Introduce UIScrollController to provide frame-rate-independent wheel
interpolation, touch dragging, and momentum for code editors, terminals,
scroll views, and scrollable widgets while preserving the legacy instant
scrolling path.
Add a UISceneNode-level smooth-scrolling policy. Embedded scenes inherit
the root scene setting, new widgets snapshot it during construction, and
setSmoothScrollEnabled() can optionally apply changes to existing widgets
across the complete embedded-scene hierarchy.
Move native macOS scrolling and title-bar helpers into PlatformHelper,
enable native momentum from UIApplication, and explicitly enable it in
ecode. Preserve precise SDL2 and SDL3 wheel deltas for fractional momentum
events without changing normal integer wheel steps.
Replace the separate editor and terminal preferences in ecode and eterm
with one global smooth-scrolling setting, including legacy configuration
migration, live updates, and localized settings text.
Improve UITouchDraggableWidget momentum handling and add regression tests
for scrolling interpolation, pixel-aligned editor positions, scene
inheritance, widget overrides, and immediate policy application.
Decouple GL object sharing between native windows from auxiliary worker-thread context support. Platforms without threaded GL contexts, such as Haiku, must still share textures and other GL resources between their window contexts.
Always configure SDL_GL_SHARE_WITH_CURRENT_CONTEXT according to the requested context settings, while continuing to create the auxiliary thread context only on supported platforms. Explicitly reset the SDL attribute for non-shared contexts to avoid leaking state into subsequent window creation.
Apply the fix to both SDL2 and SDL3 backends. Also link the Haiku unit test executable against libbsd and libnetwork to resolve its PTY and socket dependencies.
Finalize zlib streams on every success and failure path after initialization,
preventing terminal frame compression from leaking encoder allocations.
Skip SDL window maximization in headless and terminal runtimes, where it is
meaningless and can leave worker-thread SDL error/TLS allocations alive.
Also correct the dormant Brotli streaming encoder loop so it validates
parameters, handles empty input and read failures, drains pending output,
finishes the stream completely, and destroys its state on every exit path.
Use Cocoa, Windows, and Haiku native drivers for terminal-mode OpenGL context
hosts instead of the unsupported offscreen driver. Keep hosts hidden and work
around Haiku SDL2 showing hidden windows during creation.
- Windows executable paths now always use GetModuleFileNameW(), with dynamic long-path support.
- Sys::getProcessPath() derives directly from the UTF-8 executable path.
- Windows working-directory APIs now use wide-character functions under both MinGW and MSVC.

- Introduce UIMultiDiffView as a first-class container for multi-file diffs, with a compact toolbar for expanding or collapsing all files, switching between unified and split views, and displaying aggregate file and line-change statistics.
- Calculate addition and removal totals during diff preparation so asynchronously prepared diffs do not need to rescan their contents on the UI thread. Cache the child diff views and expose the multi-diff state through the new component.
- Use UIMultiDiffView for regular diff tabs and Git commit details, removing the duplicated commit-specific toolbar, styling logic, tokenizer state, and view-mode handling. Preserve the original Git commit toolbar appearance, spacing, icons, tooltips, and colored changed-files summary.
- Keep the existing UIDiffView multi-file factory available for compatibility and add regression coverage for aggregate statistics, toolbar visibility, unified/split propagation, collapse state, prepared diffs, and large patches.

- add a native file-dialog and message-box multi-window example
- add integration coverage for context switching, input, resources, modality, and closing
Extract frame damage detection into a private reusable implementation and add
release benchmarks for representative GUI damage patterns at 720p, 1080p,
and 4K.
Use tile-major traversal for smaller framebuffers and cache-friendly row-major
traversal above 16 MiB, with reusable scratch storage and no whole-frame
equality precheck. Determine full-frame updates from the completed damage
bounds instead of prematurely falling back based on dirty-tile area.
Present benchmark results as a table showing each strategy, the selected
production path, its gap to the fastest candidate, and resulting transfer
size.
Enable persistent root-image and damage updates automatically only when
TERM=eterm, since Kitty a=f root-image edits are not consistently supported
by other terminal emulators.
Use reliable anonymous full-frame transfers elsewhere while preserving the
environment variables as explicit overrides. Document the compatibility
rationale and the dependency of damage updates on persistent images.

Expose MIME-based clipboard data operations through the Clipboard interface, with unsupported defaults for SDL2.
Implement lazy data providers, cleanup callbacks, MIME type enumeration, data retrieval, availability checks, and clipboard clearing for SDL3.
Exclude symbolic remote refs such as origin/HEAD from the branch list.
Remove the corresponding local remote-tracking ref after deleting a
remote branch, and prune stale refs when pulling.
Add persistent Kitty image presentation with RGB24 framebuffer updates,
tile-based damage detection, adaptive zlib compression, chunked Base64
transmission, and unchanged-frame suppression. Fall back to complete updates
when damage exceeds the configured threshold.
Expose environment controls for damage updates, persistent presentation, and
zlib compression level. Resolve presentation policy once during initialization
to keep environment parsing outside the frame path.
Repeat a=f on animation-frame continuation chunks as required by the Kitty
protocol, and suppress graphics acknowledgements from the terminal input
stream.
Complete Kitty keyboard translation for punctuation, function, keypad,
modifier, lock, and navigation keys. Preserve associated multi-codepoint text
and disambiguate Backspace from Delete using their protocol context.
Fix IOStreamMemory::write() to report bytes written so multi-chunk compression
works correctly, avoid stdout logging in the offscreen examples, and add
regression coverage for compressed streams and chunked frame updates.
Add process-level native, headless, and terminal runtime modes while keeping
the SDL2/SDL3 window backends responsible for creating the graphics context.
Use SDL's offscreen video driver with an eepp-owned logical root FBO for
headless rendering. Add caller-owned RGB24/RGBA32 framebuffer readback through
the renderer abstraction without leaking GL calls into the Window namespace.
Introduce a generic FramePresenter boundary and a Kitty presenter that streams
chunked direct RGB24 frames from a bounded worker queue. Optimize Base64
encoding for this streaming path.
Add POSIX and Windows terminal lifecycle support, Kitty keyboard input,
SGR-Pixels mouse input, focus handling, and terminal pixel-size resize events.
Inject translated events through a thread-safe Input queue so applications
continue using the normal input path.
Make UIApplication independent of physical displays in offscreen modes,
preserve native runtime behavior, and report the selected runtime and
presentation mode during initialization.
Add Sys::setEnv() for portable process environment configuration.
Add Kitty keyboard protocol negotiation, state stacks, and semantic
key encoding with support for alternate keys, event types, associated
text, and reporting all keys as escape sequences.
Forward key press, repeat, and release events through the terminal
worker while preserving legacy input behavior. Keep AltGr composition
distinct from Alt shortcuts and correlate SDL text events to prevent
missing or duplicated international-layout input.
Add protocol documentation and unit coverage for negotiation, state
transitions, modifiers, function and keypad keys, shifted input,
AltGr composition, repeats, releases, and duplicate suppression.

Avoid enumerating every installed font during SystemFontResolver warmup.
Use native platform matching for generic families and lazily resolve
fallback fonts when a missing glyph is encountered.
Cache generic and codepoint fallback results, preserve collection face
indices, and validate native matches with FreeType. Improve CoreText,
DirectWrite, and Fontconfig matching while retaining full enumeration
for font-listing APIs.
Add a Fontconfig override for testing the backend on macOS and extend
resolver coverage for lazy matching, CJK fallback, and enumeration.
Make pixel-exact subpixel rendering tests disable HiDPI so their
framebuffer dimensions remain deterministic on Retina displays.
Avoid executing native menu key equivalents twice when SDL also forwards
the same key-down event through eepp's keybinding dispatcher.
Preserve native menu item activation for mouse clicks.
Hide the "Hold Shift to keep menu open" hint while the native macOS menu
bar is enabled.
