Backward compatibility
Making an artwork for some laser wood cutting machines suppose to save as old AI versions, as CS2. No problem with backward compatibity until CC 2019, where all strokes are converted into thin fills.

It happened to every file saved from 26 I tried to open in 25.4.1. After re-installing 25.4.1 it stopped happening. A few days later it happened again with a file very similar to others that work correctly. I don't have this file anymore. If this happens again I will share the file. Thanks

Can you share the file that behaves like this for you?

Illustrator 26 saves files that can not be opened in 25.4.1 although in the dialogue box one can read it is compatible with illustrator 24 and above (while saving in default version, 2020)

Illustrator needs to be able to support older versions.
I have clients running old CS and even Illustrator 6.0, and sometimes need to open ancient files.

Illustrator 2020 appears to have sacrificed backwards compatibility with even Illustrator 2019. This change is detrimental to working across teams on large scale projects.
