Data & Site Changelog
Changes to public data and calculations are recorded here.
October 1, 2026: initial verified dataset
Added BLS CPI-W through August 2026, official 2024-2026 SSA and CMS amounts, the 2026 Medicare Trustees projections, annual rule-generated payment schedules through 2028, and source-linked benefit and retirement calculators. The 2027 COLA is provisional; the September observation is missing.
October 2, 2026: verification updates
Identified the already official 2027 Part D base benchmark, deductible and drug-spending cap; kept future Part A/B and IRMAA projections separate. Corrected military monthly-pay rounding and historic RMD starting ages, and labelled the 1959 cohort assumption. Added keyboard focus handling, query privacy protections and a self-hosted Manrope font with its open-source license.
Projection policy
2027-2028 thresholds and surcharges are labelled where assumption-based. The annual promotion tools require an official government source and date, verify the candidate data, purge the relevant cache and rebuild sitemaps.
