Versie 5.0.1 van WordPress is uitgekomen. Met dit programma, dat onder een gpl beschikbaar wordt gesteld, is het mogelijk om een website of blog op te zetten en bij te houden. WordPress is eenvoudig in te stellen en kan binnen vijf minuten draaien mits er al een server met php en MySQL beschikbaar is. Er zijn mogelijkheden om de functionaliteit van WordPress verder uit te breiden met plug-ins en het uiterlijk met thema's aan te passen.
Versie 5.0 bevat onder meer een compleet vernieuwde editor en een nieuw standaard thema. De oude editor is ook nog steeds aanwezig en draagt nu de naam classic editor. De release notes voor deze uitgave kunnen hieronder worden gevonden. In deze update zijn diverse beveiligingsproblemen verholpen.
