As Ethereum developers prepare for their 11th backward-incompatible, system-wide upgrade, or “hard fork,” Ethereum 2.0 developers are getting ready to release their first one ever.
Named after the brightest star in the northern constellation of Aquila, the “Altair” upgrade is tentatively scheduled for activation this summer, either in July or August.
Around this time is also when Ethereum’s 11th hard fork, dubbed “London,” is expected for release. One of the goals will be to line up Altair and London for around the same time so that validators can upgrade their Ethereum and Eth 2.0 software in one go, rather than on two different occasions.
The London upgrade is expected to contain controversial code changes such as Ethereum Improvement Proposal (EIP) 1559, which dramatically alters Ethereum’s fee market. The Altair upgrade, on the other hand, will make minor revisions to the dynamics of Eth 2.0.

The Altair upgrade ups the ante on validator responsibilities.
Currently, fully inactive validators lose roughly 11.8% of their staked ether (ETH, -29.47%) balance. After the upgrade, they’ll lose about 15.4%. In addition, validators who are slashed by the network for malicious behavior such as double-signing or double-proposing blocks will get fined 0.5 ETH after hard fork activation instead of 0.25 ETH.
