A security maintenance release. No new features, and nothing about how the app works changes.
What this fixes
Updates the golang.org/x/crypto library to its current release, clearing 16 security advisories flagged against the previous version. These were all in the SSH portion of that library, which LAN Orangutan does not use (it only uses bcrypt to hash your password), so the app was never exploitable through them. The advisories applied to the whole module, so they are worth clearing.
The build also moves from Go 1.22, which has reached end of life, to Go 1.25, which the updated library requires.
Do you need to update?
There is no functional difference from v3.1.3. Updating is recommended so your install is built against the current, fully patched libraries, but nothing you rely on changes. Your config and device list are untouched.
