• Aergo-JDBC: Aergo now includes a JDBC-compatible database interface. Use this to connect to a smart contract as if it were a database. For this, the SQL support in Lua contracts was improved. Note that this feature is only available on private networks.
• Polaris version filter: Prevent older version aergoserver from getting peer list

Improvements

• [RAFT] add ElectionTickCount parameter in RaftConfig. Default value is 10.
• [P2P] Fix panic during shutdown
• [P2P] Improve policy of retrying tx notice
• [brick] print event msgs during contract call

• [P2P] Change behavior of whitelist configuration

This is a patch release containing a few improvements regarding P2P communication and a lua script execution bug fix.

Bug Fixes

• [ctr/lua] bignum.pow didn't return the correct result in certain cases
• [P2P] Whitelist
  • Fix add or remove whitelist conf was not applied immediately
  • Change behavior of whitelist not to affect outbounding peers
  • Changing whitelist configuration will trigger immediate ban now.

This is a patch release containing a few bug fixes regarding the Raft consensus implementation.

Bug Fixes

• [RAFT] fix logging for work of blockfactory
• [RAFT] fix bug: block factory generates work of same height.
• [RAFT] add validation of address in ValidateEnterpriseTx

This is a patch release containing a few bug fixes, mostly regarding the Raft consensus implementation.

Bug Fixes

• [Mempool] Remove whitelist statistics in public network
• [P2P] Add retry tx notice
• [RAFT] Fix bug that make fork of chain when leader changed
• [RAFT] Add blockfactorytickms=30 to config of test scripts
• [RAFT] Check if term of leader is changed before propose.
• [RAFT] Add debug feature: block factory sleeps before proposing block
• [RAFT] Minor refactoring: leader check api
• [RAFT] Add config parameter : StopDupCommit

This release contains a number of improvements and new features, especially regarding enterprise support. This is an important step towards integration for enterprise customers.

These features are active when a chain is initialized in private mode and are not available on public networks.

Latest Docker releases

New Features

• Enterprise

  • Enterprise administrators: Users can set up administrators to control their private network
  • RPC permission control using TLS certification on private network
  • P2P Whitelist: Add whitelist feature based on ip addres and/or peerid

  • Raft
    • Raft version 2 added. In verion2, blockchain and raft logs are tightly coupled.
    • Replace network framework by P2P
    • support Dynamic membership management by Enterprise transaction

Breaking Changes

• RPC, StateQuery: storageKeys type was changed to bytes (which should be the hash of the key name; was previously just a string of the name)
• Smart Contract Default function: If the function name is not found, it no longer calls the default function and raises an error instead.

Improvements

• RPC

  • TLS support:The GRPC API can now be configured to use TLS connections (HTTP2 only, not for grpc-web; for now continue to use proxy servers for grpc-web over https)
  • GetChainInfo (Total staking): Support current total staking in GetChainInfo

• Smart contract

  • Support for multi dimensional state.map, state.array

This is a patch release containing a bug fix regarding smart contract execution.

Bug Fixes

• [ctr/lua] bugfix of sorting about key of table

This is a patch release containing several bug fixes regarding smart contract execution.

Bug Fixes

• [ctr/lua] allow 0 byte to key at setitem
• [ctr/lua] tx error if conversion of return value to json fails
• [ctr/lua] If matched function name does not exist, changed the error to occur even if the default function exists

Another month, another feature release! This release comes with a number of API changes and new features.
