Release Notes for 6.7.1

Due to a bug in the Tika library, .pfx and .p12 files are detected as application/x-x509-key instead of application/x-pkcs12.

To handle this, .pfx and .p12 files will be allowed if:

1. .pfx or .p12 is in the allowlist

2. The detected base MIME type is application/x-x509-key
