Upgrading and downgrading

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Dash-Qt (on Mac) or dashd/dash-qt (on Linux).

Downgrade warning

Downgrade to a version < v21.0.0

Downgrading to a version older than v21.0.0 may not be supported due to changes if you are using descriptor wallets.

Downgrade to a version < v19.2.0

Downgrading to a version older than v19.2.0 is not supported due to changes in the evodb database. If you need to use an older version, you must either reindex or re-sync the whole chain.

Notable changes

Allow EHF Resigning

During implementation, the values for requestID and msgHash for EHF signing were switched. As a result, a masternode which participated in an earlier failed attempt to form an EHF message is unable to participate in subsequent attempts. This is because the LLMQ Signing System requires that the requestID be unique, and that a node will not sign two different msgHash for the same requestID. See the forum post explaining it further.

As there is no need to restrict double signing for EHF, we now allow signing of multiple msgHash's for a single EHF requestID. Once a sufficient number of masternodes upgrade to v21.1, the EHF message will be automatically signed and mined.
