Problem
The repository has no CHANGELOG, CONTRIBUTING guide, security policy, or issue/PR templates, so contributors have no documented expectations and the 2.0 changes have no user-facing history beyond release notes.
Changes
CHANGELOG.mdin Keep a Changelog format: the 2.0 changes (Current locale must be one of the kernel.enabled_locales #71, chore(composer): widen dependency ranges and alias master as 2.0-dev #76, docs(readme): modernize examples and badges #77, chore(quality): add PHPStan level 6 and php-cs-fixer, fix all findings #78) under Unreleased with BREAKING markers pointing at UPGRADE-2.0.md, brief 1.4.1/1.4 history, and a link to the releases page for older versions.CONTRIBUTING.md: setup, the four quality gates, and PR expectations (what counts as public API, UPGRADE and CHANGELOG duties).SECURITY.md: private reporting channel and a supported-versions table (2.x supported, 1.4.x security fixes only).
