+## 🚀 Version 2.0.0.1 (2026-09-15)
+
+**Release tag:** `v2.0.0.1`  
+**Base compatibility line:** `v2.0.x`
+
+### What's New
+* Added a complete release report section for this version, including release scope, tags, and rollout-facing notes.
+* Improved release documentation consistency across changelog, versioning, and installation references.
+
+### What’s Fixed
+* Formatter internals now avoid temporary string allocations in high-frequency formatting paths.
+* Expression and numeric output formatting now write directly to buffers, reducing overhead in formatter execution.
+
+### Full Report
+* **Area:** Tooling performance and release documentation hardening.
+* **Impact:** Faster formatter behavior under repeated formatting operations and clearer release/tag guidance for maintainers.
+* **Upgrade note:** Existing 2.0 scripts remain compatible; this release focuses on fixes and release-quality documentation updates.
