What happened
Between the Dec 29, 2025 and Mar 30, 2026 captures of Langfuse's pricing page, Pulse recorded 2 changes: Enterprise contracts section updated: 'Custom with Yearly Commitment' replaced by 'Talk to Sales'; Custom Terms & DPA removed from Yearly Commitment add-on bullet points; Pro and Enterprise plan data access reduced from Unlimited to 3 years. Previously both plans offered unlimited historical data access. Pulse files it as a packaging change (positioning, limit decrease) with a downward direction.
