Oliver Kopp submitted an update to the scientific-thesis-cover package. Version number: 4.1.0 2026-06-12 License type: lppl1.3c Summary description: Provides cover page and affirmation at the end of a thesis Announcement text: ---------------------------------------------------------------------- Long-awaited update ### Added - Update the declaration to cover the use of AI tools: the affirmation text now references a "Use of AI Tools" appendix and the *Principles for the Use of Artificial Intelligence by Students at the University of Stuttgart*. See [#30](https://github.com/latextemplates/scientific-thesis-cover/pull/30) and [#36](https://github.com/latextemplates/scientific-thesis-cover/pull/36). - Add `Institute for Natural Language Processing` (`ims`, German: "Institut für Maschinelle Sprachverarbeitung") as an institute option, including its own address. See [#22](https://github.com/latextemplates/scientific-thesis-cover/pull/22) and [#23](https://github.com/latextemplates/scientific-thesis-cover/pull/23). - Add `VISUS` (Visualization Research Center / Visualisierungsinstitut der Universität Stuttgart) as an institute option, including its own address. See [#27](https://github.com/latextemplates/scientific-thesis-cover/pull/27). - Add the ability to add a logo at the top of the coverpage. See [#28](https://github.com/latextemplates/scientific-thesis-cover/pull/28). - Add document confirmations for multiple authors. See [#24](https://github.com/latextemplates/scientific-thesis-cover/pull/24). - Add `prozessanalyse` as a thesis type. See [#21](https://github.com/latextemplates/scientific-thesis-cover/pull/21). ### Changed - Rename the `iste` institute from "Institute of Software Technology" / "Institut für Softwaretechnologie" to "Institute of Software Engineering" / "Institut für Software Engineering". See [#32](https://github.com/latextemplates/scientific-thesis-cover/pull/32). - Switched continuous integration from CircleCI to GitHub Actions, installing TeX Live via [`zauguin/install-texlive`](https://github.com/zauguin/install-texlive) with the dependency list in `tl_packages` (generated with [@islandoftex/texmf/depp](https://gitlab.com/islandoftex/texmf/depp)). See [#37](https://github.com/latextemplates/scientific-thesis-cover/pull/37). - Added a GitHub Actions workflow that builds the CTAN submission archive (`release.sh`, the Linux port of `release.bat`) on every push, verifying that pandoc and `ctanify` produce `scientific-thesis-cover.tar.gz`. See [#37](https://github.com/latextemplates/scientific-thesis-cover/pull/37). ### Fixed - Fix `\Versicherung` / `\Affirmation` in two-column documents by declaring the internal two-column flag with `\providecommand`. See [#24](https://github.com/latextemplates/scientific-thesis-cover/pull/24). - Fix `ß` being displayed as `SS` in `Universitätsstraße`. See [#29](https://github.com/latextemplates/scientific-thesis-cover/pull/29). - Fix English name of IPVS: "Institute **for** Parallel and Distributed Systems" instead of "Institute **of** Parallel and Distributed Systems". See [#34](https://github.com/latextemplates/scientific-thesis-cover/pull/34) and [#35](https://github.com/latextemplates/scientific-thesis-cover/pull/35). - Load `csquotes` so that `\enquote` in the affirmation text (AI tools declaration) is defined. See [#37](https://github.com/latextemplates/scientific-thesis-cover/pull/37). - Load `iftex`/`ifluatex` so that `\ifluatex` is defined again, fixing an `Extra \fi` error on current TeX Live. See [#37](https://github.com/latextemplates/scientific-thesis-cover/pull/37). ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/scientific-thesis-cover More information is at https://www.ctan.org/pkg/scientific-thesis-cover ------------------------------------------------------------------------ Thanks for the upload.

New on CTAN: turkce-sayi
by CTAN Announcements via ctan-ann 13 Jun '26

13 Jun '26

Sonat Süer submitted the turkce-sayi package. Version number: 1.0 2026-06-11 License type: lppl1.3c Summary description: Automatic Turkish suffix handling for reference numbers Announcement text: ---------------------------------------------------------------------- Automatic Turkish suffix harmony for numbers in LuaLaTeX When a number in a Turkish document is produced by a cross-reference (\ref, \pageref, \cite), the correct form of any attached suffix depends on how that number is pronounced — information that is unavailable at editing time. Hardcoding a suffix works for some numbers but silently produces wrong output for others. turkce-sayi resolves this at compile time via LuaTeX. It looks up the phonological properties of the number's Turkish name and applies four transformation rules: consonant hardening/softening (sertleşme/yumuşama), two-way and four-way vowel harmony (ünlü uyumu), and buffer-letter insertion or vowel drop (kaynaştırma/düşme). Invariant morphemes such as -ki, -ken, and -yor are detected and vowel harmony is reset at their position so that subsequent morphemes harmonise correctly. The package requires LuaLaTeX. Examples: \trkappend{3}{'de} % → 3'te (sertleşme: üç ends in ç) \trkappend{6}{'de} % → 6'da (vowel harmony: altı has back vowel) \trkappend{2}{'inci} % → 2'nci (vowel drop: iki ends in vowel) \trkpageref{sec:intro}{'de} % → 5'te (suffix determined at compile time) \trkref{sec:results}{'inci} % → 3'üncü (section number resolved automatically) \trkbibref{smith2021}{'de} % → [3]'te (citation number resolved from .aux) ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/luatex/latex/turkce-sayi More information is at https://www.ctan.org/pkg/turkce-sayi ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: markdown
by CTAN Announcements 12 Jun '26

12 Jun '26

Vít Starý Novotný submitted an update to the markdown package. Version: 3.15.1-0-g51841b67 2026-06-11 License: lppl1.3c Summary description: Converting and rendering markdown documents inside TeX Announcement text: ------------------------------------------------------------------------ ### Fixes This version of the Markdown package has fixed the following issues: - Define unexpandable functions as protected. ([witiko/expltools#201][expltools-201], #644) [expltools-201]: https://github.com/witiko/expltools/pull/201 ### Defaults This version of the Markdown package has made the following changes to the default renderer and renderer prototype definitions. - Render bracketed spans by default. (8c3b0716) Previously, bracketed span contents were consumed by the default renderer prototype. - In LaTeX, format `[...]{.acronym}`s throughout the document. (#645) After this change, explicitly listed acronyms using the HTML class `acronym` will be recorded in the auxiliary file, so that they are applied throughout the document in the next compilation run. For example, assume the following LaTeX example document: ``` tex \documentclass{article} \usepackage[bracketed_spans]{markdown} \markdownSetup { acronyms = {HTML, YAML}, } \begin{document} \begin{markdown} HTML, JSON, and YAML are two staples of modern tooling that often get mentioned in the same breath, even though they live in very different layers of the stack. Here, the author has explicitly marked up [JSON]{.acronym}. \end{markdown} \begin{markdown} In the following compilation runs, the previous occurrence of JSON will also be correctly formatted as an acronym. \end{markdown} \end{document} ``` During the first compilation run, only HTML and YAML are formatted as acronyms in the first paragraph, not JSON, which is only formatted as an acronym in the second and third paragraphs. However, in the following compilation runs, JSON is formatted as an acronym throughout. ### Continuous integration This version of the Markdown package has made the following changes to our continuous integration: - Bump `softprops/action-gh-release` from 2 to 3. (added by @dependabot in #643) ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/markdown The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/generic/markdown/ ------------------------------------------------------------------------ Thanks for the upload.
