I've been using AVR Studio 4 for years, along with WinAVR. Just today I decided on a whim to upgrade from 4.18 to 4.19, and suddenly it appears I need to install this new thing, AVR Toolchain Installer (never needed it before). So what is this new thing? Does it replace WinAVR? Should I install WinAVR after the Toolchain Installer?

Very confused...

It's winAvr under another name sort of thing. Apparently you can still use use the real winAvr also and it seems that the later is highly recomended.

I was going to install V4.19 but I don't really need it so I saved a few million electrons being wasted and also reduced the risk of a stroke.

All that's apparently changed between 4.18 and 4.19 is that 4.18 used to look to see if you had either Toolchain (first) or WinAVR (second) on your machine and at the creation of a "GCC project" it would set the default path to avr-gcc.exe and make.exe in the 5th tab of the project customisation dialog (even then if you had both installed it used to annoy me that it would therefore select "toolchain"). In 4.19 it now only looks automatically for toolchain. But all you do is set things (after project creation) as shown in the following and it will use WinAVR as before...
