+# Prettier 3.6.2
+
+This update brings Prettier from 3.5.x to 3.6.2. The experimental CLI is particularly noteworthy for teams working with large codebases.
+
+## Major Features from 3.6.0
+
+### Experimental Fast CLI
+
+Prettier 3.6 introduces an experimental high-performance CLI that can be enabled with the `--experimental-cli` flag or `PRETTIER_EXPERIMENTAL_CLI=1` environment variable. This provides significant performance improvements for large codebases.
+
+### New Official Plugins
+
+- **@prettier/plugin-oxc**: Based on OXC (fast JavaScript/TypeScript parser in Rust), providing `oxc` and `oxc-ts` parsers
+- **@prettier/plugin-hermes**: Based on Hermes JS Engine, providing a new `hermes` parser for Flow syntax (planned to replace `babel-flow` in v4)
+
+### JavaScript Formatting Improvements
+
+- **SequenceExpression Parentheses**: Added parentheses to `SequenceExpression` in `ReturnStatement` and `ExpressionStatement` for better code clarity
+- **AssignmentExpression Consistency**: Added parentheses to `AssignmentExpression` in class property keys for consistency with object keys
+
+### TypeScript Formatting Improvements
+
+- **Consistent Number Parentheses**: Added parentheses to numbers in optional member expressions (e.g., `(1)?.toString()`) for consistency across all parsers and to prevent syntax errors when removing optional chaining
+- **Parser Consistency**: Resolved inconsistencies between Babel and TypeScript parsers for better cross-parser compatibility
+
+## Bug Fixes
+
+- **3.6.1**: Fixed "Warning: File descriptor 39 closed but not opened in unmanaged mode" error when running `--experimental-cli`
+- **3.6.2**: Added missing blank line around code blocks for better formatting output readability
