I am 99.99% positive 1.01 was day 1 patch, or realistically ready pre-release but discs had to be pressed in advance and whatnot since 1.00 was impossible to play on bnet to begin with, D2 has release date of June 29 or 30th 2000 depending on region, while 1.02 probably came out early July, since going through some extracted old files it claims date modified 7.7.2000. This would make it pretty educated guess that 1.01 = day 1 patch, 1.02 = one week+ after release.
Regarding builds, having played 1.00 bowazon (1pt jab ofc for jabbing with any kind of spear on some occasions) for giggles and change of pace fairly recent at simulated players 3 (aka two mules idling in game), it basically is just maxing out strafe, herding enemies, having valkyrie and decoy to keep targets still and then unleash strafe preferably at angle you can make most of pierce. On top of that guided arrows to check targets or against individual targets, magic arrow can be useful against single high hp targets so you don't have to use two stacks of arrows. As obligatory reminder, spacing or positioning matters because if you thought strafelock in modern D2 is bad, try D2C strafelock. Also strafe is very wonky against single targets unless it's large, so essentially you are wasting loads of mana for a single arrow that does slightly more damage, hence why guided or even magic arrow is your go-to source, latter so you do not have to go pick more arrows every half a minute while slowly whittling away a boss or so. Depends really on the situation.
I believe skill allocation has been few in obligatory DAE, maxed strafe, probably ~5ish points in critical strike, then some in pierce and few in penetrate. Most of your long-term damage comes out of dexterity while the best bows functionally are ones with just +max damage and as high IAS as possible. Even say, exceptional hunter's bow (forgot the name lol) with IAS and +15 max damage might be better than gothic bow with just max damage, as whenever not using strafe the faster you recover from shots means the sooner you can run away from that extra fast MSLE that appeared out of nowhere.
I will say it has been quite fun challenge overall, and it tends to get easier as you level up due dexterity and odds of having a bow with +max damage.
