The planned hardfork schedule is as follows: Magma hardfork blocknumber & estimated date
Baobab: 98347376 11:00 AM (UTC+9) Aug 8
Cypress: 99841497 11:00 AM (UTC+9) Aug 29
NOTE: This version updates the version of the database to support snapshot sync. You cannot downgrade to the older versions with existing data after updating to v1.9.0.
NOTE: Snapshot sync is shipped on this version, but not yet enabled as default. The state snapshot should be generated on remote peers to sync properly, but it is not yet ready. You can manually enable snapshot sync with --syncmode snap, but be advised that we expect it would find suitable peers after a few weeks. This feature is only experimental at this moment.

Klaytn v1.9.0 contains a protocol upgrade that results in backward incompatible changes, like the Ethereum hardforks. All Baobab/Cypress nodes would thus have to be upgraded to v1.9.0 or higher before the target block number. The name of the hardfork is ‘Magma’. The hardfork contains an implementation of the dynamic gas price mechanism suggested in .
