-## [Unreleased]
-
-### Added
-
-#### Object-Oriented Chart Classes
-- **BarChart** - Create horizontal bar charts with type-safe configuration
-- **LineChart** - Create line charts with date/time formatting and multiple series
-- **ColumnChart** - Create vertical column charts with custom ranges and styling
-- **AreaChart** - Create area charts with fills and stacking options
-- **ScatterPlot** - Create scatter plots with size and color encoding
-- **StackedBarChart** - Create stacked bar charts for composition analysis
-- **ArrowChart** - Create arrow charts for showing change over time
-- **MultipleColumnChart** - Create grouped column charts for comparisons
-
-#### Type-Safe Enums
-- **NumberFormat** - 31 semantic number formatting options (e.g., `THOUSANDS_SEPARATOR`, `ABBREVIATED`, `PERCENT_TWO_DECIMALS`)
-- **DateFormat** - 50 date formatting patterns (e.g., `MONTH_ABBREVIATED_WITH_YEAR`, `YEAR_QUARTER`, `DAY_OF_WEEK_FULL`)
-- **NumberDivisor** - 11 number scaling options (e.g., `DIVIDE_BY_MILLION`, `AUTO_DETECT`, `MULTIPLY_BY_HUNDRED`)
-- **LineWidth** - 4 line width options (`THIN`, `MEDIUM`, `THICK`, `EXTRA_THICK`)
-- **LineDash** - 5 line dash patterns (`SOLID`, `DASHED`, `DOTTED`, `DASH_DOT`, `LONG_DASH`)
-
-#### Pydantic Models
-- **ColumnFormat** - Type-safe column formatting with validation
-- **Annotate** - Chart annotation configuration
-- **Describe** - Chart description and metadata
-- **Logo** - Custom logo configuration
-- **Publish** - Publishing settings and options
-- **PublishBlocks** - Control which chart elements to publish
-- **Sharing** - Social sharing configuration
-- **Transform** - Data transformation settings
-- **Visualize** - Visualization-specific settings
-
-#### Annotation Classes
-- **TextAnnotation** - Add text annotations to charts
-- **RangeAnnotation** - Add range annotations to highlight data regions
-- **ConnectorLine** - Add connector lines to annotations
-
-#### Line Configuration
-- **Line** - Configure individual lines in line charts
-- **LineSymbol** - Configure line symbols/markers
-- **LineValueLabel** - Configure value labels on lines
-- **AreaFill** - Configure area fills under lines
-
-#### Serialization Utilities
-- **ColorCategory** - Handle color category mappings
-- **CustomRange** - Handle custom axis ranges
-- **CustomTicks** - Handle custom tick marks
-- **ModelListSerializer** - Serialize lists of Pydantic models
-- **NegativeColor** - Handle negative value coloring
-- **PlotHeight** - Handle plot height configuration
-- **ReplaceFlags** - Handle flag icon replacement
-- **ValueLabels** - Handle value label configuration
-
-### Changed
-
-- **Recommended approach** - Object-oriented chart classes are now the recommended way to create charts
-- **Documentation structure** - Reorganized to prioritize OOP features for newcomers
-- **Code examples** - All examples now showcase type-safe enums and Pydantic models
-- **Package manager** - Updated from pipenv to uv for faster dependency management
-
-### Deprecated
-
-- **Low-level API** - While still fully supported and backwards compatible, the low-level dictionary-based API (`create_chart()` with raw dictionaries, `update_metadata()` with nested dicts) is no longer the recommended approach. It remains available for advanced use cases and edge cases not yet covered by OOP classes.
-
-### Technical Details
-
-- **Pydantic validation** - All chart classes use Pydantic v2 for runtime type checking and validation
-- **Backwards compatibility** - All existing code using the low-level API continues to work without changes
-- **Test coverage** - 754 tests passing (unit, integration, and functional tests)
-- **Type safety** - Full mypy type checking support
-- **Code quality** - Passes ruff linting checks
-
-### Benefits
-
-- 🎯 **Type safety** - Catch configuration errors before runtime with Pydantic validation
-- 💡 **IDE autocomplete** - Discover available options as you type with full IntelliSense support
-- 📖 **Readable code** - Use semantic enum names (e.g., `NumberFormat.THOUSANDS_SEPARATOR`) instead of cryptic format strings (e.g., `"0,0"`)
-- 🔧 **Flexible** - Mix OOP chart classes with low-level API calls when needed
-- 📚 **Self-documenting** - Comprehensive docstrings and type hints make the API discoverable
