as per its documentation:
`Async` supports all networking types, as well as some OS-specific file
descriptors like timerfd and inotify.
However, do not use `Async` with types like File, Stdin, Stdout, or
Stderr because all operating systems have issues with them when put in
non-blocking mode.

## Screenshot testing
Adds visual testing infrastructure for GPUI that captures screenshots by
rendering directly to Metal textures. The
The screenshots end up in `target/visual_tests/` and look like this:
<img width="2560" height="1600" alt="workspace_with_editor2"
src="https://github.com/user-attachments/assets/54112343-4af1-4347-9bab-f099de97dd29"
/>
<img width="2560" height="1600" alt="project_panel2"
src="https://github.com/user-attachments/assets/0cd54b61-dace-4398-a28e-0b4d7c2968f6"
/>
### Key Features
- **Direct texture capture**: Screenshots are captured by rendering the
scene to a Metal texture and reading pixels directly from GPU memory,
rather than using ScreenCaptureKit
- **No visibility requirements**: Windows don't need to be visible on
screen since we read directly from the render pipeline
- **Deterministic output**: Captures exactly what GPUI renders, not what
the OS compositor displays
- **No permissions needed**: Doesn't require Screen Recording permission
like ScreenCaptureKit would
### Running the Visual Tests
```bash
# Run visual tests (compares against baselines)
cargo run -p zed --bin visual_test_runner --features visual-tests
# Update baseline images (when UI intentionally changes)
UPDATE_BASELINE=1 cargo run -p zed --bin visual_test_runner --features visual-tests
# View the captured screenshots
open target/visual_tests/
```
### Implementation
- `Window::render_to_image()` - Renders the current scene to a texture
and returns an `RgbaImage`
- `MetalRenderer::render_to_image()` - Core implementation that renders
to a non-framebuffer-only texture
- `VisualTestAppContext` - Test context that uses real macOS platform
rendering
- `VisualTestAppContext::capture_screenshot()` - Synchronous screenshot
capture using direct texture rendering
### Usage
```rust
let mut cx = VisualTestAppContext::new();
let window = cx.open_window(...)?;
let screenshot: RgbaImage = cx.capture_screenshot(window.into())?;
```

### Why
Some more involved MCP servers timeout often, especially on first setup.
I got tired of having to set timeouts manually per server. I also
noticed a timeout could not be set for http context servers, which
causes Context7 or GitHub's remote servers to timeout at 60s sometimes.
### Overview
MCP Timeout Configuration Feature
This PR adds additional configurable timeout settings for Model Context
Protocol servers including a global timeout and the addition of timeouts
for http servers, addressing issues where servers were timing out after
a fixed 60 seconds regardless of user needs.
**Key Features:**
- **Global timeout setting** (`context_server_timeout`) - default
timeout for all MCP servers (default: 60s, max: 10min)
- **Per-server timeout overrides** - individual servers can specify
custom timeouts via `timeout` field
- **Precedence hierarchy** - per-server timeout > global timeout >
default (60s)
- **Automatic bounds checking** - enforces 10-minute maximum to prevent
resource exhaustion
- **Support for both transports** - works with stdio and HTTP-based
context servers
- **Comprehensive test coverage** - 3 new tests validating global,
override, and stdio timeout behavior
- **Full backward compatibility** - existing configurations work
unchanged with sensible defaults
### Release Notes:
- Added the ability to configure timeouts for context server tool calls.
The new global `context_server_timeout` setting controls the default
timeout (default is 60s, max: 10min). Additionally, per-server timeouts
can be configured using the `timeout` field within servers defined in
the `"context_servers" setting

Add support for OpenAI's /responses endpoint for models that don't
support /chat/completions API. This enables compatibility with newer
model variants (`gpt-5-codex`, `gpt-5-pro`, `o3-pro`, etc) while
maintaining compatibility with existing configs
Changes:
- Add `supports_chat_completions` flag to model capabilities that
defaults to true for existing behavior
- Implement responses API client with streaming support as per [OpenAI
documentation](https://app.stainless.com/api/spec/documented/openai/openapi.documented.yml).
- Add `ResponseEventMapper` to convert responses events to completion
events for maintainer simplicity
- Update UI to allow toggling `chat_completions` capability
- Add `gpt-5-codex` model
Closes#38858
Release Notes:
- Added support for `gpt-5-codex` model

Currently, the Python toolchain can identify `uv` and `uv-workspace`
environments (showing the correct labels in the UI), but it fails to
activate them when opening a new terminal. This is because the
activation script resolution and command generation logic were missing
for these environment kinds.
This PR adds `uv` and `uv-workspace` to the standard virtual environment
activation flow. Since `uv` creates environments with a standard `venv`
structure, we can reuse the existing `resolve_venv_activation_scripts`
logic to find and execute the appropriate `activate` scripts for
different shells.
Release Notes:
- Fixed terminal activation for `uv` and `uv-workspace` Python
environments.
## Problem
When clicking Stop button on a terminal tool call (or using terminal
kill bindings), only the shell process was killed. Child processes (like
`sleep`, `npm run`, etc.) continued running as orphans.
## Solution
On Unix, use `killpg()` instead of `sysinfo::Process::kill()` to
terminate the entire foreground process group.
`tcgetpgrp()` already returns the foreground process group ID, so
`killpg()` is the correct syscall to use here.
## Testing
1. Run a long command in terminal tool (e.g. `sleep 30`)
2. Click Stop button
3. Verify with `ps aux | grep sleep` that the process is actually killed
## Notes
- This fix is Unix-only (Linux, macOS)
- Windows behavior unchanged — may need separate investigation with Job
Objects
## Release Notes
- Fixed terminal Stop button not killing child processes on Unix (Linux,
macOS)

We use `block_with_timeout` to give the reparse task a millisecond to
complete, and if it takes longer we put the work off to the background.
The reason for this is that we want tree-sitter based features to feel
snappy.
The reparse task is non-cooperative though, it has no yield points,
giving us no place to actually check for our timeout, meaning we will
always drive it to completion and block for the entire duration.
This kicks out the `block_with_timeout` in favor of using the treesitter
progress callback to handle timeouts instead.
Release Notes:
- Improved responsiveness with very language language files on edits

The issue here was that we were missing a proper default for
`ThemeSelection`. This is a disadvantage of not having the defaults in
code but actually in the `default.json`, so this here basically copies
the default from the `default.json` into code for the settings UI to
work properly.
Release Notes:
- Fixed an issue where the theme was not configurable from the settings
UI if no theme was configured prior.

In https://github.com/zed-industries/zed/pull/44532 the syntax
highlighting of JS/TS was improved, but we only used `type.builtin` for
a specific case. This resulted in less consistent syntax highlighting.
Not all themes have this specific token and we don't use `type.builtin`
in other places either, so while this is a little less specific it is
more consistent.
Release Notes:
- Improved syntax highlighting consistency for builtins in JavaScript
and TypeScript
Closes#44904
Adds the Tailwind CSS LSP as suggested here:
https://github.com/zed-industries/zed/pull/39517#issuecomment-3368206678.
This allows users to use the Tailwind CSS LSP for CSS files, to support
Tailwind specific rules.
Docs will be added in a separate PR after this is released
Release Notes:
- Add Tailwind CSS Mode support, for Tailwind specific CSS rules like
`@apply`, `@layer`, and `@theme`.
When adding selections above/below with `skip_soft_wrap: true`, use
buffer column positions instead of pixel positions. This ensures
selections are placed at the same column offset in the buffer rather
than at the same visual position, which was incorrect for soft-wrapped
lines.
For example, selecting "how" in a wrapped line:
````
1. Very long line to
show [how] a wrapped
line would look
2. Very long line to
show how a wrapped
line would look
````
Now correctly adds a selection at the same buffer column in the next
line:
````
1. Very long line to
show [how] a wrapped
line would look
2. Very long line to
show [how] a wrapped
line would look
````
Closes#42137
Release Notes:
- Improved `editor: add selection above` and `editor: add selection
below` to select at the same text column when skipping soft-wrapped
lines, instead of the same visual position
Closes#39914
I was able to reproduce the issue on macOS using the same README.
The root cause was that `markdown_preview_view` attaches the image cache
to the root div, and while Div correctly applies that cache during
request_layout and paint, the prepaint phase didn’t have the same
context.
Markdown is rendered through a List, and `List::prepaint` renders its
items using `layout_as_root`. That meant images were getting loaded
during prepaint without the image cache in place. When that happened,
Img fell back to the global asset loader, which retains assets
indefinitely unless explicitly cleaned up.
So every image was loaded twice:
- once during layout/paint via RetainAllImageCache (correctly released
when the preview closed)
- once during prepaint via the global asset system (never released)
The result was doubled memory usage and a leak, since the globally
loaded images stuck around after the preview was closed.
Release Notes:
- Fixed a memory leak when previewing markdown files with images

Follow-up to #46001
That initial fix partly addressed the issue for diffs managed by the
`GitStore`, but not for other diffs (e.g. those managed by the
`ActionLog` or `CommitView`). The underlying issue is that we switched
to using a `Buffer` to represent the diff base text, and when updating
the diff we were calling `set_text` on this buffer and not waiting for
reparsing to finish. When the base text was represented by a series of
independent `BufferSnapshot`s, this wasn't an issue because we would
parse the base text in the background as part of computing the diff
update. This PR fixes the issue by waiting on reparsing to finish after
each call to `set_text`.
Release Notes:

This PR essentially removes the logic I introduced in
https://github.com/zed-industries/zed/pull/45361 to position workspace
modals based on the pointer click coordinates. All of this code has
become unnecessary given in
https://github.com/zed-industries/zed/pull/45924 we made the remote,
project, and branch modals use popovers when triggered with a pointer,
which already handle all the anchored positioning based on the trigger
(much better).
