Linux Mint 27 is set to arrive next month, and it represents more than a routine upgrade. After roughly a year of development, the release introduces a new version number, a reworked release strategy, and a collection of system-level improvements that touch everything from laptop power management to file browsing and terminal use.
A new numbering scheme and release cadence
The jump from Mint 22 to Mint 27 reflects a deliberate shift in how the project names and schedules its releases. Earlier development snapshots carried the label Mint 23 “Alfa” as a while the team settled on a strategy. The final release is called Adrien, and going forward, version numbers will correspond to the upcoming year.
Lead developer Clement Lefebvre has explained that the old twice-a-year cycle was time-consuming and limited the team’s ability to take on larger changes. The new cadence removes point releases entirely, so the next version after 27 will be 28, then 29, and so on. Distribution titles will now use boys’ names rather than girls’ names. Lefebvre has described the decision as difficult but said the team is already seeing benefits, with projects and changes being implemented that would previously have seemed too ambitious.
Hibernation returns as a supported option
One of the most practical changes in Linux Mint 27 is the return of hibernation to the supported desktop configuration. A dedicated Sleep Modes page in the System Administration tool is designed to simplify enabling and configuring hibernation, including handling its swap-space requirements.
Lefebvre has explained why this matters. Closing a laptop lid typically triggers suspend mode, which continues to draw power. Users often forget the machine is not truly off, and if the battery runs out, the session is lost along with the charge. Hibernation saves the session to disk and fully shuts down the computer, so no power is used. When the lid is reopened, the session and the battery level are as they were.
Superlight replaces GNOME System Monitor
A new application called Superlight takes over system monitoring duties from GNOME System Monitor. It provides graphs for CPU, RAM, swap, GPU, network, disk I/O, temperature, and fan speed. It also offers per-application and per-process resource views, and on battery-equipped systems, it tracks charge and power-flow history.
Storage analysis is another notable part of Superlight. It can break down disk usage by files and folders, Steam games, and Flatpak applications. This brings common troubleshooting questions — what is using the CPU, and where did the disk space go — into a single interface.
Nemo gains a preview pane
The Nemo file manager now includes a media preview pane that can be toggled with F7 or a status-bar button. It supports pictures, audio, and video, and it displays associated information such as capture date and camera model for photographs. For users who work extensively from a file manager, this is a welcome addition.
Velocitty: a terminal built for session management
Mint’s new terminal application, Velocitty, is aimed at users who spend time in the shell. It offers a graphical tab overview, configurable color palettes, and tabs that can be reordered, moved between windows, or detached. Shells and startup commands are configurable, and users can create named, color-coded custom tabs with preset commands and optional automatic opening.
Tab colors are context-sensitive: red indicates elevated privileges, blue marks remote sessions, and a lighter shade signals running processes. The goal is to make recurring projects and SSH sessions easier to locate and reopen. Users who prefer other terminal programs are free to keep using them.
Unfold simplifies archive handling
Unfold is a new archive manager for viewing, creating, and extracting archives. It relies on 7-Zip and 7zip-RAR and supports the encryption formats those backends handle, including password-protected archives. Its design prioritizes simplicity over an extensive feature set.
Under the hood: Ubuntu base, installer, and Wayland
Linux Mint 27 is built on Ubuntu 26.04 LTS and will continue to offer Cinnamon, Xfce, and MATE desktops. The project is moving from Ubiquity to the Linux Mint Debian Edition live installer, which supports OEM bulk installations, BIOS and EFI systems, Secure Boot, and LVM/LUKS configurations. The release will use Linux kernel version 7.0, with the exact point release to be confirmed closer to launch.
Wayland compatibility remains a goal, but X11 is not disappearing. Lefebvre has said that in an ideal scenario, Wayland would work as well as X11, but the team is not there yet.
What the longer cycle delivers
The central change behind Linux Mint 27 is a cleanup of existing code. The longer development cycle gives the team room to overhaul several parts of the desktop together rather than squeezing individual improvements into six-month windows. Lefebvre has noted that he does not think he has ever seen so many changes and new features implemented for a single release.
For users, that means better laptop power management, more capable built-in utilities, and a more complete set of everyday desktop applications. The updated release is expected to ship with GIMP 3.2.2 as its default editor, replacing the older GIMP 2.10 found in Mint 22.3.
