Blat v3.2.4 has been released

What’s new / changed with this version:

3.2.4
[-] Changed X- header processing to use Buf definition rather than a fixed
array.  The change is made to organization and aheaders, to prevent memory
overruns.
[-] If using alternate text, such as when sending plain text and HTML, and
if that alternate text is Unicode, be sure to set the charset for the
alternate text section and set Content-Transfer-Encoding: 7BIT or 8BIT as
needed and available.
[-] If the message body charset is UTF-8 or UTF-7, and MIME is expected, set
Content-Transfer-Encoding: 7BIT or 8BIT as needed and available instead of
setting Content-Transfer-Encoding: quoted-printable.  The Unicode message
body can then be sent as-is, if 8-bit is allowed, or sent as UTF-7 if 8-bit
is not available from the server.
[-] Ensure message headers are properly sent when sending multiple
attachments across multiple messages, and the charset is UTF-8 or UTF-7.
[-] Ensure the closing boundary marker is sent, when needed.
