-## Project
-
-Smarty v5 — PHP template engine. Single Composer package (`smarty/smarty`), namespace `Smarty\`, source in `src/`, autoloaded via PSR-4. Supports PHP 7.2–8.5.
-
-Do not use PHP syntax newer than 7.2 in `src/` unless it is guarded for older runtimes.
-
-## Commands
-
-```bash
-# Install dependencies
-composer install
-
-# Regenerate lexers and parsers (required before tests; CI runs this)
-make -B
-
-# Run all tests
-php ./vendor/phpunit/phpunit/phpunit
-
-# Run a single test file
-php ./vendor/phpunit/phpunit/phpunit tests/UnitTests/TemplateSource/TagTests/If/CompileIfTest.php
-
-# Run tests matching a PHPUnit group
-php ./vendor/phpunit/phpunit/phpunit --group 20221124
-
-# Run tests excluding slow group
-php ./vendor/phpunit/phpunit/phpunit --exclude-group slow
-```

-There is no linter or static analysis configured. No typecheck step.
-
-## Generated code — do not hand-edit
-
-Four files are generated from grammar/lexer definitions via `make`:
-
-| Source (edit this) | Generated (do not edit) |
-|---|---|
-| `src/Lexer/TemplateLexer.plex` | `src/Lexer/TemplateLexer.php` |
-| `src/Lexer/ConfigfileLexer.plex` | `src/Lexer/ConfigfileLexer.php` |
-| `src/Parser/TemplateParser.y` | `src/Parser/TemplateParser.php` |
-| `src/Parser/ConfigfileParser.y` | `src/Parser/ConfigfileParser.php` |
-
-After editing a `.plex` or `.y` file, run `make -B` to regenerate. The generators require the `smarty/smarty-lexer` dev dependency.
-
-## Architecture
-
-- `src/Smarty.php` — main class, extends `TemplateBase`. Version constant: `Smarty::SMARTY_VERSION`.
-- `src/Compile/`, `src/Compiler/` — template compilation pipeline.
-- `src/Lexer/`, `src/Parser/` — lexer/parser (generated, see above).
-- `src/Extension/` — extension system (`ExtensionInterface`, `CoreExtension`, `DefaultExtension`, `BCPluginsAdapter`).
-- `src/Runtime/` — runtime helpers (foreach, capture, inheritance, tpl functions).
-- `src/Resource/`, `src/Cacheresource/` — template resource and cache resource handlers.
-- `src/BlockHandler/`, `src/FunctionHandler/`, `src/Filter/` — built-in tags, functions, and filters.
-- `libs/Smarty.class.php` — non-Composer autoload stub. Points to `src/`. Not the main source.
-- `src/functions.php` — global helper functions, always loaded via Composer `files` autoload.
-
-## Tests
-
-- Framework: PHPUnit 7.5/8.5 (bootstrap: `tests/Bootstrap.php`).
-- All tests extend `PHPUnit_Smarty` (defined in `tests/PHPUnit_Smarty.php`), which provides `setUpSmarty($dir)`.
-- Test suite root: `tests/UnitTests/`. Typical test `setUp()` calls `$this->setUpSmarty(__DIR__)`.
-- Each test directory may have its own `templates/`, `configs/` subdirectories. Compiled output goes to `templates_c/` and `cache/` (auto-created by the test harness).
-- Running the suite scatters generated `templates_c/`, `cache/`, and `templates_tmp/` directories (and empty runtime `templates/`/`configs/` dirs) throughout `tests/` and the repo root. These are not tracked — treat them as noise in `git status`, never commit them, and clean them with `git clean -fd` (exclude tool dirs like `.serena`).
-- Three test files are excluded in `phpunit.xml`: Memcache, APC, and HttpModifiedSince tests (require external services).
-- Tests needing MySQL/PDO are gated by constants in `tests/Config.php` (disabled by default).
-
-## CI
-
-GitHub Actions (`.github/workflows/ci.yml`): matrix of PHP 7.2–8.5 on ubuntu + windows. Steps: `composer install` → `make -B` → `phpunit`. No deploy step.
-
-## Docs
-
-Markdown in `docs/`, built with mkdocs + Material theme. Install the toolchain with `pip install -r docs/requirements.txt`, then preview with `mkdocs serve`. Published via `mike deploy 5.x`.
-
-## Release
-
-`./make-release.sh <version>` — only v5.x.x. Updates changelog and version constant, creates a merge commit and tag on `master`.
-
-### Changelog
-
-Every change that should appear in `CHANGELOG.md` must add a new markdown file under `changelog/`. At release time `utilities/update-changelog.php` concatenates all `changelog/*.md` files into the `## [Unreleased]` section, so:
-
-- One file per change, containing a single line that starts with a dash (`- ...`). The filename is arbitrary; name it after the issue number (e.g. `1036.md`) when there is one, otherwise use a short descriptive slug.
-- Include a markdown link to the relevant issue when one exists, e.g. `[#1036](https://github.com/smarty-php/smarty/issues/1036)`. Omit the link when there is no public issue (e.g. embargoed security reports).

 ## [Unreleased]
 
-## [5.8.4] - 2026-06-29
-- Fixed a `TypeError` on PHP 8 when `Security::$static_classes` was set to a non-array value (e.g. the string `'none'`) to disable static class access; any non-array value now cleanly denies access. Use `Security::$static_classes = null` to disable access to all static classes.
-- Security: the built-in `stream:` resource type now validates the nested stream wrapper against the security policy, so a template such as `stream:php://filter/...` can no longer bypass `Security::$streams` (including `Security::$streams = null`) to read local files (CWE-22)
-
-
-## [5.8.3] - 2026-06-28
-- fixed a regression from #1189 where a child template's block override no longer applied to a template {include}d by the parent [#1192](https://github.com/smarty-php/smarty/issues/1192)
-
-
-## [5.8.2] - 2026-06-24
-- Security: prevent symlinks inside a trusted `secure_dir`/template directory from being used to read files outside of it (CWE-22 path traversal), affecting `{include}` and `{fetch}` of local files
-- Security: `{html_image}` now escapes the `file`, `path_prefix`, `href`/`link`, `width` and `height` attributes (it already escaped `alt` and pass-through attributes), and `{html_select_date}` casts `day_size`/`month_size`/`year_size` to int (matching `{html_select_time}`), preventing untrusted values passed into these attributes from breaking out of the generated HTML (CWE-79)
-- Security: `{fetch}` no longer follows HTTP redirects for remote resources while a security policy is active, preventing an open redirect on a trusted host from bypassing `trusted_uri` (CWE-918 server-side request forgery)
-- Fixed "Attempt to assign property step on null" error when using a {for} loop inside a block of an extended template [#1036](https://github.com/smarty-php/smarty/issues/1036)
-
-
-## [5.8.1] - 2026-06-23
-- Re-activated unit tests for user literals, which were previously disabled due to a bug in refactoring to v5.
-- fixed a bug where child template's block content leaked into subsequent rendering of the parent template [#1189](https://github.com/smarty-php/smarty/issues/1189)
-- Moved all unit test-generated output from inside the working tree to tmp files [#1178](https://github.com/smarty-php/smarty/issues/1178)
-
-
-## [5.8.0] - 2026-02-15
-- Added support for Backed Enums for php versions >= 8.1 [#1171](https://github.com/smarty-php/smarty/pull/1171)
-- Added support for new 'matches' operator doing regex matching [#1169](https://github.com/smarty-php/smarty/pull/1169)
-- Update documentation to clarify that include inline is currently not implemented in Smarty v5 [#1152](https://github.com/smarty-php/smarty/issues/1152)
