Version 1.0 Update Notes

The v1.0 release line covers the initial open-source MLegS package and its first metadata and publication maintenance updates.

Version 1.0

Established the modernized and parallelized MLegS codebase for mapped Legendre spectral simulations in radially unbounded domains.
Introduced the current Modern Fortran modules, MPI-enabled distributed scalar operations, spectral transforms, PDE time integrators, vector-field utilities, and executable sample programs.
Added the tutorial notebooks and Jekyll documentation for prerequisites, spectral transformations and operations, time integration, vector fields, and representative scalar and vortical-flow problems.
Added the CMake-based external-library build flow for FFTE, FM, and LAPACK, together with Makefile targets for modules and applications.
Moved the GitHub Pages deployment to the main branch so the documentation follows the open-source release line.

Added and standardized CITATION.cff with the software title, authors, affiliations, ORCID, BSD-2-Clause license, release metadata, and Zenodo DOI 10.5281/zenodo.14976471.
Added the README DOI badge and project image.
This maintenance patch did not change the numerical solver, input format, or documented tutorial commands.

Updated the post-open-source publication entry for transient wake-vortex growth from its arXiv record to the published Journal of Fluid Mechanics article, volume 1014, A16, with DOI 10.1017/jfm.2025.253.
This maintenance patch did not change the numerical solver, input format, or tutorial execution paths.
