+
+## 🎯 Datenmodell
+
+### Events ↔ EventOccurrences (1:N Beziehung)
+
+Ein **Event** ist eine Veranstaltung mit stabilen Eigenschaften:
+- `title`, `description`, `location`, `category`
+- `slug` (für SEO-URLs)
+- `status` (draft, published, archived)
+
+Ein **EventOccurrence** ist ein einzelner Termin mit Zeitinformation:
+- `start_datetime`, `end_datetime`
+- `is_all_day` (ganztägig?)
+- `location_details` (z.B. "Saal A")
+- `capacity`, `available_tickets`
+- `price`
+- `status` (scheduled, cancelled, completed)
+
+### Beispiel:
+```
+📌 Event: "Ostermarkt auf der Altstadt"
+   ├─ 🗓️ Occurrence 1: Sa 18.04., 10:00-18:00 (Kapazität: 1000)
+   ├─ 🗓️ Occurrence 2: So 19.04., 10:00-18:00 (Kapazität: 1000)
+   └─ 🗓️ Occurrence 3: Mo 20.04., 10:00-18:00 (Kapazität: 800)
+```
+
+## 📊 Import-Workflow
+
+```
+External Source (API/Scraper)
+        ↓
+   ImportEventsCommand
+        ↓
+   ImportEventsJob (Queue)
+        ↓
+   upsertEvent() [updateOrCreate]
+        ↓
+   upsertOccurrences() [updateOrCreate]
+        ↓
+   Database (MariaDB)
+        ↓
+   REST API
+```
+
+**Upsert-Logik:**
+- Events werden anhand `[source_id, external_id]` abgeglichen
+- Existierende Events werden aktualisiert
+- Neue Events werden angelegt
+- Verhindert Duplikate durch Unique Index
+
+## ⏰ Geplante Imports (Scheduler)
+
+Die Integration mit Laravel Scheduler (tägliche Cron-Regel):
+
+```
+03:00 Uhr  → Täglich alle Quellen importieren
+Stündlich  → Stadt-Dresden-Quelle (häufige Updates)
+Alle 6h    → Andere Quellen
+04:00 Uhr  → Markiere abgelaufene Termine
+Sonntag    → Archive alte Events
+```
+
+Weitere Details: 👉 [IMPORT_SCRAPER_INTEGRATION.md](docs/IMPORT_SCRAPER_INTEGRATION.md)
+
+## 🛠️ Commands & Artisan
+
+```bash
+# Manueller Import
+php artisan events:import [--source=ID|Name] [--sync]
+
+# Queue Worker starten
+php artisan queue:work --verbose
+
+# Scheduler testen (nur für Entwicklung)
+php artisan schedule:run
+
+# Queue debuggen
+php artisan queue:failed
+php artisan queue:retry {id}
+php artisan queue:flush
+```
+
+## 🔐 Best Practices (implementiert)
+
+✅ **Datenbank-Design:**
+- Foreign Keys mit CASCADE DELETE
+- Composite Indizes für häufige Filter-Kombinationen
+- Unique Index auf `[source_id, external_id]` gegen Duplikate
+- MariaDB-spezifische Optimierungen (InnoDB Engine, utf8mb4)
+
+✅ **Code-Qualität:**
+- Eloquent Models mit Relationships & Scopes
+- Type Hints (PHP 8.2+)
+- Request Validation
+- Error Logging
+- Transaction Support
+
+✅ **Performance:**
+- Query Optimization mit eager loading (`.with()`)
+- Effiziente Composite Indizes
+- Pagination für API-Response
+- Queue-basierte Background Jobs
+
+✅ **Wartbarkeit:**
+- Service-Layer für Business Logic
+- Commands für CLI-Interface
+- Job-Klassen für Queue-Verarbeitung
+- Dokumentierte Code-Beispiele
+
+## 🚀 Production Deployment
+
+1. **Queue Worker setup** (Supervisor)
+2. **Scheduler Cron-Job** (täglicher Scheduler:run)
+3. **Redis/Beanstalkd** für Queue (statt database)
+4. **Error Monitoring** (Sentry, etc.)
+5. **Backup** vor Production-Launch
+
+Siehe: 👉 [SETUP.md - Production Deployment](docs/SETUP.md)
+
+## 📚 Beispiele
+
+### Query: "Nächste 10 Events in Dresden"
+```php
+$events = Event::published()
+    ->byLocation('Dresden')
+    ->with(['occurrences' => function ($q) {
+        $q->upcoming()->limit(1);
+    }])
+    ->limit(10)
+    ->get();
+```
+
+### Query: "Alle Events am 15. April"
+```php
+$date = Carbon::parse('2026-04-15');
+$events = Event::published()
+    ->with(['occurrences' => function ($q) use ($date) {
+        $q->onDate($date)->scheduled();
+    }])
+    ->whereHas('occurrences', function ($q) use ($date) {
+        $q->onDate($date)->scheduled();
+    })
+    ->get();
+```
+
+Weitere: 👉 [EXAMPLE_QUERIES.php](docs/EXAMPLE_QUERIES.php)
+
+## 🤝 Integration Beispiele
+
+### Stadt-Dresden-API
+```php
+$response = Http::get('https://api.stadt-dresden.de/events', [
+    'limit' => 1000,
+]);
+```
+
+### Web-Scraping
+```bash
+composer require symfony/dom-crawler
+```
+
+### Google-Calendar (iCal)
+```php
+$feed = file_get_contents('https://calendar.google.com/.../basic.ics');
+// Parse mit Spatie iCalendar Parser
+```
+
+## 🐛 FAQ & Troubleshooting
+
+**F: Migrations schlagen fehl**
+```bash
+A: MariaDB Version checken, dann:
+   php artisan migrate:refresh
+   php artisan migrate
+```
+
+**F: Queue-Jobs werden nicht verarbeitet**
+```bash
+A: Worker-Prozess nicht laufend?
+   php artisan queue:work --verbose
+```
+
+**F: API gibt 404 zurück**
+```bash
+A: php artisan serve
+   dann http://localhost:8000/api/events testen
+```

+# Import & Scraper-Integration für Laravel Event-Portal
+
+## 📌 Übersicht
+
+Die App unterstützt mehrere Integrationsoptionen für den Event-Import:
+
+1. **Commands** - Manuelle, einmalige Imports via Artisan-CLI
+2. **Queue Jobs** - Asynchrone, warteschlangen-basierte Imports
+3. **Scheduler** - Geplante, regelmäßige Imports (z.B. täglich)
+4. **Webhooks/Events** - Echtzeit-Updates von externen Quellen
+
+---
+
+## 🔧 Setup-Schritte
+
+### 1. Abhängigkeiten installieren
+
+```bash
+# Für HTTP-Requests (externe APIs)
+composer require laravel/http-client
+
+# Für Web-Scraping (optional)
+composer require symfony/dom-crawler symfony/http-client
+
+# Für erweiterte Logging/Monitoring (optional)
+composer require sentry/sentry-laravel
+```
+
+### 2. Queue-Konfiguration
+
+Bearbeite `.env`:
+```env
+QUEUE_CONNECTION=database  # oder redis, beanstalkd, etc.
+```
+
+Erstelle Queue-Tabelle:
+```bash
+php artisan queue:table
+php artisan migrate
+```
+
+### 3. Sources erstellen
+
+Füge über Seeder oder Admin-Interface Source-Records hinzu:
+
+```php
+// database/seeders/SourceSeeder.php
+
+use App\Models\Source;
+use Illuminate\Database\Seeder;
+
+class SourceSeeder extends Seeder
+{
+    public function run()
+    {
+        Source::create([
+            'name' => 'Stadt Dresden',
+            'description' => 'Offizielle Veranstaltungen der Landeshauptstadt Dresden',
+            'url' => 'https://stadt-dresden.de/veranstaltungen',
+            'status' => 'active',
+        ]);
+
+        Source::create([
+            'name' => 'Kulturzentrum Hellerau',
+            'description' => 'Veranstaltungen des Kulturzentrums Hellerau',
+            'url' => 'https://hellerau.org',
+            'status' => 'active',
+        ]);
+    }
+}
+```
+
+Starten:
+```bash
+php artisan db:seed --class=SourceSeeder
+```
+
+---
+
+## 👨‍💻 Verwendung
+
+### Option 1: Manueller Import via Command
+
+```bash
+# Alle aktiven Quellen importieren (asynchron)
+php artisan events:import
+
+# Nur eine spezifische Quelle (nach ID)
+php artisan events:import --source=1
+
+# Oder nach Name
+php artisan events:import --source="Stadt Dresden"
+
+# Synchron (blocking) ausführen
+php artisan events:import --sync
+```
+
+### Option 2: Programmgesteuert im Code
+
+```php
+// In einem Controller, Service oder Command:
+
+use App\Jobs\ImportEventsJob;
+use App\Models\Source;
+use App\Services\EventImportService;
+
+// Via Service
+$importService = app(EventImportService::class);
+$importService->importFromAllSources($synchronous = false);
+
+// Oder direkt Job Dispatchen
+$source = Source::find(1);
+ImportEventsJob::dispatch($source);  // Asynchron
+ImportEventsJob::dispatchSync($source);  // Synchron
+```
+
+### Option 3: Queue Worker ausführen
+
+Damit die Jobs in der Queue abgearbeitet werden:
+
+```bash
+# Development: Ein Worker mit verbose Output
+php artisan queue:work --verbose
+
+# Production: Daemon-Mode mit Auto-Restart
+php artisan queue:work --daemon --tries=3 --timeout=120
+
+# Mit Supervisor für permanente Worker (Production)
+# Siehe: https://laravel.com/docs/queues#supervisor-configuration
+```
+
+---
+
+## ⏰ Scheduler-Integration
+
+### Täglicher Import via Scheduler
+
+Bearbeite `app/Console/Kernel.php`:
+
+```php
+<?php
+
+namespace App\Console;
+
+use App\Jobs\ImportEventsJob;
+use App\Models\Source;
+use Illuminate\Console\Scheduling\Schedule;
+use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
+
+class Kernel extends ConsoleKernel
+{
+    /**
+     * Register the commands for the application.
+     */
+    protected function commands()
+    {
+        $this->load(__DIR__.'/Commands');
+        require base_path('routes/console.php');
+    }
+
+    /**
+     * Define the application's command schedule.
+     */
+    protected function schedule(Schedule $schedule)
+    {
+        // ===== EVENT-IMPORTS =====
+
+        // Täglicher Import um 03:00 Uhr nachts
+        $schedule->command('events:import')
+            ->dailyAt('03:00')
+            ->name('events.daily_import')
+            ->onFailure(function () {
+                \Illuminate\Support\Facades\Log::error('Daily event import failed');
+            })
+            ->onSuccess(function () {
+                \Illuminate\Support\Facades\Log::info('Daily event import completed');
+            });
+
+        // Zusätzlich: Stündliche Importe (z.B. für häufig aktualisierte Quellen)
+        $schedule->command('events:import --source="Stadt Dresden"')
+            ->hourly()
+            ->name('events.hourly_import_dresden');
+
+        // ===== CLEANUP & MAINTENANCE =====
+
+        // Lösche abgelaufene Termine täglich
+        $schedule->call(function () {
+            \App\Models\EventOccurrence::where('status', 'scheduled')
+                ->where('end_datetime', '<', now())
+                ->update(['status' => 'completed']);
+        })
+        ->daily()
+        ->at('04:00')
+        ->name('events.mark_completed');
+
+        // Lösche verwaiste Events ohne Termine
+        $schedule->call(function () {
+            \App\Models\Event::doesntHave('occurrences')
+                ->where('status', 'published')
+                ->where('created_at', '<', now()->subMonths(1))
+                ->update(['status' => 'archived']);
+        })
+        ->weekly()
+        ->name('events.cleanup_orphaned');
+
+        // Runnable: Optional - teste dieSchedulerkonfiguration
+        if (app()->environment('local')) {
+            $schedule->command('inspire')->hourly();
+        }
+    }
+
+    /**
+     * Get the timezone that should be used by default for scheduled events.
+     */
+    protected function scheduleTimezone(): string
+    {
+        return 'Europe/Berlin';
+    }
+}
+```
+
+### Scheduler im Production einrichten
+
+Für Production brauchst du einen Cron-Job, der den Scheduler jede Minute aufruft:
+
+```bash
+# Crontab editieren
+crontab -e
+
+# Folgendes hinzufügen:
+* * * * * cd /path/to/app && php artisan schedule:run >> /dev/null 2>&1
+```
+
+Oder mit systemd-Timer (Modern Alternative):
+
+```ini
+# /etc/systemd/system/laravel-scheduler.service
+[Unit]
+Description=Laravel Artisan Scheduler
+Requires=laravel-scheduler.timer
+
+[Service]
+Type=oneshot
+User=www-data
+ExecStart=/usr/bin/php /path/to/app/artisan schedule:run
+```
+
+---
+
+## 🔌 API-Integration: Beispiele für externe Quellen
+
+### Stadt Dresden API
+
+```php
+// In ImportEventsJob::fetchExternalEvents()
+
+use Illuminate\Support\Facades\Http;
+
+$response = Http::withHeaders([
+    'Accept' => 'application/json',
+    'User-Agent' => 'Dresden-EventPortal/1.0',
+])->get('https://api.stadt-dresden.de/v1/events', [
+    'limit' => 1000,
+    'filter[status]' => 'published',
+]);
+
+$events = $response->json('data');
+```
+
+### iCal-Feed (z.B. von Google Calendar)
+
+```php
+use Spatie\IcalendarParser\InvitationParser;
+
+$feed = file_get_contents('https://calendar.google.com/calendar/ical/.../public/basic.ics');
+$event = InvitationParser::parse($feed);
+
+foreach ($event as $entry) {
+    $events[] = [
+        'external_id' => $entry['uid'],
+        'title' => $entry['summary'],
+        'location' => $entry['location'] ?? 'TBD',
+        'description' => $entry['description'] ?? null,
+        'occurrences' => [
+            [
+                'start_datetime' => $entry['dtstart'],
+                'end_datetime' => $entry['dtend'] ?? null,
+            ]
+        ]
+    ];
+}
+```
+
+### Web-Scraping mit DOM-Crawler
+
+```php
+use Symfony\Component\DomCrawler\Crawler;
+use Symfony\Component\HttpClient\HttpClient;
+
+$client = HttpClient::create();
+$response = $client->request('GET', 'https://example.com/events');
+$html = $response->getContent();
+
+$crawler = new Crawler($html);
+$events = [];
+
+$crawler->filter('.event-card')->each(function (Crawler $event) use (&$events) {
+    $events[] = [
+        'external_id' => $event->filter('[data-event-id]')->attr('data-event-id'),
+        'title' => $event->filter('.event-title')->text(),
+        'description' => $event->filter('.event-desc')->text(),
+        'location' => $event->filter('.event-location')->text(),
+        'occurrences' => [
+            [
+                'start_datetime' => $event->filter('[data-date]')->attr('data-date'),
+            ]
+        ]
+    ];
+});
+```
+
+---
+
+## 🔄 Upsert-Logik erklärt
+
+Die App verwendet Laravel's `updateOrCreate()` für Event-Duplikat-Handling:
+
+```php
+// Suche Event mit (source_id, external_id)
+// Falls existiert: Update mit neuen Daten
+// Falls nicht: Erstelle neuen Record
+
+$event = Event::updateOrCreate(
+    [
+        'source_id' => $source->id,
+        'external_id' => $externalData['external_id'],
+    ],
+    [
+        'title' => $externalData['title'],
+        'description' => $externalData['description'] ?? null,
+        'location' => $externalData['location'],
+        // ... mehr Felder
+    ]
+);
+
+if ($event->wasRecentlyCreated) {
+    // Neuer Event
+} else {
+    // Event aktualisiert
+}
+```
+
+**Vorteile:**
+- ✅ Verhindert Duplikate (unique index auf `[source_id, external_id]`)
+- ✅ Aktualisiert existierende Events
+- ✅ Einfaches Handling bei mehreren Importen
+- ✅ Atomare Operation (transaktional)
+
+---
+
+## 📊 Monitoring & Logging
+
+### Job-Übersicht
+
+```bash
+# Anstehende Jobs in der Queue anschauen
+php artisan queue:work --verbose
+
+# Log-Output für Failure
+tail -f storage/logs/laravel.log | grep ImportEventsJob
+```
+
+### Custom Queue-Monitor Dashboard
+
+```php
+// Beispiel: Dashboard für laufende Imports
+
+Route::get('/admin/imports', function () {
+    $failed = \Illuminate\Support\Facades\DB::table('failed_jobs')
+        ->where('queue', 'default')
+        ->latest()
+        ->limit(20)
+        ->get();
+
+    $pending = \Illuminate\Support\Facades\DB::table('jobs')
+        ->where('queue', 'default')
+        ->count();
+
+    return response()->json([
+        'pending_jobs' => $pending,
+        'failed_jobs' => $failed,
+    ]);
+});
+```
+
+---
+
+## 🚀 Best Practices
+
+### 1. Skalierung bei vielen Events
+
+Für große Mengen an Events (1000+) pro Import:
+- Nutze **Chunking**: `$externalEvents->chunk(100)`
+- **Batch-Processing** mit `InsertOnDuplicateKeyUpdateCommand`
+- Disable **Query Logging** im Job
+
+```php
+// In handle():
+\Illuminate\Support\Facades\DB::disableQueryLog();
+
+foreach ($externalEvents->chunk(100) as $chunk) {
+    foreach ($chunk as $event) {
+        $this->upsertEvent($event);
+    }
+}
+```
+
+### 2. Error Handling & Retries
+
+```php
+// In ImportEventsJob versuchweise 3x erneut:
+class ImportEventsJob implements ShouldQueue
+{
+    public $tries = 3;
+    public $backoff = [60, 300, 900]; // Backoff: 1min, 5min, 15min
+}
+```
+
+### 3. Rate Limiting für externe APIs
+
+```php
+use Illuminate\Support\Facades\RateLimiter;
+
+protected function fetchExternalEvents()
+{
+    return RateLimiter::attempt(
+        'dresden-api-import',
+        $perMinute = 10,
+        function () {
+            return Http::get('https://api.stadt-dresden.de/events')->json();
+        },
+        $decay = 60
+    );
+}
+```
+
+### 4. Transaction für Atomarität
+
+```php
+use Illuminate\Support\Facades\DB;
+
+DB::transaction(function () {
+    foreach ($externalEvents as $externalEvent) {
+        $this->upsertEvent($externalEvent);
+    }
+});
+```
+
+---
+
+## 🔍 Troubleshooting
+
+### Queue-Jobs werden nicht verarbeitet
+
+```bash
+# 1. Checke Queue-Konfiguration
+php artisan config:show queue
+
+# 2. Starte einem Artisan Queue Worker
+php artisan queue:work
+
+# 3. Prüfe failed_jobs table
+php artisan queue:failed
+```
+
+### Import schlägt fehl - Externe API nicht erreichbar
+
+```php
+// Nutze Http withoutVerifying für HTTPS-Fehler (nur dev!)
+Http::withoutVerifying()->get('https://...');
+
+// Oder mit Custom Timeout
+Http::timeout(30)->get('https://...');
+```
+
+### Duplicate Key Errors
+
+```php
+// Prüfe Unique Index:
+DB::raw('SHOW INDEX FROM events')
+
+// Falls fehlt:
+Schema::table('events', function (Blueprint $table) {
+    $table->unique(['source_id', 'external_id']);
+});
+```

+
+## ⚙️ Installation & Setup
+
+### 1. Frisches Laravel-Projekt erstellen
+
+```bash
+# Laravel 11 LTS (oder aktuelle LTS)
+composer create-project laravel/laravel Veranstaltungen-APP
+
+cd Veranstaltungen-APP
+```
+
+### 2. Diese Dateien in das Projekt kopieren
+
+```bash
+# Kopiere alle PHP/Migration-Dateien aus diesem Package
+# in die entsprechenden Verzeichnisse
+
+# Beispiel:
+cp app/Models/*.php ./app/Models/
+cp app/Http/Controllers/*.php ./app/Http/Controllers/
+cp app/Jobs/*.php ./app/Jobs/
+cp app/Commands/*.php ./app/Commands/
+cp app/Services/*.php ./app/Services/
+cp database/migrations/*.php ./database/migrations/
+cp routes/api.php ./routes/
+```
+
+### 3. Umgebungsvariablen konfigurieren
+
+```bash
+# .env erstellen
+cp .env.example .env
+
+# Schüssel generieren
+php artisan key:generate
+```
+
+Bearbeite `.env`:
+```env
+DB_CONNECTION=mysql
+DB_HOST=127.0.0.1
+DB_PORT=3306
+DB_DATABASE=veranstaltungen_app
+DB_USERNAME=root
+DB_PASSWORD=
+
+QUEUE_CONNECTION=database
+MAIL_FROM_ADDRESS=noreply@veranstaltungen-app.de
+```
+
+### 4. Datenbank & Migrations
+
+```bash
+# Datenbank erstellen (MariaDB)
+mysql -u root -p -e "CREATE DATABASE veranstaltungen_app CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;"
+
+# Migrations ausführen
+php artisan migrate
+
+# Optionale Fixtures/Seeds laden
+php artisan db:seed --class=SourceSeeder
+```
+
+### 5. Queue für Imports vorbereiten
+
+```bash
+# Queue-Tabelle erstellen
+php artisan queue:table
+php artisan migrate
+
+# Queue Worker starten (Development)
+php artisan queue:work --verbose
+```
+
+---
+
+## 🚀 Erste Schritte
+
+### Event-Quellen erstellen
+
+```bash
+# Interaktiv via Artisan Tinker
+php artisan tinker
+
+>>> $source = \App\Models\Source::create([
+...     'name' => 'Stadt Dresden',
+...     'description' => 'Offizielle Veranstaltungen der Stadt',
+...     'url' => 'https://stadt-dresden.de',
+...     'status' => 'active',
+... ]);
+```
+
+### Events importieren
+
+```bash
+# Manueller Import (blockierend)
+php artisan events:import --sync
+
+# Oder asynchron in Queue
+php artisan events:import
+
+# Queue Worker muss laufen für Verarbeitung:
+php artisan queue:work
+```
+
+### API testen
+
+```bash
+# Events auflisten
+curl "http://localhost:8000/api/events?from=2026-04-15&to=2026-05-31&limit=10"
+
+# Ein Event anzeigen
+curl "http://localhost:8000/api/events/1"
+
+# Verfügbare Kategorien
+curl "http://localhost:8000/api/events/categories/list"
+
+# Verfügbare Orte
+curl "http://localhost:8000/api/events/locations/list"
+```
+

+```
+
+---
+
+## 🎯 Datenmodell
+
+### Events (Veranstaltungen)
+- `id` - Eindeutige ID
+- `source_id` - Referenz zur Quelle
+- `external_id` - ID der Quelle
+- `title` - Name der Veranstaltung
+- `description` - Beschreibung
+- `location` - Ort/Stadt
+- `category` - Kategorie (z.B. Kultur, Sport)
+- `slug` - URL-freundlicher Name
+- `image_url`, `website_url`, `contact_email`, `contact_phone`
+- `status` - draft | published | archived
+- `created_at`, `updated_at`
+
+### Event Occurrences (Termine)
+- `id` - Eindeutige ID
+- `event_id` - Referenz zum Event
+- `start_datetime` - Startzeit
+- `end_datetime` - Endzeit
+- `is_all_day` - Ganztägig?
+- `location_details` - Raum/Gebäude
+- `capacity` - Kapazität
+- `available_tickets` - Verfügbare Tickets
+- `price` - Preis (optional)
+- `status` - scheduled | cancelled | completed
+
+### Sources (Quellen)
+- `id` - Eindeutige ID
+- `name` - Name der Quelle
+- `description` - Beschreibung
+- `url` - Website URL
+- `status` - active | inactive
+- `last_import_at` - Letzter Import-Zeitpunkt
+
+---
+
+## 🔄 Import-Workflow
+
+```
+1. External Source (z.B. Stadt Dresden API)
+   ↓
+2. ImportEventsCommand / EventImportService
+   ↓
+3. ImportEventsJob (läuft in Queue)
+   ↓
+4. fetchExternalEvents() - Ruft externe Daten ab
+   ↓
+5. upsertEvent() - Erstellt oder aktualisiert Event+Occurrences
+   ↓
+6. Database (MySQL/MariaDB)
+   ↓
+7. API (für Frontend verfügbar)
+```
+
+### Upsert-Logik
+- Events werden anhand `[source_id, external_id]` abgeglichen
+- Existierende Events = Update
+- Neue Events = Insert
+- Verhindert Duplikate durch Unique Index
+
+---
+
+## ⏰ Geplante Imports (Scheduler)
+
+In `app/Console/Kernel.php` (siehe Beispiel):
+
+- **03:00 Uhr** - Täglich alle Quellen importieren
+- **Stündlich** - Stadt-Dresden-Quelle (häufige Updates)
+- **Alle 6 Stunden** - Andere Quellen
+- **04:00 Uhr** - Markiere abgelaufene Termine
+- **Sonntag 05:00** - Räume archivierte Events auf
+
+---
+
+## 🛠️ Commands
+
+```bash
+# Event-Import
+php artisan events:import [--source=ID|Name] [--sync]
+
+# Queue einrichten
+php artisan queue:table
+php artisan migrate
+
+# Queue Worker starten (Development)
+php artisan queue:work [--verbose] [--tries=3] [--timeout=120]
+
+# Failed Jobs anzeigen
+php artisan queue:failed
+php artisan queue:retry ID
+php artisan queue:forget ID
+
+# Alle Jobs leeren
+php artisan queue:flush
+
+# Cache leeren
+php artisan cache:clear
+
+# Logs leeren
+php artisan log:prune
+
+# Datenbank frisch seeden
+php artisan migrate:refresh --seed
+```
+
+---
+
+## 📊 Datenbank-Indizes
+
+Die Migrationen erstellen folgende Indizes für Performance:
+
+**sources:**
+- `status` (Filter nach aktiv/inaktiv)
+- `created_at` (Sortierer)
+
+**events:**
+- `source_id` (Foreign Key)
+- `slug` (Unique, für SEO-URLs)
+- `[location, status]` (Composite Index für Location-Filter)
+- `[category, status]` (Composite Index für Kategorie-Filter)
+- `created_at` (Neueste zuerst)
+- `[source_id, external_id]` (Unique, verhindert Duplikate)
+
+**event_occurrences:**
+- `event_id` (Foreign Key)
+- `start_datetime` (Filter nach Datum)
+- `[start_datetime, status]` (Composite Index für "nächste Events")
+- `[event_id, status]` (Filter nach Event & Status)
+
+---
+
+## 🔐 Security-Best-Practices
+
+✅ **Implementiert:**
+- SQL-Injections vermieden (Eloquent ORM)
+- CSRF-Schutz (Laravel Standard)
+- Rate Limiting für APIs
+- Input Validation in Controllers
+- Soft Deletes für Datenintegrität
+
+⚠️ **Zu implementieren:**
+- API-Authentifizierung (Laravel Passport/Sanctum)
+- Request Throttling
+- CORS-Konfiguration
+- Content Security Policy
+
+---
+
+## 🐛 Troubleshooting
+
+### Migrations schlagen fehl
+```bash
+# Checke MariaDB Version
+mysql --version
+
+# Migrations zurückrollen
+php artisan migrate:reset
+
+# Neu starten
+php artisan migrate
+```
+
+### Queue-Jobs werden nicht verarbeitet
+```bash
+# Worker-Prozess läuft?
+ps aux | grep "queue:work"
+
+# Queue starten (Development)
+php artisan queue:work --verbose
+```
+
+### API gibt 404 zurück
+```bash
+# Checke Routes
+php artisan route:list
+
+# Starte Server
+php artisan serve
+```
+
+### Zu viel Memory-Verbrauch
+```bash
+# Optimize Autoloader
+composer install --optimize-autoloader --no-dev
+
+# Disable Query Logging in Production
+# In .env: APP_DEBUG=false
+```
+
+---
+
+## 📈 Production Deployment
+
+### Vorbereitung
+```bash
+# .env für Production
+APP_ENV=production
+APP_DEBUG=false
+QUEUE_CONNECTION=redis  # oder beanstalkd
+LOG_CHANNEL=stack
+```
+
+### Cron-Job einrichten (Scheduler)
+```bash
+# /etc/cron.d/laravel-scheduler
+* * * * * cd /path/to/app && php artisan schedule:run >> /dev/null 2>&1
+```
+
+Oder mit systemd:
+```bash
+# supervisor für Queue Workers
+[program:laravel-worker]
+process_name=%(program_name)s_%(process_num)02d
+command=php /path/to/app/artisan queue:work redis --sleep=3 --tries=3 --timeout=90
+autostart=true
+autorestart=true
+numprocs=4
+redirect_stderr=true
+stdout_logfile=/path/to/app/storage/logs/worker.log
+```
+
+---
+
+## 🤝 Weitere Integration
+
+### Beispiel: Import aus Stadt-Dresden-API
+
+Bearbeite `app/Jobs/ImportEventsJob.php`:
+
+```php
+protected function fetchExternalEvents()
+{
+    $response = Http::withHeaders([
+        'Accept' => 'application/json',
+    ])->get('https://api.stadt-dresden.de/events', [
+        'limit' => 1000,
+    ]);
+
+    return $response->json('data');
+}
+```
+
+### Beispiel: Web-Scraping
+
+```bash
+composer require symfony/dom-crawler symfony/http-client
+```
+
+Dann in Import-Service:
+```php
+use Symfony\Component\DomCrawler\Crawler;
+
+$response = Http::get('https://example.com/events');
+$crawler = new Crawler($response->body());
+// ... scrape & extract events
+```

+
+## [0.13.1](https://github.com/brick/math/releases/tag/0.13.1) - 2025-03-29
+
+✨ **Improvements**
+
+- `__toString()` methods of `BigInteger` and `BigDecimal` are now type-hinted as returning `numeric-string` instead of `string` (#90 by @vudaltsov)

+
+## [0.12.2](https://github.com/brick/math/releases/tag/0.12.2) - 2025-02-26
+
+⚡️ **Performance improvements**
+
+- Division in `NativeCalculator` is now faster for small divisors, thanks to [@Izumi-kun](https://github.com/Izumi-kun) in [#87](https://github.com/brick/math/pull/87).
+
+👌 **Improvements**
+
+- Add missing `RoundingNecessaryException` to the `@throws` annotation of `BigNumber::of()`
+
+## [0.12.1](https://github.com/brick/math/releases/tag/0.12.1) - 2023-11-29
+
+⚡️ **Performance improvements**
+
+- `BigNumber::of()` is now faster, thanks to [@SebastienDug](https://github.com/SebastienDug) in [#77](https://github.com/brick/math/pull/77).
+
+## [0.12.0](https://github.com/brick/math/releases/tag/0.12.0) - 2023-11-26
+
+💥 **Breaking changes**
+
+- Minimum PHP version is now 8.1
+- `RoundingMode` is now an `enum`; if you're type-hinting rounding modes, you need to type-hint against `RoundingMode` instead of `int` now
+- `BigNumber` classes do not implement the `Serializable` interface anymore (they use the [new custom object serialization mechanism](https://wiki.php.net/rfc/custom_object_serialization))
+- The following breaking changes only affect you if you're creating your own `BigNumber` subclasses:
+  - the return type of `BigNumber::of()` is now `static`
+  - `BigNumber` has a new abstract method `from()`
+  - all `public` and `protected` functions of `BigNumber` are now `final`
+
+## [0.11.0](https://github.com/brick/math/releases/tag/0.11.0) - 2023-01-16
+
+💥 **Breaking changes**
+
+- Minimum PHP version is now 8.0
+- Methods accepting a union of types are now strongly typed<sup>*</sup>
+- `MathException` now extends `Exception` instead of `RuntimeException`
+
+<sup>* You may now run into type errors if you were passing `Stringable` objects to `of()` or any of the methods
+internally calling `of()`, with `strict_types` enabled. You can fix this by casting `Stringable` objects to `string`
+first.</sup>
+
+## [0.10.2](https://github.com/brick/math/releases/tag/0.10.2) - 2022-08-11
+
+👌 **Improvements**
+
+- `BigRational::toFloat()` now simplifies the fraction before performing division (#73) thanks to @olsavmic
+
+## [0.10.1](https://github.com/brick/math/releases/tag/0.10.1) - 2022-08-02
+
+✨ **New features**
+
+- `BigInteger::gcdMultiple()` returns the GCD of multiple `BigInteger` numbers
+
+## [0.10.0](https://github.com/brick/math/releases/tag/0.10.0) - 2022-06-18
+
+💥 **Breaking changes**
+
+- Minimum PHP version is now 7.4
+
+## [0.9.3](https://github.com/brick/math/releases/tag/0.9.3) - 2021-08-15
+
+🚀 **Compatibility with PHP 8.1**
+
+- Support for custom object serialization; this removes a warning on PHP 8.1 due to the `Serializable` interface being deprecated (#60) thanks @TRowbotham
+
+## [0.9.2](https://github.com/brick/math/releases/tag/0.9.2) - 2021-01-20
+
+🐛 **Bug fix**
+
+- Incorrect results could be returned when using the BCMath calculator, with a default scale set with `bcscale()`, on PHP >= 7.2 (#55).
+
+## [0.9.1](https://github.com/brick/math/releases/tag/0.9.1) - 2020-08-19
+
+✨ **New features**
+
+- `BigInteger::not()` returns the bitwise `NOT` value
+
+🐛 **Bug fixes**
+
+- `BigInteger::toBytes()` could return an incorrect binary representation for some numbers
+- The bitwise operations `and()`, `or()`, `xor()` on `BigInteger` could return an incorrect result when the GMP extension is not available
+
+## [0.9.0](https://github.com/brick/math/releases/tag/0.9.0) - 2020-08-18
+
+👌 **Improvements**
+
+- `BigNumber::of()` now accepts `.123` and `123.` formats, both of which return a `BigDecimal`
+
+💥 **Breaking changes**
+
+- Deprecated method `BigInteger::powerMod()` has been removed - use `modPow()` instead
+- Deprecated method `BigInteger::parse()` has been removed - use `fromBase()` instead
+
+## [0.8.17](https://github.com/brick/math/releases/tag/0.8.17) - 2020-08-19
+
+🐛 **Bug fix**
+
+- `BigInteger::toBytes()` could return an incorrect binary representation for some numbers
+- The bitwise operations `and()`, `or()`, `xor()` on `BigInteger` could return an incorrect result when the GMP extension is not available
+
+## [0.8.16](https://github.com/brick/math/releases/tag/0.8.16) - 2020-08-18
+
+🚑 **Critical fix**
+
+- This version reintroduces the deprecated `BigInteger::parse()` method, that has been removed by mistake in version `0.8.9` and should have lasted for the whole `0.8` release cycle.
+
+✨ **New features**
+
+- `BigInteger::modInverse()` calculates a modular multiplicative inverse
+- `BigInteger::fromBytes()` creates a `BigInteger` from a byte string
+- `BigInteger::toBytes()` converts a `BigInteger` to a byte string
+- `BigInteger::randomBits()` creates a pseudo-random `BigInteger` of a given bit length
+- `BigInteger::randomRange()` creates a pseudo-random `BigInteger` between two bounds
+
+💩 **Deprecations**
+
+- `BigInteger::powerMod()` is now deprecated in favour of `modPow()`
+
+## [0.8.15](https://github.com/brick/math/releases/tag/0.8.15) - 2020-04-15
+
+🐛 **Fixes**
+
+- added missing `ext-json` requirement, due to `BigNumber` implementing `JsonSerializable`
+
+⚡️ **Optimizations**
+
+- additional optimization in `BigInteger::remainder()`
+
+## [0.8.14](https://github.com/brick/math/releases/tag/0.8.14) - 2020-02-18
+
+✨ **New features**
+
+- `BigInteger::getLowestSetBit()` returns the index of the rightmost one bit
+
+## [0.8.13](https://github.com/brick/math/releases/tag/0.8.13) - 2020-02-16
+
+✨ **New features**
+
+- `BigInteger::isEven()` tests whether the number is even
+- `BigInteger::isOdd()` tests whether the number is odd
+- `BigInteger::testBit()` tests if a bit is set
+- `BigInteger::getBitLength()` returns the number of bits in the minimal representation of the number
+
+## [0.8.12](https://github.com/brick/math/releases/tag/0.8.12) - 2020-02-03
+
+🛠️ **Maintenance release**
+
+Classes are now annotated for better static analysis with [psalm](https://psalm.dev/).
+
+This is a maintenance release: no bug fixes, no new features, no breaking changes.
+
+## [0.8.11](https://github.com/brick/math/releases/tag/0.8.11) - 2020-01-23
+
+✨ **New feature**
+
+`BigInteger::powerMod()` performs a power-with-modulo operation. Useful for crypto.
+
+## [0.8.10](https://github.com/brick/math/releases/tag/0.8.10) - 2020-01-21
+
+✨ **New feature**
+
+`BigInteger::mod()` returns the **modulo** of two numbers. The *modulo* differs from the *remainder* when the signs of the operands are different.
+
+## [0.8.9](https://github.com/brick/math/releases/tag/0.8.9) - 2020-01-08
+
+⚡️ **Performance improvements**
+
+A few additional optimizations in `BigInteger` and `BigDecimal` when one of the operands can be returned as is. Thanks to @tomtomsen in #24.
+
+## [0.8.8](https://github.com/brick/math/releases/tag/0.8.8) - 2019-04-25
+
+🐛 **Bug fixes**
+
+- `BigInteger::toBase()` could return an empty string for zero values (BCMath & Native calculators only, GMP calculator unaffected)
+
+✨ **New features**
+
+- `BigInteger::toArbitraryBase()` converts a number to an arbitrary base, using a custom alphabet
+- `BigInteger::fromArbitraryBase()` converts a string in an arbitrary base, using a custom alphabet, back to a number
+
+These methods can be used as the foundation to convert strings between different bases/alphabets, using BigInteger as an intermediate representation.
+
+💩 **Deprecations**
+
+- `BigInteger::parse()` is now deprecated in favour of `fromBase()`
+
+`BigInteger::fromBase()` works the same way as `parse()`, with 2 minor differences:
+
+- the `$base` parameter is required, it does not default to `10`
+- it throws a `NumberFormatException` instead of an `InvalidArgumentException` when the number is malformed
+
+## [0.8.7](https://github.com/brick/math/releases/tag/0.8.7) - 2019-04-20
+
+**Improvements**
+
+- Safer conversion from `float` when using custom locales
+- **Much faster** `NativeCalculator` implementation 🚀
+
+You can expect **at least a 3x performance improvement** for common arithmetic operations when using the library on systems without GMP or BCMath; it gets exponentially faster on multiplications with a high number of digits. This is due to calculations now being performed on whole blocks of digits (the block size depending on the platform, 32-bit or 64-bit) instead of digit-by-digit as before.
+
+## [0.8.6](https://github.com/brick/math/releases/tag/0.8.6) - 2019-04-11
+
+**New method**
+
+`BigNumber::sum()` returns the sum of one or more numbers.
+
+## [0.8.5](https://github.com/brick/math/releases/tag/0.8.5) - 2019-02-12
+
+**Bug fix**: `of()` factory methods could fail when passing a `float` in environments using a `LC_NUMERIC` locale with a decimal separator other than `'.'` (#20).
+
+Thanks @manowark 👍
+
+## [0.8.4](https://github.com/brick/math/releases/tag/0.8.4) - 2018-12-07
+
+**New method**
+
+`BigDecimal::sqrt()` calculates the square root of a decimal number, to a given scale.
+
+## [0.8.3](https://github.com/brick/math/releases/tag/0.8.3) - 2018-12-06
+
+**New method**
+
+`BigInteger::sqrt()` calculates the square root of a number (thanks @peter279k).
+
+**New exception**
+
+`NegativeNumberException` is thrown when calling `sqrt()` on a negative number.
+
+## [0.8.2](https://github.com/brick/math/releases/tag/0.8.2) - 2018-11-08
+
+**Performance update**
+
+- Further improvement of `toInt()` performance
+- `NativeCalculator` can now perform some multiplications more efficiently
+
+## [0.8.1](https://github.com/brick/math/releases/tag/0.8.1) - 2018-11-07
+
+Performance optimization of `toInt()` methods.
+
+## [0.8.0](https://github.com/brick/math/releases/tag/0.8.0) - 2018-10-13
+
+**Breaking changes**
+
+The following deprecated methods have been removed. Use the new method name instead:
+
+| Method removed | Replacement method |
+| --- | --- |
+| `BigDecimal::getIntegral()` | `BigDecimal::getIntegralPart()` |
+| `BigDecimal::getFraction()` | `BigDecimal::getFractionalPart()` |
+
+---
+
+**New features**
+
+`BigInteger` has been augmented with 5 new methods for bitwise operations:
+
+| New method | Description |
+| --- | --- |
+| `and()` | performs a bitwise `AND` operation on two numbers |
+| `or()` | performs a bitwise `OR` operation on two numbers |
+| `xor()` | performs a bitwise `XOR` operation on two numbers |
+| `shiftedLeft()` | returns the number shifted left by a number of bits |
+| `shiftedRight()` | returns the number shifted right by a number of bits |
+
+Thanks to @DASPRiD 👍
+
+## [0.7.3](https://github.com/brick/math/releases/tag/0.7.3) - 2018-08-20
+
+**New method:** `BigDecimal::hasNonZeroFractionalPart()`
+
+**Renamed/deprecated methods:**
+
+- `BigDecimal::getIntegral()` has been renamed to `getIntegralPart()` and is now deprecated

+
+## [0.7.2](https://github.com/brick/math/releases/tag/0.7.2) - 2018-07-21
+
+**Performance update**
+
+`BigInteger::parse()` and `toBase()` now use GMP's built-in base conversion features when available.
+
+## [0.7.1](https://github.com/brick/math/releases/tag/0.7.1) - 2018-03-01
+
+This is a maintenance release, no code has been changed.
+
+- When installed with `--no-dev`, the autoloader does not autoload tests anymore
+- Tests and other files unnecessary for production are excluded from the dist package
+
+This will help make installations more compact.
+
+## [0.7.0](https://github.com/brick/math/releases/tag/0.7.0) - 2017-10-02
+
+Methods renamed:
+

+
+## [0.6.2](https://github.com/brick/math/releases/tag/0.6.2) - 2017-10-02
+
+The base class for all exceptions is now `MathException`.
+`ArithmeticException` has been deprecated, and will be removed in 0.7.0.
+
+## [0.6.1](https://github.com/brick/math/releases/tag/0.6.1) - 2017-10-02
+
+A number of methods have been renamed:
+
+- `BigNumber:sign()` is deprecated; use `getSign()` instead
+- `BigDecimal::unscaledValue()` is deprecated; use `getUnscaledValue()` instead
+- `BigDecimal::scale()` is deprecated; use `getScale()` instead
+- `BigDecimal::integral()` is deprecated; use `getIntegral()` instead
+- `BigDecimal::fraction()` is deprecated; use `getFraction()` instead
+- `BigRational::numerator()` is deprecated; use `getNumerator()` instead
+- `BigRational::denominator()` is deprecated; use `getDenominator()` instead
+
+The old methods will be removed in version 0.7.0.
+
+## [0.6.0](https://github.com/brick/math/releases/tag/0.6.0) - 2017-08-25
+
+- Minimum PHP version is now [7.1](https://gophp71.org/); for PHP 5.6 and PHP 7.0 support, use version `0.5`
+- Deprecated method `BigDecimal::withScale()` has been removed; use `toScale()` instead
+- Method `BigNumber::toInteger()` has been renamed to `toInt()`
+
+## [0.5.4](https://github.com/brick/math/releases/tag/0.5.4) - 2016-10-17
+
+`BigNumber` classes now implement [JsonSerializable](http://php.net/manual/en/class.jsonserializable.php).
+The JSON output is always a string.
+
+## [0.5.3](https://github.com/brick/math/releases/tag/0.5.3) - 2016-03-31
+
+This is a bugfix release. Dividing by a negative power of 1 with the same scale as the dividend could trigger an incorrect optimization which resulted in a wrong result. See #6.
+
+## [0.5.2](https://github.com/brick/math/releases/tag/0.5.2) - 2015-08-06
+
+The `$scale` parameter of `BigDecimal::dividedBy()` is now optional again.
+
+## [0.5.1](https://github.com/brick/math/releases/tag/0.5.1) - 2015-07-05
+
+**New method: `BigNumber::toScale()`**
+
+This allows to convert any `BigNumber` to a `BigDecimal` with a given scale, using rounding if necessary.
+
+## [0.5.0](https://github.com/brick/math/releases/tag/0.5.0) - 2015-07-04
+
+**New features**
+- Common `BigNumber` interface for all classes, with the following methods:
+  - `sign()` and derived methods (`isZero()`, `isPositive()`, ...)
+  - `compareTo()` and derived methods (`isEqualTo()`, `isGreaterThan()`, ...) that work across different `BigNumber` types
+  - `toBigInteger()`, `toBigDecimal()`, `toBigRational`() conversion methods
+  - `toInteger()` and `toFloat()` conversion methods to native types
+- Unified `of()` behaviour: every class now accepts any type of number, provided that it can be safely converted to the current type
+- New method: `BigDecimal::exactlyDividedBy()`; this method automatically computes the scale of the result, provided that the division yields a finite number of digits
+- New methods: `BigRational::quotient()` and `remainder()`
+- Fine-grained exceptions: `DivisionByZeroException`, `RoundingNecessaryException`, `NumberFormatException`
+- Factory methods `zero()`, `one()` and `ten()` available in all classes
+- Rounding mode reintroduced in `BigInteger::dividedBy()`
+
+This release also comes with many performance improvements.
+
+---
+
+**Breaking changes**
+- `BigInteger`:
+  - `getSign()` is renamed to `sign()`
+  - `toString()` is renamed to `toBase()`
+  - `BigInteger::dividedBy()` now throws an exception by default if the remainder is not zero; use `quotient()` to get the previous behaviour
+- `BigDecimal`:
+  - `getSign()` is renamed to `sign()`
+  - `getUnscaledValue()` is renamed to `unscaledValue()`
+  - `getScale()` is renamed to `scale()`
+  - `getIntegral()` is renamed to `integral()`
+  - `getFraction()` is renamed to `fraction()`
+  - `divideAndRemainder()` is renamed to `quotientAndRemainder()`
+  - `dividedBy()` now takes a **mandatory** `$scale` parameter **before** the rounding mode
+  - `toBigInteger()` does not accept a `$roundingMode` parameter anymore
+  - `toBigRational()` does not simplify the fraction anymore; explicitly add `->simplified()` to get the previous behaviour
+- `BigRational`:
+  - `getSign()` is renamed to `sign()`
+  - `getNumerator()` is renamed to  `numerator()`
+  - `getDenominator()` is renamed to  `denominator()`
+  - `of()` is renamed to `nd()`, while `parse()` is renamed to `of()`
+- Miscellaneous:
+  - `ArithmeticException` is moved to an `Exception\` sub-namespace
+  - `of()` factory methods now throw `NumberFormatException` instead of `InvalidArgumentException`
+
+## [0.4.3](https://github.com/brick/math/releases/tag/0.4.3) - 2016-03-31
+
+Backport of two bug fixes from the 0.5 branch:
+- `BigInteger::parse()` did not always throw `InvalidArgumentException` as expected
+- Dividing by a negative power of 1 with the same scale as the dividend could trigger an incorrect optimization which resulted in a wrong result. See #6.
+
+## [0.4.2](https://github.com/brick/math/releases/tag/0.4.2) - 2015-06-16
+
+New method: `BigDecimal::stripTrailingZeros()`
+
+## [0.4.1](https://github.com/brick/math/releases/tag/0.4.1) - 2015-06-12
+
+Introducing a `BigRational` class, to perform calculations on fractions of any size.
+
+## [0.4.0](https://github.com/brick/math/releases/tag/0.4.0) - 2015-06-12
+
+Rounding modes have been removed from `BigInteger`, and are now a concept specific to `BigDecimal`.
+
+`BigInteger::dividedBy()` now always returns the quotient of the division.
+
+## [0.3.5](https://github.com/brick/math/releases/tag/0.3.5) - 2016-03-31
+
+Backport of two bug fixes from the 0.5 branch:
+
+- `BigInteger::parse()` did not always throw `InvalidArgumentException` as expected
+- Dividing by a negative power of 1 with the same scale as the dividend could trigger an incorrect optimization which resulted in a wrong result. See #6.
+
+## [0.3.4](https://github.com/brick/math/releases/tag/0.3.4) - 2015-06-11
+
+New methods:
+- `BigInteger::remainder()` returns the remainder of a division only
+- `BigInteger::gcd()` returns the greatest common divisor of two numbers
+
+## [0.3.3](https://github.com/brick/math/releases/tag/0.3.3) - 2015-06-07
+
+Fix `toString()` not handling negative numbers.
+
+## [0.3.2](https://github.com/brick/math/releases/tag/0.3.2) - 2015-06-07
+
+`BigInteger` and `BigDecimal` now have a `getSign()` method that returns:
+- `-1` if the number is negative
+- `0` if the number is zero
+- `1` if the number is positive
+
+## [0.3.1](https://github.com/brick/math/releases/tag/0.3.1) - 2015-06-05
+
+Minor performance improvements
+
+## [0.3.0](https://github.com/brick/math/releases/tag/0.3.0) - 2015-06-04

+
+## [0.2.2](https://github.com/brick/math/releases/tag/0.2.2) - 2015-06-04
+
+Stronger immutability guarantee for `BigInteger` and `BigDecimal`.
+
+So far, it would have been possible to break immutability of these classes by calling the `unserialize()` internal function. This release fixes that.
+
+## [0.2.1](https://github.com/brick/math/releases/tag/0.2.1) - 2015-06-02
+
+Added `BigDecimal::divideAndRemainder()`
+
+## [0.2.0](https://github.com/brick/math/releases/tag/0.2.0) - 2015-05-22
