Marshall Bowers	257e0991d8	collab: Increase minimum required version to connect (#36255 ) This PR increases the minimum required version to connect to Collab. Previously this was set at v0.157.0. The new minimum required version is v0.198.4, which is the first version where we no longer connect to Collab automatically. Clients on the v0.199.x minor version will also need to be v0.199.2 or greater in order to connect, due to us hotfixing the connection changes to the Preview branch. We're doing this to force clients to upgrade in order to connect to Collab, as we're going to be removing some of the old RPC usages related to authentication that are no longer used. Therefore, we want users to be on a version of Zed that does not rely on those messages. Users will see a message similar to this one, prompting them to upgrade: <img width="1209" height="875" alt="Screenshot 2025-08-15 at 11 37 55 AM" src="https://github.com/user-attachments/assets/59ffff3e-8f82-4152-84a8-776c691eaaee" /> > Note: In this case I'm simulating the error state, which is why I'm signed in via Cloud while still not being able to connect to Collab.

Oleksiy Syvokon	7671f34f88	agent: Create checkpoint before/after every edit operation (#36253 ) 1. Previously, checkpoints only appeared when an agent's edit happened immediately after a user message. This is rare (agent usually collects some context first), so they were almost never shown. This is now fixed. 2. After this change, a checkpoint is created after every edit operation. So when the agent edits files five times in a single dialog turn, we will now display five checkpoints. As a bonus, it's now possible to undo only a part of a long agent response.

Daniel Sauble	708c434bd4	workspace: Highlight where dragged tab will be dropped (#34740 ) Closes #18565 I could use some advice on the color palette / theming. A couple options: 1. The `drop_target_background` color could be used for the border if we didn't use it for the background of the tab. In VSCode, the background color of tabs doesn't change as you're dragging, there's just a border between tabs. My only concern with this option is that the current `drop_target_background` color is a bit subtle when used for a small area like a border. 2. Another option could be to add a `drop_target_border` theme color, but I don't know how much complexity this adds to implementation (presumably all existing themes would need to be updated?).

smit	f8b0105258	project: Fix LSP TextDocumentSyncCapability dynamic registration (#36234 ) Closes #36213 Use `textDocument/didChange` ([docs](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_synchronization)) instead of `textDocument/synchronization`.

David Kleingeld	4f0b00b0d9	Add component NotificationFrame & CaptureAudio parts for testing (#36081 ) Adds component NotificationFrame. It implements a subset of MessageNotification as a Component and refactors MessageNotification to use NotificationFrame. Having some notification UI Component is nice as it allows us to easily build new types of notifications. Uses the new NotificationFrame component for CaptureAudioNotification. Adds a CaptureAudio action in the dev namespace (not meant for end-users). It records 10 seconds of audio and saves that to a wav file.

Lukas Wirth	8d6982e78f	search: Fix some inconsistencies between project and buffer search bars (#36103 ) - project search query string now turns red when no results are found matching buffer search behavior - General code deduplication as well as more consistent layout between the two bars, as some minor details have drifted apart - Tab cycling in buffer search now ends up in editor focus when cycling backwards, matching forward cycling - Report parse errors in filter include and exclude editors Release Notes: - N/A	2025-08-15 09:56:47 +02:00
smit	23d0433158	linux: Fix keyboard events not working on first start in X11 (#36224 ) Closes #29083 On X11, `ibus-x11` crashes on some distros after Zed interacts with it. This is not unique to Zed, `xim-rs` shows the same behavior, and there are similar upstream `ibus` reports with apps like Blender: - https://github.com/ibus/ibus/issues/2697 I opened an upstream issue to track this: - https://github.com/ibus/ibus/issues/2789 When this crash happens, we don’t get a disconnect event, so Zed keeps sending events to the IM server and waits for a response. It works on subsequent starts because IM server doesn't exist now and we default to non-XIM path. This PR detects the crash via X11 events and falls back to the non-XIM path so typing keeps working. We still need to investigate whether the root cause is in `xim-rs` or `ibus-x11`. Release Notes: - Fixed an issue on X11 where keyboard input sometimes didn’t work on first start.	2025-08-15 12:51:32 +05:30
Alvaro Parker	4d27b228f7	remote server: Use env flag to opt out of musl remote server build (#36069 ) Closes #ISSUE This will allow devs to opt out of the musl build when developing zed by running `ZED_BUILD_REMOTE_SERVER=nomusl cargo r` which also fixes remote builds on NixOS. Release Notes: - Add a env flag (`ZED_BUILD_REMOTE_SERVER=nomusl`) to opt out of musl builds when building the remote server	2025-08-14 20:31:01 -06:00
