This release comprises several additional features and fixes, in addition to the cumulative patches made against v1.4

A blog post providing more information can be found here


  • Fedora <= 27 are end-of-life. As a result we will be DEPRECATING support for those platforms and any applicable packages and REMOVING them in the future v1.6.0 release. At that time we will SUPPORT Fedora 28 and 29 officially.


Changes to Enforcement of Subjective Whitelist/Blacklist (#6318)

This release enforces the whitelist/blacklist for actions dispatched from within contracts (inline actions) as well as transactions sent by contracts (deferred transactions). This allows a more complete whitelist/blacklist feature than the original spec allowed for.

As this feature is enforced on privileged accounts as well, an additional configuration has been added to allow explicitly specified contracts to act outside of the whitelist/blacklist. This can be useful for taking administrative action on behalf of an account or contract that is otherwise blacklisted. For more details, please see the notes in the PR linked above.

Support reverse iteration & show RAM payer in get table & changes to upper_bound and limit parameters (#6264) (#6285)

This release changes the get_table_rows and get_table_by_scope RPC calls to support iterating the response sequences in reverse. This resulted in a few breaking changes compared to previous versions of the RPC calls. Particularly:

  • The definition of the upper_bound parameter has been corrected; see #6285 for details.
  • The acceptable values of limit for the get_table_rows and get_table_by_scope RPC calls have been changed to be consistent with other RPC methods. Any zero or negative value will return an empty response sequence.

In addition to the changes, the RAM payer for each table row will now be part of the response sequence if the show_payer boolean in the request is set to true.

These changes are supported in cleos with new command line options.

Multi-threaded transaction/block key recovery (#6149) (#6167)

This release introduces the support for recovering keys from cryptographic signatures (aka signature verification) for transactions and blocks across multiple threads. Dispatching these recovery tasks has been pushed forward in the timeline for block validation and relay such that for most blocks the expense associated with them can be effectively mitigated. This should improve block validation times substantially however, it does not affect the cost of producing blocks or the billable expense of retiring transactions on the blockchain.

Add cleos helper command to add eosio.code to permission (#6116)

This release provides (community authored) convenience options for crafting permissions involving the eosio.code meta permission. This permission is essential for allowing contract code to act on behalf of users and making it accessible will allow easier access to better user facing solutions.

Enhancements to cleos multisig approve with proposal_hash, invalidate, and improved review (#6356)

This release modifies cleos support for enhancements to eosio.msig contract that were released as part of EOSIO contracts v1.5.0 and EOSIO contracts v1.3.0. See the PR for more information about the new features.

Replay ctrl-c support (#6237)

This release provides a safe path for responding to signals and gracefully shutting down nodeos during a replay without resulting in a corrupted state database. This has been a pain point for users who replay often, including the development team. The node is left in a state where it should be able to resume replaying from where it left off.

[ALPHA] State history plugin (#5970)

The State History Plugin is a re-imagining of how blockchain data will be retrieved from a running nodeos process in the future. It is intended to serve as the basis of a replacement for the currently deprecated History Plugin with additional features such as support for real-time streaming and access to contract table values and deltas.

This plugin is considered ALPHA at this time and is likely to change substantially before a final release however, the development team invites the community to evaluate it and provide feedback to help guide the development of this product.
