Release Notes

jstedfast/MimeKit (MimeKit)

v4.17.0

Compare Source

• Added a Received header parser.
• Marked HtmlToHtml.FilterHtml as obsolete to warn developers that this feature is not enough to protect
  against Cross-Site Scripting (XSS) vulnerabilities.
• Fixed logic for calculating maxOffset for Base64Encoder's hwaccel routines.
  (issue #​1239)
• Capped the maxLineLength at 76 for Base64Encoder (which is what it used to be capped at until v4.14).
• Changed the default TnefPart mime-type to application/ms-tnef to match O365 Exchange behavior.
• Code quality improvements.
