AI Summary

Focuses on minification optimizations and parser enhancements, introducing a breaking change to allocator internals and adding features like dropping false conditions in minifiers and attaching all comments to nodes.

Key Highlights

  • Breaking change: `Allocator::cursor_ptr` and `data_end_ptr` are now private.
  • Minifier optimizations: Dropping false conditions and inverting boolean literals.
  • Parser enhancement: All comments are now attached to nodes.
  • Bug fixes for semantic analysis, regex handling, and JSX diagnostics.

Breaking Changes

  • Make `Allocator::cursor_ptr` and `data_end_ptr` private

New Features

  • Drop cases whose condition is statically false in minifier.
  • Attach all comments to nodes.
  • Invert `!0` and `!1` in place for boolean context to `1` and `0`.
  • Expand fold leading assignments into the var decl.
