Enigmail 1.5

Version 1.5:

  • PGP/MIME encryption & signing have been rewritten from scratch in JavaScript.
  • Core parts of inline-PGP (creation, decryption and verification) have been rewritten in JavaScript.
  • Due to the new code structure, this version of Enigmail is compatible with all future versions of Thunderbird and SeaMonkey. There is a small C++ component remaining for Thunderbird 17 and 18 and SeaMonkey 2.14 and 2.15. As of Thunderbird 19 and SeaMonkey 2.16 there won't be any Mozilla version-specific code in Enigmail.
