Upgrading?

AI Summary

A patch release focusing on build type-checking improvements, header matching fixes, and CSS grid gap adjustments in the Hono framework.

Key Highlights

  • Internal types are now kept private in bundled TypeScript declarations to avoid self-referencing JSX.IntrinsicElements.
  • Mixed-case header names are now correctly matched in the retainedHeader option.
  • Numeric grid properties (`gridGap`, `gridRowGap`, `gridColumnGap`) now correctly add 'px' units.
  • Middleware short-circuiting in the `some()` function now properly returns a Response.

New Features

  • Type-checking of bundled declarations from consumer projects
  • Improved JSX intrinsic elements handling
  • CSS grid gap unit fixes
  • Middleware response handling improvements
