• Upgraded to .NET 5.0. This was a big, disruptive upgrade that marks the end of the old .NET Framework, and many support libraries needed to be replaced.
• First, the bad news: I did not find a color picker control that works on .NET 5.0 WPF, so the Pad color picker is gone. It is replaced by a text-box where you can type in a 6-digit hex code. You should be able to pick the color through a different tool, though.
• Now the good news: .NET 5.0 comes with a "self-contained" application mode that does not require the .NET Runtime to be installed. So now the portable executable is truly portable and needs no framework or runtime install to work.
• The installer experience is also better, as the .NET 5.0 Runtime install is much faster than the old .NET Framework install.
• Enabled standard notifications on Windows 10 for when the encode queue completes. This was previously only on the Microsoft Store version, but now works for the installer version.
