v1.0.0

Today we're no longer deploying 1.0.0-rcX versions or versions from the stable branch. 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 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 where he talked about Extism
• Doğu Us @usdogu is pretty much single-handedly handling our Zig support!
  • He created the Zig SDK
  • He created the Zig PDK
  • He's also been super responsive to issues and updates
• Chance Snow @chances created a new D SDK!
• Thomas Darimont @thomasdarimont is the primary driver of the Java SDK and has been crucial to
  helping us break into the Java ecosystem
• Etienne Anne @Zwiterrion from Otoroshi was also crucial on our Java SDK and has done some interesting work to get OPA to work in Extism.
• Egon Elbre @egonelbre has made some great improvements to the Go PDK including removing the C dependency
• 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.
