What's Changed

The big change with v6.0.0 is the plugin API expected by the Javy CLI has changed in a breaking way. Please consult the extending Javy documentation for the new plugin API and the README in the javy-plugin-api crate for steps to migrate your plugin.

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

What's Changed

• javy init-plugin now supports plugins that use LEB128 variable-length integer encoding for zero index values in their Wasm. This means initializing plugins compiled with Rust 1.85 should no longer return error messages about index values.

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
