# Change Log

All notable changes to this project will be documented in this file. This project adhere to the [Semantic Versioning](http://semver.org/) standard.

## [1.3.0] - 2026-02-25

### Added
- Transaction nesting support via savepoints. Nested `beginTransaction()` calls now create savepoints instead of issuing `START TRANSACTION`, which would implicitly commit any existing transaction.
- `DB::transactionLevel()` method to retrieve the current transaction nesting depth.

### Changed
- `DB::commit()` releases the current savepoint when nested, and issues a real `COMMIT` only at the outermost level.
- `DB::rollback()` rolls back to the current savepoint when nested, and issues a real `ROLLBACK` only at the outermost level.
- `tests-php.yml` ensure slic runs in PHP 7.4.
