#37622 was incorrectly forcing font smoothing to be enabled on macos
even when the user had disabled that setting at the OS level. See [this
comment](https://github.com/zed-industries/zed/pull/37622#issuecomment-3310030659)
for an example of the difference that font smoothing makes.

Release Notes:

- N/A

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

Not an ideal fix, but a proper one will require restructuring the

Closes https://github.com/zed-industries/zed/issues/38547

Release Notes:

- Reverted the ability to show/hide the titlebar. This caused rendering
bugs on
macOS, and we're preparing for the redesign which requires the toolbar
being present.

Closes #38651 

`git_panel.set_amend_pending(false, cx);` was being called before
`git_panel.commit_changes(...)` which was causing the commit buffer to
be cleared/reset before actually sending the commit request to git.

Introduced by #35268 which added clear buffer functionality to the
`set_amend_pending` function.

Release Notes:

- Fix git amend on panel sending "Update ..." instead of the original
commit message
- FIx git amend button not working

Solves an issue where Google APIs refuse all requests with file-based
tool calls attached.
This seems to get triggered in the case where:

- copy_path + another file-based tool call is enabled
- default terminal is `/bin/bash` or something similar

It is unclear why this is happening, but removing the terminal commands
in those tool calls seems to have solved the issue.

Closes #37180 and #37414

Release Notes:

- agent: Fix Gemini refusing requests with certain profiles/systems.

This PR updates the Gemini provider to treat a
`prompt_feedback.block_reason` as a refusal, as Gemini does not seem to
return a `stop_reason` to use in this case.

/>

Previously this would just result in no feedback to the user.

Release Notes:

- Added an error message when a Gemini response contains a
`block_reason`.

In cffb883108ec07ec2f51446cb35eac19b89e625f I put the fixed keybindings
on the wrong platform

Release Notes:

- Fix syntax node shortcuts

Release Notes:

- Fixed an issue where expand toggles were too large with the git blame
deployed.

This PR updates the version range for v0.6.0 of the extension API to
include v0.7.0.

Since we bumped the `zed_extension_api` crate's version to v0.7.0, we
need to expand this range in order for Zed clients to be able to install
extensions built against v0.7.0 of `zed_extension_api`.

Currently no extensions that target `zed_extension_api@0.7.0` can be
installed.

Release Notes:

- N/A

Reverts #38175, which is not correct, since in fact we do need to
pre-quote the command and arguments for the shell when using
`SpawnInTerminal` (although we should probably change the API so that
this isn't necessary). Then, applies the same fix as #38565 to fix the
root cause of being unable to spawn the login task on macOS, or in any
case where the command/args contain spaces.

Release Notes:

- Fixed being unable to login with Claude Code or Gemini using the
terminal.

Release Notes:

Closes #38347

Release Notes:

- Fixed path and args to ty lsp binary


When attempting to use the new ty lsp integration in the preview, I
noticed issues related to accessing the binary. After deleting the
downloaded archive and adding the following changes that:

- downloads the archive with the correct `AssetKind::TarGz`
- uses the correct path to the extracted binary
- adds the `server` argument to initialize the lsp (like ruff)

After the above changes the LSP starts correctly
```bash
2025-09-18T16:17:03-05:00 INFO  [lsp] starting language server process. binary path: "/Users/dereknguyen/Library/Application Support/Zed/languages/ty/ty-0.0.1-alpha.20/ty-aarch64-apple-darwin/ty", working directory: "/Users/dereknguyen/projects/test-project", args: ["server"]

Closes #ISSUE

In local projects, initialize the list of agents in the agent server
store immediately. Previously we were initializing the list only after a
delay, in an attempt to avoid sending the `ExternalAgentsUpdated`
message to the downstream client (if any) before its handlers were
initialized. But we already have a separate codepath for that situation,
in the `AgentServerStore::shared`, and we can insert the delay in that
place instead.

Release Notes:

- acp: Fixed a bug where starting an external agent thread soon after
Zed starts up would show a "not registered" error.

Potential fix for #38377 

Release Notes:

Co-authored-by: Peter Tripp <petertripp@gmail.com>

This panic only happened in debug builds because of a left shift
overflow. The slice range has bounds between 0 and 128. The 128 case
caused the overflow.

We now do an unbounded shift and a wrapped sub to get the correct
bitmask. If the slice range is 128 left, it should make 1 zero. Then the
wrapped sub would flip all bits, which is expected behavior.

This reverts commit 4002602a8926b7fe799acf50fcee6bcffb36d376.

We were incorrectly handling the line number as well as stripping out
line breaks when returning portions of files.

It also makes sure following is updated even when we load a snapshot
from cache, which wasn't the case before.

We also are able to load the text via a range in the snapshot, rather
than allocating a string for the entire file and then another after
iterating over lines in the file.

Release Notes:

- acp: Fix incorrect behavior when ACP agents requested to read portions
of files.

Bug in https://github.com/zed-industries/zed/pull/32927

Instead of using trigger characters to clear cached completions items,
now we check if the query is empty to clear it. Turns out Emmet defines
whole [alphanumeric as trigger
characters](https://github.com/olrtg/emmet-language-server/blob/279be108725fb391c167690b697ce154fd32657b/index.ts#L116)
which causes flickering.

Clear on trigger characters was introduced to get rid of cached
completions like in the case of "Parent.Foo.Bar", where "." is one of
the trigger characters. This works still since "." is not part of
`completion_query_characters` and hence we use it as a boundary while
building the current query. i.e in this case, the query would be empty
after typing ".", clearing cached completions.

Release Notes:

- Fixed issue where completions menu flashed on every keystroke in TSX
files with emmet extension installed.
