Release Notes: This is mainly a bugfix release for PipesFS, which proved to have many (even shameful) bugs in its first release. All known issues but one have been resolved. Unrelated new features include the mpipe() call for multi-consumer pipes, an interface to directly manipulate active filters, and an expanded automated test set to minimize future regressions.
Release Notes: A critical bug in the installation process has been fixed.
Release Notes: This release was the basis for real application benchmarks (BIND and Mplayer) and thus has been thoroughly tested. New features include a Sockets interface for UDP applications, a driver interface with the Intel Pro/1000 example device, and x86_64 and multithreading support. More important are the numerous bugfixes and minor interface cleanups.
Release Notes: This is mostly a bugfix release. The most serious bugs that were squashed are those resulting from concurrent access to the kernel, and a remapping issue that kept giving the same page from kernelspace to userspace. New features are autoconfiguration of 3rd party library support (Tcl, pcap, and readline) and pcap backend support. The latter has been tested to work with tcpdump.
