"DragonFly version 6.0 is the next step from the 5.8 release series in 2020. This version has a revamped VFS caching system, various filesystem updates including HAMMER2, and a long list of userland updates. The details of all commits between the 5.8 and 6.0 branches are available in the associated commit messages for 6.0.0rc1 and 6.0.0. Big-ticket items: Significant work on dsynth, for building packages. Many updates of contrib system software. HAMMER2 work continues, with updates from Tomohiro Kusumi. Major VM work for extent-based representation. Due to major changes to the VM system we had to remove the MAP_VPAGETABLE mmap() feature, and this also means that vkernels will not be supported in this release. Support may be re-added at a later time via HVM (but not in this release)."

The DragonFly BSD team has published a new release, version 5.8.0 of the server-oriented operating system. The new version makes it easier for users to compile their own repository of binary packages from ports, addresses some glitches in low-memory situations and improves video driver support. "Big-ticket items: dsynth(1) written and added to base, making it more convenient for users to build their own binary repos for DPorts(7). dsynth is used to build some or all of the DPorts collection, over 25000 third-party packages. It's also working as an informal performance measure, with many of the changes in this release to speed up DragonFly when building multiple dependent packages. Many ports these days seem to assume a greater degree of signal safety for libc function, particularly for malloc(). We have implemented a low-overhead signal masking feature that now allows us to make malloc*() and other related functions signal-safe. A ton of bug fixes, stability work, and usability work has gone into this release. Many niggling little annoyances, such as Chrome/Chromium stuttering when system memory is low, have been fixed. DRM (GPU) support continues to improve slowly but steadily. Significantly improved paging algorithms reduces or eliminates UI/browser glitches in low-memory situations."
