Release Notes:

- Zed will no longer use `node` from your `$PATH` if it's older than
22.x (previously, the minimum version was 20.x). Instead, it will fall
back to its bundled `node`. This fixes being unable to use Copilot if an
older `node` was installed system-wide.

Closes #39144

Release Notes:

- python: Fixed user settings not being respected with Ty language
server.

This PR adds support for Grok 4 Fast.

After the change, we can add "supports_images", "supports_tools" and
"parallel_tool_calls" properties to set up new models. Our
`settings.json` will be as follows:
```json
  "language_models": {
     "x_ai": {
       "api_url": "https://api.x.ai/v1",
       "available_models": [
         {
           "name": "grok-4-fast-reasoning",
           "display_name": "Grok 4 Fast Reasoning",
           "max_tokens": 2000000,
           "max_output_tokens": 64000,
           "supports_tools": true,
           "parallel_tool_calls": true,
         },
         {
           "name": "grok-4-fast-non-reasoning",
           "display_name": "Grok 4 Fast Non-Reasoning",
           "max_tokens": 2000000,
           "max_output_tokens": 64000,
           "supports_images": true,
         }
       ]
     }
   }

```

Release Notes:

- xAI: Added support for for configuring tool and image support for
custom model configurations

This PR adds an `x-zed-client-supports-x-ai` header to the `GET /models`
request sent to Cloud to indicate that the client supports xAI models.

This PR fixes `x_ai::Model::from_id`, which was not properly handling
`grok-4`.

We've seen this panic come up in the last two weeks, which might be
caused by #33592. However, we are not sure what paths can cause this
`unwrap()` to fail. Therefore adding some logging around this, so that
the next time someone opens a bug report we can further diagnose the
issue.

Fixes ZED-1F6

Release Notes:

- Fixed an issue where Zed could crash when including specific paths in
a global `.gitignore` files

Closes #39112

Release Notes:

- Fixed an issue when using code actions on format where specifying
multiple code actions in the same code actions block that resolved to
code actions from different language servers could result in conflicting
edits being applied and mangled buffer text.

The bug happened because the Python locator was checking for a quote
before the ZED task variable. Removing that part of the check fixed the
issue.

Closes #39179 

Release Notes:

- Fix Python debug tasks not showing up in code actions or debug picker

- Closes #38847
- See also: #37622 and #38467

Release Notes:

- Fonts are now rendered in accordance with the `AppleFontSmoothing`
setting.

Before we would notify the user even if the download failed. We also
we're overwriting the directory, which means a user could be stuck in a
loop if a previous download failed

Release Notes:

- acp: Fix user seeing update prompt in a loop because of a previous
failed download

Closes #39139
Fixes ZED-1HY

Release Notes:

- Fixed a panic in UnwrapSyntaxNode in multi-buffers

Release Notes:

- Claude Sonnet 4.5 and 4.5 Thinking are now the recommended Anthropic
models

Release Notes:

- Added support for Claude Sonnet 4.5 for Bring-Your-Own-Key (BYOK)

Since we might run MCP servers locally for an agent, we don't want to
use the proxy for those.
We set this if the user has set a proxy, but not a custom NO_PROXY env
var.

Closes #38839

Release Notes:

- acp: Don't run local mcp servers through proxy, if set

Release Notes:

- Fixed potentially temporarily hanging on macOS when updating the app

This reverts commit 1bbf98aea6f335e791f19d8f76ba8a5f0510937f.

We found that #38411 caused problems where anonymous functions are
included too many times in the outline. We'd like to figure out a better
fix before shipping this to stable.

Fixes #38956

Release Notes:

- (preview only) revert changes to outline view

Closes #37601 

Regressed in https://github.com/zed-industries/zed/pull/36469. 

Edit: Original issue https://github.com/zed-industries/zed/issues/25744
is fixed for Zeta in this PR. For Copilot, it will be covered in a
follow-up. In the case of Copilot, even after discarding, we still get a
prediction on suggest, which is a bug.

Release Notes:

- Fixed issue where predict edit at cursor didn't work when
`show_edit_predictions` is `false`.

Closes #38553 
Release Notes:

- Fixed wrong AssetKind specified on linux for ty 


As discussed in the linked issue. All of the non windows assets for ty
are `tar.gz` files. This change applies that fix.

- Map path lookup and internal failures to acp::Error 
- Return INVALID_PARAMS for reads beyond EOF

Release Notes:

- acp: Return more informative error types from `read_text_file` to
agents

The previous validation was too strict and didn't permit reading empty
files.

Addresses: https://github.com/google-gemini/gemini-cli/issues/9280

Release Notes:

- acp: Fix `read_text_file` returning errors for empty files

Release Notes:

- N/A

Release Notes:

- Only allow single characters in the whitespace map

Fixes ZED-1K3

Release Notes:

generators)

The current problem is that if I specify model parameters, like
`max_tokens`, in `settings.json` for an Ollama model, they do not
override the values coming from the Ollama API. Instead, the parameters
from the API are used. For example, in the settings below, even though I
have overridden `max_tokens`, Zed will still use the API's default
`context_length` of 4k.

```
  "language_models": {
    "ollama": {
      "available_models": [
        {
          "name": "qwen3-coder:latest",
          "display_name": "Qwen 3 Coder",
          "max_tokens": 64000,
          "supports_tools": true,
          "keep_alive": "15m",
          "supports_thinking": false,
          "supports_images": false
        }
      ]
    }
  },
```

Release Notes:

- Fixed an issue where Ollama model parameters were not being correctly
overridden by user settings.

Previously, every piece of text in the agent panel was controlled by
`agent_font_size`. Although it is nice to only have one setting to tweak
that, it could be a bit misleading particularly because we use
monospaced and sans-serif fonts for different elements in the panel. Any
editor/textarea in the panel, whehter it is the main message editor or
the previous message editor, uses the buffer font. Therefore, I think it
is reasonable to expect that tweaking `buffer_font_size` would also
change the agent panel's usage of buffer fonts.

With this change, regular buffers and the agent panel's message editor
will always have the same size.

Release Notes:

- agent: Made the agent panel's textarea font size follow the font size
of regular buffers. They're now both controlled by the
`buffer_font_size` setting.

Address an issue where, in Vim mode, clicking past the end of a line
after selecting the entire line would place the cursor on the newline
character instead of the last character of the line, which is
inconsistent with Vim's normal mode expectations.

I believe the root cause was that the cursor’s position was updated to
the end of the line before the mode switch from Visual to Normal, at
which point `DisplayMap.clip_at_line_ends` was still set to `false`. As
a result, the cursor could end up in an invalid position for Normal
mode. The fix ensures that when switching between these two modes, and
if the selection is empty, the selection point is properly clipped,
preventing the cursor from being placed past the end of the line.

Related #38049 

Release Notes:

- Fixed issue in Vim mode where switching from any mode to normal mode
could end up with the cursor in the newline character
