CTAN update: stocksize
by CTAN Announcements 02 Jan '26

02 Jan '26

João M. Lourenço submitted an update to the stocksize package. Version: 2.0.1 2026-01-01 License: lppl1.3c Summary description: A flexible and easy interface to paper (stock) dimensions Announcement text: ---------------------------------------------------------------------- Version 2.0.1 fixes the date and version number in the documentation. Version 2.0.0 introduces a major rewrite of the `stocksize` package. The update fundamentally changes the implementation to provide a more robust and reliable mechanism for managing nested page size changes. The key changes are: - Stack-Aware Geometry: Instead of a custom implementation, the package now patches `geometry`’s internal `\newgeometry` and `\restoregeometry` commands, making them operate as a true LIFO stack. This ensures that nested layout changes can be reliably restored in the correct order. - Automatic Physical Size Sync: The physical PDF page dimensions (e.g., `\pdfpagewidth`) are now automatically synchronized with the logical layout (`\paperwidth`) whenever the geometry is altered with the `\newstocksize{}` command. - New `patch-geometry` Option: A package option `[patch-geometry]` has been added to automatically synchronize the physical PDF page dimensions (e.g., `\pdfpagewidth`) and logical layout (`\paperwidth`) whenever the geometry is altered with the `\newgeometry{}` command. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/stocksize The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/stocksize/ ------------------------------------------------------------------------ Thanks for the upload.
