1.0
Official Name: Falling Sand Game

The release of the game. It had 80 elements* and many interactions, though the way it was coded was weird. Interactions used <touching colour ?> and only worked if particles were moving unless you turned on “static updates”. It was very unoptimised and lagged when there were more than 10 moving particles, but it worked.

*approximately. Real number was lost.

Changes
Elements

• Eraser tool and wall element were moved to the bottom right for easier access

^^^
1.3
No Official Name

1.3 fixed several behaviour issues.
Changes
Behaviour

• Powders and sturdy powders can fall through liquids and gases
  
• Liquids can fall through gases

Bugfixes

• Fixed an issue which caused major performance problems with static updates: Static interactions will only stamp if it changed types.

1.4
No Official Name

1.4 was a massive update, making particles be able to have textures. This is also when the project was added to the Scratch Design Studio Pixelated, getting the first views on the project.
Additions
Visual

• Textured particles

Changes
Behaviour

• Interactions now check for particle type rather than colour.
  
• Added project to SDS.

1.5
No Official Name

1.5 was released during the golden age (when the project was getting more and more views). It added many key features that made the game more like other falling sand games.
Additions

1.5.2
No Official Name

An actually small update.

This is an update that is not finished yet.

2.0
Official Name: New Beginning

2.0 changes everything about the game. Though I didn’t keep track of all the additions, this update adds hundreds of new elements and new mechanics. This update was split into stages of Project: BID-T-I.

Before Project: BID-T-I
Approximately 100 new elements were added, bringing the total element count to 200+. This made it hard to find an element so the element list was split up into these categories: land, liquids, cave, life, energy, gases, construction, weapons, food, machines and special. Smiley and auto smiley were now selectable in the element list.
BID-T-I Preparation
This happened before Project: BID-T-I to prepare for its additions. The following happened:

• Reorganised the element list categories to now be land, liquids, life, powders, solids, energy, gases, weapons, food, machines, special, states and food states to be more like Sandboxels.
  
• Overhauled the options menu to be cleaner to use. More specific options are put inside of a menu and is organised into 6 categories: world, cursor, saves, interface, info and dev tools.
  
• Changed acid and the old acid is now ‘super acid’, available in the special category.

Stage B
B stands for Binary. This was because before this, to check if a pixel is already active, it used the list contains block, which is obviously slow. Stage B made it so that each pixel has a 1 or a 0, signalling if it was already active.
Stage I (1)
The first I stands for ID. It made particle logic reference off of the particle ID instead of seeing if a particle is within a list. Particles can be edited in game by going to dev tools > element editor. It also changed the save code format. Instead of using x and y positions, it used list indexes and values, like the direction of bouncy particles, was a seperate value instead of a number at the end of the particle name. Density simulation was also added with heavier elements sinking and gases rising if lighter than the air density setting. Liquids also have more realistic viscosity. Stage I (1) did remove interactions, but will be added back and overhauled in stage I (2).
Stage D
D stands for Data. It added 3 data lists which allows pixels to carry information across frames without having to put a number at the end of the name. There was also fall distance for impact related interactions. There was also some preparation for 3.0’s larger canvas sizes.
Stage I (2)
For some reason I decided to make stage I (2) before stage T. In progress.
