# Framework Diff Log

Desktop .swf/.exe vs .io

### :bulb: Major differences between the old desktop and the new .io version

1. **No more Connection length as time variable**: Resources travel and arrive during the same Time Step, regardless of Connection length. E.g.: if previously the speed of the Resources would stay fixed and the arrival time would vary, now the speed varies and the transfer time is fixed (all Resources arrive to their destination in exactly 1 Time Step). 
2. **No Async Mode**
3. **No Turn Based Mode**
4. **No Artificial Player (AP)** - you can [emulate AP functions](/docs/artificial-player.md) with existing components
5. [**Registers**](https://docs.machinations.io/nodes/registers) **now support the entire** :link: [**math.js**](https://mathjs.org/docs/reference/functions.html) **functions library**. 
6. [**Combining flow rates**](https://docs.machinations.io/labels#combining-random-flow-rates): use `50%+50%` instead of the old `2*50%` label.
7. **Number interval** [**Label**](https://docs.machinations.io/labels) `x-y` has become `x..y` 
8. **Time interval** [**Label**](https://docs.machinations.io/labels)  `x/y` has become `x|y` 
9. [**Charts**](https://docs.machinations.io/charts) **plot the Pool colour,** instead of the Resource's colour.
10. [**Colour Coding**](https://docs.machinations.io/colour-coded-diagrams) **is a Connection-level setting**, it no longer affects the global Diagram.
11. **No more `m` modifier**
12. **Obvious**: Cloud save, UI/UX improvements, Groups, Library, Errors/Validators, Real-time collaboration, Version History
13. [**Triggers**](/docs/connections/state-connections/triggers.md) **cannot trigger** [**Resource Connections**](/docs/connections/resource-connections.md)
