Message:

• Upraveno: Použita novější databázová třída Database, která běží přes PDO.
• Přidáno: Pokud databáze nesouhlasí k verzi systému, je zobrazeno chybové hlášení.
• Přidáno: Instalační skript admin/install.php, přes který je možno nainstalovat čistou databázi a provádět automatickou aktualizaci databáze.
• Upraveno: Konkrétní rozdílové SQL aktualizace jsou nyní zapsány přímo v kódu v souboru UpdateTrace namísto textových SQL skriptů. To umožňuje provádět také dynamickou aktualizaci dle obsahu dat v tabulkách. Zde pro získání seznamu překladových tabulek.
• Opraveno: Některé části kódu nepodporovaly nulový počet překladových skupin nebo jazyků.
