+Embark 5.1
+===
+
+## Interfaces & Libraries Configuration
+
+Embark 5.1 adds two new configuration settings for Smart Contract configuration:
+
+`interfaces` - Any Smart Contract that represent an interface or is used for inheritance
+`libraries` - Any Smart Contract that is used as a library
+
+This makes the configuration less redundant in cases where otherwise the deploy property has been set to false, such as:
+
+```
+deploy: {
+  Ownable: {
+    deploy: false
+  },
+  ...
+}
+```
+
+The above can now be done via:
+
+```
+interfaces: ['Ownable'],
+deploy: {
+  ...
+}
+```
+
+Find the complete documentation [here](https://framework.embarklabs.io/docs/contracts_configuration.html#Defining-interfaces).
+
+## getEvmVersion for conditional tests
+
+Embark tests now include a helper `getEvmVersion` that can be used to consult what EVM the tests are being run on. This is useful when you have certain tests that can only be run in a particular type of node, but you still want to be able to run tests everywhere without them breaking.
+
+For example:
+
+```
+  it("cannot bid after 5 minutes", async () => {
+    const evmVersion = await global.getEvmVersion();
+    if (evmVersion.indexOf("TestRPC") === -1) return;
+
+    increaseTime(5000)
+
+    await assert.reverts(Auction.methods.bid(), {from: web3.eth.defaultAccount}, 'Returned error: VM Exception while processing transaction: cannot bid after auction expired');
+  })
+```
+
+## Nethermind plugin
+
+Embark now comes with a [Nethermind](https://nethermind.io/) plugin.
+More info about the plugin can be found [here](https://github.com/embarklabs/embark/tree/master/packages/plugins/nethermind)
