Features
— Unicode filename support for Windows and Mac.
— Added support for Japanese and Chinese languages.
— Thanks to Koichiro Oka for the help with the Japanese translation and Ge Hongbing for helping with the Chinese Translation.
— Natural sort for file tree instead of ASCII sort (similar to how Lightroom/Explorer/Finder sort). Natural sort now also for image files in the table, when sorting is set to «filename».
— Sped up Exif-Data loading by factor 5 or more. Increased number of Exif-Tool threads.
— Changed cropping logic. LRT will now support Portrait orientations in Portrait resolutions. This means, cropping sizes will not anymore be restricted by the landscape output dimensions, instead for Portrait renderings, portrait dimensions will get applied, like 1080×1920 and 2160×3840.
— Scrubbing through sequences with left/right cursor will now hide the curves, while scrubbing with up/down will show them as usually.
— Curves drawing. Curves will now scale better, especially for very large or very small sequences.
— Made Playhead more visible with different backgrounds.
— Added a button «Show in Explorer/Finder» to the dialog with the list of rendered videos. Fix: Internal Export and Render wouldn’t add the rendered Video to the List of Videos
— Importer: Added a warning when the user selects a parent folder with a large amount of files below (>15,000) to potentially prevent a long time scanning. Mac: Importer will not try to load contents of /Volumes or /Macintosh HD anymore recursively when those main folders would be selected as source.
— When editing with the internal editor, Visual Preview will now keep showing the previous state instead of popping back to the camera preview while redeveloping.
— Batch progress bars will now appear in a scrollpane, if many, and not cover more then ¼th of the screen height now.
— Copy / Paste whole sequence. This feature allows you to copy/paste a full set of XMP data from one sequence to the other, for example to match the editing of left/right stereo or pano photos.
— Auto Downloader for updates. If available, an update will be downloaded after the version check and installed after closing LRTimelapse the next time. Version check will now run while LRT is up and not only on when launching LRT. Set a different default version check delay for the main channel (24 hrs) and the beta channel (2 hrs).
— Added Copy context menu and keystroke to Log dialog and image properties dialog.

Improvements
— When resizing the preview via the split pane, the selected folder in the tree will be kept in the viewport. Also the last selected folder will be relocated more reliably after restart.
— NEV files will be detected as Video files on import.
— Made the capitalization in the English menus more consistent.
— Mac: /cores and /opt folders won’t be shown anymore.
— Added description of the error to the error dialog when rendering fails.
— Massive speed up of «Select Every Nth» feature, move and Remove Images.
— On Mac, when the render dialog or new version dialog was launched while the monitor was sleeping, the dialogs would show no content.
— Reworked internal message dialogs. The shouldn’t overlap each other anymore now and will be precreated to avoid issues in monitor sleep mode.
— Internal export and render will now export basic metadata to the intermediary sequence and this will allow timestamp overlays and subtitles to be created.
— When auto upgrading on windows, run the installer in Silent mode (no dialogs).
— Better naming of the entries in the column header popup menu to clarify, that the operations are being applied on the column only.
— DNG files from Jpg/Tiff would not get the right Whitebalance treatment automatically — the detection is now more reliable whether DNG files consist of JPG/Tiff Data (relative Whitebalance) or Raw Data (absolute Whitebalance). This makes the «Set Whitebalance Treatment» tool obsolete, it has been removed.
— Mac: DMG mount name will include the version now. Otherwise, with older update DMGs still mounted, the wrong update could be launched. When running the updater, before mounting the downloaded DMG Archive, older, still mounted DMG Archives will be unmounted. This can be controlled with the option «unmountLrtDmgFiles» in the config file.
— Nicer dialog for Rename Files with an example and also better logging.
— Rename Files with Prefixes (F2) will now also rename files, whose date/time prefix doesn’t correspond to the exif date and correct those.
— Importer will not create any cache folders (.lrt) on import drives anymore.
— Better error handling if exiftool is not available or running.
— Fixing of deleted/missing LRT adjustment masks.
— Added hint dialog to explain the «locks» when first doing a batch rendering.
— Improved the Ask for Lightroom Version Dialog

Fixes:
— Holy Grail Wizard: Stretch slider could introduce flicker.
— On long sequences with very close keyframes and heavy changes between them sometimes no smooth transition curve could be calculated. The fallback to a linear transition will now be applied if the distance between the keyframes is less than 4% of the sequence size (before it was 15 images).
— Move Images across Volumes/Devices would not remove the original image from the source drive.
— Aborting the Lens tagger dialog would throw an exception.
— Angle overflow when animating Circular masks
— Added localization to Lum/Contrast/Hue filter labels in filter panel.
— After «Clear Metadata» without reinitialization, save could fail.
— Load Snapshot would move the playhead through the sequence
— Loading the preview in the render dialog in some cases would be triggered more than once.
— In some cases the intervals wouldn’t be correctly displayed
— After switching from filename sort to date/time sort or vice versa, the intervals wouldn’t be recalculated.
— In rare cases trying to load a sequence after some batch processes produced an error and an empty table.
— Very short sequences with less than 10 images sometimes didn’t load completely.
— Updated the link for the adobe forum post where I request JPG support for the Adobe DNG Converter. However my hopes are little since this request is now 9 years old… : -(
— Batch processes sometimes could be ended when switching folders.
— Unnecessary delay at the beginning of Exif-Data-Reload.
— Metadata fixing for mixed WB treatments.
— Metadata/Clear and Reinitialize would load ExifData twice.
— White Balance initialization issue.
— Closing LRTimelapse without loading any folder would reset the last selected folder in the settings and start with the folder tree in default position next time.
— Metadata issues with DNG files created from JPGs.
— Keystrokes for Shift-Save (force Save) not correctly assigned.
— Table and Editor would not update in Visual Previews mode when Metadata was changed externally (by Lightroom).
— Auto-Transition on single column will not run the fix XMP routine anymore.
— Metadata issue with some JPGs.
— Fixing Metadata for missing/additional masks didn’t work in some situations.
— Importer could stall when scanning source files
— On Mac silicon, the Intel version of ffmpeg would have been used, now LRT comes with a universal binary for both platforms.
— Avoid overlapping dialogs on first launch.
— XMP Migration error from LRTimelapse 3.
— Various UI and Localization fixes.
