What's new in B7

- [D12] Implemented indirectCopy mode for GPUs (Radeon) that fault when DMA is used to write directly to IVSHMEM (slower, but still faster then the DXGI backend). - [Windows] User switching should no longer cause a crash - [Windows] Logs are now rotated and the service log has been moved to prevent the wrong log being used in error reports - [client] Added .desktop file which is properly installed with make install now. - [module] Fixed compatibillity with 6.13+ kernels - [obs] Fixed outstanding bug with DMABUF that resulted in only using half the frames - [host] Fixed re-initialization race issue when the guest is suspended and resumed - [doc] Encourage usage of KVMFR/DMABUF as the standard now - [client] Fixed a race condition when showing overlay messages which would result in a crash
