🚀 Highlights

Ignite CLI v29.0.0 is finally there! This new version is packed with new features and dev ux improvement:

• As always, Ignite scaffolds the latest Cosmos Stack: Cosmos SDK v0.53, IBC-go v10 (IBC v1 and v2 enabled), and all the latest features enabled 💥.
• New scaffolding commands: config, params and new scaffolding flags: --default-denom to allow you to do more, with less.
• Thanks to an overhaul of the CLI internal, Ignite now scaffolds a chain without cluttering it with the infamous // this line is used by starport scaffolding line.
• Scaffolded modules now uses cosmossdk.io/collections for state management.
• New xast package to help developers make Ignite Apps even easily (an Ignite EVM App is coming, thanks to that).
• The CLI stays compatible with all Ignite Apps, only some are being updated to work with IBC-go v10 (notably Ignite Wasm App).
• Improved tooling, by using the latest Go 1.24 and buf features. Only a ignite doctor away, when upgrading from v28.

Upgrade today and supercharge your chain development with the best Ignite experience yet!
