CTAN update: quantumcubemodel
by CTAN Announcements via ctan-ann 09 Jan '26

09 Jan '26

Cedric Schacht submitted an update to the quantumcubemodel package. Version number: 0.2.0 2025-12-09 License type: mit Summary description: Representation of quantum states in the quantum cube model Announcement text: ---------------------------------------------------------------------- Dear users, Version 0.2.0 of the `quantumcubemodel` LaTeX package brings significant improvements and introduces breaking changes compared to v0.1.0. Please read below to understand the impact and new features. # Why the Change? This update is the result of a major redesign of the package API, aiming to offer far greater flexibility for users and enable more refined and customizable quantum cube diagrams. The new design exposes the underlying TikZ canvas, allowing for advanced diagramming and more versatile usage quantumcubemodel-doc.pdf. # Key Breaking Changes * API Overhaul: * All user commands now use the qcmx prefix. * Previous commands (e.g., \qcmQ, \qcmQQ, \qcmQQQ) have been replaced by a new environment (qcmx) and rendering commands such as \qcmxRenderQ, \qcmxRenderQQ, \qcmxRenderQQQ. * Amplitude and Phase Configuration: * New commands for setting amplitudes and phases (e.g., \qcmxO, \qcmxI, etc.). * Optional phase parameter (degrees, 0–360) for amplitude commands. * Qubit Axis Control: * You can now set the orientation/axis for qubit systems, with options for 1, 2, and 3 qubits (e.g., \qcmxOrientationQ{y}, \qcmxOrientationQQ{xy}). * Multiple Diagrams in One Canvas: * Support for offsets (X, Y, Z) to position multiple diagrams within one TikZ figure. * Transformation & Measurement Commands: * Specialized render commands for Pauli-X, Y, Z, Hadamard, CNot, CCNot, and measurement operations, with flexible orientation and multi-qubit support. # Migration Guide * Update all usage to the new qcmx environment and commands. * Refer to the new documentation for updated examples and migration instructions. * Legacy commands from v0.1.0 are not compatible; you must adapt your documents to the new API . # New Features * Main color setting for diagrams. * Easier amplitude and phase handling. * More refined control over diagram composition and transformation. * Expanded documentation with practical examples. For further details, consult the documentation and example files included with the package. If you have questions, please reach out.

CTAN update: colorblind
by CTAN Announcements via ctan-ann 07 Jan '26

07 Jan '26

Simon Pfahler submitted an update to the colorblind package. Version number: 1.2 2026-01-06 License type: lppl1.3c Summary description: Easy colorblind-safe typesetting Announcement text: ---------------------------------------------------------------------- In colorblind-safe documents, the contents are presented in a way that the same information is conveyed to readers regardless of a potential color vision deficiency. This package provides the tools necessary for colorblind-safe typesetting in LaTeX. This release adds a warning when one of the standard colors is used that the package redefines to black. Additionally, CMYK definitions for all colors are provided and are used depending on the color model. These additional definitions are only added because they are necessary in some edge-cases and should not be needed by normal users, regardless if they create documents for displays or print. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/colorblind More information is at https://www.ctan.org/pkg/colorblind ------------------------------------------------------------------------ Thanks for the upload.
