The latest release of SFTPPlus, version 4.29.0, is now available.
This release fixes an important defect for FTP/FTPS transfers which fail during the authentication process. This was a regression introduced with version 4.28.0.
Version 4.29.0 also allows starting SSL-/TLS-based services and transfers associated with Certificate Authorities configured with expired certificates. The expired certificates are now ignored, no longer causing start failures.
