This is a Beta version. Confidant Mail with GPG 1.4 has been stable. The code has supported GPG 2.1 for the past several versions, but this is the first release bundled (Windows, Mac) with GPG 2.1.21 instead of GPG 1.4. There may be some surprises, because GPG 2.1 is very different in how it handles passphrases. The testers using v0.38 ran into passphrase timeout problems, which have been handled in v0.39.

• Added support for gpg 2.1.22 on 2017-08-05
• Please report any bugs via the forum or CM me at

• You can install this version on Windows over v0.38, but if you want to return to v0.38, please uninstall v0.39 before installing v0.38.
• Arch Linux works with source release and OS bundled gpg 2.1
• Ubuntu 16.04 and Linux Mint work with the .deb package and OS bundled gpg 2.1
• You can create ECC keys, but they are not compatible with GPG 1.4. ECC keys are for testing in closed groups at this time. You cannot contact me using an ECC key. My public servers do now accept ECC keys.
• GPG 2.1 eventually times out the passphrase in memory, at which time auto-fetch will stop working unless you type the passphrase again. Manually performing a check-send will cause the passphrase prompt to reappear and auto-fetch will resume if it was enabled.
• There are no new features, so if you are not interested in trying GPG 2.1, there's no need to upgrade right now. I did not trigger the upgrade notification in earlier versions.
