, because it only contained a truncated history of the SVN
+repository.
+
+Pull-Requests made on that repository are still available here:
+https://github.com/ocamlpro/gnucobol2/pulls
+
+Since these two mirrors have no common history, former pull-requests
+cannot be merged directly in this repository. Instead, we advise
+former users to squash all their commits in one single commit, extract
+it as a patch, and regenerate a new branch on this repository by
+applying the patch.
