Stereum 2.6.0

How to Update

Stereum Launcher

  • Automatic Updates: Linux launchers will auto-update on startup as usual.
  • Update on MacOS: The Stereum Launcher is no longer signed. Download the dmg manually, install Stereum Launcher and try to open it. You will get a prompt. Do NOT move the app to trash, instead open System Settings > Privacy & Security, scroll to the security section, and click Open Anyway next to Stereum-Launcher. You then can open the Stereum Launcher normally.
  • Update on Windows: The Windows installer is no longer signed either. If Windows shows "Windows protected your PC", click More info > Run anyway.
  • From 2.6.0 on: On MacOS and Windows the launcher tells you about new versions and opens this release page, where you download and install it over the old one. Your settings are kept.
  • Manual Installation: Available via GitHub and stereum.com.

Stereum Node

  • Use the built-in Update Manager (available in the header bar) to apply updates safely and quickly.
  • Make sure to update your OS Packages as well from time to time 😉

⚠️ Glamsterdam on Hoodi: 26 October 2026, 17:42:48 UTC

Glamsterdam activates on Hoodi at epoch 132352. Every client of a Hoodi node must run a release that follows the fork, otherwise it stops following the chain. Stereum now shows an alert in the header with the clients that still need an update. Geth and Pluto have no release for the Hoodi fork yet.

After the fork, MEV-Boost is no longer used for block proposals. Validator clients ask relays and builders directly, configured per validator client with the new Builders icon inside a setup.

What's Changed

🏛️ Glamsterdam

  • ADD: Glamsterdam fork readiness alert with the minimum client release for each network by @NeoPlays in #2321
  • ADD: Builder settings per validator client (relays, block choice, minimum bid, max trusted payment), with a bid calculator, a live check whether relays serve ePBS and a takeover of the relays from MEV-Boost by @NeoPlays in #2321
  • UPDATE: Teku and Nimbus 26.10.1, Lodestar v1.50.0 and SSV v2.5.0 by default by @NeoPlays in #2321
  • UPDATE: Reth 2.8.0 and Charon 2.0.0-rc1 count as ready for Hoodi by @NeoPlays in #2323

Builder settings are saved with or without restarting the validator clients. Only clients whose settings change are restarted, and every step is listed in the task manager.

🔑 Staking page

  • CHANGE: Rebuilt staking page for thousands of keys, with aliases, search, filters and bulk settings for fee recipient, graffiti and gas limit by @NeoPlays in #2320
  • ADD: Import of local and remote keys with a live check, progress, slashing protection status and a result summary by @NeoPlays in #2320
  • ADD: Web3Signer slashing protection and Keys API databases run as Stereum services by @NeoPlays in #2320
  • FIX: Lodestar key removal, Lighthouse graffiti, Prysm exits and ports kept when switching clients by @NeoPlays in #2320

Existing Web3Signer database containers are migrated, and the slashing protection schema is upgraded before Web3Signer starts. Exits are blocked while the beacon node falls behind or where Prysm cannot sign them.

🤝 Distributed validators

  • FIX: Validator stats for Charon and Pluto setups, counted by the cluster's keys by @NeoPlays in #2319
  • FIX: Validator clients behind Charon or Pluto find their beacon node by @NeoPlays in #2319

🔌 Connection

  • FIX: No more connection storms after a network drop, which could get the launcher banned by fail2ban by @NeoPlays in #2316
  • FIX: About 60% less SSH load, and no more "Channel open failure" by @NeoPlays in #2319

When the connection drops, the launcher now retries with a growing delay and shows the next attempt in the reconnect dialog.

📊 Control page

  • FIX: Teku peer count, epoch and slot tooltips, and chart sizes by @NeoPlays in #2319

🚪 Lido ejector

  • FIX: Refresh the Lido oracle allowlist for mainnet and hoodi by @NeoPlays in #2317

Already delivered to nodes with the 2.5.2-patch node update.

🖥️ Launcher

  • UPDATE: MacOS and Windows open the release page for launcher updates by @NeoPlays in #2322
  • UPDATE: All dependencies upgraded, Tailwind 4, and no known audit vulnerabilities by @NeoPlays in #2318
  • CHORE: Windows builds are no longer code signed by @NeoPlays in #2319

Full Changelog: v2.5.2...v2.6.0
