Michael Pratt @prattmic.com · 20/09/2026If I’m going to submit them out of order then they don’t presubmit test quite right since the tests include the parents, but eh it’s usually close enough, so I only move a change out of the stack if it seems important. 100

Michael Pratt @prattmic.com · 25/08/2026To be clear, I don’t think this is a regression. Some calculations were adjusted slightly to ensure they are arch independent. You found an edge case where this actually resulted in a visible change. My guess is that on 1.26 this code needed to be one space wider to trigger the same behavior. 100

Michael Pratt @prattmic.com · 14/08/2026Ha, I feel you. Though given the context of how we got here (go.dev/blog/toolchain), it seems like the only obvious alternative would be for the toolchain to refuse to build and have you manually upgrade. If you do prefer that behavior, you can set GOTOOLCHAIN=local to get it.go.devForward Compatibility and Toolchain Management in Go 1.21 - The Go Programming LanguageGo 1.21 manages Go toolchains like any other dependency; you will never need to manually download and install a Go toolchain again. 010
