Bitcoin Core 28.3 guide covering lower relay fees, TRUC reorganisation handling, onion whitelist permissions, build fixes and controlled deployment.
This guide explains Bitcoin Core 28.3 release in plain English. It summarises the important changes, who they affect and what should be checked before an upgrade.
Bitcoin Core 28.3 release: The default block minimum is 1 satoshi per kvB, while minimum relay and incremental relay defaults are 100 satoshis per kvB.
A node operator is checking Bitcoin Core 28.3 release. Express units explicitly and inspect effective configuration after restart. Measure peer propagation and confirmation outcomes before offering a service guarantee.
The default block minimum is 1 satoshi per kvB, while minimum relay and incremental relay defaults are 100 satoshis per kvB. Express units explicitly and inspect effective configuration after restart.
Wallet fee selection and dust policy are separate controls. Do not infer spendability, economical confirmation or dust acceptance solely from the lower node defaults.
A transaction accepted locally at a low feerate may not travel across peers running different policy. Measure peer propagation and confirmation outcomes before offering a service guarantee.
TRUC policy checks are not applied while transactions are restored during a reorganisation. Test mempool transitions and downstream alerts with controlled reorg scenarios.
Inbound onion connections regain configured whitelist permissions. Audit whitelist scope and confirm that permissions are neither missing nor broader than intended.
Build, test and documentation fixes improve branch reliability without importing the complete Core 29 or 30 feature set. Maintain an explicit branch-compatibility matrix.
Node operators test the release on a representative non-production system. They check startup, normal operation, failure handling and restart before changing a live node. Connected wallets, monitoring and mining services should also be checked.

Bitcoin Core 28.3 is a maintenance release with visible relay and network effects. Operators should verify effective policy locally, test behaviour across real peers and keep the older branch artefact available until the rollout is proven.
Check the current specification status and the documentation for the exact implementation you operate before moving production funds or changing a mining node.
Bitcoin Core 29.4 guide covering repeated chainstate rewrites, regular compaction, LevelDB seek compaction, transaction-data lifetime and wallet sizing fixes.
Bitcoin Core 31.1 guide covering the private-broadcast IP leak fix, proxy reconnections, chainstate compaction, BDB migration and settings-write safety.
Bitcoin Core 30.3 guide covering excessive chainstate I/O, regular compaction, wallet bump and coin-selection fixes, PSBT, MuSig2 and build maintenance.
