AWS acm documentation change
Summary
Added two document history entries: 1) ECDSA Key Usage exception for certificate reimport (compliance with RFC 5480), 2) SearchCertificates documentation update.
Security assessment
The ECDSA Key Usage exception change addresses a compliance issue with RFC 5480 standards for certificate validation, which has security implications for certificate handling. However, this appears to be a standards compliance update rather than fixing a specific security vulnerability. The SearchCertificates entry is a routine documentation update.
