v0.4.0.1

This is a mandatory update release.

This release mainly allows the user to use the Aion Java contract to interact with the Aion blockchain network after the hard fork (block# 3346000 on Mainnet). It is one of the biggest milestones for the Aion ecosystem. Additionally, we have modified the monetary policy to align with the Aion whitepaper.

Migration guide:

To upgrade your current running node, you must overwrite the fork.properties file in the <aion executing path>/<network>/config/ folder. This can be done either by overwriting this file with the following properties or by copying the fork.properties file in <aion executing path>/config/<network>/ from the new release.

  • Fork.properties before 0.4.0 (Mainnet):
fork0.3.2=1920000
  • Fork.properties since 0.4.0 (Mainnet):
fork0.3.2=1920000
fork0.4.0=3346000
  • Fork.properties before 0.4.0 (Mastery):
fork0.3.2=1132000
  • Fork.properties since 0.4.0 (Mastery):
fork0.3.2=1132000
fork0.4.0=2393000
