March 2025 monthly summary for idos-sdk-js (idos-network/idos-sdk-js). Key features delivered include upgrading Kwil-js integration to v0.9.x with PositionalParams and object-based action params, plus catalog packaging and an empty-input workaround to ensure robust action invocation. Core SDK response handling was standardized across endpoints, addressing inconsistent call results. User profile retrieval flow was corrected to ensure accurate data access. Environment hygiene was improved by reinstalling dependencies, cleaning the lockfile, removing deprecated dbid usage, and stabilizing the test suite. CI enhancements were added to automate tests on pushes/PRs, complemented by codebase simplifications (removal of the standalone playground app) to reduce maintenance surface. These updates collectively boost reliability, reproducibility, and developer productivity while maintaining Kwil-js compatibility and strengthening overall system resilience.

February 2025: Focused on security, reliability, and maintainability of idos-sdk-js. Delivered three high-impact changes: a DWG-based credential issuance flow with new request/sign methods and updated credential creation flow; a KGW logout fix to terminate sessions securely; and an upgrade to Kwil client (v0.10) with an API refactor introducing distinct call vs execute paths. These changes improve security, prevent authentication conflicts, and streamline developer experience through clearer API semantics and payload builders.
