Background: I share my program, m2uml, at the Matlab File Exchange. m2uml creates a PlantUML class diagram script based on MATLAB source code. PlantUML takes the script and outputs an svg-file. A MATLAB internal viewer displays the class diagram. The diagram features both MATLAB specific hyper-links and tooltips. I use the triple bracket syntax, "[[[". This has worked well since hyperlinks was introduced in PlantUML. The MATLAB internal viewer correctly displays the PlantUML version 1.2018.09 svg-files. Both the hyperlinks and the tooltips works well. However, with PlantUML version 1.2019.07 the hyper-links "are gone". The pointer doesn't turn into a hand and there is no visible response to left-clicking. The svg-files generated by the two versions, 1.2018.09 and 1.2019.07, reveal differences when displayed in a text editor.
I assume that my problem is caused by limitations of the MATLAB internal viewer.
Questions: Is it possible to download older PlantUML versions from the PlantUML website? I have asked users to download from your website. If not, I assume I can describe the reason and attach plantuml.1.2018.09.jar to my m2uml.
