![](https://images.hive.blog/p/C3TZR1g81UNaPs7vzNXHueW5ZM76DSHWEY7onmfLxcK2iPdiAa6tkfVRkpf9tvraQ9z55QS9fmMKbN32DMR4fCUEJKM2bGoquU7xeXZ7ZoKe6yrMrAtFTxA)

# Release Notes

The [BitShares](https://bitshares.org) Core software has been updated to the [5.0.0 Protocol Release](https://github.com/bitshares/bitshares-core/milestone/31?closed=1). The code name of the release is *"Splash"*. The Core software is used to build the validation nodes that perform consensus of all transactions on the BitShares blockchain. This release includes additions, improvements, and _changes to the consensus protocol_.

The scheduled protocol upgrade time is **`Monday, September 28, 2020 17:00:00 UTC` (`2020-09-28T17:00:00Z`)**.

Documentation for users may be be found at [How BitShares Works](https://how.bitshares.works).

Documentation for BitShares developers may be found at the [BitShares Developer Portal](https://dev.bitshares.works).

## <div id="who-should-upgrade-5-0-0"/> Who Should Upgrade?

**All node operators must upgrade** to handle the [protocol upgrade](#protocol-5-0-0).

## <div id="upgrade-process-5-0-0"/> Upgrade Process

### Precautions

- All validation nodes must complete their upgrade prior to **Protocol Activation**
- A _blockchain replay_ will automatically be performed after the validation node software is restarted. This typically takes a few hours on a modern CPU.

### <div id="upgrade-from-source-5-0-0" /> How to Upgrade from Source Code

**Note:**

* The code base requires a compiler that supports the C++ 14 standard
* The minimum supported boost version is 1.58, the maximum is 1.69.1
* The minimum supported CMake version is 3.2

#### Obtain the Source Code

The source code may be obtained by checking out the [5.0.0 tag](https://github.com/bitshares/bitshares-core/releases/tag/5.0.0).  Download the source at:

* [5.0.0.zip](https://github.com/bitshares/bitshares-core/archive/5.0.0.zip)
* [5.0.0.tar.gz](https://github.com/bitshares/bitshares-core/archive/5.0.0.tar.gz)


#### Build the Binaries

The binaries may be built by using your pre-existing process, or by following the standard instructions that can be found in the wiki:

* [Ubuntu](https://github.com/bitshares/bitshares-core/wiki/BUILD_UBUNTU)
* [macOS](https://github.com/bitshares/bitshares-core/wiki/Building-on-OS-X)
* [Windows](https://github.com/bitshares/bitshares-core/wiki/BUILD_WIN32)

#### Deploy the Binaries

Your standard process for deploying the node software may be used. No additional requirements or precautions will be required to deploy the new release.

### How to Upgrade with Docker

The latest Docker image may be found at [BitShares Core Docker page](https://hub.docker.com/r/bitshares/bitshares-core/) and updated with

```
docker pull bitshares/bitshares-core
```

# <div id="binaries-for-download-5-0-0"/> Binaries for download

Binaries of the command line interface (CLI) wallet and the node software are pre-built and available for download.

Note: These binary builds are reproducible and were signed using [Gitian](https://github.com/bitshares/bitshares-gitian). Please check the [README](https://github.com/bitshares/bitshares-gitian/blob/master/README.md) if you want to verify and/or contribute.
