fedimint

v0.3.3 introduces coordinated shutdown logic, which is required for existing federations prior to upgrading to v0.4.

DO NOT UPGRADE EXISTING FEDERATIONS YET

This release is for client integration and new federation testing only. We still need to backport changes to v0.3 to allow a coordinated upgrade.

Release Notes

• Changing peer's DNS names is now possible.
• On chain deposits are now considered "expert-only" .
• On chain deposit charge fees by default to counter dust attacks.
• Wallet client module implements backup and recovery.
• Wallet client module is robust w.r.t deposit address reuse and rbf transactions.
• Client reconnection backoff was improved.
• RBF withdrawal functionality was removed.
• It's possible to finish DKG (setting up Federation) using only the fedimint-cli tool.

... and many, many internal changes and improvements.

On chain deposits are now considered "expert-only"

Given growing Fedimint usage, Fedimint developers officially recommend applications integrating fedimintd NOT to expose on-chain deposits to the end uses. LN Gateways and Mint guardians are recommended to use fedimint-cli to manage deposits.

In the near future we are planning to implement changes necessary to make on-chain deposits easy to use for all users. For further details, please refer to https://github.com/fedimint/fedimint/issues/5585.

Changing peer DNS names is now possible

Due to incidents where some Federations lost their guardian's DNS name and were unable to rotate DNS names, implementing a scheme that allows it was prioritized and implemented.

In the mid-term future we are planning to remove the DNS requirement altogether.

Wallet client module rewrite

The wallet client module was updated to accommodate deposit address reuse, rbf deposits, and streamline the backup and restore system.

This is the first version that will stay compatible for a long time and provide an upgrade path into the indefinite future.
