Dear Users,

I have released version 4.45 of stunnel.

The ChangeLog entry:

Version 4.45, 2011.10.24, urgency: LOW:
* New features
   - "protocol = proxy" support to send original client IP address to  
     This requires accept-proxy bind option of haproxy 1.5-dev3 or  
   - Added Win32 configuration reload without a valid configuration  
   - Added compatibility with LTS OpenSSL versions 0.9.6 and 0.9.7.
     Some features are only available in OpenSSL 1.0.0 and later.
* Performance optimizations
   - Use SSL_MODE_RELEASE_BUFFERS if supported by the OpenSSL library.
   - Libwrap helper processes are no longer started if libwrap is  
     in all sections of the configuration file.
* Internal improvements
   - Protocol negotiation framework was rewritten to support additional
     code to be executed after SSL_accept()/SSL_connect().
   - Handling of memory allocation errors was rewritten to gracefully
     terminate the process (thx to regenrecht for the idea).
* Bugfixes
   - Fixed -l option handling in stunnel3 script (thx to Kai Gülzau).
   - Script to build default stunnel.pem was fixed (thx to Sebastian
