Mesa preflight: post-hard-fork banner and bump to 4.0.0-preflight-3f038cb#1193
Conversation
The Mesa preflight network hard-forked at 2026-04-27 14:00 UTC. The post-fork chain runs the Mesa release 4.0.0-preflight-3f038cb, which raises the transaction protocol version to 5.0.0 — a breaking wire-format change that retires every pre-fork build, including the stop-slot release 4.0.0-preflight-stop-2967b39. Update the network-upgrades index, preflight-network, and archive-upgrade pages to reflect the post-fork state: warning banners now describe the hard fork as completed rather than upcoming, the preflight build matrix is rewritten around 4.0.0-preflight-3f038cb (with prior builds demoted to a historical list), and every Docker tag, Debian package pin, and inline command is bumped accordingly. Also regenerate static/llms-full.txt. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…bility The Mesa preflight hard fork occurred at 13:00 UTC, not 14:00 UTC. Correct every timestamp on the network-upgrades index, preflight-network, and archive-upgrade pages. Also document the matching SDK release: zkApp developers must use o1js@3.0.0-mesa.698ca, the first o1js version that targets transaction protocol v5.0.0. Earlier o1js releases produce transactions that the post-fork chain will reject. Add this guidance to the post-fork banners on the index and preflight-network pages, and list o1js@3.0.0-mesa.698ca alongside the daemon build matrix on preflight-network. Regenerate static/llms-full.txt to match. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
