Fork/Reset testnet at block 4001
--------------------------------
There was a critical bug discovered in Bitcoin Core's codebase recently which
can cause node receiving a block to crash https://github.com/bitcoin/bitcoin/pull/14247
This release is NOT required on mainnet. It is intended to be deployed on testnet and will cause a fork at block 4001.
The plan is to restart all testing for the v0.13.0.0 upgrade process.
0.12.3.3 Change log
When deployed on testnet, it is required to start with a fresh data directory or call Dash Core with `-reindex-chainstate`.
0.12.3.4 Change log
===================
See detailed [set of changes](https://github.com/dashpay/dash/compare/v0.12.3.2...dashpay:v0.12.3.3).

Dash Core version 0.12.3.3
==========================
Release is now available from:
<https://www.dash.org/downloads/#wallets>
This is a critical bugfix release.
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](release-notes/dash/release-notes-0.12.2.2.md#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, 0.12.3.1/2
Downgrading to these versions does not require any additional actions, should be
fully compatible.
