Linux CLI Suite (Debian/Ubuntu)

Install ant, antnode, and antctl using the signed deb package.

Download the appropriate deb file for your architecture:

• x86_64 (AMD64): 2026.2.1.1.autonomi.x86_64-unknown-linux-musl.deb
• ARM64 (aarch64): 2026.2.1.1.autonomi.aarch64-unknown-linux-musl.deb
• ARMv7 (armhf): 2026.2.1.1.autonomi.armv7-unknown-linux-musleabihf.deb
• ARM (armel): 2026.2.1.1.autonomi.arm-unknown-linux-musleabi.deb

Import and trust the GPG signing key (first time only):

curl -fsSL https://raw.githubusercontent.com/maidsafe/autonomi/main/resources/keys/autonomi-signing-key.asc -o /tmp/autonomi-signing-key.asc
gpg --import /tmp/autonomi-signing-key.asc
echo 'D39ABED4DC364A8D0812F539C19B57B73D6EA0AB:6:' | gpg --import-ownertrust

Verify the signature:

gpg --verify 2026.2.1.1.autonomi.x86_64-unknown-linux-musl.deb.asc 2026.2.1.1.autonomi.x86_64-unknown-linux-musl.deb

Install the package:

sudo dpkg -i 2026.2.1.1.autonomi.x86_64-unknown-linux-musl.deb

Detailed Changes

Network

Added

• Version-based peer rejection system that enforces minimum node version requirements during the
  identify protocol exchange. Nodes running versions below the minimum are disconnected.
• New metrics for version gating: version_check_result (tracking accepted, rejected, legacy, and
  parse error outcomes) and peer_type (tracking node, client, and unknown peer types).

Changed

• Trust-based replication scoring has been re-enabled, allowing nodes to factor peer trust scores
  into replication decisions.
• The minimum required node version has been set to 0.4.14.

Payments

Changed

• Merkle payment calldata has been compacted by packing data type and total cost unit into a single
  U256 value. This reduces on-chain transaction size and gas costs for merkle batch payments.

API

Added

• MerkleBatchPaymentComplete client event, emitted after each merkle tree batch payment completes.
  This enables progressive saving of receipts to disk for upload resume support.
• RegularBatchPaymentComplete client event, emitted after each regular batch payment completes,
  providing the same progressive saving capability for non-merkle uploads.
• MerklePaymentReceipt::add_already_existed method to record chunks that were found to already
  exist on the network, avoiding redundant network queries on upload resume.
• already_existed field on MerklePaymentReceipt to persist the set of chunks known to exist on
  the network across upload resume attempts.

Changed

• Merkle upload resume now skips network existence checks for chunks that are already known to exist
  or have been previously paid for, reducing unnecessary network queries.
• Stream batch size and upload concurrency are now configured independently in merkle uploads. Stream
  batch size uses UPLOAD_FLOW_BATCH_SIZE while upload concurrency uses CHUNK_UPLOAD_BATCH_SIZE.

Fixed

• Chunks that already existed on the network are no longer re-quoted during upload resume,
  preventing unnecessary payment attempts.

Ant Client

Added

• The file upload command now displays the network address for private uploads alongside the
  private address.

Changed

• Payment receipts are now progressively saved to disk during uploads for both merkle and regular
  payment modes. This improves upload resume reliability by preserving payment state as batches
  complete rather than only on failure.
• Cached payment receipt files are now cleaned up before saving a new receipt, preventing stale
  files with different timestamp prefixes from accumulating.
