Mar 1, 2025March 2025 monthly performance summary for zowe-cli focusing on security, session management, and maintainability. Delivered major authentication and session-management improvements, enabling per-session credential caching, multi-session support, and centralized cache handling by moving authCache into Session and introducing cacheCredsAndAuthOrder usage across code paths, tests, and environments. Implemented Censor.censorSession with unit tests. Advanced auth/token flow with resets of authOrder, token-based requests, and expanded tests for base64EncodedAuth and AuthOrder. Conducted code quality and test-suite cleanup (lint fixes, removal of prototype/AuthOrder files). These updates reduce risk in multi-session enterprise deployments, improve security auditing, and boost developer productivity through cleaner, more maintainable code.

Jan 1, 2025January 2025 focused on strengthening and centralizing authentication for zowe/zowe-cli, delivering a scalable AuthOrder system that determines credentials from profiles, CLI arguments, or environment variables while maintaining backward compatibility. Implemented base64EncodedAuth support for secure basic authentication and introduced caching and persistence utilities to apply the correct authentication sequence across REST clients. Documentation updates clarified usage, constraints (authOrder as a string; not sourced from environment variables), and included a rest-client actions diagram. Key code evolutions include adding AuthOrder.ts, integrating it into session configuration (ConnectionPropsForSessCfg.ts), and refining session credential handling to avoid prompts when base64Auth is present. The changes collectively reduce user friction, improve security posture, and enable consistent REST client behavior across environments.
