RELEASES

Bitcoin Protocol, Core, Knots, Security

Core Lightning v26.06rc2 — 2026-05-22
- Release candidate 2 for CLN 26.06. Documentation and gRPC interface refinements on top of rc1's graceful command, sendamount RPC, and BOLT12 payer-proof support. Routing-node operators should test on a non-production node before adopting.
Eclair 0.14.0 — 2026-05-21
- Significant Lightning release from ACINQ. Final versions of channel splicing, simple taproot channels, and zero-fee commitments all ship in this version. This is the Eclair side of the same protocol work showing up in CLN and LDK. If you run an Eclair routing node, this is the upgrade to track.

Hardware Signers and Hardware-Wallet Apps

Coldcard MK5 launch — 2026-05-29
- New flagship hardware. Larger Gorilla Glass screen, redesigned buttons, improved NFC, dual secure element architecture retained. Already supported in Bitcoin Safe 2.0.0rc0 from earlier this fortnight.
Frostsnap 0.3.0 — 2026-05-27
- Headline change: deterministic firmware build with cryptographic digest verification. So end users can independently verify the firmware binary matches the source. That is the right direction for any hardware signer carrying real money.
Keystone 3 v2.4.4 — 2026-05-26
- Wallet connection removal, Zcash SLIP39 support added, device verification fixes.
Trezor Suite v26.5.1 — 2026-05-27 (FTD re-surfacing)
- Adds ERC-681 QR code support in the send form. Show editorial: only relevant if you use Trezor for Ethereum-side workflows, not a Bitcoin-only change.
Ledger Live Desktop 4.5.0 — 2026-05-21
- Bridge integration refactoring across desktop and mobile.
Ledger Live Mobile 4.6.0 — 2026-05-28
- Async API updates and bridge resolution improvements.

Software Wallets

Sparrow Wallet 2.5.0 — 2026-05-21
- Headline feature: Silent Payments receiving wallets, including support for airgapped hardware wallet signers. Adds frigate.2140.dev as a Silent Payments capable public Electrum server, auto-selected when required. Plus a BIP32 derivation fallback when retrieving signing nodes for high-index inputs. This is the biggest privacy upgrade of the fortnight in any consumer-facing Bitcoin wallet, and the airgapped-signer support means Coldcard and similar users get it without going hot.
Sparrow Frigate 1.5.3 — 2026-05-30
- Adds a privacy-preserving hourly aggregate of historical scan stats, locally generated server.features response when the backend returns a method-not-found error, improvements to the hosts field in server.features.
Bitcoin Seed Tool 2.3.0 — 2026-05-19 (borderline, in grace)
- Educational interface redesign with violet accent color and integrated learning features.
