Release Notes:

- Improved error handling in the dev container crate to prevent panics

Before this change we'd spawn N tasks in parallel on every keystroke,
afterwards
we only allow 1 background diagnostic refresh in flight at a time.

This also fixed a bug where we'd send O(n*2) pull diagnostic requests
when
re-opening a workspace with n editors.

Closes #ISSUE

Release Notes:

- Improved performance when a large number of files were open by making
background diagnostics more efficient

This PR adds support for refreshing LLM tokens that are "outdated"—that
is, that are missing some required claims.

Release Notes:

- Fixed some instances of authentication errors with the Zed API that
could be resolved automatically by refreshing the token.

Closes #ISSUE

Release Notes:

- Fixed conda showing up in terminal windows

This PR adds a new `needs_llm_token_refresh` helper method for checking
if the LLM token needs to be refreshed.

We were duplicating the check for the `x-zed-expired-token` header in a
number of spots, and it will be gaining an additional case soon.

Closes #47503 

I added an observer for `GlobalTheme` changes that check if the accent
colors have changed or not. I thought this was closest to the patterns
and style in the codebase. I also considered triggering a
`SettingsStore` notification on theme reload but that seemed incorrect
since the settings didn't really change, even if it would solve the
problem (as the editor already observes `SettingsStore` to detect theme
changes.

Release Notes:

- Fixed Bracket color not updating when system theme changes

When a thread is interrupted while subagents are running, the subagent
cards now show a red X icon instead of a green checkmark. This provides
clearer visual feedback that the subagent was canceled rather than
completed successfully.

The icon logic now handles three states:
- **Spinner**: when status is Pending or InProgress
- **Red X**: when status is Canceled, Failed, or Rejected  
- **Green checkmark**: when status is Completed

This matches the existing pattern used elsewhere in the codebase for
showing error states on tool calls.

(No release notes because subagents are still behind a feature flag.)

Closes #47157

This panic happened because the editor was using `window.content_mask`
to get the visible bounds, which had a negative value for its height in
some cases.

This happened for three reasons:

1. `Bounds::from_corners` returns a negative size if callers pass in
corners where `bottom_right < top_left`. I originally wanted to add
error checking to this function but didn't, because it might be better
to move the error checking higher up. For now I'm going to push a fix
and figure out a better solution later

2. `Bounds::intersect` could return negative-sized bounds when the two
bounds didn't overlap, instead of returning a zero sized bounds.

3. `Style::paint` sometimes passed invalid corner values to
`Bounds::from_corners` (where the computed bottom-right was above/left
of the top-left).

Release Notes:

- editor: Fix a crash that could happen when editor visible line height
is zero

Release Notes:

- N/A

The rate limiter's semaphore guard was being held for the entire
duration of a turn, including during tool execution. This caused
deadlocks when subagents tried to acquire permits while parent requests
were waiting for them to complete.

## The Problem

In `run_turn_internal`, the stream (which contains the `RateLimitGuard`
holding the semaphore permit) was kept alive throughout the entire loop
iteration - including during **tool execution**:

1. Parent request acquires permit
2. Parent starts streaming, consumes response
3. Parent starts executing tools (subagents)
4. **Stream/guard still held** while tools execute
5. Subagents try to acquire permits → blocked because parent still holds
permit
6. Deadlock if all permits are held by parents waiting for subagent
children

## The Fix

Two changes were made:

1. **Drop the stream early**: Added an explicit `drop(events)` after the
stream is fully consumed but before tool execution begins. This releases
the rate limit permit so subagents can acquire it.

2. **Removed the `bypass_rate_limit` workaround**: Since the root cause
is now fixed, the bypass mechanism is no longer needed.

Note: no release notes because subagents are still feature-flagged, and
this rate limiting change isn't actually observable without them.

This PR updates the Git documentation to accurately reflect the current
UI and removes inaccuracies introduced in earlier drafts.

**Changes:**

- **Added Word Diff setting location**: The `word_diff_enabled` setting
is accessible in the Settings Editor under **Languages & Tools >
Miscellaneous**, which wasn't documented.

- **Simplified Remotes section**: Removed claims about command palette
actions for managing remotes that don't exist. The section now
accurately describes the remote selector in the Git Panel.

- **Added File History section**: Combined two paragraphs that said the
same thing.

This PR updates the Linux install script to support installing a
specific version of Zed via the
ZED_VERSION environment variable.

- If ZED_VERSION is set, that version will be downloaded.
- If ZED_VERSION is not set, the script defaults to the latest stable
version, preserving
  existing behavior.
- Works for both Linux and macOS installs.
- Maintains compatibility with ZED_CHANNEL for preview builds.

This enhancement allows users to:
- Pin a specific Zed version for reproducible setups or CI workflows.
- Easily install older or known-good versions without manually
downloading release assets.

Usage examples:
- Install latest stable (default):
  curl -f https://zed.dev/install.sh | sh
- Install specific version:
  curl -f https://zed.dev/install.sh | ZED_VERSION=0.216.0 sh
  
  Use this — it’s correct, concise, and clearly user-facing:

Release Notes

* **Added:** Support for installing a specific Zed version via the
`ZED_VERSION` environment variable in the install script (defaults to
`latest` when unset).

Users had trouble signing in due to us relying on the Copilot::global
being set, which was never the case. We've decided to use a dedicated
LSP instance just for handling auth of Copilot Chat and other goodies.
That instance is subscribed to by local Copilot instances for projects.
When the Auth instance changes it's state, local instances are prompted
to re-check their own sign in status.

Closes #47352

This PR fixes a crash in LoadingLabel where the loading animation
progressively revealed text by slicing with byte offsets (.len()), which
can panic for UTF-8 multi-byte characters (e.g., CJK) and emoji.

Release Notes:

- Fix a crash in LoadingLabel’s loading animation when displaying CJK or
emoji text.

Enables restoration of empty workspaces (without folders) that contain
unsaved items like drafts or single files. Empty workspaces are now
identified by workspace_id rather than paths, allowing multiple empty
workspaces to coexist and be properly restored on startup. This ensures
users don't lose work when closing Zed with unsaved files in empty
workspaces.

Closes #15098

Release Notes:

- Improved: Empty workspaces with unsaved files now restore on startup
(hot-exit)

Adds a new setting to GitHub Copilot to toggle the Next Edit Suggestions
feature, it is enabled by default.

## Motivations
Due to some current usability issues with this feature, see #46880, and
some personal anecdotes of using it, it is currently rough to utilize,
so this gives the option to disable it.

## Related
- #47071 
- #30124
- #44486
## Release Notes
- Adds the ability to disable GitHub Copilot's Next Edit Suggestions
feature.
## User Interface

![image](https://github.com/user-attachments/assets/5a3d7166-68dd-4f5b-a220-0a9bd9282cd5)
## Text Example
The text example will be adding a `z` variable to a `Point3D` class in
TypeScript.
### With Next Edit Suggestions
In this example I am able to just press auto-complete (press TAB) 3x.
```ts
class Point3D {
    x: number;
    y: number;
    z: number; // <-- Cursor before z: suggested

    constructor(x: number, 
                y: number
                , z: number // <-- Next Suggestion
                ) { 
        this.x = x;
        this.y = y;
        this.z = z; // <-- Last Suggestion
    }
}
```
### Without Next Edit Suggestions
```ts
class Point3D {
    x: number;
    y: number;
    z: number; // <-- Cursor before z: the only suggestion

    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}
```

Closes #46125.

Release Notes:

- acp: Add the ability to install new Agents via the ACP Registry

Release Notes:

- Improved @ file completions in agent panel to be more accurate

This is behind the beta flag. But some agents don't support a full load
flow, but rather just a resume from the current state of the session.
They don't emit notifications for past thread messages, which isn't
ideal, but the user can at least resume their work without completely
losing it.

We use it as a fallback if the agent doesn't support loading only, and
signal to the user that they won't be able to see previous messages.

Release Notes:

Closes https://github.com/zed-industries/zed/issues/47330

This PR moves the queue logic out of the native Thread into the shared
UI layer (thread view) to enable it for external agents. There's a key
difference in behavior, though, between native and external agents:
queued messages in the former will be sent in the next turn boundary,
given we can easily tell this, whereas for the latter, queued messages
will be sent by the end of the generation. We'd need an ACP-level change
to provide exactly the same UX between both types of agents, and I
figured that's better to have _some_ version of the feature for external
agents as opposed to not having it all due to this difference.

Release Notes:

- Agent: Made the message queue feature available for external agents as
well.

Closes #47309

Rewroked the file parsing loop so that if one file is missing it doesn't

config file was not present.

Release Notes:

Many editors such as vim and emacs support "modelines", a comment at the
beginning of the file that allows the file type to be explicitly
specified along with per-file specific settings

- The amount of configurations, style and settings mapping cannot be
handled in one go, so this opens up a lot of potential improvements.
- I left out the possiblity to have "zed" specific modelines for now,
but this could be potentially interesting.
- Mapping the mode or filetype to zed language names isn't obvious
either. We may want to make it configurable.

This is my first contribution to zed, be kind. I struggled a bit to find
the right place to add those settings. I use a similar approach as done
with editorconfig (merge_with_editorconfig). There might be better ways.

Closes #4762

Release Notes:

- Add basic emacs/vim modeline support.

Supersedes #41899, changes:
- limit reading to the first and last 1kb
- add documentation
- more variables handled
- add Arc around ModelineSettings to avoid extra cloning
- changed the way mode -> language mapping is done, thanks to
`modeline_aliases` language config
- drop vim ex: support
- made "Local Variables:" handling a separate commit, so we can drop it
easily
- various code style improvements

Closes #26866

### Summary
Adds a git graph to Zed, accessible via the `git_graph::Open` action if
a project has an active repository. There's still more to do, but this
is a solid foundation to expand upon. The code structure is in line with
Zed's codebase and shouldn't require architectural changes to add
missing features.

The git graph can be opened via the command palette (`git graph: open`)
or by binding a key to `git_graph::Open`. It's available when the
project has an active git repository.

### Architecture

Similar to the Debugger, the git graph is split between a data layer and
a view/UI layer. When the view layer is rendering, it queries the data
layer for its active state. This setup allows the data layer to lazily
request graph data (only when needed for rendering), abstracts collab
from the view layer, allows most of the data loading to happen on a
background thread, and makes caching easy to implement.

#### Graph Loading

The graph data is loaded in two phases:
1. `Repository::graph_data()` streams commit structure (SHA, parents,
refs) in chunks of 1000 via `git log`
2. `CommitDataReader` lazily fetches full commit details (author,
timestamp, subject) on-demand using a persistent `git cat-file --batch`
process

This two-phase approach makes the initial loading of the graph as fast
as possible, because `git log` takes significantly longer when all the
needed graph data is queried through it. Zed then lazily loads commits
in the user's viewport through `cat-file --batch`. This makes scrolling
to any place in the graph extremely snappy and benefits the
collaborative architecture by only fetching data needed to render the
graph. It also allows Zed to share commit data between different graph
visualizations (e.g., date order vs. topological order).

#### Performance

Tested on both the Zed and LLVM repositories with good performance in
both cases. The two-phase loading approach and lazy fetching keep the UI
responsive even with large commit histories.

#### Testing 

I added property testing that builds randomized commit graphs and
verifies that the graph is constructed correctly. This also works as an
integration test and will be expanded in the future to test collab graph
visualization, graph filtering, commit actions, etc.

### New Crate
- `git_graph` (GPL-licensed) — contains UI and graph computation logic

### Not Yet Implemented
- Remote repository support (collab)
- Filtering by branch
- Commit actions (checkout, cherry-pick, etc.)
- Search
- Open commit view for selected commit
- Resizable columns 
- Column filtering

Closes #46191

Release Notes:

- Make the auto signature popover — `"auto_signature_help": true` —
respect `hover_popover_delay`.

When committing, it was possible for the left-hand side multibuffer to
get the updated base text (via the `buffer_changed_since_sync`
mechanism) without updating its diff snapshot for that buffer (via the
diff subscription), causing a mismatch between that multibuffer's diff
state and its buffer state. The fix is to ensure for inverted diffs that
we always update pull an updated diff snapshot as part of
`sync_from_buffer_changes`.

This also removes some code that we added in #44838 to sync the
left-hand side multibuffer when edits on the right-hand side invalided
diff hunks. Instead, the left-hand side will just sync the next time the
diff recalculates when this happens, and will always consider hunks from
the last diff calculation as valid--so there will be a short window
where the diff transforms and `diff_hunks_in_range` don't match between
the two sides. That's okay because we don't rely on this in the display
map--the code that translates positions between the two sides accesses
the diff's `InternalDiffHunk`s directly rather than going through a
multibuffer API.

Previously we would create separate "Thinking" variants of the models
that supported thinking in the model selector.

This only applies to Anthropic models in the Zed provider, currently.

This is gated behind the `cloud-thinking-toggle` feature flag.
