Full Fact Overview
The transition to a 'Sustaining Engineering' model signifies a strategic pivot for Heroku, moving away from aggressive feature development toward a maintenance-heavy lifecycle. This model is typically employed by mature platforms to prioritize uptime, security patching, and infrastructure reliability over the introduction of new, experimental services. By framing the update around 'stable, secure, and reliable' environments, Heroku is signaling to enterprise customers that the platform is entering a long-term support phase, likely reducing the frequency of breaking API changes or major architectural overhauls.
