# Dash Core version v21.1.0 This is a new minor version release, bringing important bugfixes. This release is **mandatory** for all masternodes. This release is optional but recommended for all other nodes. Please report bugs using the issue tracker at GitHub: # 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](https://www.dash.org/forum/index.php?threads/ehf-activation-issues.55146/) 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. # v21.1.0 Change log See detailed [set of changes][set-of-changes]. # Credits Thanks to everyone who directly contributed to this release: - Konstantin Akimov - PastaPastaPasta - UdjinM6 - ogabrielides As well as everyone that submitted issues, reviewed pull requests and helped debug the release candidates. # Older releases These release are considered obsolete.
