+Release Notes for CernVM-FS 2.10.1
+=================================
+
+CernVM-FS 2.10.1 is a patch release, containing several minor bug fixes and improvements.
+As with previous releases, upgrading clients should be seamless just by
+installing the new package from the repository. As usual, we recommend to update only a few worker nodes first and gradually ramp up once the new version proves
+to work correctly. Please take special care when upgrading a cvmfs client in NFS mode.
+
+For Stratum 1 servers, there should be no running snapshots during the upgrade.
+For publisher and gateway nodes, all transactions must be closed and no active
+leases must be present before upgrading.
+
+Packages are available for both the x86_64 and aarch64 architectures. This version starts to deprecate support for Ubuntu 16.04.
+
