DigiByte Core v9.26.0-rc42 Release Notes

RC42 is a DigiDollar RC41 follow-up bug-fix, wallet/RPC hardening, Qt usability/visual-QA, oracle-doc, and DGBstats release candidate on the same public testnet25 chain.

Development branch: feature/digidollar-v1

Release: https://github.com/DigiByte-Core/digibyte/releases/tag/v9.26.0-rc42

Read This First

RC42 does not reset public DigiDollar testnet.

RC41 moved public testing to testnet25. RC42 keeps that same network, same genesis, same ports, same activation heights, same 35-slot oracle roster capacity, and same oracle bundle format. Operators upgrading from RC41 should upgrade binaries and keep using their existing testnet25 data unless they are intentionally starting a fresh node.

Upgrade target:

• RC41 testnet25 nodes should upgrade to RC42.
• Do not wipe testnet25 just because of RC42.
• Do not return to testnet24; RC42 is still the RC41 public testnet chain.
• Existing oracle operators should keep their assigned RC41/testnet25 slot and key material unless separately coordinated; RC42 adds digibyte-maxi at testnet slot 17.

What changed from RC41:

• Wallet/RPC mint and redeem relay handling was hardened.
• Fragmented UTXO mint consolidation was completed.
• DigiDollar Qt send/status/redeem/double-click workflows were fixed.
• Qt tooltip and DigiDollar modal styling were visually QAed and corrected.
• Tier-0/minimum-mint user feedback and validation were clarified.
• DGBstats oracle/testnet25 copy and fractional difficulty display were fixed.
• The local multi-oracle testnet harness was kept runnable with live price movement.
• Testnet oracle slot 17 was assigned to active operator digibyte-maxi without changing the 9-signature oracle quorum.

What did not change:

• Testnet name remains testnet25.
• Testnet P2P port remains 12032.
• Default testnet RPC port remains 14026.
• DigiDollar testnet activation height remains 600.
• Oracle testnet activation height remains 600.
• Oracle epoch length remains 40 blocks.
• 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

RC42 closes the RC41 issue-validation pass.

It fixes confirmed RC41 regressions in DigiDollar wallet/RPC commit ordering, fragmented mint consolidation, Qt status refresh, locked-wallet redeem state, dark-mode/readability styling, DigiDollar transaction details, DigiDollar modal theming, minimum mint copy, tier-0 validation, and DGBstats testnet/oracle displays.

RC42 is not an economic redesign and not a new testnet reset.

One-Line Fix Summary

• Pending mint/change visibility: added regression coverage proving mint DGB change remains wallet-owned/spendable and pending DigiDollar state remains visible.
• Mint wallet relay: fixed duplicate broadcast-before-wallet-commit so RPC/Qt mints commit through the wallet relay path once and avoid !wtx.InMempool().
• Fragmented UTXO minting: fixed auto-consolidation to run enough passes and retry minting from usable consolidation outputs.
• DigiDollar send/status refresh: moved slow refresh paths off the blocking UI path and added explicit DigiDollar update signals.
• Startup position validation: kept the expected pre-chainstate readiness warning harmless and added retry validation once chainstate is ready.
• Redeem locked-wallet state: refreshed redeem UI on wallet lock/unlock and clarified when a redeemable vault still cannot sign.
• Dark-mode tooltips: normalized native and custom tooltip rendering so dark-mode tooltips are readable across normal wallet and DigiDollar views.
• Shutdown dialog contrast: added explicit dark-mode shutdown dialog styling.
• DigiDollar Send Total DD contrast: fixed dark-mode label/value contrast for the Total DD row.
• Literal <qt> tooltip tags: stripped Qt rich-text envelopes before custom tooltip escaping so wrapped tooltips no longer show raw tags.
• Minimum mint amount copy: below-minimum mint feedback now reports the actual configured chain minimum.
• Tier-0 / 1-hour mint clarity: accepted tier 0 in wallet validation and separated lock duration from effective redeem availability in user copy.
• DGBstats testnet difficulties: fixed fractional testnet algo difficulty rendering and Core algo-name normalization.
• DGBstats oracle onboarding: updated oracle/testnet25 copy to six active exchanges, v0x03-only bundles, 60-second exchange fetch/broadcast, and assigned-slot coordination.
• DigiDollar Overview double-click: double-clicking a recent DigiDollar transaction now switches to DD Transactions and focuses the matching row.
• DigiDollar Transactions double-click: double-clicking a DD transaction now opens a DigiDollar details window like normal DGB transactions.
• DigiDollar transaction details theme: DD transaction details use green DigiDollar styling in light and dark mode instead of normal DGB blue.
• DigiDollar modal dialogs: DD coin selection, payment request, and address book dialogs now force green DigiDollar light/dark styling.
• DigiDollar Send note field: renamed the misleading local Label field to local Note and updated tooltip/copy.
• Rapid batch mint state: clarified local/stempool/mempool/rejected/confirmed DigiDollar history states and added lock-tier reject context.
• Redeem wallet relay: fixed RPC redeem to commit through wallet relay once and make rapid duplicate redeems fail cleanly.
• Owner-key guard test: corrected the source guard that proves DigiDollar owner keys are stored before wallet-owned commit.
• Multi-oracle harness: kept test_multi_oracle_testnet.sh runnable end to end while live DGB price moved.
• Testnet oracle slot 17: added active operator digibyte-maxi with pubkey 03649d750bcad5b42b3dd0f11c8d98d62ed5afd515cd986663f81c35f086e58d47; testnet active roster is now 18 keys and quorum remains 9 signatures.
• RC41 ledger: documented final validation status, test evidence, visual QA evidence, and commit hashes for all 18 tracked issues.

Testnet25 Network Details

Older operator notes that mention testnet24 or P2P port 12031 are stale for RC42. Use the values above.

RC42 also activates testnet slot 17 for digibyte-maxi. This adds the slot-17 x-only key to consensus.vOraclePublicKeys, raises the testnet active key count to 18, marks the slot active in vOracleNodes, and keeps the oracle quorum at 9 signatures.

Minimum RC42 operator checklist:

1. Back up wallets and oracle key material.
2. Install/run RC42.
3. Keep using -testnet and the existing testnet25 datadir.
4. Keep P2P port 12032 open and advertised.
5. Confirm getblockchaininfo reports the testnet25 genesis chain.
6. Confirm getoracles shows the expected 35-slot roster, with active configured operators online and reserve slots inactive.
7. Confirm assigned oracle slot/key material still matches the RC42/testnet25 chainparams roster.

Validation Status

Focused RC42 validation completed on May 26, 2026 from feature/digidollar-v1.

Important validation notes:

• The final multi-oracle run used live market data and passed all DigiDollar mint, redeem, transfer, persistence, reindex, restore, and oracle checks with 18 active local oracles and 9-of-35 consensus; live oracle consensus price during the run was about $0.00356/DGB.
• The final multi-oracle script log was /tmp/digidollar_debug_logs/test_run_20260526_172022.log.
• The functional suite reported environment-gated skips only and warned that feature_assumeutxo.py and feature_assumevalid.py are not in the configured test list.
• A final tagged-head functional run with explicit --jobs=$(nproc) passed in 190 seconds runtime / 4507 seconds accumulated runtime.
• DGBstats Playwright E2E remained red independently of the RC42 fixes, with broad loading-state, mocked-data, touch-target, browser-matrix, and route-specific expectations failing in this environment.

Qt Visual QA

RC42 included automated offscreen Qt tests and X11 visual QA for the affected wallet surfaces.

Notes For Testers

Please focus RC42 testing on:

• Upgrading RC41 nodes without wiping testnet25.
• Rapid mint and redeem attempts from RPC and Qt.
• Fragmented UTXO minting and consolidation.
• DigiDollar send/status refresh while the wallet is busy.
• Redeem screens when a vault is redeemable but the encrypted wallet is locked.
• Tooltips in light and dark mode across normal DGB pages and DigiDollar pages.
• DD Overview recent transaction double-click navigation.
• DD Transactions double-click details in light and dark mode.
• DigiDollar coin selection, payment request, and address book dialogs in light and dark mode.
• Tier-0 / 1-hour mint confirmation copy and effective unlock expectations.
• DGBstats testnet difficulty display and oracle/testnet25 operator copy.

Oracle operators should keep using testnet25, P2P port 12032, and their assigned RC42/testnet25 slots.

Known Risks

• RC42 does not include mainnet activation. Mainnet launch still requires the explicit release and activation decision.
• Mainnet reserve oracle slots remain placeholders until operators provide mainnet oracle keys and a later release adds those keys to chainparams.
• If fewer than 9 valid active oracle operators are online and fresh, new oracle bundles should fail closed.
• DGBstats Playwright E2E remains red independently of the RC42 fixes; the DGBstats changes in this pass are covered by passing Vitest tests and production build.

Bottom Line

RC42 is the RC41 stabilization release candidate for the same public testnet25.

It keeps the testnet and DigiDollar economics unchanged, fixes the validated RC41 wallet/RPC and Qt issues, completes the requested visual QA cleanup, updates DGBstats/operator copy, and leaves the network ready for continued testnet25 validation.
