Changelog

Updates

Every change to fee data, tax bands, calculators, or content is recorded here. An audit trail for the numbers you depend on.

Last updated 25 April 2026

How this works

When a platform changes its fees, when IRS publishes new tax bands, when a calculator gets a new feature, when a reader spots a bug — every change shows up here, with the date and a one-line summary.

This isn’t a marketing blog. It’s an audit trail. Most weeks there’ll be nothing to report. When there is, you’ll find it here first.
