# 1.0.0

**Released on April 17th, 2026**

Wallet SDK v1 is the new long-term API shape for application development.
Rather than being an additive patch to v0, v1 introduces a cleaner and more explicit model focused on composability, multi-party flows,
and transport flexibility.

**Why move to v1**

* Stateless and safer by default: v1 removes global SDK/controller party state and requires explicit `partyId` at call time, which improves
  thread safety and makes concurrent multi-party operations much easier to reason about.
* Clearer transaction lifecycle: flows are modeled as explicit `prepare -> sign -> execute` steps, improving observability and reducing hidden behavior.
* Better API organization: v0 controllers are replaced by namespaces (`ledger`, `party`, `token`, `amulet`, `user`, `asset`, `events`)
  with clearer boundaries and easier discoverability.
* More flexible integration model: v1 supports static configuration and provider-based initialization, making it easier to integrate with browser,
  dApp, remote wallet, and alternative transport setups.
* Improved extension model: optional functionality can be enabled via `extend()` which keeps base initialization small and purpose-driven.

This release note intentionally avoids listing every single method-level change.
