Leafnode

This release detects timeouts while downloading the header (to avoid denial of service, CAN-2005-1911). A bug in the makesubst sed script was fixed. debug mode and verbose print a warning that the user should check syslog. texpire tags the message.id expiry counts with "message.id", not "total", to disambiguate. The documentation was polished a bit.

Two segfaults that could be triggered by a
malicious upstream server, potentially causing
denial of service, have been resolved. fetchnews
is more careful about when to re-fetch the active
file (fixing Debian bug #70052). Two missing lines
in the German leafnode(8) manual page have been
restored.

Pluralization bugs in leafnode messages have been fixed. The
documentation (including Internet addresses) has been revised. A Solaris
portability fix has been added.

fetchnews supports IPv6. The configuration parser understands quoted strings on the right-hand side, so you can use # et al. in passwords. The snprintf test was corrected, saving some program code on systems with intact snprintf.

This release keeps interesting groups interesting on LIST ACTIVE and GROUP client commands, even if they are empty. It avoids premature unsubscription from groups.
