The most significant change, I think, is with the content of the walkthrough itself. There were a lot of errors, big and small, with my interpretation of the story back then (I've decided to summarize them below, for those of you who've used this walkthrough in the past).

There are also five gameplay sections. The Menus page explains the layout of the various menus and basic commands. The Academy page has a map of the two main towns in the game. The Characters page describes all the major and minor characters in the game. The Magic Spells page lists the magic spells and effects for each of the main characters, and the Items page lists the usable items you can obtain or purchase in the game.

Plot Details (Major):

• The character D (top image on right) is really the corporeal form of the Dark Castle (referred to as the Dark Castle D) which Barua and Memphis control. Before, I referred to it as a "Demoness". That was an error.
• There is no Star Dragon. It's really the Blue Dragon (second image on right). What's more, he gives the Blue Dragon Ring to Wing, as proof of his being a Guardian of Time.
• Steel and Glen are known as the Guardians of Time, with respective duties to protect the stream of time. Wing has the same latent abilities that they do, and they take him on to become the next Guardian of Time.
• Moreover, the island of Ien is in the middle of where the stream of time flows through and coils up. Hence the importance of the Guardian of Time and the Blue Dragon's visits about once per decade.
• Ralph, the librarian, says that the goddess generally is reborn as a human once every 500 years (third image on right); the last time was 200 years ago. Since the game occurs before Vane falls from the sky, and after the Vile Tribe was sealed in the Frontier (500 years prior to Dyne's adventures), then this places the events of Lunar: Walking School at about 300 years prior to Lunar: The Silver Star.
• Wing is quite in love with Lena; that much was reflected in the older version. But, he has a problem with being too passive--a trait which Lena hates. Throughout the story, he gradually gains more and more self-confidence, before confessing his love to Lena at the end. By then, Lena has taken a liking to him, too.

Plot Details (Minor):

• Wing isn't on a scholarship at the beginning. All three of the students earn a sholarship after the events in Chapter 8.
• In Chapter 2, during the entrance exam, the students were on a mock-up of the island of Ien while the professors examined their progress (second floor of the office building, eastern room). The test ended prematurely when their secret was discovered by Ant and the others.
• In Chapter 10, rumors start up about Ellie being the human incarnation of the Goddess Althena when Henner's statue of Ellie (in the style of Althena) was presented (first image on right).
• (Other minor storyline corrections have been made throughout. Where things were removed from the previous version of the walkthrough, they were typically either unimportant or factually inaccurate.)

Name Changes:

• The school counselor (first image on right): her name is Emma. I called her Brance before; I have no idea where I got that.
• Aruba's name changed to Alba. Alba is the owner of the item shop.
• Reheater's name changed to Richter. Richter is the architect behind the dormitory bulding.
• Several magic spell and item names were changed to be more accurate.

Character Details:

• Ant and Layla eventually warm up to the students, although Ant still has his irritating moments.
• Wing says that he's from Caldor Island, which is where Burg and Saith are located (first image on right).

Gameplay Details:

• Gaining spells depends entirely on your level when you talk to a given professor; the walkthrough has been updated to reflect that. Forthcoming may be a chart detailing which spells you gain from which professors, and the level at which you can learn them.
