October 2026: one headline number

The Atlas news log documents 69 source-dated entries in October 2026.

Selected documented entries, not a count of newly announced projects, operating buildings or all developments. Publication, review and scheduled event dates have different meanings.

Calculation: Count distinct entry IDs whose source publication date falls in this month and is no later than the snapshot date, with a retained source URL.
