v2.3.0

• Added Internal\Materialization and refactored EagerPipeline to rely on it for cached terminal access.
• Expanded/adjusted complexity and evaluation-strategy documentation (Collectible, Pipeline, README).
• Added test coverage for multi-predicate filtering and reducing over chained operations (eager + lazy).

v2.2.0

• Introduce Collection::createFromClosure() backed by an eager pipeline that materializes the closure result immediately.
• Move first/isEmpty/last resolution into Pipeline implementations (eager/lazy) and remove the old resolving helpers.
• Expand README + API docs with evaluation strategy and complexity explanations; add extensive tests and new test models.

v2.1.0

• Introduces Collection::createLazyFromClosure() backed by LazyPipeline::fromClosure() for re-iterable lazy sources.
• Refactors EagerPipeline to memoize materialization and allow repeated iteration when created from single-use iterables (e.g., generators).
• Updates each() to be a terminal operation returning void, and updates tests + adds new tests for closure/generator reiteration.

v2.0.0

• Introduces Pipeline + EagerPipeline/LazyPipeline and refactors Collection to compose operations via pipeline stages.
• Replaces the previous operation set (LazyOperation/ImmediateOperation) with Transforming\* (pipeline stages) and Resolving\* (terminal helpers).
• Consolidates/rewrites tests and updates documentation to reflect the new API and extension patterns.

v1.16.0

• Introduces Collectible::merge() and implements it in Collection.
• Adds a new lazy write operation Internal\Operations\Write\Merge.
• Adds unit tests and README documentation for merging collections.

v1.15.0

• Updates dependencies and remove unused extensions in CI configuration.

v1.14.0

• Move operation test files to new structure under Internal\Operations\.
• Update namespaces in test files to reflect new structure.
• Refactor Slice.php buffered slicing to use SplQueue for efficiency and clarity.
• Enhance docblocks in Collectible.php with complexity notes and clarify groupBy return type.

v1.13.1

• Fixes descending sort to always reverse predicate arguments, ensuring correct order.
• Adds unit test for sorting collection in descending order using a custom predicate.
• Updates README formatting for consistency.
• Refactors joinTo method for improved separator handling.

v1.13.0

• Remove redundant array_first/array_last usage in First.php and Last.php operations.
• Move test classes to Test\TinyBlocks\Collection namespaces for consistency.
• Update autoload-dev PSR-4 mapping in composer.json.
• Bump tiny-blocks/mapper to 1.4.* and add tiny-blocks/currency to require-dev.
• Update Makefile test-file usage instructions.
• Adjust imports in test files to reflect namespace changes.

v1.12.0

• Bump PHP requirement to 8.5 and update dependencies in composer.json and Docker image.
• Refactor all closures to use static where possible for performance and clarity.
• Optimize Filter, First, Last, and Find operations for better lazy evaluation and early termination.
• Enhance Slice to handle negative lengths and improve memory efficiency.
• Update CI workflow for artifact-based dependency caching and PHP 8.5.
• Improve Makefile with help target, colorized output, and updated Docker image.
• Remove unused phpmd references and update .gitattributes.
• Update documentation and tests to reflect static closures and new behaviors.
