How to read these updates
Each entry groups related work by release date. Product updates usually mean new calculators, better examples, or cleaner navigation. Technical updates usually mean build, sitemap, schema, redirect, accessibility, or performance work. Trust updates cover author information, privacy language, source notes, editorial standards, and corrections.
The changelog is not a marketing timeline. It is a maintenance record for a utility site, so the important question is whether the tools are becoming clearer, safer, faster, and easier to verify over time.
When a page is removed from the sitemap, moved behind a redirect, marked noindex, or expanded with more original context, that change belongs here because it affects what search engines and human reviewers can evaluate. The goal is a smaller, cleaner index of pages that deserve to be found.
Older entries stay visible instead of being rewritten, so it is easier to understand how the project moved from a broad tool directory toward a more careful AdSense-ready site.
