v4.0.1

Optional Upgrade

• Fixes an edge-case bug where masternodes silently lose the ability to mine blocks. This affects miners only if the first key in defi.conf for masternodes is an invalid or outdated key that doesn't represent an enabled state. This bug causes the miners to silently fail mining a block even if there are other valid keys.

Upgrade Notes

• From v4.0.0 (prev. latest stable): drop in-upgrade.
• Older nodes, require a fresh sync or bootstrap from snapshots.
• From pre-releases (v4-rc, v4-beta, etc): -reindex or fresh required or bootstrap from snapshots required.
• For nodes that are being restored from recent snapshot, as with all updates before: -rescan for the wallet txs and additionally -spv_resync for users who hold BTC. If either isn't used, they may not be shown in the wallet until rescanned/resynced.
• defid now requires glibc 2.29 or greater to run. You may need to update your OS if you are running an older version. (Ubuntu 18, Debian 10, etc.)
