Although the official servers generally followed the same episode progression (like what you linked), things like changing the zeny value of an item are very server specific. They fixed bugs or exploits as needed, so you won't find any detailed guide like:
- 08/04/2005 - Peach Tree monster's Royal Jelly worth more.
The best that you could hope for is to go through all of eAthena and rAthena logs to see what was changed, but it won't give you any date of official servers and it would be a ton of stuff to sift through. If you're looking for more information than what order episodes happened in, you'll have to be a lot more specific in your question. Some stuff can be found in old athena changelogs. Some can be found from web archives.

You can also see on iRO when they did things like adding monster cards by looking at super old updates.New monster cards on 09/22/2005 (http://www.playragnarok.com/news/updates.aspx?page=10)
Anyways, I don't think the detailed guide you're requesting exists. You'll just have to be more concise in your googling or asking on the forums with what you're looking for.
