Release Notes:

- Fixed clicking on non-selectable picker entries (e.g. section headers)
confirming the currently selected item.

When a diagnostic-triggered prediction returns no edits, don't fall back
to requesting another diagnostic prediction. This was causing an
infinite loop that burned through the API rate limit until hitting 429
errors.


Release Notes:

When multiple `queue_prediction_refresh` calls land in the same
synchronous frame, all spawned tasks would read the same throttle state
and each send an identical cloud request.

Now the second task would see that the first request has been sent and
would quit.

Nightly only since no tool is using streaming on Preview.

Tools that used streaming could deadlock when the upstream LLM API
stream exited early without ever sending a ToolUse with `input_complete`
set to `true`. This is now fixes by manually dropping the tool input
channels.

Turns out `Editor::newline_below` was not respecting the `read_only`
flag because it uses buffer.edit. `Editor::newline` and
`Editor::newline_above` behaved correctly because they used
`editor.edit` which ignores edits if `read_only` is true.

Added an early return if the editor is read only, also added it to
newline/newline_above for clarity.

Release Notes:

- Fixed an issue where newlines could be inserted into read-only editors

Fixes #50526
Fixes https://github.com/zed-industries/zed/issues/42841
Fixes https://github.com/zed-industries/zed/issues/49875

### Summary

Fix `autosave: on_focus_change` not firing reliably when leaving editors
with nested focus targets (e.g. multibuffer/search flows).

### Root cause

Autosave on focus change was wired to `on_blur` of the item focus
handle.
`on_blur` only fires when that exact handle is the focused leaf, which
misses common descendant-to-outside focus transitions.

## Fix

In `crates/workspace/src/item.rs`, switch autosave subscription from:
     - `cx.on_blur(&self.read(cx).focus_handle(cx), ...)`

to:
     - `cx.on_focus_out(&self.read(cx).focus_handle(cx), ...)`

Autosave behavior and guards remain unchanged:
- only for `AutosaveSetting::OnFocusChange`
- only when focus truly left the item (`!contains_focused`)
- skipped when modal is active (`!has_active_modal`)

### Impact

- Fixes missed autosaves when moving focus from item descendants to
other UI (terminal, file tree, search inputs, etc.).
- No behavior change for other autosave modes (`off`, `after_delay`,
`on_window_change`).

reliably work in multibuffers.

Replace the auto-generated `agent-[hash]` branch naming scheme with
names based on historical typewriter models (e.g. `olivetti-a3f9b2c1`,
`selectric-7d2e4f01`).

A static list of 49 typewriter names is used as the pool. When selecting
a name, existing branch names are checked—each branch is split on its
last `-` to extract the typewriter prefix, and any taken prefixes are
excluded from the candidate set. A random name is then picked from the
remaining candidates and suffixed with an 8-character alphanumeric hash.

The name selection logic accepts injected RNG and a list of disallowed
names, making it straightforward to test deterministically with
`#[gpui::test]` and `StdRng`.

I'm embedding a 3D viewport inside GPUI by creating a child window with
its own surface that fits the bounds of a GPUI element, and I need
access to the raw window handle of the current window to manage it.
Right now on X11 this is stubbed as unimplemented and results in a
panic. I've copied most of the same implementation from the associated
`RawWindow` into `X11Window`.

Small clip of a Bevy app embedded inside GPUI with a popover that draws
above the 3d surface to show testing was done:

Closes #47550

Changes the `auto_indent` setting from a boolean to an enum with three
modes:

- **`full`** (default): Adjusts indentation based on syntax context when
typing (previous `true` behavior)
- **`preserve_indent`**: Preserves the current line's indentation on new
lines, but doesn't adjust based on syntax
- **`none`**: No automatic indentation - new lines start at column 0
(previous `false` behavior)

This gives users more control over indentation behavior. Previously,
setting `auto_indent: false` would still preserve indentation on new
lines, which was unexpected.

Includes:
- Settings migration from boolean to enum values
- Settings UI dropdown renderer

Release Notes:

- Changed `auto_indent` setting from boolean to enum with `full`,
`preserve_indent`, and `none` options

Removes callouts like:
```markdown
> **Preview:** This feature is available in Zed Preview. It will be included in the next Stable release.
```

And:
```markdown
> **Changed in Preview (v0.XXX).** See [release notes](/releases#0.XXX).
```

These features are now in Stable, so the callouts are no longer needed.

Before this change the crash handler uploaded crashes before sign-in had
happened.

Now we get the metrics_id correctly. This allows for us to tie crashes
reported
on Github to users who have opted into telemetry (users who have opted
into
crash reporting but not telemetry will not have a metrics_id).

Release Notes:

- Fixed crash reporter metadata collection

This PR reworks how Zed calculates diff num stats by moving the
calculation to the `RepositorySnapshot` layer, instead of the
`GitPanel`. This has a couple of benefits:

1. Snapshot recalculations are already set up to recompute on file
system changes and only update the affected files. This means that diff
stats don't need to manage their own subscription or states anymore like
they did in the original PR.
2. We're able to further separate the data layer from the UI. Before,
the git panel owned all the subscriptions and tasks that refreshed the
diff stat, now the repository does, which is more inline with the code
base.
3. Integration tests are cleaner because `FakeRepository` can handle all
the data and calculations of diff stat and make it accessible to more
tests in the codebase. Because a lot of tests wouldn't initialize the
git panel when they used the git repository.
4. This made implementing remote/collab support for this feature
streamline. Remote clients wouldn't get the same buffer events as local
clients, so they wouldn't know that the diff stat state has been updated
and invalidate their data.
5. File system changes that happened outside of Zed now trigger the diff
stat refresh because we're using the `RepositorySnapshot`.

I added some integration tests as well to make sure collab support is
working this time. Finally, adding the initial diff calculation to
`compute_snapshot` didn't affect performance for me when checking
against chromium's diff with HEAD~1000. So this should be a safe change
to make.

I decided to add diff stats on the status entry struct because it made
updating changed paths and the collab database much simpler than having
two separate SumTrees. Also whenever the UI got a file's status it would
check its diff stat as well, so this change makes that code more
streamlined as well.

The empty bottom section of the project panel showed a horizontal

Add a `kernel_language_names` field to `LanguageConfig` that allows
languages to declare alternative names that Jupyter kernels may use.
This fixes REPL matching for cases where a kernel reports a different
language identifier than Zed's language name.

For example, the Nu extension would set `kernel_language_names =
["nushell", "nu"]` in its config.toml, enabling REPL support for
nu-jupyter-kernel which reports `"language": "nushell"` in its
kernelspec.

The change consolidates kernel language matching logic into a single
`Language::matches_kernel_language()` method that checks the code fence
block name, language name, and the new aliases list (all
case-insensitive).

The path hyperlink regex's middle-char pattern
[[:(][^0-9()]](cci:2://file:///d:/zed/crates/fs/src/fs.rs:89:0-157:1)
allowed colon+space because space was not in the exclusion set. This
caused `0: foo/bar.txt` to be matched as a single path instead of just
`foo/bar.txt`.

Fix: add space to the exclusion class: [[:(][^0-9()\\
]](cci:2://file:///d:/zed/crates/fs/src/fs.rs:89:0-157:1)

Gemini 3 Pro Preview has been deprecated in favor of Gemini 3.1 Pro.
This removes the `Gemini3Pro` variant from the `Model` enum and all

This PR cleans up the git command spawning by wrapping everything in
GitBinary instead to follow a builder/factory pattern. It also extends
trusted workspace support to git commands.

through `GitBinary`. This should help us maintain the factory pattern in
the future
