Changelog

Upcoming Changes in v0.9

Breaking Changes to Command Line

In v0.9, changes will be made to the command line options to improve usability. These will be breaking changes; that is, in many cases the v0.8 command line options will no longer work. The Pantheon documentation will be updated to reflect these changes. Any further information required about the changes will be included in the v0.9 release notes.

Private Network Quickstart

In v0.9, the Private Network Quickstart will be moved to a separate repository and the existing Private Network Quickstart removed from the Pantheon repository. The Private Network Quickstart tutorial will be updated and use the Private Network Quickstart in the separate repository.

0.8.5

Indefinitely delays the roll-out of Constantinople on Ethereum Mainnet due to a potential security issue detected.

Additions and Improvements

  • Remove Constantinople fork block #574

Technical Improvements

  • Rename IBFT message packages #568

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, or referring to the custom configuration file or genesis file.

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 Pantheon 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:

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 Pantheon. For example:

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.
