[!IMPORTANT] Hoodi node operators must upgrade before Mon, 26 Oct 2026, 17:42:48 UTC. This release removes the Glamsterdam fork from Hoodi. A Hoodi node still on 2.2.0 will activate Glamsterdam at that time and fork off the network. Your consensus client must also be on a release that removes the Glamsterdam fork from Hoodi.

Release notes

A patch release on top of 2.2.0 that removes the Glamsterdam (Amsterdam) fork from Hoodi, which was planned for Mon, 26 Oct 2026, 17:42:48 UTC (timestamp 1793036568).

The fork is on hold on Hoodi following the security concerns discussed on ACDE [#248]. A new date will come in a later release.

This is the only change. There are no database-format or configuration changes, so you can upgrade in place from any 2.2.x version. No other network is affected.
