Mai kwaikwayon kwamitin 'xlnx-versal-virt' ya ƙara tallafi don PMC SLCR da OSPI Flash mai sarrafa ƙwaƙwalwar ajiya. An ƙara sabbin samfuran sarrafawa na CRF da APU don injunan kwaikwaya 'xlnx-zynqmp'. Ƙara kwaikwaya na FEAT_LVA2, FEAT_LVA (Babban Adireshin Mahimmanci) da FEAT_LPA (Babban filin Adireshin Jiki).
- The classic Tiny Code Generator (TCG) ya daina tallafawa runduna tare da ARMv4 da ARMv5 CPUs, waɗanda basu da tallafi don samun damar ƙwaƙwalwar ajiya mara daidaituwa kuma basu da isasshen RAM don gudanar da QEMU.
- RISC-V emulator na gine-gine yana ƙara tallafi ga hypervisor KVM kuma yana aiwatar da kariyar vector 1.0, da Zve64f, Zve32f, Zfhmin, Zfh, zfinx, zdinx da zhinx{min} umarni. Ƙara goyon baya don lodawa OpenSBI (RISC-V Supervisor Binary Interface) fayilolin binaryar don injunan kwaikwaya. Don injunan 'virt' da aka kwaikwayi, ana aiwatar da ikon yin amfani da har zuwa 32 na'urorin sarrafawa da tallafin AIA.
