Release Notes: Support for the SGI Irix operating system was added. The format of syslog messages was slightly changed to be RFC 3164 compliant.
Release Notes: Tamper detection code was added to endlogging(). The deletion of log files during a session is now recognized. A bug that caused random core dumps under HP-UX was fixed. Conditional compilation was implemented in basename.c for Cygwin. Many comments were added to the code.
Release Notes: A new --with-linenumbering option was added to the configure script, which adds a line count prefix to lines sent to a syslog server. Consecutive numbering from 000 to 100 can be used as a prove that no syslog output was dropped or lost on the way to the syslog server. The session identifier is now the 4-digit hex representation of the process ID. Together with a timestamp it is used as the logfile name. On the syslog server there still may be colliding session identifiers, but together with the hostname they are unique. A new -V parameter that shows the features compiled in was implemented.
