Today is a TechPresentations day – I published two presentations about Google infrastructure systems (an overview and BigTable) and one about Ubuntu Linix by its founder, Mark Shuttleworth who sold Thawte to Verisign and became second space tourist (I thought he was first).

I fixed annoying bug in XML::RSS::LibXML which rendered multiple tags as one tag with value of ARRAY(…).

It was most often seen when multiple categories were assigned to feed item but affected all duplicate tags (I fixed similar problem specifically with enclosures earlier).

Hope that will not break feeds any more.
