Drag-and-drop from Nautilus on Wayland was broken by two issues:
- DropTarget only accepted COPY action, but Wayland compositor
pre-selects MOVE, causing GTK4 to silently reject all drops
- Two competing DropTarget controllers on the same widget caused
the gchararray target to match Nautilus formats first, swallowing
the drop before the FileList target could receive it
Merged both drop targets into a single controller that tries
FileList first, then File, then falls back to URI text parsing.
File manager integration was broken by wrong command syntax
(non-existent --files flag) and wrong binary path resolution
inside AppImage. Split into separate GTK/CLI binary resolution
with APPIMAGE env var detection.
- Redesign tutorial tour from modal dialogs to popovers pointing at actual UI elements
- Add beginner-friendly improvements: help buttons, tooltips, welcome wizard enhancements
- Add AppStream metainfo with screenshots, branding, categories, keywords, provides
- Update desktop file with GTK category and SingleMainWindow
- Add hicolor icon theme with all sizes (16-512px)
- Fix debounce SourceId panic in rename step
- Various step UI improvements and bug fixes
M8: Pre-compile regex once before rename preview loop instead of
recompiling per file. Adds apply_simple_compiled() to RenameConfig.
M9: Cache font data in watermark module using OnceLock (default font)
and Mutex<HashMap> (named fonts) to avoid repeated filesystem walks
during preview updates.
M12: Add 150ms debounce to watermark opacity, rotation, margin, and
scale sliders to avoid spawning preview threads on every pixel of
slider movement.
M13: Add 150ms debounce to compress per-format quality sliders (JPEG,
PNG, WebP, AVIF) for the same reason.
M14: Move thumbnail loading to background threads instead of blocking
the GTK main loop. Each thumbnail is decoded via image crate in a
spawned thread and delivered to the main thread via channel polling.
CLI: add UTC suffix to timestamps, validate image extensions on
single-file input, canonicalize watch paths for reliable matching,
derive counter_enabled from template presence, warn when undo count
exceeds available batches.
Core: apply space/special-char transforms in template rename path,
warn on metadata preservation for unsupported formats, derive AVIF
speed from compress preset quality level.
GTK: use buffer size for apples-to-apples compress preview comparison,
shorten approximate format labels, cache file sizes to avoid repeated
syscalls on checkbox toggle, add batch-update guard to prevent O(n^2)
in select/deselect all, use widget names for reliable progress/log
lookup, add unique suffix for duplicate download filenames.
- PNG chunk parsing overflow protection with checked arithmetic
- Font directory traversal bounded with global result limit
- find_unique_path TOCTOU race fixed with create_new + marker byte
- Watch mode "processed" dir exclusion narrowed to prevent false skips
- Metadata copy now checks format support before little_exif calls
- Clipboard temp files cleaned up on app exit
- Atomic writes for file manager integration scripts
- BMP format support added to encoder and convert step
- Regex DoS protection with DFA size limit
- Watermark NaN/negative scale guard
- Selective EXIF stripping for privacy/custom metadata modes
- CLI watch mode: file stability checks, per-file history saves
- High contrast toggle preserves and restores original theme
- Image list deduplication uses O(1) HashSet lookups
- Saturation/trim/padding overflow guards in adjustments
Critical fixes:
- Prevent path traversal via rename templates (sanitize_filename)
- Prevent input == output data loss (paths_are_same check)
- Undo now uses actual executor output paths instead of scanning directory
- Filter empty paths from output_files (prevents trashing CWD on undo)
- Sanitize URL download filenames to prevent path traversal writes
High severity fixes:
- Fix EXIF orientation 5/7 transforms per spec
- Atomic file creation in find_unique_path (TOCTOU race)
- Clean up 0-byte placeholder files on encoding failure
- Cap canvas padding to 10000px, total dimensions to 65535
- Clamp crop dimensions to minimum 1px
- Clamp DPI to 65535 before u16 cast in JPEG encoder
- Force pixel path for non-JPEG/TIFF metadata stripping
- Fast path now applies regex find/replace on rename stem
- Add output_dpi to needs_pixel_processing check
- Cap watermark image scale dimensions to 16384
- Cap template counter padding to 10
- Cap URL download size to 100MB
- Fix progress bar NaN when total is zero
- Fix calculate_eta underflow when current > total
- Fix loaded.len()-1 underflow in preview callbacks
- Replace ListItem downcast unwrap with if-let
- Fix resize preview division by zero on degenerate images
- Clamp rename cursor position to prevent overflow panic
- Watch mode: skip output dirs to prevent infinite loop
- Watch mode: drop tx sender so channel closes on exit
- Watch mode: add delay for partially-written files
- Watch mode: warn and skip unmatched files instead of wrong preset
- Clean temp download directory on app close
- Replace action downcast unwrap with checked if-let
- Add BatchResult.output_files for accurate undo tracking
Users can now drag image URLs from web browsers into the image
step. URLs ending in common image extensions are downloaded to a
temp directory and added to the batch. Uses GIO for the download
in a background thread.
Upgrade the Add Images step from a plain ListBox to a GtkGridView
with thumbnail rendering. Each item shows a scaled thumbnail with
a checkbox overlay for include/exclude, and filename label below.
Thumbnails load asynchronously using Pixbuf at reduced size.
Uses GObject subclass (ImageItem) for the list model.
Escape now goes to previous wizard step (cancel/go back). When
a folder with subfolders is dropped on the images step, an alert
dialog asks whether to include subfolder images. The choice is
remembered for the rest of the session.
- Register select-all-images and deselect-all-images actions
- Wire Ctrl+A to clear exclusion set, Ctrl+Shift+A to exclude all
- Both shortcuts update checkbox state and count label in images step
- Make set_all_checkboxes_in public for cross-module access
- Each image row now has a CheckButton for include/exclude from processing
- Select All clears exclusion set, Deselect All adds all files to it
- Count label shows "X/Y images selected" when some are excluded
- Processing respects excluded files - only processes checked images
- Clear All also resets exclusion set
- AppState gains excluded_files HashSet for tracking
Add crop to aspect ratio (8 ratios), trim whitespace, and canvas padding
controls to the adjustments step per design doc. Wire brightness,
contrast, saturation, sharpen, grayscale, and sepia to JobConfig. Add
Select All / Deselect All toolbar buttons to images step. Include new
adjustment operations in output step summary.
Convert step: replace ComboRow with visual format card grid showing
icon, name, and description for each format. Much more beginner-friendly.
Images step: add per-image remove button on each file row so users
can exclude individual images from the batch.
Shortcuts: use adw::Dialog with structured layout since GtkShortcutsWindow
is deprecated in GTK 4.18+. Add file management and undo shortcuts.
Settings: wire thread count selection to actually save/restore the
ThreadCount config value instead of always defaulting to Auto.
