Here are some of the changes worth exploring in more detail - or just a different way of slicing the changelog:

• Wayland server backend: wayland server backend #387, finally - (already much improved in v6.6)
• Record and replay sessions: session recording client #4812
• faster startup: asynchronous feature initialization #4557 (still somewhat gated for backwards compatibility)
• macOS notarizing #2441 will lead to having notarized downloads, and potentially having them available in the macos appstore
• the MS Windows native opengl client (native win32 opengl client #921) will be improved in the next release with better DPI support and performance enhancements - it may become the new default
• the SSL issues that have caused us so much pain lately should finally be over: SSL connection handshake fails, sometimes #4660
• authentication improvements of all sorts - with more to come: per authentication module options #3791, make it easier to override http error pages #4732, add http headers to exec authentication modules #4755
• prettier opengl rendering OpenGL: Catmull-Rom bicubic scaling shader #4819 / Add sigmoid upscaling and anti-ringing to OpenGL upscale shader #4826
• we can process our picture buffers with AI: make it easier to implement image filters using pytorch #4776
• diagnostics: improve network diagnostics documentation #4740, memory diagnostics #4880, create a wireshark dissector #1188, document subsystems and protocol layer #3981
