for unknown reasons.

Temporarily suspend them.

Example failing builds:
- [2025-07-15 16:15 Nightly
Failure](https://github.com/zed-industries/zed/actions/runs/16302777887/job/46042358675)
- [2025-07-15 12:20 Nightly
Success](https://github.com/zed-industries/zed/actions/runs/16297907892/job/46025281518)

- [2025-06-17 Nightly
Failure](https://github.com/zed-industries/zed/actions/runs/15700462603/job/44234573761)

Release Notes:

- Temporarily disable FreeBSD zed-remote-server builds due to CI failures.

Release Notes:

- Add zed://extension/{id} links to open the extensions UI with a
specific extension

Closes #30010

Release Notes:

- Add support for xAI language model provider

Closes #34044

`EditorMode::SingleLine { auto_width: true }` was only used for the
title editor in the rules library, and following
https://github.com/zed-industries/zed/pull/31994 we can replace that
with a normal single-line editor without problems. The auto-width editor
was interacting badly with the recently-added newline visualization
code, causing a panic during layout---by switching it to
`Editor::single_line` the newline visualization works there too.

Release Notes:

- Fixed a panic that could occur when opening the rules library.

Cherry-picked debugger: Fix endless restarts when connecting to TCP
adapters over SSH (#34328)

Closes #34323
Closes #34313

The previous PR #33932 introduced a way to "close" the
`pending_requests` buffer of the `TransportDelegate`, preventing any
more requests from being added. This prevents pending requests from
accumulating without ever being drained during the shutdown sequence;
without it, some of our tests hang at this point (due to using a
single-threaded executor).

The bug occurred because we were closing `pending_requests` whenever we
detected the server side of the transport shut down, and this closed
state stuck around and interfered with the retry logic for SSH+TCP
adapter connections.

This PR fixes the bug by only closing `pending_requests` on session
shutdown, and adds a regression test covering the SSH retry logic.

Release Notes:

- debugger: Fixed a bug causing SSH connections to some adapters
(Python, Go, JavaScript) to fail and restart endlessly.

Cherry-picked language_models: Refresh the list of models when the LLM
token is refreshed (#34222)

This PR makes it so we refresh the list of models whenever the LLM token
is refreshed.

token.

Release Notes:

- Fixed model list not refreshing when subscribing to Zed Pro.

When [`drag_and_drop_selection` is
true](https://zed.dev/docs/configuring-zed#drag-and-drop-selection),
users can make a selection in the buffer and then drag and drop it to a
new location. However, the editor forces users to wait 300ms after mouse
down before dragging. If users try to drag before this delay has
elapsed, they will create a new text selection instead, which can create
the impression that drag and drop does not work.

I made two changes to improve the UX of this feature:

* If users do not want a delay before drag and drop is enabled, they can
set the `drag_and_drop_selection.delay_ms` setting to 0.
* If the user has done a mouse down on a text selection, the cursor
changes to a copy affordance as soon as the configured delay has
elapsed, rather than waiting for them to start dragging. This way they
don't need to guess at when the delay has elapsed.

The default settings for this feature are now:

```
"drag_and_drop_selection": {
  "enabled": true,
  "delay_ms": 300
}
```

Closes #33915

- Migrate `drag_and_drop_selection` setting to
`drag_and_drop_selection.enabled`.
- Add `drag_and_drop_selection.delay_ms` setting to configure the delay
that must elapse before drag and drop is allowed.
- Show a ready to drag cursor affordance as soon as the delay has
elapsed

This Pull Request introduces various changes to the editor's horizontal
scrolling, mostly focused on vim mode's horizontal scroll motions (`z
l`, `z h`, `z shift-l`, `z shift-h`). In order to make it easier to
review, the logical changes have been split into different sections.

## Cursor Position Update

Changes introduced on https://github.com/zed-industries/zed/pull/32558
added both `z l` and `z h` to vim mode but it only scrolled the editor's
content, without changing the cursor position. This doesn't reflect the
actual behavior of those motions in vim, so these two commits tackled
that, ensuring that the cursor position is updated, only when the cursor
is on the left or right edges of the editor:

-
https://github.com/zed-industries/zed/commit/ea3b866a763ba0bcfc12999ee1741c6528c895b7
-
https://github.com/zed-industries/zed/commit/805f41a913c6e86ef8be550d363a3cc2caeccbe9

## Horizontal Autoscroll Fix

After introducing the cursor position update to both `z l` and `z h` it
was noted that there was a bug with using `z l`, followed by `0` and
then `z l` again, as on the second use `z l` the cursor would not be
updated. This would only happen on the first line in the editor, and it
was concluded that it was because the
`editor::scroll::autoscroll::Editor.autoscroll_horizontally` method was
directly updating the scroll manager's anchor offset, instead of using
the `editor::scroll::Editor.set_scroll_position_internal` method, like
is being done by the vertical autoscroll
(`editor::scroll::autoscroll::Editor.autoscroll_vertically`).

This wouldn't update the scroll manager's anchor, which would still
think it was at `(0, 1)` so the cursor position would not be updated.
The changes in [this
commit](https://github.com/zed-industries/zed/commit/3957f02e189018ef559cd28516f0b872026b0ce1)
updated the horizontal autoscrolling method to also leverage
`set_scroll_position_internal`.

## Visible Column Count & Page Width Scroll Amount

The changes in
https://github.com/zed-industries/zed/commit/d83652c3ae1d0356fd7dca7b8922a0116de39ff0
add a `visible_column_count` field to `editor::scroll::ScrollManager`
struct, which allowed the introduction of the `ScrollAmount::PageWidth`
enum.

With these changes, two new actions are introduced,
`vim::normal::scroll::HalfPageRight` and
`vim::normal::scroll::HalfPageLeft` (in
https://github.com/zed-industries/zed/commit/7f344304d56337654a34b1b461a1dc69defd2e4e),
which move the editor half page to the right and half page to the left,
as well as the cursor position, which have also been mapped to `z
shift-l` and `z shift-h`, respectively.

Closes #17219 

Release Notes:

- Improved `z l` and `z h` to actually move the cursor position, similar
to vim's behavior
- Added `z shift-l` and `z shift-h` to scroll half of the page width's
to the right or to the left, respectively

This PR adds a new `zed-cloud` feature flag that can be used to send
traffic to `cloud.zed.dev` instead of `llm.zed.dev`.

This is just so Zed staff can test the new infrastructure. When we're
ready for prime-time we'll reroute traffic on the server.

This disables word based completions in Plain Text and Markdown buffers
by default.

Word-based completion when typing natural language can be quite
disruptive, in particular at the end of a line (e.g. markdown style
lists) where `enter` will accept word completions rather than insert a
newline (see screenshot). I think the default, empty buffer experience
in Zed should be closer to a zed-mode experience -- just an editor
getting out of your way to let you type and not having to mash
escape/cmd-z repeatedly to undo a over-aggressive completion.

- Context:
https://github.com/zed-industries/zed/issues/4957#issuecomment-3049513501
- Follow-up to: https://github.com/zed-industries/zed/pull/26410

Re-enable the existing behavior with:
```json
  "languages": {
    "Plain Text": { "completions": { "words": "fallback" } },
    "Markdown": { "completions": { "words": "fallback" } },
  },
```
Or disable Word based completions everywhere with:
```json
  "completions": { 
    "words": "fallback"
  },
```

Release Notes:

- Disable word-completions by default in Plain Text and Markdown Buffers

Might close #33838 for now

Keymaps that work both in vim and helix, but only in normal mode, not
the more general `VimControl` context are written separately. This makes

Release Notes:

- Fix bug where spawning a Zed generated task or debug session with Fish
or Nushell failed

Closes #19892

Things like borders, border colors, which icons are being used, button
sizes, and spacing. There is more to do here: polish that we're using a
bunch of divs for spacing, arbitrary pixel values for tokens we have in
the system, etc. This is just a quick pass!

Release Notes:

- git panel: Polished the panel spacing, border colors, and icons.

Trying to delete a user record from our admin panel throws the following
error:

`update or delete on table "users" violates foreign key constraint
"access_tokens_user_id_fkey" on table "access_tokens"
Detail: Key (id)=(....) is still referenced from table "access_tokens".`

We need to add a cascade delete to the `access_tokens` table.

Similar to https://github.com/zed-industries/zed/pull/34040, this PR
allows to control via settings whether the terminal card in the agent
panel should be expanded. It is set to true by default.

Release Notes:

- agent: Added a setting to control whether terminal cards are expanded
in the agent panel, thus showing or hiding the full command output.

Closes #32673

Release Notes:

- Fixed diagnostic popovers not being scrollable

Follow up: https://github.com/zed-industries/zed/pull/34042

- Removes `top_slot_items` from `uniform_list` in favor of using
existing `decorations`
- Add condition to only show shadow for sticky item when list is
scrolled and scrollable

Release Notes:

This PR adds the `expand_edit_card` setting, which controls whether edit
cards in the agent panel are expanded, thus showing or not the full diff
of a given file's AI-driven change. I personally prefer to have these
cards collapsed by default as I am mostly reviewing diffs using either
the review multibuffer or the diffs within the file's buffer itself.
Didn't want to change the default behavior as that was intentionally
chosen, so here we are! :)

Open to feedback about the setting name; I've iterated between a few
options and don't necessarily feel like the current one is the best.

Release Notes:

- agent: Added a setting to control whether edit cards are expanded in
the agent panel, thus showing or hiding the full diff of a file's
changes.

Just a small quality-of-life type of PR that makes clicking anywhere
until the "Review" button trigger the action that that button triggers
(i.e., opens the review multibuffer).

<img

width="600" />

Release Notes:

- agent: Added the ability to click the whole file row in the edits bar
to trigger the review multibuffer.

Follow-up to https://github.com/zed-industries/zed/pull/33994. This PR
adds a subtle shadow—built from an absolute-positioned div, due to
layering of items—to the last sticky item in the project panel when that
setting is turned on. This helps understand the block of items that is
currently sticky.

<img

width="300"/>

Would love to add indent guides to the items that are sticky as a next
step.

Release Notes:

- project panel: When `sticky_scroll` is true, the last item will now
have a subtle shadow to help visualizing the block of items that are
currently sticky.

This commit removes the PHP debug adapter in favor of a new version
(0.3.0) of PHP extension.
The name of a debug adapter has been changed from "PHP" to "Xdebug",
which makes this a breaking change in user-configured scenarios

Release Notes:

- debugger: PHP debug adapter is no longer shipped in core Zed editor;
it is now available in PHP extension (starting with version 0.3.0). The
adapter has been renamed from `PHP` to `Xdebug`, which might break your
user-defined debug scenarios.

- **debugger: Move cacheable property onto LocalDapCommand**
- **debugger/session: Relax method bounds to use LocalDapCommand**


Release Notes:

- N/A

Closes #33253 in a way that doesn't regress #32175 - namely,
automatically adjusts the contrast between the foreground and background
text in the terminal such that it's above a certain threshold. The
threshold is configurable in settings, and can be set to 0 to turn off
this feature and use exactly the colors the theme specifies even if they
are illegible.

## One Light Theme Before
<img width="220" alt="Screenshot 2025-07-07 at 6 00 47 PM"

/>

(Last row is highlighted because otherwise the text is unreadable; the
foreground and background are the same color.)

## One Light Theme After

(This is with the new default contrast adjustment setting.)

/>

This approach was inspired by @mitchellh's use of automatic contrast
adjustment in [Ghostty](https://ghostty.org/) - thanks, Mitchell! The
main difference is that we're using APCA's formula instead of WCAG for
[these
reasons](https://khan-tw.medium.com/wcag2-are-you-still-using-it-ui-contrast-visibility-standard-readability-contrast-f34eb73e89ee).

Release Notes:

- Added automatic dynamic contrast adjustment for terminal foreground
and background colors
