AWS documentdb: DocumentDB release notes: security patches and $text bug fix
Summary
Adds September 15, 2026 entries for DocumentDB 8.0.1 and 8.0.0 engine patches (security and stability improvements, a $text underscore residual-filter bug fix), removes '[in progress]' from the August 18 8.0.1 entry, and announces serverless availability in additional Regions.
Security assessment
The entries describe generic 'security and stability improvements' and a query-correctness bug fix, with no CVE, advisory ID, or described vulnerability, so there is no concrete evidence of addressing a specific security weakness.
Evidence
+ 1. Fixed an issue where `$text` search queries containing underscore characters could return incorrect results when evaluated as a residual filter.
