5.2128 Jul 2015 09:05 minor feature: New features.. Signal names are displayed instead of numbers. First resolve IPv4 addresses on passive resolver requests. This speeds up stunnel startup on Win32 with a slow/defunct DNS service. The "make check" target was modified to only build Win32 executables when stunnel is built from a git repository (thx to Peter Pentchev). More elaborate descriptions were added to the warning about using "verify = 2" without "checkHost" or "checkIP". Performance optimization was performed on the debug code.. Bugfixes.. Fixed the FORK and UCONTEXT threading support. Fixed "failover=prio" (broken since stunnel 5.15). Added a retry when sleep(3) was interrupted by a signal in the cron thread scheduler.

A warning was added to stunnel.init if no pid file was specified in the configuration file (thx to Peter Pentchev). Optional debugging symbols are included in the Win32 installer. Documentation updates.. Bugfixes.. Signal pipe reinitialization added to prevent turning the main accepting thread into a busy wait loop when an external condition breaks the signal pipe. This bug was found to surface on Win32, but other platforms may also be affected. Fixed removing the disabled taskbar icon. Generated temporary DH parameters are used for configuration reload instead of the static defaults. LSB compatibility fixes added to the stunnel.init script (thx to Peter Pentchev).

Log file is reopened every 24 hours. With "log = overwrite" this feature can be used to prevent filling up disk space. Temporary DH parameters are refreshed every 24 hours, unless static DH parameters were provided in the certificate file. Unique initial DH parameters are distributed with each release. Warnings are logged on potentially insecure authentication. Improved compatibility with the current OpenSSL 1.1.0-dev tree: removed RLE compression support, etc. Updated stunnel.spec (thx to Bill Quayle).. Bugfixes.. Fixed handling of dynamic connect targets. Fixed handling of trailing whitespaces in the Content-Length header of the NTLM authentication. Fixed --sysconfdir and --localstatedir handling (thx to Dagobert Michelsen).

5.1518 Apr 2015 04:25 minor feature: New features: Added new service-level options "checkHost", "checkEmail" and "checkIP" for additional checks of the peer certificate subject. These options require OpenSSL version 1.0.2 or higher. Win32 binary distribution now ships with the Mozilla root CA bundle. This bundle is intended be used together with the new "checkHost" option to validate server certs accepted by Mozilla. New commandline options "-reload" to reload the configuration file and "-reopen" to reopen the log file of stunnel running as a Windows service (thx to Marc McLaughlin). Added session persistence based on negotiated TLS sessions. https://en.wikipedia.org/wiki/Load_balancing_ 28computing 29#Persistence The current implementation does not support external TLS session caching with sessiond. MEDIUM ciphers (currently SEED and RC4) are removed from the default cipher list. The "redirect" option was improved to not only redirect sessions established with an untrusted certificate, but also sessions established without a client certificate. OpenSSL version checking modified to distinguish FIPS and non-FIPS builds. Improved compatibility with the current OpenSSL 1.1.0-dev tree. Removed support for OpenSSL versions older than 0.9.7. The final update for the OpenSSL 0.9.6 branch was 17 Mar 2004. sessiond" support improved to also work in OpenSSL 0.9.7. Randomize the initial value of the round-robin counter. New stunnel.conf templates are provided for Windows and Unix.. Bugfixes. . Fixed compilation against old versions of OpenSSL. Fixed memory leaks in certificate verification.
5.1426 Mar 2015 17:45 security: Security bugfixes. The "redirect" option now also redirects clients on SSL session reuse. In stunnel versions 5.00 to 5.12 reused sessions were never redirected regardless of their certificate verification result. New features: Windows service is automatically restarted after upgrade. Bugfixes: Fixed a memory allocation error during Unix daemon shutdown. Fixed handling multiple connect/redirect destinations. OpenSSL FIPS builds are now correctly reported on startup.

5.0702 Nov 2014 03:16 minor feature: New featuresSeveral SMTP server protocol negotiation improvements. Added UTF-8 byte order marks to stunnel.conf templates. DH parameters are no longer generated by "make cert". The hardcoded DH parameters are sufficiently secure, and modern TLS implementations will use ECDH anyway. Updated manual for the "options" configuration file option. Added support for systemd 209 or later. New --disable-systemd ./configure option. setuid/setgid commented out in stunnel.conf-sample. BugfixesAdded support for UTF-8 byte order mark in stunnel.conf. Compilation fix for OpenSSL with disabled SSLv2 or SSLv3.

A number of minor Win32 GUI bugfixes and improvements. Merged most of the Windows CE patches (thx to Pierre Delaage). Fixed incorrect CreateService() error message on Win32. Implemented a workaround for defective Cygwin file descriptor passing breaking the libwrap support: http://wiki.osdev.org/Cygwin_Issues#Passing_file_descriptors
5.0417 Sep 2014 03:15 minor feature: New featuresSupport for local mode ("exec" option) on Win32. A more explicit service description provided for the Windows SCM (thx to Pierre Delaage). TCP/IP dependency added for NT service in order to (hopefully) prevent initialization failure at boot time. FIPS canister updated to version 2.0.8 in the Win32 binary build. Bugfixesload_icon_default() modified to return copies of default icons instead of the original resources to prevent the resources from being destroyed. Reportedly more compatible values used for the dwDesiredAccess parameter of the CreateFile() function (thx to Pierre Delaage). Partially merged UNICODE compilation fixes (thx to Pierre Delaage).
