The record

Purpose: Delta Patcher is a desktop application for creating and applying xdelta patches to files.
Supported format: It creates and applies xdelta patches; patches in other formats require a different program.
Patch creation: Create mode records differences between an original file and a modified file in a new xdelta patch.
Patch application: Apply mode uses the original file expected by a patch and its matching .xdelta file to produce a patched output.
Embedded engine: The application embeds xdelta3, so a separate xdelta3 command-line installation is not required.
Validation and backup: Checksum validation helps detect a mismatched source file, and users can choose to preserve a backup of the original.
Large files: Version 3.1.5 added support for files larger than 4 GB.
Creation options: Creation options include compression level, secondary compression, source window, checksum, and an optional description.
Platforms: Current downloads are available for Windows, macOS 11 or later, and 64-bit GTK3 Linux systems.
License: Delta Patcher is open source and distributed under the GPL-2.0 license.
Distribution: Downloads are ZIP archives without a separate installer, and release assets are hosted on GitHub.
Limits: A patch and its original file must match; the application handles xdelta patches rather than multiple patch formats.
Website privacy: The site says Google Analytics storage is optional, advertising storage stays disabled, and users can change their analytics choice.
Support: The project directs users to GitHub for issues, discussions, source code, and releases.
