- Added new CLI capabilities: support for v4 checkpoints/deployments, qualified registry template names in pulumi new, and always‑generate resources on import.
- Enhanced SDKs: introduced Bun as a Node.js package manager, exported getRootDirectory in Node.js and Python modules, and added on‑error callbacks and object‑type config parsing.
- Fixed multiple engine and CLI bugs, including .tar.gz template extraction, Accept header mismatch, panic on up refresh, destroy step registration, program hang, and delete‑hook handling.
