Feature Gate Activation Schedule

Feature Gate Activation Schedule

The scheduling of feature gate activations is be based on the following principles:

• Relative priority
• The same order on each network

Those two principles will not always agree, exceptions will occur.

Feature gate activation so far has been ad-hoc, to help organize and communicate the upcoming feature gate activations the following table will indicate which features will be activated next and on which networks.

• Feature gates are ordered by priority, highest at the top, priority might change and circumvent activation.
• When a feature gate is activated on a network, the epoch will be added to the table by the person who activated the feature gate.
• The feature gate in the first row is implicitly next to be activated on mainnet beta
• Once a feature gate is activated on mainnet beta the person who activated the feature gate must remove it from the table.
• Feature gate owners are responsible for inserting their feature gates into this list following the above principles, exceptions will occur, get consensus from others before re-ordering priority.
• Some feature gates will need to be soaked before being activated on the next network, soaking will delay all lower-priority feature gates, exceptions will occur.
• Feature gates should be activated one at a time per network, exceptions will occur.

To determine which feature gate will be activated next:

• Feature gates must be activated on testnet, then devnet, then finally mainnet beta
• For each network, the next feature gate that has not been enabled will be enabled next

Example

Given the following schedule:

• nWBqjr3gpETbiaVj3CBJ3HFC5TMdnJDGt21hnvSTvVZ will be activated on testnet next
• DpJREPyuMZ5nDfU6H3WTqSqUFSXAfw8u7xqmWtEwJDcP will be activated on devnet next
• 7GUcYgq4tVtaqNCKT3dho9r4665Qp5TxCZ27Qgjx3829 will be activated on mainnet beta next

Version Floor

The version floor is the current minimum supported software version for a cluster. As new feature gates are activated, the version floor is raised to match the software release that the feature gate shipped in. For minor version updates on mainnet-beta the version floor will be raised (and activations will begin) two full epochs after 95% of stake adopts the new minor version.
