Corrections
Whatever gets changed is recorded here, with the date, the place and the substance of the change. Published entries stay.
What this page is for
When something is wrong, imprecise, or no longer matches reality, we fix it and record the change here — the date, the location, and what changed. Entries are not removed.
Two reasons for doing it this way: readers can see what has changed, and it constrains us. An error that has been written down cannot be treated as though it never happened.
Log
Only corrections to the content itself go here — something we got wrong, stated imprecisely, or that no longer matches reality. Redesigns, domain changes and new features are site admin, not corrections.
2026-08-28 · A tool page described its data source as "live"
The first draft of the volatility gauge said "live market data", but the implementation makes a single request when the page opens and does not refresh afterwards. Those are not the same claim. Change: the copy now says the data is fetched once when the page opens and does not auto-refresh, and the tool notes explain that a failed request displays nothing at all, because no figures are stored in advance.
Known issues, not yet resolved
None at the moment. This section is not kept as an empty formality — anything new gets written back into it.
