When there's already a workspace that matches the paths provided,
activate that workspace, otherwise create a new window. This is
different from the default behavior of always adding to the sidebar.

$0.125 → $0.175
- Gemini 3 Flash: input $0.30 → $0.50, output $2.50 → $3.00

**Other fixes:**
- Student plan note updated to include GPT-5.4 pro restriction
- Grok context windows added to the context window table (128k / 256k
for Grok Code Fast 1)
- "GPT-5.2 Codex" renamed to "GPT-5.2-Codex" to match `display_name` in
code
- Removed retired "Gemini 3 Pro" from context window footnote

Release Notes:

- N/A

When filtering themes with a query that matches nothing (e.g., "zzz"),
`show_selected_theme` returned `None` and overwrote `selected_theme`.
Clearing the filter then lost track of the previous selection and
defaulted to index 0.

The fix only updates `selected_theme` when `show_selected_theme` returns
`Some`. Same change in both the theme selector and the icon theme
selector.

## Context

When `update_matches` runs a filter that yields zero results,
`show_selected_theme` returns `None`. The old code unconditionally
assigned that back to `selected_theme`, wiping out the previous
selection. When the user clears the filter, the selector falls into the
`query.is_empty() && selected_theme.is_none()` branch and resets to
index 0 instead of restoring the original pick.

## How to review

The fix is the same one-line change in two files:
1. `crates/theme_selector/src/theme_selector.rs` — line 458
2. `crates/theme_selector/src/icon_theme_selector.rs` — line 272

The rest is test infrastructure:
3. `crates/theme/src/registry.rs` — `register_test_themes` /
`register_test_icon_themes` helpers
4. Tests in both selector files covering the empty filter → clear filter
flow

## Release notes

- Fixed theme selector losing the selected theme after filtering with a
query that matches nothing and then clearing the filter.

Before, every creation of `AnchorSeekTarget` called
`MultiBufferSnapshot::buffer_for_path`, which seeks the excerpts sum
tree. Now we avoid that by

- looking up the buffer snapshot for the anchor's buffer in the
`buffers` map (keyed by `BufferId`)
- handling the case where the anchor's buffer doesn't exist at the
original path key with a separate `AnchorSeekTarget::Missing` variant

We also added a separate optimization to `AnchorSeekTarget::cmp`, to
skip the full `PathKey` comparison when the cursor's `PathKeyIndex` is
the same as the anchor's. This should help with singleton multibuffers.

Closes #39532

## Summary

Move the long-running agent "generating" spinner into a dedicated
`GeneratingSpinner` view.

Previously, the generating state rendered `SpinnerLabel` inline as part
of the full thread view. This change keeps the same spinner styling, but
isolates it into its own small view so the animation no longer needs to
live directly inside the larger thread UI subtree while the agent is
running.

Properly deserializes the app_port field, even if it is an array of
strings. Also, removes app_port from consideration when building a
docker-compose-based dev container, since the spec specifies that it
only applies to non-docker-compose dev containers.

Release Notes:

When a project mixes main repo worktrees (e.g. `extensions`) with linked
git worktrees (e.g. `zed4`, a linked worktree of `zed`), two things were
broken:

1. **Threads appeared under the wrong sidebar heading.** A thread
created in a workspace with both `extensions` and `zed4` would show
under the "zed" group instead of the "extensions, zed" group. This
happened because `main_worktree_paths` in `ThreadMetadata` was only
populated with paths from linked worktrees, omitting regular repos
entirely. The fix uses `project_group_key()` to normalize all visible
worktrees to their main repo paths — the same normalization the sidebar
uses for group headers.

2. **The worktree chip tooltip only showed linked worktree paths**,
missing main repo paths like `extensions`. This happened because
`worktree_info_from_thread_paths` filtered out main worktree paths
entirely. The fix introduces a `WorktreeKind` enum (`Main` / `Linked`)
on `ThreadItemWorktreeInfo`, so all worktrees are included in the data
model. Chips still only render for `Linked` worktrees (main worktrees
are redundant with the group header), but the tooltip now shows all
paths.

After chat functionality was removed, this panel became redundant. It
only displayed three notification types: incoming contact requests,
accepted contact requests, and channel invitations.

This PR moves those notifications into the collab experience by adding
toast popups and a badge count to the collab panel. It also removes the
notification-panel-specific settings, documentation, and Vim command.

Before you mark this PR as ready for review, make sure that you have:
- [ ] Added a solid test coverage and/or screenshots from doing manual
testing
- [x] Done a self-review taking into account security and performance
aspects
- [x] Aligned any UI changes with the [UI
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)

Release Notes:

- Removed the notification panel from Zed

Extend the DeploySearch action to accept additional parameters for
configuring the project search from keymaps:

- query: prefilled search query string
- regex: enable regex search mode
- case_sensitive: match case exactly
- whole_word: match whole words only
- include_ignored: search in gitignored files

With this change, the following keymap becomes possible:

```json
["pane::DeploySearch", { "query": "TODO|FIXME|NOTE|BUG|HACK|XXX|WARN", "regex": true }],
```

Release Notes:

- Added options to `pane::DeploySearch` for keymap-driven search
initiation

This PR improves the recent projects picker in the context of
multi-workspace:

- The currently active project now appears in the "This Window" section
with a checkmark indicator. Clicking it simply dismisses the picker,
since there's nothing to switch to. This feels like a better UX because
it gives you visual confirmation of where you are.
- The remove button is hidden for the current project entry, both in the
row and the footer, to prevent accidentally removing the workspace
you're actively using.
- The "Add to Workspace" button now uses a more descriptive icon
(`FolderOpenAdd`) and shows a meta tooltip clarifying that it adds the
project as a multi-root folder project.

The primary click/enter behavior remains unchanged—it opens the selected
project in the current window's multi-workspace. The "Open in New
Window" action continues to be available via the icon button or
shift+enter.

Release Notes:

- Improved the recent projects picker to show the currently active
project in the "This Window" section with a checkmark indicator.

- `language_model` no longer depends on provider-specific crates such as
`anthropic` and `open_ai` (inverted dependency)
- `language_model_core` was extracted from `language_model` which
contains the types for the provider-specific crates to convert to/from.
- `gpui::SharedString` has been extracted into its own crate (still
exposed by `gpui`), so `language_model_core` and provider API crates
don't have to depend on `gpui`.
- Removes some unnecessary `&'static str` | `SharedString` -> `String`
-> `SharedString` conversions across the codebase.
- Extracts the core logic of the cloud `LanguageModelProvider` into its
own crate with simpler dependencies.

I was testing out the changes in
https://github.com/zed-industries/zed/pull/52730 and realized that the
agent panel, when full screen, would be auto-dismissed if I toggled the
sidebar off. Turns out this happens because we were "hard-coding" the
focus back to the center pane, which was automatically dismissing zoomed
items. So, in this PR, I essentially am copying the ModalLayer approach
of storing whatever was focused before so we can return focus back to it
if possible.

Closes #50212

There are two unreasonable coupling account for this issue, the coupling
of `use_tree_sitter` with `languge_aware` in

https://github.com/zed-industries/zed/blob/7892b932795911516f26f3c1c1c72249ed181ba8/crates/editor/src/element.rs#L3820-L3822
and the coupling of `language_aware` with `diagnostics` in
https://github.com/zed-industries/zed/blob/7892b932795911516f26f3c1c1c72249ed181ba8/crates/language/src/buffer.rs#L3736-L3746

Because of these couplings, when the editor stops using Tree-sitter
highlighting when `"semantic_tokens"` set to `"full"`, it also
accidentally stops fetching diagnostic information. This is why error
and warning underlines disappear.

I’ve fixed this by adding a separate `use_tree_sitter` parameter to
`highlighted_chunks`. This way, we can keep `language_aware` true to get
the diagnostic data we need, but still decide whether or not to apply
Tree-sitter highlights. I chose to fix this at the `highlighted_chunks`
level because I’m worried that changing the logic in the deeper layers
of the DisplayMap or Buffer might have too many side effects that are
hard to predict. This approach feels like a safer way to solve the
problem.

Release Notes:

- Fixed a bug where diagnostic underlines disappeared when
"semantic_tokens" set to "full"

This PR fixes a mistake I pushed before of making the `ListItem`'s
height method take pixels instead of a scalable unit like rems. Now, it
takes `DefiniteLength` which can house both values, meaning we should be
clear to set an explicit height for all of these items while still
preserving font-size scaling.

This PR adds a configurable max-width to the agent panel. This will be
particularly useful when opting into an agentic-first layout where the
thread will be at the center of the UI (with the panel most likely
full-screen'ed, which is why I'm also adding here the button to make it
full screen in the toolbar). The default max-width is 850, which is a
bit bigger than the one generally considered as a standard (~66
characters wide, which usually sums up to 750 pixels).

Release Notes:

- Agent: Added a max-width to the thread view for better readability,
particularly when the panel is zoomed in.

## What This PR Does
This PR adds support for HTML alignment styles to be applied to
Paragraph and Heading elements and their children. Here is what this
looks like before vs after this PR (both images use the same markdown
below):

```markdown
<p style="text-align: center;">
  <a target="_blank" href="https://github.com/"><img width="150" height="150" src="https://upload.wikimedia.org/wikipedia/commons/c/c2/GitHub_Invertocat_Logo.svg"></a>

/>

## Notes
I used `style="text-align: center|left|right;"` instead of
`align="center|right|left"` since `align` has been [deprecated in
HTML5](https://www.w3.org/TR/2011/WD-html5-author-20110809/obsolete.html)
for block-level elements. The issue this PR solves mentioned that github
supports the `align="center|right|left"` attribute, so I'm unsure if the
Zed team would want to have parity there. Feel free to let me know if
that would be something that should be added, however for now I've
decided to follow the HTML5 standard.

Zeds impl of `%` didn't handle preprocessor directives and multiline

To implement this feature for multiline comment, a tree-sitter query is
used to check if we are inside a comment range
and then replicate the logic used in brackets.

For preprocessor directives using `TextObjects` wasn't a option, so it
was implemented through a text based query
that searches for the next preprocessor directives. Using text based
queries might not be the best for performance, so I'm open to any
suggestions.

- Fixed vim's matching '%' to handle multiline comments `/* */` and
preprocessor directives `#if #else #endif`.

Closes #48007 

Release Notes:

- Added editor setting for changing regex mode default in vim searches

Summary:

- Based on the report in #48007 and the discussion here
https://github.com/zed-industries/zed/pull/48127#issuecomment-3838678903
- There was feedback mentioning that vim-mode needs to default
vim-searches to use regex-mode (even when the editor regex-search
setting is disabled). However, it was suggested that a vim search
setting could be configured to adjust this behaviour.
- In this PR a new vim setting was added to change whether vim-searches
will use regex-mode by default, so now users can can configure
vim-search to not use regex-mode when typing the `/` character (or using
the vim search command).

Closes #53115

Release Notes:

- Fixed terminal cursor blink not resetting when navigating with
action-bound keys (e.g., alt+left/right on macOS, alt+b/f on Linux)

## Demo

### Before the fix
The cursor stays invisible after word-jumping because the blink cycle
keeps going without resetting.

### After the fix
The cursor shows up at the new position right after each word-jump, then
blinks again as expected.

Closes #52239

## Summary

Note - The code in this fix is AI generated.

OpenCode ACP chats lost slash-command support after Zed restarted and a
thread was reopened. The UI no longer showed `/ for commands`, and slash
commands like `/help` were treated as unsupported.

## Root Cause

ACP available commands were treated as transient UI state instead of
durable thread state.

- `AcpThread` handled `AvailableCommandsUpdate` but did not retain the
commands on the thread
- restored thread views rebuilt `SessionCapabilities` with an empty
`available_commands` list
- the message-editor placeholder started in the wrong state for restored
threads
- live command updates could be applied to the wrong thread view

## Fix

- persisted `available_commands` on `AcpThread`
- restored `SessionCapabilities` from thread state
- reused the same command augmentation logic for restore and live update
paths
- updated live command handling to target the correct thread view
- initialized the message-editor placeholder from current command
availability
- added a regression test for the restore path

## Verification

- `cargo test -p agent_ui
conversation_view::tests::test_restored_threads_keep_available_commands
-- --exact --nocapture`
- `./script/clippy -p agent_ui --tests`

Release Notes:

- Fixed ACP slash commands disappearing after reopening restored
threads.

Extend the git API with several new capabilities needed for worktree
archival and restoration:

- Add `allow_empty` flag to `CommitOptions` for creating WIP marker
commits
- Change `create_worktree` to accept `Option<String>` branch, enabling
detached worktree creation when `None` is passed
- Add `head_sha()` to read the current HEAD commit hash
- Add `update_ref()` and `delete_ref()` for managing git references
- Add `stage_all_including_untracked()` to stage everything before a WIP
commit
- Implement all new operations in `FakeGitRepository` with functional
commit history tracking, reset support, and ref management
- Update existing call sites for the new `CommitOptions` field and
`create_worktree` signature

Part 1 of 3 in the persist-worktree stack. These are nonbreaking API
additions with no behavioral changes to existing code.

Closes https://github.com/zed-industries/zed/issues/53159

Recently, we changed the behavior of pickers so that hovering matches
would also select them. This makes sense for most pickers that are used
as "regular" pickers, but we have some in Zed that are not. A great
example of one is the rules library, which sort of became way less
usable with this behavior. So, this PR introduces a simple bool trait
method to the picker so that we can turn this behavior off whenever
necessary. The rules library kicks off as the only instance of it being
turned off.

Release Notes:

- Fix navigation within the rules library making it so hovering the
sidebar doesn't activate the visible rule.

When `tab_bar.show_pinned_tabs_in_separate_row` is enabled,
double-clicking the empty space on the unpinned tab row creates a new
tab, but double-clicking the empty space on the pinned tab row does
nothing.

Add the same `on_click` double-click handler to the pinned tab bar drop
target so both rows behave consistently.

Release Notes:

- Fixed double-clicking empty space in the pinned tab row not opening a
new tab when `show_pinned_tabs_in_separate_row` is enabled.

- Fix an issue where the "remove project" button, available in the
header's ellipsis menu, wouldn't do anything if the sidebar contained
only one project
- Fix another issue where attempting to remove a project when the
sidebar has more than one project wouldn't actually remove it. This is
fixed by cleaning up the project group keys after its been already
removed.
