OpenBSD 4.7

[arjanhs]

Woensdag is de nieuwe halfjaarlijkse release van OpenBSD uitgekomen. Op deze pagina is een uitgebreide lijst van ftp- en http-downloadlocaties te vinden. OpenBSD stamt van de originele Berkeley Software Distribution af en staat erom bekend dat de ontwikkelaars alleen opensource-software willen gebruiken. Verder staat het OS bekend om zijn uitstekende documentatie en veiligheid. Zoals gewoonlijk met een nieuwe versie van OpenBSD is er ook een nieuw thema ontworpen rondom het OS, vergezeld van een heuse theme song en verkrijgbaar op audio-cd, als poster en als T-shirt. Als titel van het thema heeft men deze keer gekozen voor 'I'm still here'. Hieronder is een gedetailleerd overzicht van de doorgevoerde veranderingen in versie 4.7 te vinden.
