Version 0.21.5.8
The maintainers describe this as a maintenance release affecting MWEB validation, transaction relay, mining and resource handling. They strongly recommend upgrading, particularly for miners, pools, exchanges and MWEB service operators. It also includes the changes from 0.21.5.7, which was distributed to mining pools rather than published as a general release.
| Your role | What to check |
|---|---|
| Core wallet user | Read the release notes, keep a verified backup and authenticate the installation files. Updating Core does not update a separate mobile wallet. |
| Node or MWEB service operator | Review validation and relay changes, plan the update and check synchronization and service behavior afterwards. |
| Miner or pool operator | Review consensus activation height 3,172,640 and block-template changes in the official notice. Compare against the current verified chain height; this is not a calendar-date deadline. |
| Exchange customer | You cannot update the exchange's node. Check the service's own deposit and withdrawal notices. |
