Changelog

The fastest way to see what changed in Elide. Highlights come first; detailed version notes follow for each public release line.

Latest published release: 1.3.6+20260705. For install and upgrade commands, see Releases.

Highlights

• JS Node.js compatibility is moving quickly. Recent work adds node:fs, node:crypto, node:path, node:assert, node:util, node:test, streams, process behavior, module shims, and worker-thread plumbing.
• Python Python support is more practical. Elide now tracks Python 3.12-era behavior, fixes stdlib discovery from the shipped Python home, improves cold-start setup, and adds an elide python command.
• JVM JVM and Bazel workflows are sharper. Kotlin and Java compiler work adds elide jdeps, Bazel-aware diagnostics, Kotlin ABI improvements, digest-driven incremental compilation, used-dependency reporting fixes, and faster warm javac workers.
• Install Installation is more complete. The installer path now covers unified NPM/PyPI/JVM dependency installation, local JAR dependencies, Windows installer repair, full-archive upgrades, and smaller NPM platform packages.
• CLI Runtime diagnostics are easier to act on. Guest module-resolution errors, Kotlin diagnostic floods, upgrade output, elide info, and version/channel reporting all received user-facing improvements.

About This Page

This page is curated from recent merged changes, plus public release tags on elide-dev/elide. Dependency-only, CI-only, and test-only changes are omitted unless they affect installation, security, packaging, or runtime behavior. Version grouping uses release milestones where they are set and the public nightly release line otherwise.

Next: 1.4.0

The next 1.4.0 line updates the runtime base and lands a large JavaScript and Python compatibility batch.

1.0.x - 1.2.x Pre-Releases

Elide 1.0.x through 1.2.x were early prerelease lines. They are archived for reference and should not be used for new projects.

Elide Classic

Elide Classic is the pre-1.0 code line preserved in elide-dev/elide on the v5 branch. Classic releases used beta and release-candidate style versions, such as 1.0.0-beta11-rc6, and are useful mainly for understanding older projects that pinned themselves to that era of Elide. The last Classic release was 1.0.0-beta11-rc6; the last public non-RC release is 1.0.0-beta10.

Modern Elide is the current runtime and toolchain line documented above. It uses the newer packaging, installer, JVM toolchain, JavaScript/TypeScript, Python, and native-image architecture represented by the 1.3.x and 1.4.x releases. Classic should be treated as historical unless you are maintaining an existing project on that branch.
