+  **Warning**: Hotpatch upgrades from GitHub Enterprise Server version `3.11.0` to `3.11.1` will result in the instance losing network connectivity after a reboot. We have removed the hotpatch upgrade package for the `3.11.1` version of GitHub Enterprise Server to ensure this upgrade path is not executed accidentally. Before you upgrade, please make sure you have read the "[Known issues](#3.11.1-known-issues)" section of these release notes.
