Full notes

This week's release includes BYOK support for GPT-6.1 Sol, on-the-fly model selection for new subagents, automatic subagent compaction, a unified/split toggle for diffs opened from the command line, and dynamically fetched OpenCode models.

## Features

### AI

- Added an optional `model` parameter to `spawn_agent` to choose a model for that spawn instead of using the configured subagent model or inheriting the parent model, with the active model shown in its card. ([#64498](https://github.com/zed-industries/zed/pull/64498); thanks [itsfuad](https://github.com/itsfuad))
- Added BYOK support for GPT-6.1 Sol with an OpenAI API key. ([#64968](https://github.com/zed-industries/zed/pull/64968); thanks [ktKongTong](https://github.com/ktKongTong))
- Added Grok 4.7 to the SuperGrok and xAI providers and made it their recommended default. ([#64567](https://github.com/zed-industries/zed/pull/64567); thanks [raphaelluethy](https://github.com/raphaelluethy))
- Added the `agent.threads_sidebar.auto_open` setting to control whether opening a folder in an existing window also opens the Threads Sidebar. ([#64259](https://github.com/zed-industries/zed/pull/64259), [#64395](https://github.com/zed-industries/zed/pull/64395); thanks [jackhwalters](https://github.com/jackhwalters) and [joshkent94](https://github.com/joshkent94))
- Added support for `"..."` in `edit_predictions.disabled_globs` and `edit_predictions_disabled_in` so settings can extend inherited edit prediction exclusions and scopes. ([#64540](https://github.com/zed-industries/zed/pull/64540), [#64546](https://github.com/zed-industries/zed/pull/64546); thanks [porada](https://github.com/porada))
- Enabled compaction for subagents. ([#64135](https://github.com/zed-industries/zed/pull/64135))
- Improved OpenCode model availability by fetching the Zen and Go model list dynamically instead of relying on one bundled with Zed. ([#64585](https://github.com/zed-industries/zed/pull/64585))
- Improved performance when resolving OpenCode models. ([#64666](https://github.com/zed-industries/zed/pull/64666))
- Improved Threads Sidebar sizing so changes to `agent.threads_sidebar.default_width` take effect even after manually resizing the sidebar. ([#64395](https://github.com/zed-industries/zed/pull/64395); thanks [joshkent94](https://github.com/joshkent94))
- Hid deprecated OpenCode models. ([#64666](https://github.com/zed-industries/zed/pull/64666))

### Git

### Terminal

- Added support for `"..."` in `terminal.path_hyperlink_regexes` to extend inherited regexes without repeating them. ([#64552](https://github.com/zed-industries/zed/pull/64552); thanks [porada](https://github.com/porada))

- Added macOS three-finger Look Up and translation gestures for text in focused Markdown previews. ([#59297](https://github.com/zed-industries/zed/pull/59297); thanks [cppcoffee](https://github.com/cppcoffee))

### Windows

### Other

## Breaking Changes and Notices

- Removed Stop controls from external-agent-managed terminals, which are controlled by the agent rather than a local process. ([#64544](https://github.com/zed-industries/zed/pull/64544))
- Changed Threads Sidebar settings to `agent.threads_sidebar.position`, `agent.threads_sidebar.default_width`, and `agent.threads_sidebar.auto_open`, grouped together in the Settings Editor. Existing settings are migrated automatically. ([#64395](https://github.com/zed-industries/zed/pull/64395); thanks [joshkent94](https://github.com/joshkent94))
- Changed the shortcut for closing the active dock from `cmd-w` (macOS) or `ctrl-w` (Linux/Windows) to `ctrl-alt-w` on all platforms. ([#64515](https://github.com/zed-industries/zed/pull/64515))
- Changed `terminal.path_hyperlink_regexes` so a top-level `"..."` entry now inserts inherited regexes. To retain the previous three-character regex, replace that entry with `["..."]`. ([#64552](https://github.com/zed-industries/zed/pull/64552); thanks [porada](https://github.com/porada))
- Stopped importing VS Code’s `files.watcherInclude` as `file_scan_inclusions`; watch roots are not Git-ignore overrides. ([#64440](https://github.com/zed-industries/zed/pull/64440); thanks [porada](https://github.com/porada))
