10+ ### 🎉 Initial Release
11+
12+ #### Core Parsing & Generation
13+ - ** Complete Lua parser** with full AST generation supporting all Lua 5.1+ syntax
14+ - ** Advanced Luau parser** with type annotations, generics, and modern syntax features
15+ - ** TypeScript code generation** from Luau type definitions with intelligent mapping
16+ - ** Lua code formatting** with customizable styling options and pretty-printing
17+ - ** AST manipulation utilities** with comprehensive type definitions
18+
19+ #### Advanced Type System
20+ - ** Primitive type mapping** : ` string ` , ` number ` , ` boolean ` , ` nil ` → ` null `
21+ - ** Optional types** : ` foo: string? ` → ` foo?: string `
22+ - ** Array types** : ` {string} ` → ` string[] ` with proper element type detection
23+ - ** Record types** : ` {[string]: any} ` → ` Record<string, any> ` and index signatures
24+ - ** Union types** : ` "GET" | "POST" | "PUT" ` with string literal preservation
25+ - ** Intersection types** : ` A & B ` with proper parenthesization
26+ - ** Function types** : ` (x: number) -> string ` → ` (x: number) => string `
27+ - ** Method types** : Automatic ` self ` parameter removal for class methods
28+ - ** Generic types** : Support for parameterized types and type variables
29+ - ** Table types** : Complex nested object structures with property signatures
30+
31+ #### Language Features
32+ - ** Template string interpolation** : Full backtick string support with ` ${var} ` and ` {var} ` syntax
33+ - ** Continue statements** : Proper parsing with loop context validation
34+ - ** Reserved keywords as properties** : Handle ` type ` , ` export ` , ` function ` , ` local ` as object keys
35+ - ** Comment preservation** : Single-line (` -- ` ) and multi-line (` --[[ ]] ` ) comment handling
36+ - ** JSDoc conversion** : Transform Lua comments to TypeScript JSDoc format
37+ - ** Export statements** : Support for ` export type ` declarations
38+ - ** String literals** : Proper handling of quoted strings in union types
39+
40+ #### Modular Architecture
41+ - ** Component-based lexer** : Specialized tokenizers for numbers, strings, identifiers, comments
42+ - ** Pluggable tokenizer system** : Easy extension with new language constructs
43+ - ** Operator precedence handling** : Correct parsing of complex expressions
44+ - ** Error recovery** : Graceful handling of syntax errors with detailed diagnostics
45+ - ** Memory efficient** : Streaming parsing for large files
46+
47+ #### Plugin System
48+ - ** File-based plugins** : Load plugins from JavaScript/TypeScript files
49+ - ** Inline plugin objects** : Direct plugin integration in code
50+ - ** Type transformation hooks** : Customize how Luau types map to TypeScript
51+ - ** Interface modification** : Add, remove, or modify generated interface properties
52+ - ** Post-processing** : Transform final generated TypeScript code
53+ - ** Plugin registry** : Manage multiple plugins with validation
54+ - ** Hot reloading** : Plugin cache management for development
55+
56+ #### CLI Tools
57+ - ** File conversion** : ` luats convert file.lua -o file.d.ts `
58+ - ** Directory processing** : ` luats convert-dir src/lua -o src/types `
59+ - ** Watch mode** : Auto-regeneration on file changes with ` --watch `
60+ - ** Syntax validation** : ` luats validate ` for error checking
61+ - ** Configuration files** : Support for ` luats.config.json ` with rich options
62+ - ** Glob patterns** : Include/exclude file patterns for batch processing
63+
64+ #### Developer Experience
65+ - ** Comprehensive TypeScript definitions** : Full type safety for all APIs
66+ - ** Error handling** : Detailed error messages with line/column information
67+ - ** Snapshot testing** : Fixture-based testing for regression prevention
68+ - ** Performance optimizations** : Efficient parsing and generation algorithms
69+ - ** Documentation generation** : Generate docs from parsed code structures
70+
71+ #### Configuration Options
72+ - ** Type generation** : ` useUnknown ` , ` interfacePrefix ` , ` includeSemicolons `
73+ - ** Comment handling** : ` preserveComments ` , ` commentStyle ` (jsdoc/inline)
74+ - ** Code formatting** : Indentation, spacing, and style preferences
75+ - ** Plugin configuration** : File paths and plugin-specific options
76+ - ** Include/exclude patterns** : Fine-grained control over processed files
77+
78+ #### Testing & Quality
79+ - ** 47 comprehensive tests** covering all major functionality
80+ - ** 100% test pass rate** with robust edge case handling
81+ - ** Snapshot testing** for generated TypeScript output validation
82+ - ** Plugin system testing** with both file and object-based plugins
83+ - ** CLI integration tests** with temporary file handling
84+ - ** Error scenario testing** for graceful failure handling
85+
86+ #### Examples & Documentation
87+ - ** Plugin examples** : ReadonlyPlugin, CustomNumberPlugin, TypeMapperPlugin
88+ - ** CLI usage examples** : Common workflows and configuration patterns
89+ - ** API examples** : Programmatic usage for all major features
90+ - ** Roblox integration** : Specific examples for game development workflows
91+
92+ ### Technical Details
93+ - ** Lexer** : 4 specialized tokenizers (Number, String, Identifier, Comment)
94+ - ** Parser** : Recursive descent with operator precedence and error recovery
95+ - ** Type System** : 15+ AST node types with full TypeScript definitions
96+ - ** Plugin Architecture** : 4 transformation hooks (transformType, transformInterface, process, postProcess)
97+ - ** CLI** : 4 main commands with configuration file support
98+ - ** Exports** : Modular imports for tree-shaking and selective usage
99+
100+ This release establishes LuaTS as a production-ready tool for Lua/Luau to TypeScript workflows, with particular strength in Roblox development, legacy code integration, and type-safe API definitions.
