What’s new
Spark Name Renewal and Transfer Without Double Paying
Users can now extend or transfer their Spark Name and have the leftover validity period credited - so you only pay for the time you are actually adding. This makes long-term use of Spark Names more practical and cost-efficient, and removes a friction point for users who want to keep their on-chain identity current.
Spark Names are Firo’s human-readable on-chain address system, letting you send and receive FIRO using a simple alias like @sparky instead of a long cryptographic address - all while preserving the full privacy guarantees of Lelantus Spark.
Spark Name List Refresh Fix
A bug causing the Spark Name list in the wallet to not refresh correctly has been resolved. Registered names will now display accurately and update as expected.
Qt Wayland Support
This release adds Wayland display protocol support for the Qt wallet. This benefits Linux users running Wayland compositors, improving compatibility and stability of the desktop wallet on modern Linux environments.
RPC and Mempool Improvements
The getspentinfo RPC call is now properly registered, and stale mempool spent index entries are cleaned up when transactions are removed. This improves reliability for developers and node operators querying spent transaction data.
Update Deadline
This is a mandatory update. All wallets, full nodes, and masternodes must be updated to v0.14.16.0 before block 1,329,000, approximately 22 June 2026.
