2.4 compatibility in Nexa 3.0

This page describes the retained 2.4 language/runtime path. Sources without a version declaration use this path. Start new Open Programs with Nexa 3.0; compare contracts in the migration guide.

Historical notes

This legacy URL remains as an entry to historical notes. Language, architecture, and tooling material is organized into source-checked topics:

• Unified compiler
• Architecture evolution and experiments
• 2.4 migration checklist

The main repository records individual historical drafts in examples/manifest.json. This site's inventory independently validates its documentation examples.
