NetworkManager 1.54.2 has been released today as the second maintenance update to the **NetworkManager 1.54** series of this popular open-source software for managing network connections inside a Linux-based operating system. NetworkManager 1.54.2 is a small update that only brings support for reapplying the `sriov.vfs` property (as long as “sriov.total-vfs” is not changed), support for configuring the HSR (High-availability Seamless Redundancy) protocol version via the `hsr.protocol-version` property, and support for configuring the HSR interlink port via the `hsr.interlink` property. NetworkManager 1.54.2 is available for download right now from its _GitLab page_ if you fancy compiling NetworkManager from sources. However, it is recommended that you wait for the new NetworkManager release to arrive in the stable software repositories of your GNU/Linux distribution before updating your installations. This release comes two months after NetworkManager 1.54.1, an even smaller update that only added support for a new rd.net.dhcp.client-id option in nm-initrd-generator and made the global-dns configuration overwrite DNS searches and options from connections, instead of merging them all together. NetworkManager 1.54 was released in August 2025 with major changes like support for configuring per-device IPv4 forwarding via the `ipv4.forwarding` connection property, OCI baremetal support in nm-cloud-setup, and support for configuring the loopback interface in NetworkManager’s text-based UI (nmtui). However, NetworkManager 1.56 is now in development as a major update that promises support for viewing and managing WireGuard peers in nmcli, support for accepting hostnames longer than 64 characters from DNS lookups, as well as support for configuring systemd-resolved’s DNSSEC option per-connection. NetworkManager 1.56 also promises support for reapplying “bond-port.vlans”, a gsm device-uid setting to restrict the devices the connection applies to, updated n-acd to always compile with eBPF enabled, as support for eBPF is now detected at run time, and the ability to treat modem connections that don’t have an operator code available as a recoverable error. NetworkManager 1.56 is available for public testing _here_. ### _Related_
