The minimum required TypeScript version is increased to version `TODO`. We also no longer emit down-leveled types.

Esbuild override removed accidentally

Medium Severity

Cleaning up the TS 3.8 sentryTest variants also dropped the unrelated pnpm.overrides pin for esbuild at 0.24.0. That pin is a bundler constraint, not TypeScript downlevel support, and similar apps such as astro-5 still keep it. Losing it can make these Vite E2E installs resolve a different esbuild and break test:build.

Esbuild override removed accidentally
Medium Severity
Cleaning up the TS 3.8 sentryTest variants also dropped the unrelated pnpm.overrides pin for esbuild at 0.24.0. That pin is a bundler constraint, not TypeScript downlevel support, and similar apps such as astro-5 still keep it. Losing it can make these Vite E2E installs resolve a different esbuild and break test:build.

### TypeScript Version Policy

<!-- TODO(v11): Fill in the final minimum TypeScript version once decided. -->

The minimum required TypeScript version is increased to version `TODO`. We also no longer emit down-leveled types.
The minimum required TypeScript version is increased to version `5.0.4`. We also no longer emit down-leveled types.

Older TypeScript versions _may_ continue to be compatible, but no guarantees apply.

The minimum required TypeScript version is increased to version `TODO`. We also no longer emit down-leveled types.

Esbuild override removed accidentally
Medium Severity
Cleaning up the TS 3.8 sentryTest variants also dropped the unrelated pnpm.overrides pin for esbuild at 0.24.0. That pin is a bundler constraint, not TypeScript downlevel support, and similar apps such as astro-5 still keep it. Losing it can make these Vite E2E installs resolve a different esbuild and break test:build.

Esbuild override removed accidentally
Medium Severity
Cleaning up the TS 3.8 sentryTest variants also dropped the unrelated pnpm.overrides pin for esbuild at 0.24.0. That pin is a bundler constraint, not TypeScript downlevel support, and similar apps such as astro-5 still keep it. Losing it can make these Vite E2E installs resolve a different esbuild and break test:build.

<!-- TODO(v11): Fill in the final minimum TypeScript version once decided. -->

The minimum required TypeScript version is increased to version `TODO`. We also no longer emit down-leveled types.
The minimum required TypeScript version is increased to version `5.0.4`. We also no longer emit down-leveled types.

Older TypeScript versions _may_ continue to be compatible, but no guarantees apply.

Esbuild override removed accidentally
Medium Severity
Cleaning up the TS 3.8 sentryTest variants also dropped the unrelated pnpm.overrides pin for esbuild at 0.24.0. That pin is a bundler constraint, not TypeScript downlevel support, and similar apps such as astro-5 still keep it. Losing it can make these Vite E2E installs resolve a different esbuild and break test:build.

Esbuild override removed accidentally
Medium Severity
Cleaning up the TS 3.8 sentryTest variants also dropped the unrelated pnpm.overrides pin for esbuild at 0.24.0. That pin is a bundler constraint, not TypeScript downlevel support, and similar apps such as astro-5 still keep it. Losing it can make these Vite E2E installs resolve a different esbuild and break test:build.
