Lots of people have asked for an installer that also sets up Python and all other basic components so they can get started quickly. Because of this I have now created a PowerShell script that will set up a complete portable environment. Just grab Install-Portable-VapourSynth-R*.ps1 from the release and run it. Everything will be installed into the current directory. It will probably be expanded upon further in the next release and install even more things so feel free to suggest the additional things you want. Maybe an optional editor or the option to directly install the most common plugins and scripts. Or even optional VFW integration?

Now to the small things. Python 3.12.x is now required. Several rare memory leaks and crashes were fixed. There’s a new graph output mode in vspipe that also includes filter times. Audio headers in VFW have been improved so normal DirectShow media players can be used for audio preview.
