CTAN update: spotxcolor
by CTAN Announcements 19 Mar '26

19 Mar '26

Munehiro Yamamoto submitted an update to the spotxcolor package. Version: 1.4 2026-03-17 License: lppl1.3c Summary description: Modern spot color support for the xcolor package Announcement text: ---------------------------------------------------------------------- Changes since v1.0: - Fixed spot color output for \color, \textcolor, and \pagecolor. In v1.0, these commands fell back to CMYK values instead of producing true PDF Separation color space operators. As of v1.4, all standard xcolor commands — including tinted expressions like DIC161s!50 — correctly generate spot color output on all engines (pdfTeX, LuaTeX, XeTeX, and dvipdfmx). - Fixed spot color output for PGF/TikZ drawing commands. TikZ \fill, \draw, and low-level PGF color commands now produce spot color operators for both fill and stroke independently. - Fixed spot color output for PGF uncolored pattern fills. Hatching and dot patterns (both legacy `patterns` and modern `patterns.meta` libraries) now use a [/Pattern [/Separation ...]] color space, producing true spot color output in pattern fills. - Added user manual (spotxcolor.tex) with a feature/limitation summary table. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/spotxcolor The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/spotxcolor/ ------------------------------------------------------------------------ Thanks for the upload.

Sébastien Gross submitted the svg-animate package. Version number: 1.0 2026-03-16 License type: agpl3 Summary description: Generate animated SVG diagrams with TikZ Announcement text: ---------------------------------------------------------------------- svg-animate is a new LaTeX package for producing step-by-step animated SVG diagrams with TikZ. Animations are implemented as SMIL keyframes embedded in the SVG output, so they run natively in any web browser with no JavaScript and no external dependencies. The animation model is simple: a TikZ picture is divided into discrete steps, and each element is revealed or hidden at specific steps via instantaneous opacity transitions. The same source file produces both an animated SVG (via latex + dvisvgm) and a clean static PDF (via xelatex or lualatex), making it suitable for web publishing and print from a single source. Key features: - \begin{animate} / \reveal / \animstep — minimal, intuitive interface - Per-step durations, looping or one-shot playback - Multi-step and range visibility (step={1,3-5}) - Blinking elements with configurable amplitude (blink=) - Static fallback for PDF output (\noanimate, static key) - Cascading options from global to per-element level Requirements: PGF/TikZ >= 3.1.9, dvisvgm >= 2.9, TeX Live 2022+ or MiKTeX 22+. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/svg-animate More information is at https://www.ctan.org/pkg/svg-animate ------------------------------------------------------------------------ Thanks for the upload.

Vít Starý Novotný submitted an update to the expltools package. Version: 2026-03-13 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: ---------------------------------------------------------------------- ## expltools 2026-03-13 ### explcheck v0.18.2 #### Fixes This version of explcheck has fixed the following problems: - Support `c`-type arguments in variable and constants declarations, definitions, and uses. (#187) This improved [code coverage][] from ca 21% to 25% of all expl3 tokens on TeX Live 2024. - Do a better job detecting arguments in unrecognized replacement texts when extracting control sequence name patterns from `c`-type arguments in function calls. (#187) - In semantic analysis, consider the base variables in indirect variable definitions to be used, similarly to how base functions in indirect function definitions are considered used. (#187) This has removed a dozen false positive detections of issue W415 (Unused variable or constant) on TeX Live 2024. - Include `\q_no_value` among well-known expl3 control sequence names. (#187) - Have the issue E417 (Setting a variable as a constant) mask the issue E421 (Globally setting a local variable). (#187) This has removed a couple questionable detections of the issue E421 on TeX Live 2024. - Only consider potentially used function (variant) (un)definitions in the flow analysis. (suggested by @lostenderman in #156, fixed in #187) This change improves processing time by about 3% for an average package file in TeX Live 2024, and by up to 91% (or 11×) for large files such as `expl3-code.tex` when flow analysis is enabled despite incomplete code understanding. It also reduces the memory footprint of flow analysis by up to 4× for those files. After this change, the default value of the Lua option `max_reaching_definition_inner_loops` has been reduced from 650,000 to just 350,000 inner-loop iterations. Overall, the changes in the past two releases have reduced the processing time for large files such as `expl3-code.tex` from months to a little over an hour (up to 800×) when flow analysis is enabled despite incomplete code understanding, and have reduced the memory footprint of flow analysis by up to 12× for those files.

This release brings major enhancements for complex graphics, ensuring that your spot colors remain print-safe across all major TeX engines. ## Major Changes in v1.0 (since v0.14): * Advanced TikZ/PGF Support: Integrated comprehensive patches to resolve ColorSpace dictionary collisions with PGF. Spot colors now work seamlessly with complex TikZ graphics, basic shapes, and function graphs without destroying PDF resources. * CMYK Pattern Fills: Injected a core patch into PGF to force uncolored patterns (both legacy patterns and modern patterns.meta) to use CMYK instead of hardcoded RGB. This guarantees that spot colors used in TikZ patterns safely fall back to CMYK, preventing print separation issues. * Explicit Driver Support: Improved compatibility and explicit fallback mechanisms for dvipdfmx, pdftex, and luatex. * License: Updated the package license to LPPL v1.3c or later. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/spotxcolor The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/spotxcolor/ ------------------------------------------------------------------------ Thanks for the upload.

Version: 2.0 2026-03-01 License: mit Summary description: Adobe Photoshop Data format (PSD) support for graphicx package Announcement text: ---------------------------------------------------------------------- ## Major Updates in `graphicxpsd` v2.0 * **Transition to `expl3**`: Completely rewrote the package core using the modern LaTeX3 (`expl3`) interface, improving maintainability and namespace cleanliness. * **Modern Option Processing**: Replaced legacy option handling with the `l3keys` module for robust and flexible key-value processing. * **Native Shell Escape**: Removed the dependency on the external `shellesc` package. Now utilizes the native `expl3` function (`\sys_shell_now:e`) to execute external commands safely. * **Smart Engine Detection**: Implemented the `l3sys` module to automatically detect the TeX engine and output format (PDF vs. DVI), providing a smarter fallback mechanism without legacy conditional branches. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/graphicxpsd The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/graphicxpsd/ ---------------------------------------------------------------------- Thanks for the upload.

Version number: 1.1.0 2026-03-11 License type: lppl1.3c Summary description: Lightweight environment for typesetting Python code Announcement text: ---------------------------------------------------------------------- We are pleased to announce pyjupyter v1.1.0, the second release of the LaTeX package for displaying Python code in Jupyter-style boxes. This release introduces significant enhancements and customization options based on user feedback. Users can now select from multiple monospaced fonts, including sourcecodepro, beramono, inconsolata, lmtt, courier, and txtt, allowing greater typographic flexibility. The package also supports adjustment of the code font size using standard LaTeX sizes such as tiny, scriptsize, footnotesize, small, normalsize, and large. Syntax highlighting has been improved to handle Python operators, keywords, and comments more accurately for better readability. Additionally, all tcolorbox options are now fully supported, including background and frame colors, corner rounding, spacing, and other layout customizations.

New on CTAN: spotxcolor
by CTAN Announcements via ctan-ann 12 Mar '26

12 Mar '26

Munehiro Yamamoto submitted the spotxcolor package. Version number: 0.14 2026-03-12 License type: mit Summary description: Modern Spot Color support for the xcolor package Announcement text: ---------------------------------------------------------------------- This package provides robust and modern spot color (e.g., DIC, PANTONE) support for the `xcolor` package across all major TeX engines (pdfTeX, LuaTeX, XeTeX, and dvipdfmx). It resolves the structural PDF syntax issues found in the legacy `spotcolor` package and provides a more robust, expl3-based architecture compared to the `colorspace` package. Key features included in this initial release: - Native `xcolor` integration: `\textcolor` generates true spot color separation plates in pdfTeX and LuaTeX without breaking the color stack. - Safe fallback for dvipdfmx: `\textcolor` safely falls back to a CMYK representation, avoiding parse errors and black-box outputs. - Explicit spot color injection: Added the `\SpotColor` macro to force true spot color output in dvipdfmx and other engines. - Perfect PDF structure: Safely expands variables and manages PDF objects to prevent garbage collection issues and broken cross-references. - Backward compatibility: Seamlessly emulates legacy `spotcolor` macros (e.g., `\AddSpotColor`, `\NewSpotColorSpace`) to reuse existing color dictionaries without modification. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/spotxcolor More information is at https://www.ctan.org/pkg/spotxcolor ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: expltools
by CTAN Announcements 11 Mar '26

11 Mar '26

Vít Starý Novotný submitted an update to the expltools package. Version: 2026-03-10 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: ---------------------------------------------------------------------- ## expltools 2026-03-10 ### explcheck v0.18.1 #### Fixes This version of explcheck has fixed the following problems: - Merge consecutive blocks of function (variant) definitions and function undefinitions into macro-statements that form flow-graph vertices instead of individual statements. (suggested by @lostenderman in #156, fixed in #183) This change improves processing time by about 10% for an average package file in TeX Live 2024, and by up to 98% (or 53×) for large files such as `expl3-code.tex` when flow analysis is enabled despite incomplete code understanding. It also reduces the memory footprint of flow analysis by up to 3× for those files. After this change, the default value of the Lua option `max_reaching_definition_inner_loops` has been reduced from 30,000,000 to just 650,000 inner-loop iterations. - Fix the assignment of segment numbers to replacement texts. (#183) This would cause function definition statements to point to segments other than the replacement texts, confusing the flow analysis. This change reduces processing time by about 2% for an average package file in TeX Live 2024, and by up to 11% for large files such as `expl3-code.tex` when flow analysis is enabled despite incomplete code understanding. - Raise an error on ambiguous uses of `--long-option VALUE`, where `VALUE` is a valid command-line option. (contributed by @muzimuzhi in #185 and c48fa116) #### Docker image This version of explcheck has made the following changes to our Docker image `ghcr.io/witiko/expltools/explcheck`: - Replace Lua 5.3 with LuaJIT in `Dockerfile`. (#184) This change improves processing time by about 33% for an average package file in TeX Live 2024, and by up to 61% for large files such as `expl3-code.tex` when flow analysis is enabled despite incomplete code understanding. #### Continuous integration This version of explcheck has made the following changes to our continuous integration: - Run regression tests on different Lua interpreters: Lua 5.2, 5.3, 5.4, LuaTeX, and LuaJIT. (#184) - Bump `docker/login-action` from 3 to 4. (contributed by @dependabot in #186.) Overall, the changes in this release reduce the processing time for large files such as `expl3-code.tex` from months to hours (up to 65×) when flow analysis is enabled despite incomplete code understanding, and reduce the memory footprint of flow analysis by up to 3× for those files. While this is still insufficient for real-time use (e.g., in a language server; see ticket #68), it makes the tool practical for scenarios such as continuous integration. For a discussion of other potential performance improvements of the flow analysis, see ticket #156. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/expltools The package’s files themselves can be inspected at https://mirrors.ctan.org/support/expltools/ ---------------------------------------------------------------------- Thanks for the upload.
