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:\r\n\r\n- Session length.\r\n- Graph editing events (node creation, deletion, position change, connect, disconnect, collapse, edit start, edit end). This will not include any information about node expressions used.\r\n- Navigation events (camera movement, scope change).\r\n- Visualization events (visualization open, close, switch). This will not include any information about the displayed data nor the rendered visualization itself.\r\n- Project management events (project open, close, rename).\r\n- Errors (IDE crashes, WASM panics, Project Manager errors, Language Server errors, Compiler errors).\r\n- Performance statistics (minimum, maximum, average GUI refresh rate).\r\n\r\n# Changelog\r\n\r\n#### Enso Language &amp; Runtime\r\n\r\n- [Enforce conversion method return type][10468]\r\n- [Renaming launcher executable to ensoup][10535]\r\n- [Space-precedence does not apply to value-level operators][10597]\r\n\r\n[10468]: https://github.com/enso-org/enso/pull/10468\r\n[10535]: https://github.com/enso-org/enso/pull/10535\r\n[10597]: https://github.com/enso-org/enso/pull/10597\r\n\r\n#### Enso IDE\r\n\r\n- [&quot;Add node&quot; button is not obscured by output port][10433]\r\n- [Numeric Widget does not accept non-numeric input][10457].
