 ## [Unreleased]
 
+### Added
+- **Repo Update** (2025-10-12 – jarroddavis68)
+  Release v0.2.0: Core language features and RTL foundation
+  This release establishes the foundational architecture and implements core
+  Object Pascal language features with the RTL wrapping strategy.
+  LANGUAGE FEATURES:
+  - Complete basic type system (Integer, Double, String, Boolean, Pointer, etc.)
+  - Type aliases and pointer type declarations
+  - Constants (typed and untyped) and variables (local/global)
+  - All arithmetic, comparison, logical, and bitwise operators
+  - Control flow: if/else, case, for, while, repeat-until
+  - Functions and procedures with multiple parameter passing modes
+  - Static arrays, records, enumerations, and pointers
+  - Memory management (New/Dispose)
+  RUNTIME LIBRARY (RTL):
+  - I/O functions (Write/WriteLn with variadic templates)
+  - Control flow wrappers (ForLoop, WhileLoop, RepeatUntil)
+  - Operator functions (Div, Mod, Shl, Shr)
+  - String class (np::String with UTF-16 and 1-based indexing)
+  - All Delphi semantics wrapped in np:: namespace
+  CODE GENERATION:
+  - Header (.h) and implementation (.cpp) file generation
+  - Namespace per unit
+  - RTL wrapping strategy: complexity in RTL, not codegen
+  - Forward declarations and proper includes
+  BUILD SYSTEM:
+  - Zig build integration for cross-platform compilation
+  - Multiple optimization modes (Debug, ReleaseSafe, ReleaseFast, ReleaseSmall)
+  - Program → executable, Library → .dll/.so/.dylib, Unit → .lib/.a
+  - Compiler directives support ({$optimization}, {$target}, etc.)
+  TOOLS:
+  - nitro CLI with build, run, clean, init, version, help commands
+  PLATFORMS:
+  - Windows x64, Linux x64, macOS x64
+  DOCUMENTATION:
+  - Updated README.md with documentation links (COVERAGE.md, DESIGN.md, MANUAL.md)
+  - Updated code examples to demonstrate RTL wrapping approach
+  - Added DelphiAST attribution
+  - Complete language coverage tracking (COVERAGE.md)
+  - Comprehensive design document (DESIGN.md)
+  ARCHITECTURE:
+  The core architectural principle is RTL wrapping: all Delphi constructs are
+  wrapped in C++ runtime library functions. This makes the code generator a
+  simple syntax translator while ensuring correct Delphi semantics. The
+  transpilation pipeline is: Pascal → C++ (via RTL) → Native Code (via Zig/LLVM).
+  Version: 0.2.0
