Summary & Key Takeaways ​

• Fixed a directory traversal vulnerability in the local development server on Windows.
• Added integrity checks to the Deno API installation script to prevent binary tampering.
• Corrected a minifier bug that incorrectly inlined using and await using declarations, preventing proper resource disposal.
• Addressed an issue where module evaluation state was not preserved after an error.

Our Commentary ​

Security fixes are always welcome, especially when they address potential directory traversal. The using/await using fix is also crucial; it's easy to overlook how minifiers can subtly break new language features. We're glad to see esbuild staying on top of these details.
