DigiByte Core v9.26.0-rc45 Release Notes

RC45 is a DigiDollar RC44 follow-up stabilization release candidate on the same public testnet26 chain.

Development branch: feature/digidollar-v1

Release: https://github.com/DigiByte-Core/digibyte/releases/tag/v9.26.0-rc45

Read This First

RC45 does not reset public DigiDollar testnet.

RC44 moved public testing to testnet26 and finalized the 35-slot oracle roster with a 7-signature MuSig2 quorum. RC45 keeps the same chain, same ports, same activation parameters, same 35 active oracle slots, and same v0x03 oracle bundle format while hardening final wallet recovery, operator key handling, OP_CHECKPRICE disablement, and DigiDollar health reconstruction before the next public rollout step.

Upgrade target:

• RC44 testnet26 nodes should upgrade to RC45.
• Do not wipe testnet26 just because of RC45.
• Do not return to testnet25; RC45 is still the RC44 public testnet chain.
• Existing oracle operators should keep their assigned testnet26 slot and key material unless separately coordinated.
• Back up wallets and oracle key material before upgrading.

What changed from RC44:

• DigiDollar wallet restore/rescan now recovers richer DD transaction history, including multi-output receives, DD change handling, and restored change classification.
• Local pending DigiDollar mints remain visible in the wallet UI/RPC instead of disappearing while they are still local or awaiting relay/confirmation.
• senddigidollar help and parsing were corrected so dual-unit help text cannot imply a 100x over-send.
• DigiDollar health reconstruction after startup was hardened and flushed before scans so restart state cannot poison consensus-health views.
• Residual RPC-cache consensus-health poisoning was fixed so RPC-facing health cache data cannot disagree with consensus state.
• OP_CHECKPRICE is deterministically disabled and the remaining dead price-hook surface was removed from init/docs/operator guidance.
• Oracle operators now have explicit oracle key export/import RPC support for safer wallet migration and recovery.
• Multi-oracle end-to-end coverage now detects already-mined MuSig2 bundles instead of masking restore/history failures.
• Operator, activation, wallet-integration, OP_CHECKPRICE, architecture, and roster documentation were aligned with the RC45 behavior.

What did not change:

• Testnet name remains testnet26.
• Data directory remains testnet26.
• Testnet P2P port remains 12033.
• Default testnet RPC port remains 14026.
• DigiDollar activation remains BIP9 bit 23, minimum height 600.
• Oracle roster remains 35 active slots, IDs 0 through 34.
• Oracle quorum remains 7 signatures from the configured 35-key MuSig2 roster.
• Oracle bundle format remains v0x03.
• Mainnet activation status does not change.
• DigiDollar economic rules, ERR policy, DCA policy, address formats, and wallet database format do not change.

Summary

RC45 is the final RC44 hardening pass for wallet recovery, oracle operator key operations, and consensus-health correctness.

The release focuses on failure modes that matter before broader public testing: restored wallets must show the same DigiDollar history after rescans, local pending mints must remain visible to users, health state must reconstruct deterministically after restart, OP_CHECKPRICE must stay fully disabled, and oracle operators need a supported export/import path for oracle key migration instead of fragile manual wallet handling.

RC45 is not a network reset and not an economic redesign.

One-Line Fix Summary

• Wallet rescan: restored DigiDollar change history now comes back correctly after rescans.
• Multi-output receives: wallet restore now reconstructs DD receive history across multi-output transactions.
• Sender-side change: restored DD change is kept out of receive history so send rows stay semantically correct.
• Pending mints: local pending DigiDollar mints remain visible instead of vanishing while still pending.
• senddigidollar help: dual-unit help text now avoids the old 100x over-send ambiguity.
• Startup health: DigiDollar system-health reconstruction is flushed before wallet/state scans.
• Consensus health: RPC cache data can no longer poison residual consensus-health views.
• OP_CHECKPRICE: disabled deterministically and documented as disabled; dead price-hook init surface removed.
• Oracle key migration: added RPC support to export/import oracle keys for safer operator recovery.
• E2E coverage: multi-oracle tests now detect existing MuSig2 bundles and stop masking restore failures.
• Operator docs: oracle setup, activation, wallet integration, OP_CHECKPRICE, and roster docs were refreshed for RC45.

Testnet26 Network Details

Older operator notes that mention testnet25, port 12032, incomplete oracle placeholders, or OP_CHECKPRICE mock-price behavior are stale for RC45. Use the values above.

Minimum RC45 operator checklist:

1. Back up wallets and oracle key material.
2. Install/run RC45.
3. Keep using -testnet and the existing testnet26 datadir.
4. Keep P2P port 12033 open and advertised.
5. Confirm getblockchaininfo reports the testnet26 genesis hash above.
6. Confirm getoracles shows active oracle IDs 0 through 34.
7. If migrating an oracle wallet/key, use the new oracle key export/import RPC flow instead of manually copying partial wallet state.
8. Confirm local DigiDollar pending/history state survives restart/rescan before reporting operator readiness.

Validation Status

RC45 code validation completed on June 13, 2026 from feature/digidollar-v1 at code commit 5a7b1e90623fb5d76e222c9cf58287dd2b1b3642. Later release-note-only commits do not change consensus, wallet, RPC, Qt, or test behavior.
