How pages are made

Sources first

Every page starts from primary sources: official documentation, certification databases, and official release data and calendars. Each fact on a page links to the source it came from, so you can check it yourself. The data sources the site currently uses, with their licences, are listed on the sources page.

Source text is not copied: facts are summarised in plain words and linked to the original.

How dates are labelled

Every date on the site carries one of three labels:

Scheduled

The date appears in an official calendar or an official announcement.

Expected

The date follows from a published rule, such as “the first Wednesday of the month”, but is not yet in an official calendar.

TBA

Not announced yet. Rumours and leaks are never turned into dates.

Times are shown in UTC, with conversions for several cities. The conversion to your own time zone happens in your browser. Official dates sometimes move; pages with automated data follow their source at the next daily check.

Compatibility answers

Compatibility answers are being added. Each one uses one of four labels and shows the date it was last verified. Answers are re-checked at least every 90 days, and sooner when a source changes.

Yes

Officially supported, either natively or through an official certification.

Partly

Works only for some models or in some regions, or only through a bridge or an extra hub.

No

Not officially supported.

Unknown

No reliable source was found that answers the question.

What this site does not claim

• No hands-on testing claims. Pages are compiled from sources, not from testing devices, and never say otherwise.
• No star ratings, scores or “best” rankings.
• Lists use objective filters, such as a certification, a supported platform or a region, and each list explains its criteria.
• No paid placement: a position in a list cannot be bought.

Automated data and checks

Data that changes often is kept up to date by an automated job that runs once a day; scheduled runs sometimes start a few hours late. The job:

1. fetches each source;
2. validates what it receives: the data must match the expected structure (schema checks) and must not be suspiciously small (size checks);
3. keeps the last good snapshot when a source fails or its data does not pass validation, so a broken source never replaces good data on the site;
4. records the result of each check on the data status page.

If the site cannot be built with the new data, the published version stays as it was.

Corrections and changes

If something is wrong, please write via the contact page with the page address, what is wrong and a source. Confirmed errors are fixed and recorded on the corrections page with the date and what changed. Changes to the site itself, such as new sections, are listed in the changelog.

Use of AI

The site’s code and page drafts are written with substantial help from an AI assistant, Claude, made by Anthropic. This is how the published pages are kept accurate:

• Facts come from the linked sources, and each one links to where it can be checked.
• Automated checks validate the data before it is published.
• The site owner publishes every page and is responsible for it.
• Errors are corrected publicly on the corrections page.
