Claude Code v2.1.110 Adds Push Notifications and /tui Command for In-Session Fullscreen

Anthropic shipped Claude Code v2.1.110 on April 15, adding push notification support for Remote Control sessions and a new /tui command that switches to fullscreen rendering without interrupting the current conversation.

Push Notifications for Remote Sessions

Claude can now send a push notification to your mobile device to signal that a Remote Control session needs your attention or has completed. Two conditions have to be met: the session must be running with Remote Control active, and you need the “Push when Claude decides” option enabled in your Remote Control config.

When both are on, Claude decides when to fire the notification, either when it’s done with a task or when it hits something that needs a human response. You set it up once and step away. The practical difference from just checking in periodically: you’re not guessing when the session is done.

Claude Code’s Remote Control launched in February, letting you monitor and steer a running session from github.com or the mobile app. This update completes the loop: the session can now reach out to you rather than waiting for you to check back.

/tui: Switch to Fullscreen In-Session

Claude Code has had a fullscreen, no-flicker terminal rendering mode since April. The original version required enabling it before starting a session. Version 2.1.110 adds /tui fullscreen (and a corresponding tui config option) so you can switch modes inside an already-running conversation without starting over.

There’s also an autoScrollEnabled config toggle that pairs with fullscreen mode: when disabled, the view doesn’t chase the output tail, which is useful when you’re reviewing earlier messages during a long session.

/focus and /ctrl+O Changes

The Ctrl+O keyboard shortcut previously cycled through rendering views. That behavior is now split: Ctrl+O only toggles between normal and verbose transcript modes, and a new /focus command handles the full-window focus view separately.

This is a cleaner split. If you’ve been using Ctrl+O and your muscle memory expects it to toggle focus, you’ll need to switch to /focus.

Remote Commands Now Work from Mobile

All the new session commands, /tui, /focus, /autocompact, /context, /exit, and /reload-plugins, now work when issued from a Remote Control web or mobile client. Previously, some commands were only available from the local terminal. This makes it more practical to manage a running session entirely from your phone without needing to be at the machine.

Bug Fixes

Two notable fixes: a duplicate message rendering bug in iTerm2 and Ghostty with DEC 2026 terminal support is resolved, and a hang where MCP plugins would get stuck in “connecting” state is fixed.
