What changed since a date
Give a date, get every change the ledger recorded since then: price changes with old and new price, new models and plans, retirements that a provider's own lifecycle page dates (Azure VM and AWS Bedrock only; other providers not parsed), and removed plans. Each row has the date we first saw it and a link to the provider's page. The record begins 2024-01-06; nothing earlier is claimed. List prices, not transacted prices.
