CTAN update: CircuiTikZ
by CTAN Announcements via ctan-ann 27 May '26

27 May '26

Romano Giannetti submitted an update to the CircuiTikZ package. Version number: 1.8.6 2026-05-24 License type: lppl gpl Summary description: Draw electrical networks with TikZ Announcement text: ---------------------------------------------------------------------- A shiny new style for the manual, with a new example code implementation by Jonathan P. Spratte, based on the package `enverb`. The manual now avoids writing *hundreds* of auxiliary files, and compiles significantly faster. As a bonus, now the manual can be compiled with `lwarp`, enabling the creation of a pure-HTML version. Additionally, a new option to simplify building custom blocks, thanks to a suggestion by Matthias Jung. - New manual style, with new example code based on `enverb` (mainly by Jonathan P. Spratte) - New option `border` for `component text` that applies to the `twoportsplit` component - New option `jfet gate height` to move the vertical position of JFET gate - New options for relative gate thickness in FETs and MOSFETs, and rounded caps for transistors - Fixed a nasty bug with `ooosourcetrans`. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/pgf/contrib/circuitikz More information is at https://www.ctan.org/pkg/circuitikz ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: numodel-bundle

Paul Zuurbier submitted an update to the numodel-bundle package. Version number: 0.6.0 2026-05-26 License type: lppl1.3c Summary description: Numerical physics models with Forrester diagrams and auto-sized plots Announcement text: ---------------------------------------------------------------------- numodel-bundle v0.6.0 Highlights ---------- * New per-prefix accessor \<prefix>steps expands to the iteration count N after \computemodel. No more deriving N by hand from Tmax/dt. * \mstep{<Name>}{<i>} now raises a numodel error when <i> is outside the recorded range, instead of silently expanding to nothing. * \textmodel: alias keys (alias, aliasleft, aliasright) now work with amsmath dots macros (\cdots, \ldots, \dotsb, ...). Fixes a regression introduced in v0.4.0 by the tabularray migration. * \graphicmodel auto-layout no longer leaves an empty row between the stocks row and the constants row when the model has no auxiliary variables. Build / packaging changes ------------------------- * The user manual moved out of the .dtx into stand-alone numodel-manual.tex / numodel-plot-manual.tex. The .dtx is now pure docstrip source. Manuals use Arial + Lete Sans Math + Fira Mono and a tcolorbox+listings example environment so each example is shown verbatim and executed from a single source. * The examples/ directory is no longer shipped to CTAN. Removed ------- * numodel: stockwidth setup key and \halfstockwidth macro (dead code). See numodel/CHANGELOG.md and numodel-plot/CHANGELOG.md for the full list. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/luatex/latex/numodel-bundle More information is at https://www.ctan.org/pkg/numodel-bundle ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: pkgcheck
by CTAN Announcements via ctan-ann 27 May '26

27 May '26

Manfred Lotz submitted an update to the pkgcheck package. Version number: 4.0.2 2026-05-25 License type: apache2 mit Summary description: CTAN package checker Announcement text: ---------------------------------------------------------------------- ## pkgcheck 2026-05-25 (4.0.2) ### Fixed Fix filecontents false positives Suppress \begin{filecontents} targets in files that have no \generate or \generateFile commands. Such files use filecontents for documentation purposes (embedded code examples, index-style files written during doc compilation) rather than for package installation. Co-Authored-By: Claude Sonnet 4.6 <noreply(a)anthropic.com> ## pkgcheck 2026-05-24 (4.0.1) ### Fixed Fix three parser bugs in nom_parsing.rs - keep may_generate=true when a macro is redefined with a non-generating body (sticky flag). Fixes ctable/isodoc where \ifx...\else...\fi guards a generating and a no-op \def of \Extract. - introduce skip_control_symbol so the fallback branch advances past \X (backslash + one character) rather than just the backslash. Fixes \\begin{filecontents} and \\generate{ in Perl string literals (perltex.dtx, makedtx.dtx) being misread as real TeX commands.

New on CTAN: orbitals
by CTAN Announcements 27 May '26

27 May '26

Faris Hameed submitted the orbitals package. Version: 1.0 License: lppl1.3c Summary description: Atomic subshell / orbital-box diagrams for LaTeX, with automatic electron filling following Hund's rule and the Pauli principle Announcement text: -------------------------------------------------------------------------------- `orbitals` draws the familiar "box-and-arrow" notation for atomic subshells (s, p, d, f). You give only the principal quantum number, the subshell letter and the number of electrons; the package fills the boxes automatically (one spin-up arrow per box first, then pairing), reproducing the high-spin free-atom ground state. It can draw: * a single subshell (`\suborbital`), * a row of subshells (`\electronconfig`), * a valence configuration with a noble-gas core (`\atomconfig`), * an empty transition-series template (`\transitionseries`). Every diagram can be scaled and placed inline in running text. Colours, box size, spacing and arrow shape are configurable. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/pgf/contrib/orbitals More information is at https://ctan.org/pkg/orbitals -------------------------------------------------------------------------------- Thanks for the upload.
