Dear Users,

I have released version 4.54 of stunnel. The ChangeLog entry:

Version 4.54, 2012.10.09, urgency: MEDIUM:
* New Win32 features
- FIPS module updated to version 2.0.
- OpenSSL DLLs updated to version 1.0.1c.
- zlib DLL updated to version 1.2.7.
- Engine DLLs added: 4758cca, aep, atalla, capi, chil, cswift, gmp, gost,
nuron, padlock, sureware, ubsec.
* Other new features
- "session" option renamed to more readable "sessionCacheTimeout".
The old name remains accepted for backward compatibility.
- New service-level "sessionCacheSize" option to control session cache size.
- New service-level option "reset" to control whether TCP RST flag is used
to indicate errors. The default value is "reset = yes".
- New service-level option "renegotiation" to disable SSL renegotiation.
This feature is based on a public-domain patch by Janusz Dziemidowicz.
- New FreeBSD socket options: IP_FREEBIND, IP_BINDANY, IPV6_BINDANY (thx
to Janusz Dziemidowicz).
- New parameters to configure TLS v1.1/v1.2 with OpenSSL version 1.0.1
or higher (thx to Henrik Riomar).
* Bugfixes
- Fixed "Application Failed to Initialize Properly (0xc0150002)" error.
- Fixed missing SSL state debug log entries.
- Fixed a race condition in libwrap code resulting in random stalls (thx
to Andrew Skalski).
- Session cache purged at configuration file reload to reduce memory leak.
Remaining leak of a few kilobytes per section is yet to be fixed.
- Fixed regression bug in "transparent = destination" functionality (thx
to Stefan Lauterbach). This bug was introduced in stunnel 4.51.
- "transparent = destination" is now a valid endpoint in inetd mode.
- "delay = yes" fixed to work even if specified *after* "connect" option.
- Multiple "connect" targets fixed to also work with delayed resolver.
- The number of resolver retries of EAI_AGAIN error has been limited to 3
in order to prevent infinite loops..
