+# Nushell 0.116.1
+
+Today, we're releasing version 0.116.1 of Nu. This patch release improves TUI widgets with live stream updates, customizable borders and titles, and more reliable pane resizing, while fixing completions and refining startup-time reporting.
+
+# Where to get it
+
+Nu 0.116.1 is available as [pre-built binaries](https://github.com/nushell/nushell/releases/tag/0.116.1) or from [crates.io](https://crates.io/crates/nu). If you have Rust installed you can install it using `cargo install nu`.
+
+As part of this release, we also publish a set of optional [plugins](https://www.nushell.sh/book/plugins.html) you can install and use with Nushell.

+## Deprecations
+
+### Deprecation: `tui label --title` is now `tui label --titlebar` <JumpToc/> <PrBy :pr="19102" user="fdncred" />
+
+To put a label in the top bar, use `tui label --titlebar "My app"` instead of `tui label --title "My app"`. The old switch still works but warns on first use and is scheduled for removal in 0.118.0.
+
+## Additions <JumpToc/>
+
+### Widgets can set their border title with `--title` <JumpToc/> <PrBy :pr="19102" user="fdncred" />
+
+Use `--title <text>` to name the border of `tui table`, `tui tree`, `tui select`, `tui log`, `tui preview`, `tui search`, or `tui textbox`. The title replaces the widget's default name, while row counts and status indicators remain visible. For example:
+
+```nu
+ls | tui table --title files | tui run
+```
+
+The table's border now reads `files (12)` rather than `table (12)` when it has 12 rows. For `tui preview`, the previewed filename follows the custom title, as in `files (Cargo.toml)`; without a file to preview, only the custom title appears. For `tui search`, the title also becomes the default placeholder unless `--placeholder` is set. An empty `--title` is rejected.
+
+### Choose `tui` border lines with `--border` or `$env.config.tui.border_type` <JumpToc/> <PrBy :pr="19100" user="fdncred" />
+
+Bordered TUI widgets now accept `--border <name>` to change their outline. This includes `tui table`, `tui tree`, `tui select`, `tui log`, `tui preview`, `tui search`, `tui textbox`, `tui box`, and the dropdowns opened by `tui menu`. The names match `table --theme` options, and the flag offers completion for valid border names.
+
+```nu
+ls | tui table --border rounded | tui run
+
+$env.config.tui.border_type = "double"
+ls | tui table | tui run
+```
+
+`$env.config.tui.border_type` sets the default for all TUI borders, including menu dropdowns and dialog frames. An individual widget's `--border` overrides it. The default is `single`, which preserves the previous appearance. For example, `rounded` draws `╭─╮`, `double` draws `╔═╗`, and `heavy` draws `┏━┓`; styles such as `basic`, `dots`, and `markdown` are available too.
+
+`none` and `default` are not valid TUI border names. Use `frameless` for an outline with no visible lines: it still occupies one cell, and the widget's title remains visible. When a widget has its own `--border`, its `widgets` record includes the selected border name.
+
+## Bug fixes <JumpToc/>
+
+### TUI widgets now display streamed data as it arrives <JumpToc/> <PrBy :pr="19099" user="fdncred" />
+
+Slow and endless streams now update TUI widgets while `tui run` is open. A log displays each row as it arrives, and a progress bar advances as its input runs instead of starting at 100%:
+
+```nu
+1.. | each {|n| sleep 1sec; $n} | tui log | tui run
+```
+
+This also works for streams piped into widgets in a child list, such as `tui split [(tail -f app.log | tui log) (ls | tui table)]`.
+
+TUI builders now always output a `tui` value: piping one into a non-TUI command, such as `1.. | tui table | first`, no longer returns the input rows. A TUI value saved with `let` reads its stream on the first run. If the stream finishes, later runs display the same rows; if it stops early, later runs display no rows. When a `tui run` closure, `tui bind`, button, or menu hook returns data, that data replaces the piped data for the rest of the run, without additional rows arriving from the stream.
+
+Streams now keep around 100,000 of their newest rows, dropping older rows in batches of 12,500. Up to 12,499 extra rows can appear between drops, and `tui log --max-lines` can raise the limit further. Piping data into a child list whose widgets all specify `--data` now produces an error instead of silently ignoring the input.
+
+### TUI split panes now resize reliably with keyboard and mouse <JumpToc/> <PrBy :pr="19101" user="fdncred" />
+
+After focusing a `tui split` with Tab, the arrow keys or `h`/`j`/`k`/`l` move its first divider in either direction. Each press moves it one cell on splits up to 100 cells wide or tall when there is room; on larger splits, a press may move it a few cells. This works for both the default side-by-side layout and `--vertical`, including short splits where resizing previously got stuck.
+
+```nu
+ls | tui split [(tui table) (tui preview)] | tui run
+ls | tui split [(tui table) (tui preview)] --vertical | tui run
+```
+
+Dragging a divider with the mouse now places it as close to the pointer as the surrounding panes allow, including dividers between later panes in a split. Resizing preserves at least one cell for every pane, and fixed-height splits such as a row of buttons no longer respond to keyboard resizing.
+
+### Completion menus stay open when nothing matches <JumpToc/> <PrBy :pr="19129" user="kronberger-droid" />
+
+An open completion menu no longer closes when the typed text stops matching.
+It shows `NO RECORDS FOUND` and fills again once the text matches, as it did before 0.116.
+Cancelling an `@interactive` picker with Esc now closes its menu right away, and Tab on the same line opens the picker again.
+
+### Startup time now starts inside Nushell and is available throughout startup <JumpToc/> <PrBy :pr="19136" user="fdncred" />
+
+`$nu.startup-time` is now measured from the start of Nushell's `main` function, rather than from when the operating system created the process. It no longer includes the time spent loading the executable and its libraries, and `exec nu` starts a fresh measurement instead of carrying over the previous program's time. This applies across platforms.
+
+Before startup finishes, `$nu.startup-time` now contains the elapsed startup time instead of `-1ns`. It is available in config files, `-e` commands, and the `--mcp`, `--lsp`, `--dap`, and `--ide-check` modes. The `--ide-hover`, `--ide-complete`, `--ide-goto-def`, and `--ide-ast` modes can now also access `$nu`, enabling type information for constants built from it and completion of `$nu` fields. Config files loaded with `nu --mcp` now see `$nu.is-mcp` as `true`.
+
+With `--log-level perf`, the "before main" line is gone. The final REPL startup line is labeled "startup (main to first prompt)", and the `--mcp` and `--lsp` startup lines no longer include the time spent serving the rest of the session.
+
+### Other fixes <JumpToc/>
+
+- Fixed some incorrect cell path parsing. ([#19112](https://github.com/nushell/nushell/pull/19112))
+- Fixed a regression since 0.115 where custom completers on a `def --wrapped` rest parameter were not called for arguments starting with `-`, so `what --<Tab>` only offered declared flags. ([#19130](https://github.com/nushell/nushell/pull/19130))
+
+## Other changes
+
+### Changed `tui` records <JumpToc/> <PrBy :pr="19102" user="fdncred" />
+
+For scripts that inspect TUI values, a titled widget now has a `title` field in its `widgets` record, and a top-bar label's `slot` is now `titlebar` instead of `title`. When nothing is being previewed, `values.<preview id>.title` is now an empty string rather than `preview`.
