Node operators — the fleet moved to a new build on 2026-09-19. A node started from today's main prints params fingerprint c3a5e91d… and this fence schedule: 1150, 1900, 2150, 2400, 3500, 4000, 6900, 7100, 7101, 7200, 7301. If your node prints anything else — 060e3597… and a schedule ending 6900, 7000 is the build this notice used to describe — it is the older one.

What is still ahead, and the one height to act before. Everything at or below 6,900 is identical in both builds, so the two interoperate today. They part at DAA 7,000: only the OLDER build schedules a fence there, and from that height it judges blocks by a rule the new build does not apply until 7,100. Upgrade before 7,000 or your node will follow a chain the fleet is not on. After that, 7,101 arms the PALW upgrade bundle (execution lane, panel economy, DNS stake gate, model registry) and 7,200 verification V2.

Keep your appdir — the genesis did not move. Rebuild from main; details in docs/testnet11-6701-upgrade-announcement.md.
