Aion v0.2.7 - Mainnet Island Peak

Bug fix

• transaction error handling (PR#485)
• console check in CLI node (PR#494)
• aion account format check in keystore (PR#481)
• p2p handshake version length bug (PR#497)

Enhancement/Feature

• Java API support get account nonce.

Migration

• new db option in the config settings, can keep using v0.2.5 settings. If you want to skip db checking in the begin of the aion kernel launch. need to add <check_integrity>false</check_integrity> in the DB category.

Checksum

• a checksum is a small-sized datum derived from a block of digital data for the purpose of detecting errors which may have been introduced during its transmission or storage.

How to use Checksum

• download the aion kernel release binary and the checksum file (the file name SHA1SUMS) and put the files into the same folder.
• open terminal and go to the folder.
• type in sha1sum -c SHA1SUMS
• if the binary file is complete and no error, you will see the message output like this :
  aion-v0.2.6.2f8fdfa-2018-05-10.tar.bz2: OK

• aion.sh not working with symlinks (Issue#416)
• unable to generate blocks with seed mode enabled (Issue#455)

Enhancement/Feature

• database check and corrupt data fix when the kernel launch (can be skipped by changing the check_integrity of the DB category in the config file)
• web3 API eth_accounts reenable

Joining the network requires a new config, and database. Previous keystore files can be carried over.

Changelog:

• Revised RPC Server
• Improved double-hashing mining algorithm
• Fixed compatibility with certain contracts
• Revised configurations updated to match latest changes

Aion v0.2.0

NOTE: This build is run on a separate TestNet (dubbed Q2/Ascent), joining this testnet requires a completely refreshed configuration file, genesis and database. Previously generated keystores will also fail to work, for the purposes of this TestNet please generate new keys for your accounts.

This update also breaks miner compatibility check here for updated pool and reference miner builds.

• Changes the Address of accounts, from publicKey to a modified hash of the publicKey.
• Changes some consensus rules regarding transaction validation.
• Includes some parameter changes.

Aion v0.1.19

Note: Miners must be updated correspondingly, see aion_miner release page for details

Changelog:

• Revises P2p layer for higher throughput
• Revises Syncing layer for better branching abilities
• Bug fixes for Transaction Pool
• Revises internals for RPC server
• Added guards against I/O intensive operations, reduces changes of OOM
• Adds a heapdump parameter on OOM, should aid in diagnostics
