by CTAN Announcements 15 Sep '26

15 Sep '26

John Bowman submitted an update to the asymptote package. Version: 3.15 License: lgpl3 Summary description: 2D and 3D TeX-Aware Vector Graphics Language Announcement text: ------------------------------------------------------------------------ Unnecessary recompilation of the Vulkan, OpenGL, and WebGL shaders is avoided. An orthographic projection bug in the WebGL renderer was fixed. The empty version string in non-git builds was fixed. The Windows installer now detects a running asy.exe. A meaningful error message is shown for 3D scenes when the Windows Vulkan software renderer is unavailable, instead of exiting. An exit-time issue in non-IBL OpenGL scenes was fixed. Relocatable builds now use an empty sysdir. The release tarball now ships stripped binaries. Build issues were addressed; the minimum autoconf requirement was lowered. ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/asymptote The package’s files themselves can be inspected at https://mirrors.ctan.org/graphics/asymptote/ ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: show-pdf-tags
by CTAN Announcements 14 Sep '26

14 Sep '26

The LaTeX Project Team submitted an update to the show-pdf-tags package. Version: 1.6 License: mit Summary description: Extract PDF tags from tagged PDF files Announcement text: ------------------------------------------------------------------------ The XML output from show-pdf-tags has been extended to show the AF relationship and media-type of associated files. This is a breaking change, generated XML will show this information. All associated files associated to Formula will have the same values added: so it should be easy to update any test suites testing for the original format. < AssociatedFile name="mathml-1.xml" xmlns="" > < AssociatedFile name="mathml-1.xml" relationship="Supplement" media-type="application/mathml+xml" xmlns="" > < AssociatedFile name="tag-AFfile2.tex" xmlns="" > < AssociatedFile name="tag-AFfile2.tex" relationship="Source" media-type="application/x-tex" xmlns="" > The Schema have been updated to allow for these attributes (and to check that MathML associated files have relationship Supplement). They also allow some modified strucure element names in the LaTeX namespace to match code in current and planned latex-dev releases. Some experimental support to generate PDF Association "Tag Tree Diagrams" using PlantUML is also provided as XSLT stylesheets transforming the XML output to PlantUML syntax. ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/show-pdf-tags The package’s files themselves can be inspected at https://mirrors.ctan.org/support/show-pdf-tags/ ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: tugboat-plain
by CTAN Announcements 14 Sep '26

14 Sep '26

Karl Berry submitted an update to the tugboat-plain package. Version: 1.33 2026-09-12 License: other-free Summary description: Plain TeX macros for TUGboat Announcement text: ------------------------------------------------------------------------ An update to the tugboat-plain package, for TUGboat articles using plain TeX, now v1.33 2026-09-12. Notable changes: - formatting of footnotes changed to match the TUGboat LaTeX style (ltugboat.sty), including switching the font to \eightpoint. - footnotes now support automatic numbering, if the first argument to \footnote is empty. - new macro \titleref to typeset a book (etc.) title. - \abovecaptionskipamount, \normallineskip, \Thanh updated to match ltugboat. - incorporate the tugboat.cmn file into tugboat.sty, so there is only one implementation file. (The original purpose of tugboat.cmn was to be shared between the plain and LaTeX tugboat styles, but that never worked out.) Please see https://tug.org/TUGboat for deadlines, author info, an archive of all issues, and everything else relating to TUGboat. Suggestions and bug reports are always welcome; our general email address is tugboat(a)tug.org. And please submit articles for the next issue! ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/tugboat-plain The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/plain/contrib/tugboat/ ------------------------------------------------------------------------ Thanks for the upload.
