This version introduces the following changes to make the Wasmer API more ergonomic and safe: 1. `ImportsObject` and the traits `Resolver`, `NamedResolver`, etc have been removed and replaced with a single simple type `Imports`. This reduces the complexity of setting up an `Instance`. The helper macro `imports!` can still be used. -2. The `Engine`s API has been simplified, Instead of the `wasmer` user choosing and setting up an engine explicitly, everything now uses the universal engine. All functionalites of the `staticlib`,`dylib` Engines should be available unless explicitly stated as unsupported. +2. There is a new `Context` that goes along the `Store`. The `Context` will keep track of all memory and functions used, removing old tracking and Weak/Strong pointer difference. Every function and memory that is retreive is linked to a specific `Context`, and cannot be mixed with another `Context` +3. `WasmerEnv` and associated traits and macro have been removed. To use Environenment, a simple structure now need to be attached to the `Context`, and can be retreive from current `Context`. All functions now takes a mendatory first argument that is of type `ContextMut<_>`, with `_` being either nothing `()` or the Environement type needed. the function creation `XXX_with_env(...)` don't exist anymore, simply use `Function::new(...)` or `Function::native_new(...)` with the correct `ContextMut<_>` type. Because the `WasmerEnv` and all helpers don't exists anymore, you have to import memory yourself, there isn't any per instance initialisation automatically done anymore. It's especialy important for WasiEnv context. `Env` can be accessed from a `Context` using `Context::data()` or `Context::data_mut()`. +4. The `Engine`s API has been simplified, Instead of the `wasmer` user choosing and setting up an engine explicitly, everything now uses the universal engine.
