Why cite the 2012 paper for a 2020 software? In computational chemistry, it is standard practice to cite the methodology paper (2012) while specifying the software version used (e.g., "Calculations were performed using Multiwfn 3.8" followed by the citation). This gives credit to the creators for the core algorithms while allowing readers to identify the specific bug fixes or features present in version 3.8. Before diving into the download process, it is

Before diving into the download process, it is worth understanding what makes version 3.8 special. Released in late 2019 / early 2020 (depending on the minor revision), Multiwfn 3.8 introduced several key features that stabilized into a mature, bug-free environment:

Many legacy tutorials and PhD theses cite Multiwfn 3.8, making it a required version for reproduction studies. Moreover, some users prefer 3.8 for its stability compared to bleeding-edge releases.

Solution: Ensure your Gaussian .chk file is converted to formatted checkpoint (.fchk) using formchk. Multiwfn 3.8 does not read binary .chk files.
