This release fixes a bug in pid creation. If a user specified -P /dirname
instead of -P /dirname/ stunnel would assume that it's a file, delete it and
create a new one. Now stunnel makes sure if it's really a file.
Version 3.9, 2000.12.13:
* Updated temporary key generation:
- stunnel is now honoring requested key-lengths correctly,
- temporary key is changed every hour.
* transfer() no longer hangs on some platforms.
Special thanks to Peter Wagemans for the patch.
* Potential security problem with syslog() call fixed.
