Lisk v.0.4.0a was released to the testnet a few hours ago !
Correct. It's a minor upgrade for the
testnet. The new version is
not compatible with older versions.
Upgrade infosSome changes in testnet version 0.4.0a- Initial resolution to address collision issue
- Improved block processing logic (for faster syncing over network)
- New peer selection code (for more reliable syncing over network)
- Added ability to snapshot highest round, e.g. --snapshot=highest

Hell Yeah.

Right time to buy more lisk before 0.4.0 version is available for mainnet.
This version implement many bugfixes and new features.
Also, reward for forging is possible with this version. Correct?
