Today, Adobe announced that effective immediately, users will no longer be able to download or distribute packages that include versions of Creative Cloud software that are older than the two most recent releases.
Users running the most up to date versions of Creative Cloud apps or older perpetual licenses (ie CS6) are not affected.
Those who use the unauthorized versions of Creative Cloud may be at risk of copyright infringement by third parties. The software will continue to function, but Adobe says users will no longer have third-party claim coverage.
How do I know if I need to update?
Adobe recommends updating if you are using one of the infringing versions of the software as seen in the table.
