Additionally a + store may not consume its last unit of fuel. + [#5013](https://github.com/bytecodealliance/wasmtime/pull/5013) + +* A number of variants in the `wasi_common::ErrorKind` enum have been removed. + [#5015](https://github.com/bytecodealliance/wasmtime/pull/5015) + +* Methods on `WasiDir` now error-by-default instead of requiring a definition by + default. + [#5019](https://github.com/bytecodealliance/wasmtime/pull/5019) + +* Bindings generated by the `wiggle` crate now always depend on the `wasmtime` + crate meaning crates like `wasi-common` no longer compile for platforms such + as `wasm32-unknown-emscripten`. + [#5137](https://github.com/bytecodealliance/wasmtime/pull/5137) + +* Error handling in the `wasmtime` crate's API has been changed to primarily + work with `anyhow::Error` for custom errors. The `Trap` type has been replaced + with a simple `enum Trap { ... }` and backtrace information is now stored as a + `WasmBacktrace` type inserted as context into an `anyhow::Error`. + Host-functions are expected to return `anyhow::Result` instead of the prior + `Trap` error return from before. Additionally the old `Trap::i32_exit` + constructor is now a concrete `wasi_commont::I32Exit` type which can be tested + for with a `downcast_ref` on the error returned from Wasmtime. + [#5149](https://github.com/bytecodealliance/wasmtime/pull/5149) + +* Configuration of the pooling allocator is now done through a builder-style + `PoolingAllocationConfig` API instead of the prior enum-variant API. + [#5205](https://github.com/bytecodealliance/wasmtime/pull/5205) + +### Fixed + +* The instruction cache is now properly flushed for AArch64 on Windows. + [#4997](https://github.com/bytecodealliance/wasmtime/pull/4997) + +* Backtrace capturing with many sequences of wasm->host calls on the stack no + longer exhibit quadratic capturing behavior. + [#5049](https://github.com/bytecodealliance/wasmtime/pull/5049) + -------------------------------------------------------------------------------- ## 2.0.1
