OpenEthereum v3.0.0 is the first release of OpenEthereum client as part of OpenEthereum project, divested from Parity Technologies.

This release marks the transition from Parity Technologies infrastructure and bootnodes to the one managed by OpenEthereum project.

Parity-Ethereum v2.7 users can continue using their existing data folders. Command-line interface has also stayed identical.
Unless specified otherwise, OpenEthereum v3.0.0 will detect if the user's database in the old Parity-Ethereum default path,
and only if it's not found will write to the new default location.

This release includes several major improvements to network and database stack:

• Support for eth/64 protocol and Node Discovery v4 Ethereum Node Records extension.
• Accounts bloom is removed which should decrease the database size.

Due to database changes this is a one-way upgrade. Please back up your database if you plan to continue using Parity-Ethereum v2.7.2.

Note that this release drops support for IPFS and eth/62 protocol. Additionally, it marks light client, private transactions and updater as deprecated features which may be removed in a future release.

Parity Ethereum v2.7.2-stable is a patch version release of parity-ethereum.
Starting in the 2.7.x series of releases, parity-ethereum is switching to a single stable release
track. As a result, any clients that currently receive updates from the beta
track should switch to the stable track.
Due to database format changes, upgrading from 2.5.x or 2.6.x is one-way only.

Parity Ethereum v2.6.5-beta is a patch release that adds block numbers for activating the Istanbul hardfork on mainnet, as well as a large number of various bugfixes, QoL changes, some code cleanup/refactoring and other miscellaenous changes.

This release removes legacy aliases for the mainnet. If you specify --chain homestead, --chain frontier or --chain byzantium, this will need to be changed to one of: --chain eth, --chain ethereum, --chain foundation or --chain mainnet.

This release includes important changes to how snapshots are produced. The size of the Ethereum account state means that producing a snapshot takes a long while; most nodes today are not able to finish before the relevant state is pruned. Starting with v2.6.5, pruning is paused while a snapshot is underway, hopefully fixing the current dearth of recent snapshots. The downside to this is that memory usage goes up while a snapshot is produced.
