What changed, and when
Tax rules change, exchanges change their files, and we fix things. Every change that can affect a figure in your report is dated here, alongside the official rule changes the calculators reflect.
Each report is stamped with the rules version and price method it used, so if you generated a report before a change listed here, you can tell whether it’s affected. Entries marked “Rule change” describe changes made by a tax authority and link to the official source; the others are changes we made.
