@ -98,6 +98,9 @@ porting:
fixed sa_family_t compile error on DragonFly. Thanks to Tony Young for
reporting this issue and sending a patch.
Ubuntu Oneiric: OpenSSL no longer provides SSLv2 functions; libutil.sh
is now bsd/libutil.h; compiler warns on vars that is only written to
new features:
added option max-children that limits the number of concurrent child
processes. Thanks to Sam Liddicott for providing the patch.
