	- Fixed unfortunate misprint in --with-pcap handling.

2003-01-07  Slava Astashonok <[e-mail]>

	* Release 1.0.pre1:
	- New features, minor fixes.

	* Changes:
	- Daemonize done. The default behaviour of fprobe now is run
	  in background. Note that if log destination contains `stdout'
	  (equal 2 or 3) fprobe will run in foreground.
	- Default log destination changed to syslog.
	- Now fprobe catch SIGTERM signal and emit flows cache before exit.
	- Changed --enable-debug arguments. Now valid arguments are
	  C, U, S, E, M, F and I. Example: --enable-debug="C M I E" -
	  enable Capture, Memory, Info and Emit debug messages.
	  "I"-debug information accessible via SIGUSR1 signal.
	  Note that SIGUSR1 will cause program termination if it
	  compiled without --enable-debug="I".
	- Manpage updates.

2002-12-19  Slava Astashonok <[e-mail]>

	* Release 0.91:
	- Bugfixes, new features.

	- Fixed snmp_index typo, sorry.
	- Fixed potential flaw with non-realtime scheduling.

	* Misc:
	- New options:
	  -a Now possible to specify source address for NetFlow flow.
	  -t Emitting rate limit. Used relatively silly way.
	- Internal time resolution changed from miliseconds to microseconds.
	- ToS field support added. Why it wasn't done early? :-/
	- At last added TCP flags field support.
	- Added RPM specfile.
	- Manpage updates.

2002-12-09  Slava Astashonok <[e-mail]>

	* Release 0.90.1:
	- Typo in usage() information

2002-12-08  Slava Astashonok <[e-mail]>

	* Release 0.90:
	- The main goal of this release is perfomance improvement.
	  Almost all was rewrited from this point of view.
	- It seems version 1.0 it is not far, so I made big jump in
	  version enumeration.

	* Perfomance fixes:
	- Hash size expanded from 8 to 16 bits.
	- New fast and efficient memory subsystem.
	- Realtime scheduling.

	* Bugfixes, portability fixes:
	- Correct ctime updating after packet "reassembling".
	- NETFLOW_SRC_AS_SIZE and NETFLOW_DST_AS_SIZE in netflow.h was wrong.
	  Previous versions unaffected to this bug.
	- Handling RedHad's pcap.h location.

	* Misc:
	- Changed -e option sense - now it equivalent to Cisco's active timer.
	- Added new hash types: xor16 and crc16.
	- New options:
	  -x Workaround for SNMP interface index
	  -b Memory bulk size in flow entries
	  -m Memory limit in kilobytes
	  -q Pending queue length in flow entries
	  -r Realtime priority
	- New compiling options:
	  --with-pcap=<path> Example: /usr/local/pcap/include
	  --with-libpcap=<path> Example: /usr/local/pcap/lib
	  --with-membulk=<mode> ptr - less efficient, but fastest
	  --with-hash=<type> crc16 - slowest, but smooth
	  --enable-messages Enable runtime error and warning messages
	- Added simple script for stress tests: contrib/tg.sh
	- Manpage updates.

2002-11-08  Slava Astashonok <[e-mail]>

	* Release 0.9:
	- Bugfixes, portability fixes, code cleanup
	- New option -z for timezone correction
	- New data link layer types: DLT_IP_OVER_FC and DLT_SUNATM
	- New options in configure script:
	  --enable-uptime_trick: this option may used to solve potential
	  uptime wraparound bug in NetFlow collectors
	  --enable-icmp_trick: if this option enabled fprobe will
	  store ICMP type and code in srcport and dstport fields
	- Manpage updates

2002-10-25  Slava Astashonok <[e-mail]>

	* Release 0.8 (first public release):
	- NetFlow 1, 5 and 7 partially supported:
	  supported fields in header record: version, count, SysUptime,
	  unix_secs, unix_nsecs, flow_sequence
	  in flow record: srcaddr, dstaddr, dPkts, dOctets, First,
	  Last, srcport, dstport
	- Compiled on Linux, FreeBSD, Solaris (all x86)
	- Seems work, but not properly tested
