# Changelog

## 1.4 Beta 3 

### Additions and Improvements 

- CLI option to enable TLS client auth for JSON-RPC HTTP [\#340](https://github.com/hyperledger/besu/pull/340)

Added CLI options to enable TLS client authentication and trusting client certificates: 
~~~
--rpc-http-tls-client-auth-enabled - Enable TLS client authentication for the JSON-RPC HTTP service (default: false)
--rpc-http-tls-known-clients-file - Path to file containing client's certificate common name and fingerprint for client authentication.
--rpc-http-tls-ca-clients-enabled - Enable to accept clients certificate signed by a valid CA for client authentication (default: false)
~~~
If client-auth is enabled, user must either enable CA signed clients OR provide a known-clients file. An error is reported 
if both CA signed clients is disabled and known-clients file is not specified.

- Stable Plugins APIs [\#346](https://github.com/hyperledger/besu/pull/346)

The `BesuEvents` service and related `data` package have been marked as a stable plugin API. 

### Bug Fixes

- Return missing signers from getSignerMetrics [\#343](https://github.com/hyperledger/besu/pull/)

### Experimental Features

- Experimental support for `trace_replayBlockTransactions` - multiple PRs 

Added support for the `trace_replayBlockTransactions` JSON-RPC call. To enable this API add 
`TRACE` to the `rpc-http-api` options (for example,  `--rpc-http-api TRACE` on the command line). 

This is not a production ready API.  There are known bugs relating to traced memory from calls and 
returns, and the gas calculation reported in the flat traces does not always match up with the 
correct gas calculated for consensus.

## 1.4 Beta 2 

### Additions and Improvements 

- Enable TLS for JSON-RPC HTTP Service [\#253](https://github.com/hyperledger/besu/pull/253)

Exposes new command line parameters to enable TLS on Ethereum JSON-RPC HTTP interface to allow clients like EthSigner to connect via TLS: 
`--rpc-http-tls-enabled=true`
(Optional - Only required if `--rpc-http-enabled` is set to true) Set to `true` to enable TLS. False by default.
`--rpc-http-tls-keystore-file="/path/to/cert.pfx"`
(Must be specified if TLS is enabled) Path to PKCS12 format key store which contains server's certificate and it's private key
`--rpc-http-tls-keystore-password-file="/path/to/cert.passwd"`
(Must be specified if TLS is enabled) Path to the text file containing password for unlocking key store.
`--rpc-http-tls-known-clients-file="/path/to/rpc_tls_clients.txt"`
(Optional) Path to a plain text file containing space separated client’s certificate’s common name and its sha-256 fingerprints when 
they are not signed by a known CA. The presence of this file (even empty) enables TLS client authentication. That is, the client 
presents the certificate to server on TLS handshake and server establishes that the client certificate is either signed by a 
proper/known CA. Otherwise, server trusts client certificate by reading the sha-256 fingerprint from known clients file specified above. 

The format of the file is (as an example):
`localhost DF:65:B8:02:08:5E:91:82:0F:91:F5:1C:96:56:92:C4:1A:F6:C6:27:FD:6C:FC:31:F2:BB:90:17:22:59:5B:50`

### Bug Fixes 

- TotalDifficulty is a BigInteger [\#253](https://github.com/hyperledger/besu/pull/253). 
  Don't try and cast total difficulty down to a long because it will overflow long in a reasonable timeframe.

## 1.4 Beta 1 

### Additions and Improvements 

- Besu has moved from an internal Bytes library to the [Apache Tuweni](https://tuweni.apache.org/) Bytes library.  This includes using the library in the Plugins API interfaces. [#295](https://github.com/hyperledger/besu/pull/295) and [#215](https://github.com/hyperledger/besu/pull/215)
- Besu stops processing blocks if Orion is unavailable [\#253](https://github.com/hyperledger/besu/pull/253)
- Added priv_call [\#250](https://github.com/hyperledger/besu/pull/250).  Invokes a private contract function locally and does not change the private state.
- Support for [EIP-2124](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-2124.md), which results in faster peer discovery [\#156](https://github.com/hyperledger/besu/pull/156)

## 1.3.8 

### Additions and Improvements 

- `admin_generateLogBloomCache` JSON-RPC API to generate a cache of the block bloombits that improves performance for log queries [\#262](https://github.com/hyperledger/besu/pull/262)

## Critical Fix in 1.3.7 

1.3.7 includes a critical fix for Ethereum MainNet users and the Muir Glacier upgrade. We recommend users of Ethereum public networks 
(MainNet, Ropsten, Rinkeby, and Goerli) upgrade immediately. This upgrade is also strongly recommended for users of private networks.

For more details, see [Hyperledger Besu Wiki](https://wiki.hyperledger.org/display/BESU/Mainnet+Consensus+Bug+Identified+and+Resolved+in+Hyperledger+Besu). 

## Muir Glacier Compatibility

For compatibility with Ethereum Muir Glacier upgrade, use v1.3.7 or later.

## 0.9

### Breaking Changes to Command Line

Breaking changes have been made to the command line options in v0.9 to improve usability. Many v0.8 command line options no longer work. 

The [documentation](https://docs.pantheon.pegasys.tech/en/latest/) has been updated throughout to use the changed command line options and the [command line reference](https://besu.hyperledger.org/en/stable/) documents the changed options. 

| Previous Option                     | New Option                                                                                                                                                                                                                                  | Change                            |

Indefinitely delays the roll-out of Constantinople on Ethereum Mainnet due to a [potential security issue](https://blog.ethereum.org/2019/01/15/security-alert-ethereum-constantinople-postponement/) detected.

## 0.8.4

### Docker Image

If you have been running a node using the v0.8.3 Docker image, the node was not saving data to the 
specified [data directory](https://besu.hyperledger.org/en/stable/),
or referring to the custom [configuration file](https://besu.hyperledger.org/en/stable/)
or [genesis file](https://besu.hyperledger.org/en/stable/). 

To recover the node key and data directory from the Docker container:
`docker cp <container>:/opt/pantheon/key <destination_file>`
`docker cp <container>:/opt/pantheon/database <destination_directory>` 

Where `container` is the name or ID of the Docker container containing the Besu node. 

The container can be running or stopped when you copy the key and data directory. If your node was 
fully synchronized to MainNet, the data directory will be ~2TB.  

When restarting your node with the v0.8.4 Docker image:

* Save the node key in the [`key` file](https://besu.hyperledger.org/en/latest/Concepts/Node-Keys/#node-private-key) in the data 
    directory or specify the location using the [`--node-private-key` option](https://besu.hyperledger.org/en/stable/).  
* Specify the `<destination_directory` as a [volume for the data directory](https://besu.hyperledger.org/en/stable/).

## 0.8.3 

### Breaking Change to JSON RPC-API 

From v0.8.3, incoming HTTP requests are only accepted from hostnames specified using the `--host-whitelist` command-line option. If not specified, the default value for `--host-whitelist` is `localhost`. 

If using the URL `http://127.0.0.1` to make JSON-RPC calls, use `--host-whitelist` to specify the hostname `127.0.0.1` or update the hostname to `localhost`. 

If your application publishes RPC ports, specify the hostnames when starting Besu. For example:  

```json
pantheon --host-whitelist=example.com
```
 
Specify `*` or `all` for `--host-whitelist` to effectively disable host protection and replicate pre-v0.8.3 behavior. This is not recommended for production code.
