4.0.0

Improved encoding of email headers for key toString() and getEncodedHeaders() methods by using the new Symfony/Mime component.

Public API is largely unchanged, but there are two little-used methods removed, and remaining primary email headers have been given dedicated getters and setters so can no longer be set using addHeader(): Message-Id, (Origination) Date, Received, In-Reply-To and References.

See Change Log for full details.

3.2.1

Fix incorrect 4 spaces added to folded headers. Now only uses 1 as indicated by RFC5322 §2.2.3.

See Change Log for full details.

3.2.0

No longer encode pure-ASCII headers. RFC2047 'encoded-word' syntax is only used when non-ASCII characters are detected.

See Change Log for full details.

3.1.0

Minor fixes for strict typing, ensure default content type is used.

3.0.0

Prevent Message-Id header from being encoded. Message-Id has a specific syntax which does not allow for encoding, so it will always be rendered as provided.

Removed support for PHP 5.x and 7.0 as they are no longer actively supported by the PHP project.

See Change Log for full details.
