"DragonFly version 5.2 brings Meltdown/Spectre mitigation, significant improvements to HAMMER2, ipfw, and graphics acceleration.... Big-ticket items: Meltdown and Spectre mitigation support; Meltdown isolation and Spectre mitigation support added. Meltdown mitigation is automatically enabled for all Intel CPUs. Spectre mitigation must be enabled manually via sysctl if desired, using sysctls machdep.spectre_mitigation and machdep.meltdown_mitigation. HAMMER2 - H2 has received a very large number of bug fixes and performance improvements. We can now recommend H2 as the default root file system in non-clustered mode. Clustered support is not yet available."
