Files can now be opened without a project. A file dropped on the Welcome screen, picked with File › Open File…, or passed on the command line or to a second instance opens in a lightweight window: editor tabs only, with no project tree, indexing, language servers, VCS or project tool windows. Syntax highlighting, find, save, undo and Local History still work. More files opened later join the same window as new tabs. Open as Project in the status bar opens the file's directory as a full project, following the open-project policy, and reopens the file there.
Backend: a light session reuses Project with an unindexed index, no LSP or VCS, and a flat watch on each opened file's directory. It is never reused as a project for the same root. Previously a file passed at launch opened its parent directory as a project.
* feat(agents): Show subagents as their own conversations
Agents that support ACP subagent sessions (Claude Code, Codex) now run each
subagent as a child session. Its tool calls and messages no longer mix into
the task's conversation: the parent shows a card per subagent with its state,
tool call count, latest step, task and result, and the card opens the
subagent's own conversation.
- Route session/update by session id; subagent settings and usage stay out
of the task.
- Subagent permission requests are answered in the task's conversation,
named after the subagent.
- Subagent conversations are saved with the task; a running subagent is
marked stopped after a restart.
- A running subagent can be stopped on its own.
* fix(agents): Save a subagent's state when it changes after the turn
Fixes#117
Inside an AppImage, AppRun and the linuxdeploy GTK/GStreamer hooks point LD_LIBRARY_PATH, PATH, XDG_DATA_DIRS, GIO_MODULE_DIR, GTK_PATH, GST_PLUGIN_* … into the mounted image, and every child inherited them, so host programs loaded the image's older libraries (curl + bundled nghttp2 → symbol lookup error when installing Kotlin LSP). ide_core::process::prepare (formerly no_window) now gives children the host environment back: entries inside $APPDIR are dropped (a <NAME>_ORIG wins), emptied variables and the runtime's launch variables are removed, explicit call-site values are kept; the IDE process itself is unchanged. Covers all spawn sites that used no_window plus terminal/run PTYs, run configuration environments and stop commands, login-shell probes, attach ps/kill, docker PATH, tool search PATH and the Linux browser opener. No-op outside an AppImage. Not verified on a Linux AppImage.

* feat(editor): Drag tabs and files between split panes
HTML5 drag and drop never reaches the webview while native file drop is
enabled, so tab, project-file and changelist drags did nothing. They now
run on pointer events:
- Drag an editor tab onto another pane, or onto a pane's edge to split it.
- Drag files from the Project view into an editor pane (center opens them
there, an edge opens them in a new split).
- Drag files between changelists in the Commit view.
- "Drag-and-drop with Alt pressed only" applies to tabs and stripe buttons.
* fix(lsp): Deliver server settings and start servers on a supported JDK
- workspace/configuration answers a server's own section (basedpyright)
from its settings block; basedpyright runs in "standard" mode and keeps
auto search paths on, so `src/` layouts resolve from `tests/`.
- jdtls: formatting follows the editor indent, calls complete without
guessed arguments, and JDK internals stay out of completion.
- `max-java` in a language server config picks an installed JDK no newer
than that (kotlin-language-server fails on JDK 25).
- Server initialization may take up to 5 minutes (first Gradle import).
- `lsp_resend_diagnostics` re-emits stored diagnostics after a reload.
- Spelling only checks declared names (not called methods like
`substring`) and accepts plurals of known software terms.
* feat(editor): Quick fixes, completion and navigation while typing
Quick fixes
- Errors get a red quick-fix bulb; Apply Quick Fix (⌥⇧↵) fixes the most
severe problem at the caret, and the error hover offers the fix directly.
- Code generated by a code action is re-indented to the file's style.
- Python: Implement abstract methods (⌃I or the bulb) from the bases.
- Duplicate code actions are listed once.
Completion
- Overloads sharing a name, and a name importable from several modules,
are no longer merged into one entry.
- Auto-import entries show the module they import from.
- Call snippets without a stop (`new ArrayList<>()`) leave the caret inside
the parentheses with parameter info, or past them when nothing takes
arguments; parameter info also opens after server call snippets.
- The selected item is resolved ahead of acceptance, so its auto-import
is applied (rust-analyzer).
Navigation and diagnostics
- Language server requests wait for pending edits, so Go to Declaration
right after typing answers for the current text; an empty answer right
after an edit is retried while the server catches up.
- Diagnostics come back after a window reload; error underlines stay
visible under typo / unused highlighting.
- Implementation gutter markers no longer refresh in a loop while the
server reports progress.
- A missing alternative server no longer shows as a server error.
* chore(lint): Skip agent worktrees under .claude
* fix(editor): Skip cancelled LSP requests and limit generated-code reformat
- Requests cancelled while waiting for pending edits are not sent.
- Code generated by an action is reformatted per changed hunk, so an added
import doesn't reformat the code between it and the generated lines.
- A long busy spell caused by a settle refresh re-runs it only once.
- Files dropped on a file row of another changelist move to that changelist.
- Python Implement methods: a nested class without bases ends the lookup,
class bodies continue through unindented string lines, and
`@abstractproperty` stubs become `@property`.
- Resend diagnostics goes through the host ops, and custom servers get
`max_java`.
* fix(editor): Rank the exact type first in Java constructor completion
jdtls appends the call or body to filterText (`String(${0})`); matching
on the label instead lets typing `String` rank `String` above
`StringBuilder` and the other types sharing its sort text.
* fix(editor): List identical completion items once
kotlin-language-server repeats a class once per classpath entry declaring
it, so `String()` and `String` were listed three times each.
* fix(editor): Keep the internal cancellation message out of the UI text catalog
Language servers can be configured from settings.toml (global or project) and Settings › Language Servers: arguments, environment, initialization options and workspace settings per server, enable/disable, and any stdio LSP server can be added for a language. Settings-only changes are pushed with workspace/didChangeConfiguration; launch changes restart the server.
Also: re-enabling a server now detaches and stops the fallback that stood in for it, and a server added from the dialog is written as its own [languageServers.<name>] table.
