Changelog
Every change that affects what you see or measure, newest first. Each date is when that change shipped.
- Changed the contact address to info@smcs.com.br. It is the same address everywhere it appears — the contact page, both places the privacy policy names it, the terms, and the publisher record search engines read — so a privacy request cannot land in a mailbox we no longer read.
- Fixed the language switcher: on Portuguese pages the EN button sent you back to Portuguese instead of switching. It had been broken since the previous day's navigation work.
- Fixed navigation that pointed at pages which do not exist. The three topic guides in Portuguese linked every tool through a doubled language prefix, so 17 links returned 404; the language switcher did the same on the four Brazil-only tools, and everywhere else it went through a redirect instead of straight to the page.
- Tools that exist only in Portuguese no longer advertise an English version to search engines: their hreflang and x-default pointed at URLs that return 404.
- Added a section explaining how the text on this site is produced, including where AI is used, what it is not allowed to decide, and two technical claims we cut because we could not tie them to a primary source.
- Rewrote the home page around what these tools can and cannot measure, why nothing is stored, and why a failed probe says "unavailable" instead of showing a plausible number.
- The Portuguese home page was still listing the CPF generator among its tools after it was retired earlier the same day. Removed.
- Retired the CPF and CNPJ generators. This was our own call, not a requirement from anyone: we would rather check a number you were given than manufacture a new one. The validator stays, and the BR data generator now returns only name, phone, email and address.
- Rewrote the three per-game ping pages: each one now explains which endpoints it actually measures and why, citing Valve and Riot directly.
- Ten tools gained their own content, written from the code — what counts as one character, the word-splitting rule, what the keyboard and mouse tests can and cannot measure, and why the microphone bar is not decibels.
- The validator page now records that the alphanumeric CNPJ starts on 31 July 2026 and that the tool does not accept the new format yet.
- Added terms of use, and expanded the about and contact pages with what the site does, what it does not, and how to report a wrong result.
- Every page now names who publishes StackNest, with a link to the studio that operates it.
- Removed empty ad placeholders and off-topic partner links from pages where they outweighed the content.
- Every tool page now shows the date its content was last reviewed.
- Published this changelog.
- Ping and speed tests only suggest a fix when the result calls for one — two or more probes above 95 ms, or a slow download.
- Corrected the page language declaration for screen readers and raised the contrast of secondary text.
- New 404 page that suggests popular tools in your language.
- Search no longer reports “1 tool found” when there are none.
- Status colours (good, warning, problem) now match across every tool, in both light and dark themes.
- Speed test reports jitter from eight latency samples, labelled stable, moderate, or unstable.
- VPN leak test shows which DNS resolver answered, with its IP and location.
- Privacy score leads with the score and risk chips; the full signal table starts collapsed.
- Tools that only apply to Brazil no longer appear in the English catalogue.
