Claude Code 2.1.110: Fullscreen TUI Mode, Push Notifications, and Remote Control Improvements

Claude Code v2.1.110 shipped today with a set of changes that are mostly about the terminal experience rather than model access or pricing. The headline feature is fullscreen TUI mode, which has been requested by the community for a while.

Fullscreen TUI Mode

Running /tui fullscreen switches Claude Code into a flicker-free rendering path that draws on the terminal’s alternate screen buffer, the same approach used by vim, htop, and similar tools. Instead of streaming output that pushes the input box down as Claude responds, the input stays fixed at the bottom and only the messages visible on screen are rendered at any given time.

The official docs describe it as keeping memory usage flat in long conversations. That matters practically: heavy agentic sessions that run through hundreds of messages tend to slow down as the scrollback grows. Fullscreen rendering sidesteps that by only processing what’s visible.

You can tell fullscreen rendering is active because the input box stays put while Claude is working rather than scrolling with output. To switch back, run /tui default.

The setting persists between sessions. If you switch mid-conversation, Claude Code saves the preference and relaunches into fullscreen with the conversation intact.

Push Notifications

The tengu_kairos_push_notifications flag enables a new PushNotification tool that lets Claude notify you when something needs attention during a long agentic session. When Remote Control is enabled and you have “Push when Claude decides” configured, the agent can send notifications to your terminal or, if the Mobile Remote Control is connected, directly to your phone.

This addresses a real friction point in agentic workflows. Running a multi-hour task and stepping away from the machine currently means either checking back repeatedly or discovering that Claude stopped and waited for input 45 minutes ago. Push notifications let the agent escalate proactively instead of going silent.

There’s an agent setting check (agentPushNotifEnabled) that has to be active before mobile pushes go through, which means you opt in explicitly rather than getting notified by every instance you’re running.

Remote Control Improvements

Several commands now work from Remote Control clients, including mobile and web: /autocompact, /context, /exit, and /reload-plugins. The practical effect is that you can manage a running session from your phone without being at the terminal. Starting a long task, walking away, getting a push notification that Claude needs a decision, opening the mobile client to check context and respond, then letting it continue — that flow is now plausible in a way it wasn’t before.

Other Changes in This Release

A few smaller additions in v2.1.110:

Keyboard shortcut update: Ctrl+O now toggles between normal and verbose transcript modes. The /focus command handles focus view toggling separately, which previously required cycling through modes.

Prompt caching TTL controls: Two environment variables give you control over cache behavior. ENABLE_PROMPT_CACHING_1H extends the prompt cache TTL to one hour. FORCE_PROMPT_CACHING_5M forces five-minute caching regardless of other settings. These are mostly useful if you’re running very long sessions where context needs to stay warm between rounds.

Non-streaming fallback cap: The release added a cap on non-streaming fallback retries, though a subsequent patch reverted that change after it caused issues for some setups.

Context

This release follows a busy stretch for Claude Code. The past two weeks brought the removal of Claude Code from the Pro plan (for about 2% of new sign-ups), the addition of xhigh effort mode for Opus 4.7, and the launch of Ultraplan in early preview. The 2.1.x series has been shipping roughly daily, with each release targeting specific rough edges.

The TUI mode is the kind of quality-of-life improvement that doesn’t generate a press release but gets noticed quickly by people who run long sessions. If you’re doing serious agentic work in Claude Code, it’s worth enabling.
