zellij

This release includes some major long-requested integrations with modern terminals as well as with Zellij itself: nested sessions become a first-class experience, images render through the Kitty graphics protocol, the scrollback understands shell prompts, and the default interface gets a redesign.

Following is a non-exhaustive list of some major and significant changes:

Nested Sessions

Running Zellij inside a Zellij pane (eg. after ssh-ing to a remote machine) is now a first-class workflow. The inner session announces itself to the outer one, and the outer session reacts when its pane gains focus, providing the user with 2 options:

1. Zoom in and control the nested session - the nested session takes up the whole screen until toggled back (Ctrl o + f, or clicking the session breadcrumbs in the tab-bar)
2. Control the nested session on focus - keys and mouse are routed directly to it, with the outer session's chrome dimmed. Ascend back with Ctrl o + ], descend again with Ctrl o + [

The behavior is controlled with the new nested_session_handling config option (ask (default) / fullscreen / descend / never).

Kitty Graphics Protocol

Zellij now implements the Kitty graphics protocol in addition to the existing Sixel support. Image placements are tracked per pane and behave correctly across resizes, relayouts, scrollback, fullscreen and floating/pinned panes. The host terminal needs to support the protocol as well (queried at startup); the feature can be disabled with support_kitty_graphics_protocol false.

Relatedly, Sixel support is now only advertised to applications (through DA1 / XTSMGRAPHICS) when the attached terminal actually supports it.

Shell Integration (OSC 133)

Zellij now parses the OSC 133 "semantic prompt" sequences (emitted by fish out of the box; bash/zsh need a shell integration snippet). This enables:

• Jump between prompts in the scrollback: [ / ] in scroll and search modes
• Select a command with its whole output: m in scroll mode, or triple-click inside the output (opt-out of triple-click with osc133_command_selection in the config)
• Copy the last command's output to the clipboard: c in scroll mode

Also in the selection department: word boundaries for double-click selection are now configurable with word_separators.

New UI

Title frames: pane frames now default to a single title line above each pane instead of a full border. To restore the classic look:

pane_frame_style "full"

The style can also be changed at runtime with zellij action set-pane-frame-style or the new SetPaneFrameStyle keybinding action.

Stacked lists: stacked panes now render as a list of one-line titles with the expanded pane pinned to the bottom, including exit-status indication in collapsed titles and bulk float/embed operations. To restore the previous in-place rendering:

stacked_pane_list false

Some mouse behaviors can also now be specifically opted out of in the config: mouse_hover_tips false (hover help tips) and mouse_scroll_resize false (Ctrl + scroll wheel resizing).

Mobile Web UI + PWA

The built-in web client now detects mobile browsers and switches to a dedicated touch interface: pane/tab pickers, an on-screen keyboard, panning and fit toggling, single-pane fullscreen and a light theme. The web client can also be installed as a standalone app (PWA) directly from the browser, including behind a base_url reverse-proxy prefix.

Per-Client Tab Sizes

Each tab is now sized according to the viewports of only the clients currently viewing it. Clients focused on different tabs no longer force the whole session down to the smallest terminal; clients on the same tab converge

This is a small patch release set out to fix some issues introduced by our host query forwarding system.

Issues such as STDIN stalling, popup panes being blocked and mouse+key movement producing control characters should be fixed.

This is a small patch release to fix some issues found recently in 0.44, as well as some minor long standing annoyances.

The only major feature introduced in this patch is support for CSI 2031: automatically switching between dark/light theme (assuming the terminal emulator itself supports it), as well as forwarding these instructions to the apps running inside Zellij. With this change, comes the new theme_dark and theme_light configuration parameters, that will be used by Zellij when it is instructed to switch, eg.

theme "dracula" // normal theme as it was up until now
theme_dark "dracula" // Zellij will use this when instructed to change to a dark theme
theme_light "catppuccin-latte" // Zellij will use this when instructed to change to a light theme

For convenience (eg. when using a terminal emulator that does not support theme switching), Zellij also now includes the zellij action set-light-theme, zellij action set-dark-theme and zellij action toggle-theme CLI commands to allow doing this manually. (note: when issuing these commands, Zellij will also send a CSI2031 to running terminal applications inside it that requested it, even if the host terminal itself does not support them).

This is mostly a patch release to fix issues discovered in 0.44.0

Some fixed highlights:

• Fixed the performance regression when switching tabs
• Properly report OSC52 support in DA1 which will help applications such as neovim discover Zellij's clipboard support
• Codex scrolling bug: We have accepted a mitigation for an issue where users of Codex would not see scrollback inside Zellij. This was happening due to some off-spec behavior on the part of Codex (nothing wrong, just them relying on a gray area in the specification). This version adjusts the Zellij behavior to match Codex's expectations.
• Various fixes for the recent Windows port
• The web-client now uses the base-url when switching sessions as well
• Fixed some CJK IME cursor positioning support for East Asian languages

New stuff

• Added a focus-pane-with-id and are-floating-panes-visible CLI actions
• Zellij now supports and forwards OSC-99 desktop notifications
• Added zellij --layout-string to allow providing in-line layouts
• Added --tab-id to all CLI actions opening new panes, to be able to open them in a specific tab

For the full list of changes, see the CHANGELOG.
