+# Changelog
+
+All notable changes to DataMapper ORM will be documented in this file.
+

+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Added
+- Laravel-style mass-assignment protection: `$fillable`, `$guarded`, `fill()`, `forceFill()`, `unguard()` helpers, and a static `create()` convenience method.
+
+### Documentation
+- Documented mass-assignment workflow, updated the quick reference, model template, and added a dedicated guide page.
+
+## [2.0.0-beta1] - 2025-10-14
+
+### Highlights
+- First public beta of the DataMapper 2.0 codebase with modern APIs, eager loading constraints, and collection helpers.
+- New compatibility bridge keeps classic 1.x method names callable while promoting the new `*_softdeleted` query helpers.
+- Documentation site rebuilt in VitePress with end-to-end guides, quick reference material, and real-world walkthroughs.
+
+### Added
+- Updated query builder with snake_case and camelCase parity, constraint-aware eager loading (`with()`), lazy collections, streaming/chunking helpers, and advanced query composition (subqueries, raw expressions, grouped clauses).
+- Soft delete tooling: `SoftDeletes` trait, `HasTimestamps` integration, `with_softdeleted()` / `only_softdeleted()` / `without_softdeleted()` helpers, and camelCase aliases for interoperability.
+- Composer metadata (`composer.json`, `composer.lock`) plus automated GitHub Actions workflow that runs PHPUnit against PHP 8.1 – 8.5.
+- Comprehensive PHPUnit coverage for soft delete behaviour, query builder helpers, caching harnesses, and wrapper utilities.
+
+### Changed
+- Promoted soft delete coordination flags to public properties for builder access and aligned trait, builder, and model implementations.
+- Refreshed internal casting, attribute bootstrap, and nested set utilities to leverage 2.0 constructs while maintaining backwards compatibility.
+- CI matrix now exercises PHP 8.1, 8.2, 8.3, 8.4, and 8.5 to track forthcoming runtime changes.
+- Expanded error handling with typed exceptions and more descriptive stack traces in non-CodeIgniter environments.
+
+### Removed
+- Retired the bundled CodeIgniter demo app under `/examples` in favour of documentation-native samples and focused unit coverage.
+
+### Fixed
+- Hardened soft delete scope resolution across eager loading callbacks and relationship queries.
+- Resolved method signature mismatches identified by PHP 8.x, preventing fatal errors in mixed environments.
+- Stabilised many-to-many join detection, cached table lookups, and debug logging suppression.
+
+### Documentation
+- Replaced ad-hoc markdown with a structured VitePress knowledge base covering getting started, advanced topics, reference material, and troubleshooting.
+- Added migration notes, modernization roadmaps, and quick-start guides that reflect the 2.0 helper naming and patterns.
+
+### Migration Notes
+- Existing 1.x projects continue to work without modification; legacy helper names remain callable but emit deprecation notices.
+- Prefer chaining the new snake_case helpers (`with_softdeleted()`, `only_softdeleted()`, `without_softdeleted()`) or their camelCase aliases when integrating with `SoftDeletes`.
+- Run the bundled PHPUnit suite (`vendor/bin/phpunit -c tests/phpunit.xml`) after upgrading to verify trait and builder integrations.
