What actually changed, and when. Dated entries, newest first. Small fixes are grouped; anything that changed a formula or a published figure is listed on its own.
6 September 2026
- The contact form is live. Messages now reach me directly, with spam protection instead of a published email address.
- Corrected the language count shown on the home page and in
llms.txt. It advertised more languages than were actually finished. - Fixed a CSS rule that could stop the navigation bar staying pinned while scrolling.
5 September 2026
- Eleven languages now translate the entire site — English, Spanish, Portuguese, French, German, Polish, Russian, Arabic, Hindi, Simplified Chinese and Japanese. Previously the selector offered far more languages but translated only part of each page.
- Arabic now renders right-to-left properly, including the language selector and navigation.
- Dates, times and numbers inside the calculators now follow the language you pick, instead of always using US English.
4 September 2026
- Fixed the language switcher. Choosing certain languages led to a "page not found" error; it now translates the page you are on, without a reload.
15 August 2026
- Added site-wide navigation and breadcrumbs, so every page is reachable from every other page.
- Fixed a mobile layout bug that let the home page scroll sideways.
- Removed a 3.17 MB unused file from the page load.
28 July 2026
- Removed the placeholder boxes that reserved space for advertising. Empty ad slots now collapse instead of showing a grey rectangle.
14 July 2026
- Published the privacy policy, terms of service and contact page, and linked them from the footer of every page.
- Consolidated the tool URLs so each tool has one canonical address.
