Hi, someone knows which older versions of InDesign are still supported by Adobe?
Thanks for your help.
2023 and 2022 are the only supported and available versions.
The rule is a simple one Adobe supports on the current version and the one prior to it. So that would be 2023 and 2022 for now, as soon as a new major update is out 2022 will drop off the supported list. Now as per your link, it seems to just have detailed information about security updates, however to download and install them you would need to update the app using Creative Cloud desktop app and that would deliver updates only to the latest 2 versions as described above. If you have any older unsupported version of CC app installed you can keep using it without issues.
Hope this clears your queries.
Thanks for your answer! This helps me.
