Dijkstra hard fork stays undated as node 11.2 advances

The Dijkstra hard fork remains undated after the October 27, 2026 minutes of Intersect's Hard Fork Working Group, which treat node 11.2 as the build for the era's feature set apart from Leios and leave the Cardano (ADA) mainnet epoch unstated. Filecoin's Solstice upgrade went live at epoch 6,470,279, the kind of marker these minutes leave out.

The written summary says the 11.2 release "is imminent and is expected to become available today or tomorrow", and that once it is available it "will be used to fork DijkstraNet into the Dijkstra era". The group expects "some version of 11.2, be it 11.2 or 11.2.1, 11.2.2, etc, become mainnet ready", and it says stake pool operators (SPOs) need to update the node version prior to the hard fork. Jeff, Amani and Sam held the 11.2 agenda item, and Sebastian held node 11.3. Tag 11.2.0 was created on October 27, 2026 and published on October 28, 2026, with GitHub flagging the release as a pre-release.

Published notes call 11.2.0 "a pre-release version of cardano-node that is not yet recommended for use on mainnet", so the package that followed the call is the early build, and the mainnet-ready patch the minutes describe is a later step on the same line. The tracking ticket, cardano-node issue 6672, was opened on September 1, 2026 by GitHub user koslambrou and closed on October 30, 2026, with node pull request 6677 and the other listed components marked released.

What 11.2.0 changes for operators

Shipped network configuration files now use an envelope that "cannot be read by nodes older than 11.2", while flat configurations still load on 11.2.0, after the move to the cardano-config library. Node-to-client versions older than NodeToClientV_23 drop out of 11.2.0, so wallets, indexers and other downstream tools need libraries that speak NodeToClientV_23, which the notes trace to node 10.7.0. The minutes ask those teams to integrate against 11.2 on DijkstraNet as soon as the package is available.

Where Leios and node 11.3 sit

The summary states that this version "includes the full feature set of Dijkstra era hard fork scope except Leios". The 11.2.0 notes use a narrower description, citing continued Dijkstra-era work plus "Groundwork for Leios and Peras (off by default)". An updated Leios impact assessment has gone from the Technical Steering Committee back to its authors, and Bosko is to merge it onto the Ouroboros Linear Leios page.

Node 11.3, Sebastian's item, includes Cardano Improvement Proposal 23 (CIP-23), Fair Min Fees. Counted from the October 27 meeting, the summary places that version at least two weeks out, and on a realistic path three to four weeks from a tagged pre-release. Downstream teams are asked to integrate against an 11.3 prototype on Musashi Dojo, and SanchoNet is expected to follow the other Cardano testnets into the Dijkstra era as a community-owned network. Plutus v4 cost models have two routes, hardcoding into the genesis file or a protocol-parameter-update governance action before the fork, which the minutes prefer and say would need submission as soon as possible.

Client dates beside an open fork slot

Amaru's update, supplied before the meeting by team representative Damien, says the client had been producing empty blocks for five days on version 10.11.20261022^beta, with a mainnet block producer planned for November 5, 2026. The Amaru team is organizing a node-diversity workshop on November 12 and 13, 2026 at the London Marriott Hotel Canary Wharf. November dates on that list belong to client diversity, and the Dijkstra mainnet hard-fork slot stays unstated beside them.

The Dijkstra risk log now has an owner on each item, scores of 50 and above were marked down where mitigations had worked, and Bosko still owes a formal-assessment column. Carlos is to circulate a shorter constitution presentation after the guardrails call on the previous Friday, October 23, 2026, with parameters in the constitutional amendment portal. Ian and Larisa are to prepare readiness communications once 11.2 is released, with limited integration expected against the 11.3 prototype, and the group keeps meeting weekly until the work needs tighter alignment.

What comes next is a stack of documents rather than a date. A later 11.2 patch is the build the working group expects to call mainnet-ready. On the digital-assets desk, Hedera's Network MCP remains on testnet beside a live mainnet build, and IoTeX's Zanzibar hard fork pays voter rewards on chain. Until Intersect publishes a hard-fork slot of its own, the Dijkstra era is a release sequence with the mainnet question left open.
