Raw Blame History

Dash Core version 0.12.3.2

Release is now available from:

https://www.dash.org/downloads/#wallets

This is a new minor version release, bringing various bugfixes and other improvements.

Please report bugs using the issue tracker at github:

https://github.com/dashpay/dash/issues

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 < 0.12.2.2

Because release 0.12.2.2 included the per-UTXO fix which changed the structure of the internal database, you will have to reindex the database if you decide to use any pre-0.12.2.2 version.

Wallet forward or backward compatibility was not affected.

Downgrade to 0.12.2.2/3, 0.12.3.1

Downgrading to these versions does not require any additional actions, should be fully compatible.

Notable changes

Improve initial sync

Some users had problems getting their nodes synced. The issue occured due to nodes trying to get additional data from each available peer but not being able to process this data fast enough. This was recognized as a stalled sync process and thus the process was reset. To address the issue we limited sync process to 3 peers max now and the issue should no longer appear as long as there are at least 4 connections.

Testnet/Devnet fixes

Turned out that a low-diff rule for slow blocks backported from Bitcoin works a bit too aggressive for a blockchain which uses a dynamic per-block difficulty adjustment algorithm (DGW). While blocks are still produced at a more or less constant rate on average, the rate however is way too high.

We also lifted multiple ports restriction on devnet and also incuded other fixes which should improve connectivity on devnets which are using nodes with multiple different ports.
