Release Notes

Microsoft/vscode-extension-telemetry (@​vscode/extension-telemetry)

v0.9.1: Fix unhandlederror common props.

Compare Source

Thanks to a community contribution by @​ilia-db the unhandlederror event handler has been properly fixed to include common properties.

v0.9.0: Use app insights basics versus the complete app insights package to reduce bundle size

Compare Source

Application insights web basics comes with the ability to pass in a fetch pollyfill that allows it to be used for both Node and Web. This is similar to what we already do for first party extensions using the 1DS package.

While there is no breaking changes here, the replacement of a key dependency with what should be an equivalent alternative may have unknown edge cases that were not accounted for, therefore the version has been bumped to reflect this.

Bundlephobia reports a 67Kb decline in bundle size with this change.
