HubSpot Marketplace Now Enforces Supported App Versions
HubSpot's announcement from 7 May sets 2 November 2026 as the start of supported developer-platform version enforcement for Marketplace listings and certification. New listings built on legacy apps or on Projects 2023.2 or 2025.1 will be rejected, and apps going through certification or recertification get roughly 60 days to migrate to a supported version such as v2025.2 or v2026.03. It is not a blanket shutdown of existing HubSpot integrations.

Both are effective-date milestones, not new launches.
