Bug Fixes

• Chain Service
  • Fix chain synchronization failure caused by contract timeout error in chain service.
• SQL
  • Fix DB corruption error resulting from integer overflow of DB size limit.

Bug Fixes

• Fix the nil pointer dereference raised whenever GetStateQuery and GetStateAndProof (RPC commands) returns any error. In this situation, the client could not get a correct error response, since the error in the response be always the timeout error due to some internal reason.

Bug Fixes

• Fix LIB upon BP membership change.
• Fix broken tests.

Breaking Changes

• The max block body size (maxblocksize) is hard-limited to carry no more than 8MiB. If maxblocksize is set to a value violating this limit, the aergosvr will not start.

Bug Fixes

• Now aergocli can get a block larger than 4MiB.

Breaking Changes

• Now contract.balance function can be used to get the staking amount of an address and the last staking block height by adding a string constant "stakingandwhen" as its second argument.

Bug Fixes

• The built-in function system.getTimestamp now returns the timestamp value of the current best block in a query, while it returns a OS system time in the previous releases. Warning: any full node under operation must be upgraded to this version.

Bug Fixes

• Fix the chain version handling of the staking amount getter introduced in v2.2.3.

Breaking Changes

• Now contract.balance function can be used to get the staking amount of an address by adding a string constant "staking" as its second argument. Warning: the older versions of Aergo must be upgraded to this version.

Improvements

• Mempool
  • Add two new commands for node administrators: mempool stat, mempool get. The former shows the number of pooled transactions and the number of orphaned transactions for each address; the latter prints the lists of pooled and orphaned transactions hashes for each address. These commands can be run only via the unix domain socket for security reason (For the details, check the corresponding help from aergocli).

Bug Fixes

• Enterprise
  • Remove the obsolete, undocumented cluster command.
  • Prevent the setConf command from generating a whitelist composed of only non-admin members, which makes the whitelist permanently immutable (the resulting whitelist cannot be modified).

Improvements

• Query & transaction execution performance has been improved.
• A new transaction propagation policy has been deployed. By this the number of temporary orphans under heavy load has been largely reduced.
• A transaction includes the hash of the chain ID. The latter is used to verify transactions by the mempool; a transaction having a invalid chain ID hash is rejected. Now the mempool uses the chain ID from a block being created next (not from the current best block).

Bug Fixes

• Now the chain version can be set in genesis.json. #120
• SQL
  • Fix an internal issue leading to a failure of a statement including ‘group by’ clause.
  • Fix a thread safety issue resulting in a segmentation fault.
  • Increase the default DB size to prevent nondeterministic behaviors ending up with a state root mismatch or a receipt root mismatch error.

This release contains a number of new features and improvements.

Latest Docker releases

New features

• Keystore
  • Introducing a new storage format for private keys. Blog article detailing this change
  • All aergocli commands that use an account (e.g. to send a tx) can now use a local keystore instead of a node-based remote keystore.
    • The new default behavior is to use a local keystore at $HOME/.aergo
    • You can change the keystore directory by supplying --keystore /path/to/keystore/
    • To restore the old behavior (using a server provided keystore), pass --node-keystore
    • Deprecation warning: remote node keystore functionality will be removed in future versions. The reason is that this is prone to unsafe use - if used incorrectly with a publicly accessible node, this can expose user information.
  • The internal account module now uses the keystore file format instead of a Badger db. Badger db continues to be supported for old installations. See documentation for details.
    • If you want to migrate your cli accounts, see the documentation
  • CLI and GRPC calls regarding Export and Import of accounts have been adapted to support the new keystore format. ImportAccount has a new parameter Keystore which takes a JSON string. There's also a new method, ExportAccountKeystore.

Breaking changes

• All aergocli commands that use an account (e.g. to send a tx) now use a local keystore by default. You can restore the old behavior of connecting to a node by passing --node-keystore. See the documentation for details
• aergocli account export default output format has changed to the new keystore format. Use --wif to restore the old behavior.
