Upstream: https://github.com/ftilmann/latexdiff/tree/1.3.4 (commit a69a053feddbf6bbd2747e351e440be05d415ddc). Copyright Frederik Tilmann and contributors. Distributed under GPL version 3 or later; Algorithm::Diff carries its upstream Perl/Artistic/GPL terms. Complete corresponding script sources, the upstream build recipe, copyright notices, and license texts are included beside the standalone script. ## TinyTeX / TeX Live The macOS distribution includes TinyTeX-1 v2026.09 from https://github.com/rstudio/tinytex-releases/releases/tag/v2026.09 with the SyncTeX packages listed in `desktop/tex-runtime-manifest.json`. TinyTeX is maintained by Yihui Xie and contributors; its distribution contains TeX Live software and packages with individual licenses. The private runtime retains upstream `LICENSE.TL`, `LICENSE.CTAN`, package metadata, documentation, and included sources. TeX Live licensing and corresponding source archives: https://tug.org/texlive/copying.html and https://tug.org/texlive/acquire.html. SyncTeX is maintained by Jérôme Laurens and contributors under its upstream MIT-style license. Package contents are not modified; only the portable distribution is assembled and relocated. ## Portable Git The macOS distribution includes the unmodified macOS arm64 portable Git release v2.53.0-4 from https://github.com/desktop/dugite-native/releases/tag/v2.53.0-4, including its supporting runtime files. Git is copyright its contributors and distributed under GPL version 2; the license is included in `desktop/vendor/GIT-COPYING` and the bundled runtime. Git source: https://github.com/git/git/tree/v2.53.0. Portable build recipes, component versions, and sources: https://github.com/desktop/dugite-native/tree/v2.53.0-4. Git is invoked as a separate executable for local document history and explicit repository operations. ## electron-updater Signed desktop updates use electron-updater 6.8.9 from https://github.com/electron-userland/electron-builder, under the MIT license. Its upstream license is included in the installed dependency. macOS installation uses Electron’s Squirrel.Mac integration.
