R5 was the 4th major release of BeOS for a public audience, and the 6th since it left developer-only stages. It changed only slightly from the previous release, BeOS R4.5, and was even seeded to developers as "R4.6". Improved POSIX compliance, particularly in the area of networking, was provided. The OS in general was moved towards the new modular media kit over the former audio-only sound subsystem. For end-users, new logos and some new icons were the only major differences.
R5 was the first release of BeOS for x86 to have a freely downloadable version which could be fully installed on a user's hard drive; previous versions had a free Live CD download, which could not be installed. R5 was also to be the last version to support the PowerPC architecture with BeOS had originated on, including the companies own BeBox hardware. According to Be's marketing, it was the first OS to ship with legal MP3 encoding and decoding support.
The CD shipped with an ISO9660/HFS hybrid partition, containing documentation, GPL licenced source code, the Personal Edition installer (with the aim of you circulating the installer to friends), a copy of Partition Magic for Windows, and the Mac OS boot-loading code for the PowerPC version. Two separate BFS partitions existed, one for x86, one for PowerPC, and the x86 one is directly bootable from CD.
In addition to all the features of Personal Edition, Professional Edition includes the full developers tools, including a rebranded CodeWarrior, RealPlayer G2, Fraunhofer MP3 encoders, and support for both encoding Indeo video, and playback/encoding of Indeo Real Time. Additional media on the CD varied by supplier, but always included some sample multimedia files, including two songs composed by Be staff (" 5038" and " virtual (void)") as well as a video of Be staff pushing computer monitors off the roof of their building in Menlo Park.
]. The update, however, made a change to the core C library to do this, and in doing so, updated the version of glibc it was based on, again providing slightly more POSIX compatibility.
Another extremely widely leaked update is a new, fully POSIX compliant, kernel-land networking stack, known internally in Be as BONE. While officially alpha, this brings higher stability to R5, as well as opening up the application base available. The updater for BONE Alpha 7 increases the system version number to R5.04.
A new commercial venture, ZETA, is an operating system that appears to be based on the Dano codebase, and has been accepted by some BeOS users as a successor to R5. However, at least during its protracted release candidate stage, it was dogged with problems that have left some people using R5, and in some cases, looking to Haiku for the future of their OS.
