PuTTY CAC 0.84
This release merges upstream PuTTY 0.84 changes and includes PuTTY CAC specific changes. This release was compiled with Microsoft Visual Studio 2026.
Enhancements:
- Added a portable mode. This can be enabled by creating an empty putty.dat file in the same directory as the executable. The PuTTY user interface also contains a new root-level 'Portable' pane that can be used to export current settings to the file. This file makes all PuTTY registry settings portable (not just PuTTY CAC specific settings).
- Changed Windows cryptographic algorithm usage to attempt CNG APIs and fallback to CAPI APIs.
Changes:
- Updated to latest FIDO2 libraries.
- Numerous minor bug fixes.

PuTTY CAC 0.81
This release merges upstream PuTTY 0.81 security changes and includes several PuTTY CAC specific changes. This release was compiled with Microsoft Visual Studio 2022.
Enhancements:
- Added the ability to override user registry settings by setting like-named registry values under HKLM\Software\SimonTatham\PuTTY. This can allow administrators to turn off specific settings like PIN caching.
Changes:
- Changed parent window for credential prompts to use the desktop window thereby causing the window to produce a taskbar-accessible icon. This can help the user locate the window if they had changed focus during the authentication process.
- Addressed issue where PKCS mode may not properly pass PINs with multibyte characters to the token.
- Addressed issue where PKCS mode may not honor PIN caching setting.
- Addressed issue where PKCS mode login failure could crash Pageant.

PuTTY CAC 0.80
This release merges upstream PuTTY 0.80 changes and includes two PuTTY CAC specific enhancements. This release was compiled with Microsoft Visual Studio 2022.
Enhancements
- Added the ability to set of display name when creating a FIDO key. This field is not used in PuTTY CAC operations but can be useful for distinguishing keys in applications like Yubico Authenticator.
- Added the ability to ignore any certificates that have a specific subject name from autoloading or being available in the certificate selection dialog boxes. You can set this creating a registry; an example is provided below:
REG ADD "HKEY_CURRENT_USER\Software\SimonTatham\PuTTY" /F /V IgnoreCertName /T REG_SZ /D "StringToIgnore"
