on GitHub

What's Changed

🐞 Fixes

• react-x/no-duplicate-key: in .map() callbacks, all statically known keys are now treated as repeating, not only bare string literal attributes: expression-container literals (key={1}, key={"a"}), static template literals (key={`a`}), TS-wrapped literals (key={"a" as const}), and bare key attributes (key={true}) are reported, while key={null} and key={undefined} remain unreported since React falls back to index keys for them.
• react-jsx/no-leaked-semicolon: same-line leaked semicolons after an expression container are now detected (ex: <div>{x};</div>, <div>{cond && <span />};</div>).

🏗️ Internal

• Removed the Vercel deploy step from the release workflow.
