Kora 0.3.1

Published 16 September 2026. View the release history and downloads .

0.3.1 is a packaging fix. The language, runtime, and editor support are unchanged from 0.3.0.

Changes

• kora-helper is published to crates.io before the crates that depend on it.

Why this release exists

kora-helper is a workspace member and a dependency of kora-runtime, but it was never listed in the crates.io publish step, so it had never been published. Nothing revealed that until 0.3.0: the crate arrived with the confined package helpers, after kora-runtime had already published at 0.2.0.

cargo publish -p kora-runtime stops at “no matching package named kora-helper found” before it uploads anything, and the publish script stops with it. 0.3.0 therefore reached crates.io as six crates rather than ten.

kora-runtime, kora-lsp, and kora-dap have no 0.3.0 on crates.io. They resume at 0.3.1. Every other distribution channel published 0.3.0 normally, so this affects only projects that depend on those three crates directly from crates.io. Depend on 0.3.1 or later.

Breaking changes

None.

Migration from 0.3.0

None needed. If a Cargo.toml pins kora-runtime, kora-lsp, or kora-dap at 0.3.0, move it to 0.3.1, since that version was never published:

cargo update -p kora-runtime
kora --version

Installing from Homebrew, the VS Code Marketplace, or a release archive needs nothing beyond the normal upgrade.

Compatibility

Kora remains pre-alpha. There is no stable language or package compatibility promise yet.
