The JSesh fonts evolve from time to time. I will try to release catalogues like the one for Jsesh 7.5.5 I have released at Zenodo.
But catalogue don't allow one to track evolution in the individual signs in an easy way.
So, I have automated the process of sign comparison. If you select the Sign Differences Across Versions menu, you will get a list of sign differences between JSesh versions.
Currently, they are just a list of signs, but I will probably take advantage of the system to add a small discussion of the changes when relevant.
Those pages also gives you access to the modified signs in SVG, both those in the new version, and those in the old version, if you want to keep them.
