+## [2.2.0] - 2026-10-08 - Route Syntax & DX Edition
+
+> Includes the PSR-7 2.0 compatibility fix documented below under `[2.1.1]`
+> (that patch release was never tagged; its changes ship in 2.2.0).
+
+### Added
+
+- **Brace-delimited route parameters** (`{id}` and `{id<constraint>}`) work end-to-end,
+  equivalent to the colon syntax (`:id`). Requires `pivotphp/core-routing` `^1.2`.
+  ([SPEC-002](https://github.com/PivotPHP/pivotphp-specs/blob/main/SPECS/SPEC-002-brace-params.md))
+- **Array callables `[Classe::class, 'métodoDeInstância']`** resolve via the DI container
+  (falling back to lazy instantiation) instead of throwing `InvalidArgumentException`.
+  ([SPEC-003](https://github.com/PivotPHP/pivotphp-specs/blob/main/SPECS/SPEC-003-array-callable.md))
+- **`Request::body()`** method — Express-style accessor returning the parsed body as
+  `stdClass` (alias of `getBodyAsStdClass()`).
+  ([SPEC-004](https://github.com/PivotPHP/pivotphp-specs/blob/main/SPECS/SPEC-004-request-body.md))
+- **SQLite support in `Database::connect()`** (`driver => 'sqlite'`,
+  `database => '<path>'|':memory:'`).
+  ([SPEC-005](https://github.com/PivotPHP/pivotphp-specs/blob/main/SPECS/SPEC-005-database-sqlite.md))
+- **`PivotPHP\Core\Application` backward-compatibility alias** to
+  `PivotPHP\Core\Core\Application`.
+  ([SPEC-001](https://github.com/PivotPHP/pivotphp-specs/blob/main/SPECS/SPEC-001-application-fqcn.md))
+
+### Fixed
+
+- `getBodyAsStdClass()` no longer discards the body on `DELETE` requests.
+  ([SPEC-006](https://github.com/PivotPHP/pivotphp-specs/blob/main/SPECS/SPEC-006-delete-body.md))
+
+### Changed
+
+- `pivotphp/core-routing` dependency bumped from `^1.0` to `^1.2`.

+# PivotPHP v2.2.0 - Framework Overview
+
+**Version:** 2.2.0 (Route Syntax & DX Edition)
+**Release Date:** 2026-10-08
+**PHP Requirements:** 8.1+
+
+---
+
+## 🎯 Executive Summary
+
+PivotPHP v2.2.0 is a **minor release** focused on developer experience and routing
+flexibility. It adds brace-delimited route parameters (`{id}`) as an alternative to the
+colon syntax, resolves instance-method array callables through the DI container, introduces
+the Express-style `Request::body()` accessor, and adds SQLite support to the `Database`
+wrapper — while keeping full backward compatibility.
+
+> This release also ships the PSR-7 2.0 compatibility fix that was previously recorded
+> under `[2.1.1]` but never tagged.
+
+### Release Highlights
+
+- ✅ **Brace route parameters** (`{id}` / `{id<constraint>}`) — equivalent to `:id`.
+- ✅ **Array callables `[Classe::class, 'métodoDeInstância']`** resolved via DI container.
+- ✅ **`Request::body()`** — Express-style body accessor.
+- ✅ **SQLite support** in `Database::connect()`.
+- ✅ **`PivotPHP\Core\Application`** backward-compatibility alias.
+- ✅ **PSR-7 2.0** (`psr/http-message` `^1.1|^2.0`) dual support (carried from 2.1.1).
+
+---
+
+## 🏗️ What Changed
+
+### 1. Route Parameters — `{id}` syntax
+
+Routes now accept both `:id` and `{id}` (with optional constraint `{id<\d+>}`), backed by
+the same constraint/shortcut/ReDoS validation in the routing engine. Requires
+`pivotphp/core-routing` `^1.2`.
+
+```php
+$app->get('/users/:id', fn($req, $res) => $res->json(['id' => $req->param('id')]));
+$app->get('/books/{isbn}', fn($req, $res) => $res->json(['isbn' => $req->param('isbn')]));
+```
+
+### 2. Array Callables with Instance Methods
+
+`[UserController::class, 'index']` now resolves the instance through the DI container when
+registered, and falls back to lazy instantiation otherwise (previously threw
+`InvalidArgumentException` for non-static methods).
+
+### 3. Request Body Access
+
+`Request::body()` returns the parsed body as `stdClass` (alias of `getBodyAsStdClass()`).
+`getBodyAsStdClass()` no longer discards the body on `DELETE` requests.
+
+### 4. Database SQLite
+
+`Database::connect()` supports `driver => 'sqlite'` (`database` = path or `:memory:`), in
+addition to MySQL/MariaDB/PostgreSQL via host/port.
+

+
+## 📊 Technical Metrics
+
+| Metric | v2.2.0 |
+|--------|--------|
+| **PSR-7** | `psr/http-message` `^1.1\|^2.0` (dual support) |
+| **PSR-15** | Compliant |
+| **PSR-3** | `Logging\PsrLogger` |
+| **PSR-11** | `Providers\Container` |
+| **PSR-14** | `Events\EventDispatcher` |
+| **PHPStan** | Level 9 |
+| **Coding style** | PSR-12 |
+| **Tests** | 1092 CI + 34 integration |
+
+### Performance
+
+PivotPHP v2.2.0 maintains the performance characteristics of the v2.x line (object pooling,
+JSON optimization, route caching). The new `{id}` syntax compiles to the same regex patterns
+as `:id`, so there is no matching-time regression. The array-callable container resolution
+happens once at route registration, not per request.
+
+---
+
+## 🔧 Compatibility
+
+- **Backward compatible** with v2.x — `:id` syntax, static array callables, and instance
+  array callables all keep working.
+- `pivotphp/core-routing` bumped from `^1.0` to `^1.2`.
