Coming from discussion on #25936 and
https://github.com/zed-industries/zed/pull/19756 .
This PR introduces the KernelSession abstraction and adds basic notebook
cell execution inside NotebookEditor.
The following provides a base starter for the development on Notebooks.
What this PR includes today:
Release Notes:
- KernelSession trait extracted. Both REPL and NotebookEditor now share
the same routing mechanism.
- NotebookEditor can launch kernels, execute code cells, and display
outputs.
- Basic cell operations: run current cell, run all, move up/down, add
code/markdown blocks. Keybindings follow Jupyter defaults.
Next Steps:
- [x] Editing support for markdown and code blocks.
- Buffer integration instead of temporary cell text.
- [x] Proper focus behavior when executing or adding cells.
- Kernel control UI.
A little far fetched steps:
- Vim Support
- Cell Handling Improvement and other convenient features and design
from other editors
- Ability to have better parsing for AI Support.
I have attached a video of showcasing some of the features:

Closes https://github.com/zed-industries/zed/issues/47347
Release Notes:
- Agent: Fixed a bug where the inline assistant feedback buttons where
being displayed despite the setting "Enable Feedback" was turned off.
Closes#45994
Per the JSON-RPC specification, `params` "MUST be provided as a
Structured value" or the member "MAY be omitted." See specification
here: https://www.jsonrpc.org/specification#request_object
The code was passing in unit `()` for params which serde_json was
serializing to `null` which is not valid.
This pulls request adds an `is_unit` function and annotates the `params`
fields in the `Request` and `Notification` structs with the following:
```rs
#[serde(default, skip_serializing_if = "is_unit")]
```
so that the field will be omitted if the type is unit. This does also introduce a `'static` bound to these structs.
> [!WARNING]
> While this seems to me like a simple change, I am not super familiar with Rust, please look at this PR with extra scrutiny. The last thing I want to do is break everyone's LSP integration.
Release Notes:
- LSP integrations: send language server shutdown requests with correct parameters
Some users were a bit confused that the history between zed agent + text
threads is split up now. Making it a bit clearer for the users still
using text threads which history they are currently looking at.

Before we were checking it even if you weren't using registry agents.
Now happens less frfrequently, and only when you are actually using
registry agents.

modal stays open)
This issue has been driving me insane haha.

kind and let me know if I have missed something. I tested this fix on my
machine and it works. Tests are passing on my device. I have agreed to

## Summary
Implements user-defined slash commands for the agent panel. Users can
create markdown files in `~/.config/zed/commands/` (user-wide) or
`.zed/commands/` (project-specific) that expand into templated text when
invoked via `/command_name` in the chat interface.
## Features
- **File-based commands**: Create `.md` files that become slash commands
- **Template expansion**: Use `$1`, `$2`, etc. for positional arguments,
or `$ARGUMENTS` for all args
- **Namespacing**: Subdirectories create namespaced commands (e.g.,
`frontend/component.md` → `/frontend:component`)
- **Project & user scopes**: Project commands in `.zed/commands/`, user
commands in config dir
- **Claude compatibility**: Can symlink `~/.claude/commands/` for
compatibility
- **Caching**: Commands are cached and watched for file changes
- **Error handling**: Graceful degradation with error display in UI
## Feature Flag
Behind `user-slash-commands` feature flag.
## Testing
52 unit/integration tests covering parsing, validation, expansion, file
loading, symlinks, and error handling.

This is in preparation for removing one of the files in favor of having
just one larger one (and perhaps renaming that in the future).
Release Notes:
- N/A
Previously, when project search results first appeared, vim would
incorrectly switch to Visual mode. This happened because vim settings
(including `collapse_matches`) weren't synced to an editor until it
received focus. Since the results editor wasn't focused when the first
match was selected, the selection wasn't collapsed, causing vim to
interpret it as a visual selection.
Now vim settings are synced immediately when vim activates on an editor,
ensuring `collapse_matches` is set before any selections are made.
Closes#43878
Release Notes:
- Fixed vim mode incorrectly switching to Visual mode on first project
search

The last extension has now been migrated to the new workflows and with
that, the entire zed-extensions org now uses the centralized workflows 🎉
Given this, we can now remove the exclusion list and - as a little bonus
- also rollout changes automatically to the repository hosting the
shared workflows.
Release Notes:
- N/A
Closes#40648
When deleting a prompt from the rules library, we now also delete it
from the legacy V1 database tables (if they exist). Previously, the V1
data would persist and get re-migrated on the next startup.
Release Notes:
- Fixed an issue where deleted rules from the rules library were getting
restored after a restart.
Closes #ISSUE
We're hitting request size limits on the new larger dataset, so we need
to do pre-batching. A 16k chunk size was chosen arbitrarily but seems to
be a good tradeoff between number of chunks / within request size limit

This PR removes the `open-ai-responses-api` feature flag and makes it so
all OpenAI requests to the Zed provider use the Responses API.
We've been running this in Nightly/Preview for a week now without any
issues.
Closes CLO-104.

Closes#47307
In markdown, the outline item for a heading actually ends on the same
row as the next outline item (see #47307 for the visual glitch). This
change makes it so that the end row calculation accounts for that, and
you don't have two different display points where content is potentially
scrolling out of view. Fixed visually:
https://github.com/user-attachments/assets/e0a7e57a-fd41-4484-87e9-ac3e51d0b927
Release Notes:
- Fixed a visual glitch with sticky scroll headers in markdown
This PR improves the performance of the `CopyButton` component by
tracking the copied state locally through a `CopyButtonState` struct
instead of making an OS call every time the component re-renders. Also
pushing a slight improvement here by resetting the state after two
seconds so as to make the check mark go away after you clicked to copy.

Fixes CI failures when the target dir is 0GB in size, which causes
`expr` to output a non-zero exit code per the posix spec.
See exit status section of
https://www.man7.org/linux/man-pages/man1/expr.1p.html
Release Notes:
- N/A *or* Added/Fixed/Improved ...
- Improves spacing between consecutive calls
- Only show disclosure button (i.e., ability to expand the card) when
there's actual content
- Fix font size being bigger than the actual thread
- Add gradient overlay to communicate that you can't scroll within the
card (expanding the subagent call will allow that in the near future)
Here's the result of it all, roughly:

The cyan terminal colors in One Light were incorrectly set to the same
values as green, making them indistinguishable. This was introduced in
https://github.com/zed-industries/zed/pull/44912
Release Notes:
- Fixed terminal cyan color displaying as green in One Light theme
Closes#47098
The root cause of this issue is related to how `Poetry` (and the
upstream `pet-poetry` library) handles path hashing. While perhaps it's
an upstream behavior, we can easily fix it on the Zed side.
The related code are
https://github.com/zed-industries/zed/blob/23c7d60f1e9a1f9e4ce1502aad3bf90c8093833e/crates/languages/src/python.rs#L1181-L1211
In my debugging, I found that `worktree_root` takes the form
`/home/user/project`, but `config.workspace_directories` often ends up
as `/home/user/project/`(with a trailing slash). Normally this wouldn't
be an issue, but `Poetry` generates environment names based on the hash
of the absolute path. Since the hashes for `/home/user/project` and
`/home/user/project/` are different, `pet-poetry` fails to find the
environment.
The fix is straightforward: we just need to ensure the trailing `/` is
removed so the hashes match.
Release Notes:
- Fixed poetry environment not discovered on linux
Fixes an unintended behavioral change from #40838.
Release Notes:
- Fixed "Add Folder to Project" and "Remove from Project" menu items
being incorrectly hidden on remote projects.
The settings store separate themes for Light and Dark modes. When the
user clicks a theme, the code uses the system appearance to decide which
to update, rather than the mode the user selected in the UI. This causes
the wrong theme to be saved when the system appearance differs from the
selected mode.
