An external write that keeps a file's byte length and mtime was missed twice: the Maven launch fingerprint reused the stale class snapshot, and watcher events for clean open documents were dropped by the (mtime, length) stamp check.
The launch fingerprint now records a blake3 content hash for project files (toolchain inputs such as the JDK's lib/modules keep the stamp only) and bumps its version. Watcher events for clean documents compare the disk bytes with what saving the buffer would write; blind focus scans keep the stamp dedup, and forced refreshes after IDE disk operations still reload clean buffers.

Document::diff only trimmed the common prefix and suffix, so two distant
edits on disk became one change spanning everything between them. The
caret and scroll position inside that span were mapped to its start,
which made the editor jump to the first edit after an agent, formatter
or git operation rewrote the file.
Diff the changed middle line by line (Myers via similar, 50 ms deadline
with a coarser fallback) and emit one change per edited region, trimmed
to its differing characters. The frontend DocSync path produces the same
per-region changes, so external reloads, local history restores and
formatting keep the caret and view in place.

Unity projects (a folder with Assets and ProjectSettings/ProjectVersion.txt)
are detected without a generated solution: Assets / Packages become source
roots, ProjectSettings resources, and Unity's cache and build folders are
excluded before they exist. A Unity pane in the Project view shows the
editor version and hides .meta files, generated C# project files and
caches (each can be shown again).
Operations on assets under Assets keep their .meta files consistent:
rename and move carry the metadata (same GUID), delete removes both, copy
generates new GUIDs and updates references inside the copied group, and
file-move undo and workspace edits include the metadata. Destination
metadata conflicts and links inside the project are rejected before
anything changes.

gopls sends a document version for every file of a rename, including files
the editor never opened. Applying a workspace edit rejected any versioned
file without an open document as changed, so a Go rename touching a closed
file always failed with "changed; request the refactoring again". For a file
that isn't open, the preconditions captured with the edit now decide; an
edit without them is still rejected.
An edit's preconditions hashed disk contents plus unsaved buffers. Saving a
buffer moved its text from one to the other and changed the hash, so a
quick fix, rename or refactoring listed just before a save (autosave of a
freshly typed scratch, for one) failed with "changed; request the
refactoring again", and only the next attempt worked.
Unsaved buffers now stand in for their files' bytes in the hash, so saving
doesn't change it; edits, external writes and file operations still do.
Root cause, two parts:
- An explicit save (Save All before a checkout, before running, before Commit) also wrote documents that were not modified, running save actions such as stripping trailing whitespace and adding a final newline on them — files the user never touched gained whitespace-only changes. Saves now skip clean documents, as autosave already did.
- After our own VCS operations rewrote files (checkout, rollback, stash, patch, ignore, commit/worktree hooks, Directory Compare), clean editor buffers were only refreshed by the file watcher, which can miss a rewrite that keeps the length and the timestamp's millisecond. Those operations now reload clean buffers synchronously before returning, keeping each document's chosen encoding; modified buffers keep the existing conflict handling.

Multi-file refactorings could drop LSP document versions, overwrite content changed after a preview, or leave earlier files saved after a later write failed. Workspace edits now keep server versions and preview fingerprints, are validated on a staging copy, snapshot disk and open buffers, and roll back on commit failure (retaining recovery files if rollback fails). The whole edit is one Undo/Redo step in editors and in the notification. Version reads and transaction work run off the async workers. Closes#461.

With Transparent native-to-ascii conversion on, pasting or typing existing \uXXXX escapes into a .properties file and saving wrote them back as \u005CuXXXX, so the file on disk changed meaning.
Root cause: the shared properties encoder escaped the backslash of any valid ASCII Unicode escape. It now writes ASCII escapes as they are and only converts non-ASCII characters; a literal backslash right before a non-ASCII character is still protected. The same encoder serves every write path, so normal/auto save, find and replace in open and closed files, workspace edits, Local History restore and partial Git stage/commit are all covered.
Verified on macOS following the reporter's steps (paste escapes, save, reload externally); Windows and Linux not run.
Fixes#519
Open files only reloaded from file watcher events, so a change the watcher skipped stayed stale in its tab: excluded and git-ignored folders, files outside the project, and missed events.
- Re-check open documents against disk when the window gains focus, off the UI thread and debounced. Clean documents reload, dirty ones keep the existing warning, and unchanged ones cost one metadata call.
- Refresh the project tree and Git status on the same focus event.
- Add "Synchronize external changes when switching to the IDE window" under System Settings, on by default.
Fixes#563
Properties documents passed through charset decoding alone, leaving Unicode escapes in the shared document text.
- Add a default-off "Transparent native-to-ascii conversion" setting under the properties encoding and a stable action. Changing it reloads clean properties buffers in place; dirty buffers keep their codec.
- Decode eligible escapes and surrogate pairs when constructing documents, and save non-ASCII as uppercase escapes in pure ASCII. Backslash pairs, malformed escapes, unpaired surrogates and line terminator escapes stay literal, so an edit cannot split a property across lines.
- Use the same codec for search, closed-file readers, Git diffs, staging and partial commits. Clean saves and undone edits preserve the original bytes.
Fixes#519
HTML files in Angular projects were highlighted as plain HTML. Languages can now declare framework UI modes with root markers (angular.json, node_modules/@angular/core); files under such a root get the framework's editor mode, re-detected when a marker appears or disappears, and the root-marker lookup is shared with language server roots. The Angular Template mode (vendored @codemirror/lang-angular, MIT) adds @if/@for/@switch/@defer/@let blocks, key and animation binding names, and colours {{ }} delimiters.
Lazily loaded editor modes are now loaded before a document's first editor opens, so a file never renders as plain text first (this also left Angular templates uncoloured).
