Solaris 2.4, the version of Solaris that derives both iAPX-86 and Sparc versions from the same source tree – and from which the IBM Corp PowerPC version will be derived – is on schedule for release this August, according to Janpieter Scheerder, vice-president and general manager, Solaris product division. Scheerder told attendees at the UK Sunsoft developers conference that Sun Microsystems Inc had learned from the traumatic transition to Solaris 2.3, and that the new release would not come out until he was convinced it was ready. We’re viewing every program violation as a showstopper, he said.
