Claude Code 2.1.300 released

A feature release adding mod capabilities, improving agent handling, and fixing numerous issues across sessions and workflows.

What changed in 2.1.300

• Mods can now add virtualText to prompts, show agent transcripts with $.ui.view(), support right-to-left text direction, and respond to prompt changes via the prompt.change hook.
• Workflow agents can be rewritten in the agent.spawn mod hook; agent hooks now resolve model aliases and fall back to the caller's model if unavailable.
• Cloud sessions, worktrees and remote control improved: fixed organization policy detection, reftable repository support, container replacement handling, and connection renewal after sign-in errors.
• Fixed transcript loss after crashes, background command issues, and missing OpenTelemetry attributes; improved artifact updates to combine small changes into single calls.
• Various UI fixes: agents view input handling, branch display, file path naming, and VSCode integration with selection attachment, fast mode credit handling, and drag-drop on Windows and WSL.

Check before you update

• Removed --sandbox and --no-sandbox flags from claude remote-control; use sandbox.enabled setting instead.
• CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST sessions now ignore CA-bundle, tool-proxy, and git TLS variables from settings.
