Corrections log
Substantive corrections to CrawlerBros pages, with the date, the page, what changed, and the source. Typo fixes are not logged.
This log records substantive corrections: changes that alter what a reader would conclude, a code sample that no longer works, a fact that was wrong, or a source that was misread. Typo fixes, broken-link replacements, and formatting changes are made without an entry.
If you find an error, email corrections@crawlerbros.com with the URL and the source that shows the correct version. See the editorial policy for how corrections are handled.
Correction log
No substantive corrections have been logged since the relaunch on 2 November 2026. This is a new site; an empty log is the honest state, not a claim that nothing will ever be wrong.
When an entry is added, it will look like this:
| Date | Page | What changed | Source |
|---|---|---|---|

Site changes (not corrections)
These are structural changes, recorded so the history is clear:

How to report a problem
- Check the page’s last updated date.
- Send the URL, the exact sentence or code, and a link to the primary source.
- If the issue is a security problem, say “security” in the subject and do not test against data you do not own.
- If the issue is accessibility, include the browser and assistive technology you used.
We aim to acknowledge substantive reports within five working days.
