Ogg Vorbis Historic, Evolution of Vorbis Tags

Hi all, first post here, so first congratulations to Hydrogen Webmasters ...
I started using Ogg Vorbis with version 1.0 Final so I don't know anything about earlier versions & I didn't found much informations on Ogg Vorbis History on the net so I made my own one but it's very incomplete, can you all plz fill the holes very carefully, so that this post filled with your answers could become an easy reference on Ogg Vorbis History, & even -maybe- be added to the important topic of the Ogg Vorbis forum if answers are very good, thx.
N°1: Alpha Versions ??? Does it even exist ?
Tag (Vendor String) = Xiphophorus libVorbis I 20000508 = V1.0 Beta 1 & Beta 2 ==> N°2: How good was Vorbis at Start (Compared to Lame MP3) + N°3: Beta 1 to Beta 2 major/minor improvements ?
Tag (Vendor String) = Xiphophorus libVorbis I 20001031 = V1.0 Beta 3 ==> N°4: Beta 2 to Beta 3 major/minor improvements ?
Tag (Vendor String) = Xiphophorus libVorbis I 20010225 = V1.0 Beta 4 ==> N°5: Beta 3 to Beta 4 major/minor improvements ?
Tag (Vendor String) = Xiphophorus libVorbis I 20010615 = V1.0 RC1 ==> N°6: Beta 4 to RC1 major/minor improvements ? (Garf said: RC1 = Beta4 + complete decoder, RC1 = Point of decoder compatibility with future versions but has a little bug so compatility really started with RC2, already better than MP3, Garf joined)
Tag (Vendor String) = Xiphophorus libVorbis I 20010813 = V1.0 RC2 ==> N°7: RC1 to RC2 major/minor improvements ? (Garf said: RC2 = first with channel coupling + bugfix in decoder, sometimes Beta 4 perfoms better than RC2)
Tag (Vendor String) = Xiphophorus libVorbis I 20011231 = V1.0 RC3 ==> N°8: RC2 to RC3 major/minor improvements ?
Tag (Vendor String) = Xiph.Org libVorbis I 20020717 = V1.0 Final ==> N°9: RC3 to V1.0 major/minor improvements ?
(Edit1: V1.00 Final's Lossless Channel Coupling start at Quality 6 with a little jump on average bitrate while in older Vorbis versions it starts at Quality 5 with a noticable jump of 20kbps on average bitrate, & that's the reason why you may find some RC3 Vorbis files encoded at quality 4.99, but encoding at 4.99 (or 5.99) to gain space is now obsolete")
Tag (Vendor String) = Xiphophorus libVorbis I 20011217 = V1.0 RC3 ==> Xiphmont said: "The info version was accidentally not updated in one of the windows builds, so that piece of software had the wrong version for the rc3 version"
Rarewares Compiled Versions:
Tag (Vendor String) = Xiph.Org libVorbis I 20030909 = V1.01 ==> N°10: V1.0 to V1.01 minor bugfixes in the code source, right ?
==> This unofficial Rarewares V1.01 tag may evolve if bugs are found before the official Xiph release of V1.01, right ?
Tag (Vendor String) = Xiph.Org libVorbis I 20030308 = V1.01 ==> Rarewares homemade compil of V1.01 (Read 20030803 ?)
N°11: Anything special to say about Rareware Compiled Versions ?
Garf Tuned Versions:
Tag (Vendor String) = Xiphophorus libVorbis I 20010816 (gtune 1) Based on V1.0 Beta rc2 ==> GT1 Garf Pre-Echo Tuned for 180NKbps & some others unknown fixes, right ?
Tag (Vendor String) = Xiphophorus libVorbis I 20011014 (GTune 2) Based on V1.0 Beta rc2 ==> GT2 Garf Pre-Echo Tuned for 180NKbps & some others unknown fixes, right ?
Tag (Vendor String) = Xiph.Org/Sjeng.Org libVorbis I 20020717 (GTune 3, beta 1) Based on V1.0 Final ==> GT3b1 Garf Pre-Echo Tuned for 180NKbps & up, right ?
Tag (Vendor String) = Garf said: No Tags ! Deleted Just After Its Creation Based on V1.0 Final ==> GT3b2 Garf Pre-Echo Untuned for 180NKbps & up, Experimental Version Deleted Due to Bad Results
N°12: Anything special to say about Garf Tuned Versions ?
Future Versions ? :
V1.1 The Perfect Codec for Video (Theora) (Q2): Low Bitrates AAC Killer, Pre-Echo fixed, When it's Done, 6 months to 1 year, so April 2004 (Optimistic) - October 2004 (Pessimistic), right ?
V1.2 The Perfect Codec for Lossy Audio (Q5-6): High Bitrates MPC Killer, The sooner the better, let's say middle of 2005 (Complete Extrapolation), right ?
N°13: Anything special to say about next Monty Versions ?
Version Time Travel:
Beta 2 to Beta 3: 5.5 Months
Beta 3 to Beta 4: 4 Months
Beta 4 to RC1: 4 Months
RC1 to RC2: 2 Months
RC2 to RC3: 4.5 Months
RC3 to V1.0: 7.5 Months
V1.0 to V1.01: 14 Months
N°14: Personnaly I don't think 14 months is "so" long, considering that if the codec itself didn't evolved much, the support for the codec evolved much during that year which is the same thing for me ...
If you think Ogg Vorbis development is slow, just have a look in Xiph IRC channels & stay there a couple of day ... you'll soon realize how hard the Xiph developing team is working to deliver its best ...
