Effective December 1, 2020, a Long Term Supported (LTS) version for Adobe Creative Cloud is available for enterprise customers. LTS delivers an additional 12 months of security updates beyond the most recent ‘N’ version, which, in combination with N, allows the customer to standardize on a major version for a combined maximum of 24 months.
However, effective February 4, 2021, outdated versions, meaning N-3 and older, are being removed from the Adobe Admin Console and Creative Cloud Desktop App. Adobe will no longer retain versions beyond N-2 for download and will no longer provide support, including security updates, for such versions. Adobe therefore recommends downloading and retaining the installation package in a safe location, if you intend to use an outdated version for an extended time.
