+- `komodo` has been updated to the v2 release line (2.x). See the [upstream v1 → v2 upgrade guide](https://github.com/moghtech/komodo/releases/tag/v2.0.0).
+
 - `boot.loader.systemd-boot` gained support for [Automatic Boot Assessment](https://systemd.io/AUTOMATIC_BOOT_ASSESSMENT/) via the new [`boot.loader.systemd-boot.bootCounting`](#opt-boot.loader.systemd-boot.bootCounting.enable) options, allowing automatic detection of and recovery from bad NixOS generations. As part of this change, boot loader entries on the ESP/XBOOTLDR partition are now named `nixos-<content-hash>.conf` instead of `nixos-generation-<n>.conf`; existing entries are migrated automatically on the next `nixos-rebuild boot`/`switch`.
 
 - The `newuidmap` and `newgidmap` security wrappers are now installed with `cap_setuid`/`cap_setgid` file capabilities instead of the setuid-root bit, matching shadow's `--with-fcaps` install mode and other major distributions. Rootless containers (podman, docker-rootless, unprivileged user namespaces) are unaffected. The only behavioural change is that mapping host uid 0 via `/etc/subuid` (which NixOS never configures by default) additionally requires `cap_setfcap`; users who explicitly grant uid 0 in a subuid range can restore the previous behaviour with `security.wrappers.newuidmap.capabilities = lib.mkForce "cap_setuid,cap_setfcap+ep";`.
