@mastra/[redacted], released August 26, adds an optional SandboxComputer capability to workspaces covering screenshots, mouse and keyboard control, display info and wait tools, with providers in @mastra/daytona and a new @mastra/e2b-desktop package bundling E2B command, process and filesystem access plus authenticated noVNC (GitHub). Sandboxes now own a runtime env via MastraSandbox({ env }), and Mastra.shutdown() stops rather than destroys remote sandboxes while Workspace.stop() supports suspend and resume without teardown. Two breaking changes to read: Mastra Code LSP is opt-in behind "lsp": true, and persistPartialOnAbort is gone because canceled runs now retain transcript history unconditionally.
