Today we're no longer deploying 1.0.0-rcX versions or versions from the [stable branch](https://github.com/extism/extism/tree/stable). We're officially cutting 1.0.0 across all repos. This has been a massive undertaking and we have a few highlights we'd like to call out from the community:
Community Highlights
- Philippe Charrière k33g has been instrumental in getting eyeballs on Extism. There is really too much to highlight. But here are a few things:
+ [Simplism](https://github.com/bots-garden/simplism) is a really awesome FAAS wrapper around Extism. It's really incredible to see Extism turned into a full on FAAS!
+ Phillipe also did [some presentations](https://www.youtube.com/watch?v=5HBglrvHtWg) where he talked about Extism
- Doğu Us usdogu is pretty much single-handedly handling our Zig support!
* He created the [Zig SDK](https://github.com/extism/zig-sdk)
* He created the [Zig PDK](https://github.com/extism/zig-pdk)
* He's also been super responsive to issues and updates
- Chance Snow chances created a new [D SDK](https://github.com/extism/d-sdk)!
- Thomas Darimont thomasdarimont is the primary driver of the [Java SDK](https://github.com/extism/java-sdk) and has been crucial to
helping us break into the Java ecosystem
- Etienne Anne Zwiterrion from [Otoroshi](https://maif.github.io/otoroshi/) was also crucial on our Java SDK and has done some interesting work to get [OPA](https://www.openpolicyagent.org/) to work in Extism.
- Egon Elbre egonelbre has made some great improvements to the Go PDK including [removing the C dependency](https://github.com/extism/go-pdk/pull/15)
- Quinn Millican syke99 has also made improvements to the Go PDK as well as providing lots feedback and ideas on our Go ecosystem
- Luke Paireepinart lukevp has made a ton of contributions to our Dotnet and our JS ecosystem.
Migration Notes
Here are some notes about breaking changes if you're trying to migrate from 0.5.x:
Overview
- There is a new Extism CLI rewritten in Go: https://github.com/extism/cli
- The Rust SDK and C SDK are still in `extism/extism`
- The other SDKs have been moved from `extism/extism` to their own repos (for example, `extism/python-sdk`)
- The Go SDK uses Wazero and the JS SDK uses the native WASM engine for the JS runtime being used (node, deno, bun, browser)
- The `Context` type has been removed and plugin creation no longer takes a context argument in any SDK.
- The module namespace for Extism host function has been changed to `extism:host/env` and user-defined host functions are now in `extism:host/user` by default.
Runtime/Rust SDK
- `extism-runtime` and `extism` crates have been combined. Only `extism` should be used now.
- `Plugin::new_with_manifest` has been removed - manifests can be passed to `Plugin::new` directly
- `PluginBuilder::new_with_module` has been removed, raw wasm can be passed to `PluginBuilder::new` directly
- `Function::new` now requires a user-data argument when before it was an `Option` parameter, `UserData::default()` can be used instead.
- The `nn` feature has been removed, please reach out if this is an issue for you!
- extism-convert is used to convert Rust types in and out of Extism memory
- `Plugin::call` and other places where data is copied into Extism memory, accept any type that implements `extism_convert::ToBytes` and returns any type that implements `extism_convert::FromBytes`
- Maximum memory is no longer statically checked, an error will be raised when the allocated memory exceeds the configured limit
C SDK
- `ExtismContext` has been removed and `ExtismPlugin` is now a direct pointer to the `extism::Plugin` type
- `extism_plugin_new` takes an additional out-argument to get the error message. Use `extism_plugin_new_error_free` to free error messages.
