OpenSO Launcher 0.4.4

Linux

Ships as an AppImage. Self-update understands AppImage installs and replaces the single file atomically, rather than trying to swap a directory that isn't there.
The embedded AppImage runtime is pinned and hash-verified, and is the static build — no libfuse2 required on the host.
Hardened Linux archive extraction, including preserving the executable bit through a self-update.

Detects an existing TSO install — launcher-managed, registry, or a legacy retail path — and validates that it is actually complete rather than trusting a bare folder.
A partial or truncated install is reported as Incomplete with what's missing, and offers a repair.
Reinstall now always downloads a fresh, verified copy. It previously reused another install found on your machine without saying so, which — because the source comes from the Maxis registry — could be an unrelated server's game files.
Reusing a local copy is still supported, but as a deliberate "Use existing copy" action that names the folder it would copy from, offered only when nothing is installed yet. It saves the 1.27 GB download on a fresh setup.

Fixed: updating could loop forever when a second launcher window was open. A background instance kept the launcher's files locked, the update silently failed, and the old version relaunched and tried again endlessly. The launcher is now single-instance, and the updater retries a blocked copy for up to 30 seconds instead of failing silently. (This fix is why 0.4.3 was pulled.)
Fixed: the launcher could not update on accounts with non-Latin usernames. Greek, Cyrillic, CJK and similar profile names were mangled into garbage in the update script, and the update failed with "the launcher cannot be found at the path specified".
No more console window during an update. A command window used to flash — and could be left stranded on screen showing an error.

New: DAILY PAYOUTS on the home page. Each money object's payout rate for today, its movement since yesterday, and the day's bonus object — with the objects' catalog sprites. Appears automatically once the game server is running v0.4.3 or later (the rates come from its new public payouts API); against an older server the launcher simply doesn't show the section.
The city map is legible. Genesis' map thumbnail never appeared at all, because the shard runs one of the original TSO maps and the launcher only looked among the OpenSO-bundled ones. It's now shown at its natural size instead of being blown up sevenfold into a blur, and sits beside the live server stats under the shard name.
The 3D Mesh Pack row on the Installer page showed the literal text "True" instead of its install state, and its button now reads Reinstall once the pack is present.
