17- testing version, 0.8 will be stable release

3b267509 21version 0.7 2007-01-29
a4f661fc 22
23- There were good reasons to rename iptables hashing to iptables indexing.
24 Hashing is different algorithm, which offers constant complexity
25 independent on number of hashed entries and high memory requirements, while
26 iptables indexing used in Prometheus offers log8(N) complexity and relatively
27 low memory requirements compared to hashing.
28- Multiple keywords can be defined and used in /etc/hosts-like nodelist,
29 which allows definition of various data limits for different users or
30 definition of both symetrical and asymetrical virtual lines in same config.
31- Following prometheus.conf variables were made keyword-dependent:
32 KEYWORD-magic-relative-limit, KEYWORD-magic-relative-prio,
33 KEYWORD-magic-fixed-limit, KEYWORD-magic-fixed-prio, KEYWORD-,
34- Following new prometheus.conf keyword-dependent variables were added:
35 KEYWORD-html-color
36- Following prometheus.conf variables were removed as obsolete and confusing:
37 htb-ceil-bonus-divide, htb-ceil-divide
39version 0.6 2006-06-29
41- Hyper-optimized iptables hashing (automatic, but compile-time configurable)
42- Option hashtable-treshold was made now obsolete
43- No "Proxy" column in statistics when qos-proxy-enable is set to 0
44- iptables verbose output parsing was rewritten
45- Unfinished implementation of some pps limiting and soft-restart related code
46- Maybe I have changed something else too, but it was long time since last release
48version 0.5.3 2005-08-15
50- Predictable error messages generated by tc and iptables were
51 redirected to /dev/null
52- magic-fixed-prio and magic-relative-prio can be used even with
53 magic-fixed-limit and magic-relative-limit set to 0
54- Minor bugs in data initializtion were fixed, so program should
55 compile and run also on exotic non-X86 plaforms like BusyBox Linux
57version 0.5.2 2005-06-19
59- Fixed long integer traffic counter overflow at 4 gigabytes (up or down)
60- Fixed incorrect inclusion of http proxy traffic in direct traffic
61- Fixed incorrectly displayed parameters of asymetrical upload (Jakub Walczak)
62- Dry run (-d switch) output beautification
63- Added check if minimum data transfer value is greater then 0 kbps
64- magic-priorities added, allows better soft-shaping wihtout reducing HTB ceil
66version 0.5.1 2005-03-22
68- Fixed serious bug in 0.5 release
70version 0.5 2005-03-21
72- Better compatibility with up-to-date gcc and new HTB in 2.6.x kernel
73- Enterprise Research and Planning (ERP) analysis implemented
74- Credit file support implemented (for use with magic-relative-limit)
75- magic-relative-limit-4prio now allows softer FUP using HTB prio
76- digital-divide-weirdness-ratio added, only tested value is "2"
77- qos-leaf-discipline and other new prometheus.conf keywords added
79version 0.4 2004-11-02
81- HTTP proxy traffic accounting bug fixed (occured with hashed iptables)
82- free bandwith traffic shaping (allowed unlimited upload with hashing)
83- maximal guaranted speed increased to 2048 kbps (just tc namespace problem)
84 (Read: it seems that maximum index of tc classes is restricted to 10000)
85- qos-proxy-ip can be inside qos-free-zone even if qos-proxy-enable
86 (Read: Single machine can run NAT/firewall, HTTP proxy and Prometheus QoS)
87- command line argument -n (no delay) overrides qos-free-delay keyword
88 (Read: Separate configuration file for first run and daily run is not needed)
89- traffic from unregistered IPs is monitored even with hashing enabled
91version 0.3 2004-10-13
93- massive performance improvement thanks to hashing of iptables
94- hashtables for /24 subnets are forced if there are 256+ traffic classes
95- hashtables can be forced using new option hashtable-treshold)
96- qos-free-zone is now optional (use qos-free-zone 0)
97- minor bug fix: -h command line arugment now overrides config file
99version 0.2 2004-09-20
101- daily logging of data transfered in individual traffic classes
102- preview feature (create HTML hall of fame without reseting counters)
103- delay feature (useful for creating QoS-free period without reseting counters)
104- <A NAME=""> anchors with hostnames of individual traffic classes
105- tested succesfuly on our upgraded 10Mbps-full duplex, <1000 packets/sec
107version 0.1
109- initial release
110- tested succesfuly on our 3Mbps-full duplex line
