In a recent tweet, Cardano founder Charles Hoskinson urged stake pool operators to upgrade their nodes to version 1.35.3 in order to get ready for the upcoming Vasil era.
Earlier this week, announced the release of the latest version, which fixes several important issues with previous versions while also providing command-line interface enhancements.
Version 1.35.3 provides full capabilities for the Vasil era, which is why stake pool operators have to get on board before the mainnet launch of the much-anticipated upgrade.
As reported by U.Today, Input Output also released Cardano Rosetta 1.8.0, a set of tools for integrating with the popular proof-of-stake blockchain.
Last week, Input Output stressed that 75% of mainnet blocks have to be created by the final node candidate for the launch of the Vasil hard fork to take place.
The upgrade was initially slated to happen in June. The price of ADA actually rallied in the run-up to the event, but the Vasil launch was postponed due to technical difficulties. In late July, Kevin Hammond, technical manager at Input Output, said that the upgrade would be delayed again.
