- Added new SDK capabilities: array-based provider alias definitions, pulumiResourceName/type helpers, tryOutput for NodeJS, and support for installing package SDKs via `pulumi install`.
- Expanded CLI functionality: exclude flag with dependents, experimental package publishing command, ability to override plugin name/namespace, and improvements to refresh and retain-on-delete behavior.
- Fixed several issues: suppressed duplicate entries in requirements.txt, relaxed state rename validation, removed redundant "same" output messages, enhanced Python error messages, and dropped the pytest-watch dev dependency.
