What's Changed

Added

• [#1033] Keep cabi realloc by @dantinkakkar in #1035
• The Javy CLI now supports plugins compiled to target WASI preview 1 alongside our existing support for WASI preview 2. Consult our documentation on extending Javy for how to write a plugin that targets WASI preview 1. This should restore any broken behaviour for using stdio for input and output when compiling a plugin with Rust 1.91.0 or later.

Changed

• RQuickJS has been updated. The QuickJS bytecode emitted by the default plugin is no longer compatible so the import namespace of the default plugin has been changed.

Removed

• The Javy CLI no longer supports WIT worlds using older WIT syntax without trailing semicolons.

New Contributors

Full Changelog: v5.0.2...v5.0.3

Full Changelog: v4.0.0...v5.0.0

What's Changed

This release involves two breaking changes to the CLI.

1. javy emit-provider has been renamed to javy emit-plugin.
2. javy build -C dynamic now requires a -C plugin=... argument as well. javy emit-plugin can be used to obtain a default plugin that can be used for building dynamically linked modules.

Also, the javy-plugin-api crate has been published to crates.io so it can be used to author your own Javy plugins!

• Switch plugin to build on Linux by @jeffcharles in #830
• Rename emit-provider subcommand to emit-plugin by @jeffcharles in #819
• Add support for plugins to dynamically linked modules by @jeffcharles in #821
• Update docs for plugins by @jeffcharles in #832
