CHANGELOG.md

Next Release

Enso IDE

• Fix AI prompt cancellation leaving the queue wedged. Cancelling an in-flight prompt could leave the next prompt failing with stdin write failed, and any subsequent prompt stuck on "waiting"; the cancel path now pre-swaps the child's readiness deferred so follow-up prompts synchronize on the respawned claude child instead of racing past a stale ready and writing into a dying stdin.
• AI mode in the Component Browser is now a first-class option, with a three-way mode switch (robot / search / code) accessible by clicking the icon next to the Component Browser input. The mode defaults to AI when the local claude CLI is found, and to component search otherwise. Existing AI nodes can be edited by reopening the Component Browser on them — the prior prompt is sent back to the agent so the function definition is rewritten in place.

Anonymous Data Collection

Please note that this release collects anonymous usage data which will be used to improve Enso and prepare it for a stable release. We will switch to opt-in data collection in stable version releases. The usage data will not contain your code (expressions above nodes), however, reported errors may contain brief snippets of out of context code that specifically leads to the error, like "the method 'foo' does not exist on Number". The following data will be collected:

• Session length.
• Project management events (project open, close, rename).
• Errors (IDE crashes, Project Manager errors, Language Server errors, Compiler errors).
