| 1 | +# Dash Core version v21.1.0 |
| 2 | + |
| 3 | +This is a new minor version release, bringing important bugfixes. |
| 4 | + |
| 5 | +This release is **mandatory** for all masternodes. |
| 6 | +This release is optional but recommended for all other nodes. |
| 7 | + |
| 8 | +Please report bugs using the issue tracker at GitHub: |

| 13 | +# Upgrading and downgrading |
| 14 | + |
| 15 | +## How to Upgrade |
| 16 | + |
| 17 | +If you are running an older version, shut it down. Wait until it has completely |
| 18 | +shut down (which might take a few minutes for older versions), then run the |
| 19 | +installer (on Windows) or just copy over /Applications/Dash-Qt (on Mac) or |
| 20 | +dashd/dash-qt (on Linux). |
| 21 | + |
| 22 | +## Downgrade warning |
| 23 | + |
| 24 | +### Downgrade to a version < v21.0.0 |
| 25 | + |
| 26 | +Downgrading to a version older than v21.0.0 may not be supported due to changes |
| 27 | +if you are using descriptor wallets. |
| 28 | + |
| 29 | +### Downgrade to a version < v19.2.0 |
| 30 | + |
| 31 | +Downgrading to a version older than v19.2.0 is not supported due to changes |
| 32 | +in the evodb database. If you need to use an older version, you must either |
| 33 | +reindex or re-sync the whole chain. |
| 34 | + |
| 35 | +# Notable changes |
| 36 | + |
| 37 | +Allow EHF Resigning |
| 38 | +------------------- |
| 39 | + |
| 40 | +During implementation, the values for requestID and msgHash for EHF signing were switched. As a result, a masternode |
| 41 | +which participated in an earlier failed attempt to form an EHF message is unable to participate in subsequent |
| 42 | +attempts. This is because the LLMQ Signing System requires that the requestID be unique, and that a node will not |
| 43 | +sign two different msgHash for the same requestID. See the [forum post](https://www.dash.org/forum/index.php?threads/ehf-activation-issues.55146/) |
| 44 | +explaining it further. |
| 45 | + |
| 46 | +As there is no need to restrict double signing for EHF, we now allow signing of multiple msgHash's for a single EHF |
| 47 | +requestID. Once a sufficient number of masternodes upgrade to v21.1, the EHF message will be automatically signed and |
| 48 | +mined. |
