why the go install package download from official website of go1.21 is less than go1.20?

[xie cui]

go1.20.7.darwin-arm64.tar.gzArchivemacOSARM6492MB

go1.21.0.darwin-arm64.tar.gzArchivemacOSARM6462MB

this size reduce about 30%.

why the size reduce a lot?

[Kurtis Rader]

All of the packages are significantly smaller -- not just those for macOS. So this isn't due to anything specific to the macOS package(s). Looking at the release notes for Go 1.21.0 I don't see an obvious explanation for the reduction. Downloading and extracting those two packages shows the contents have a proportional size difference:

> du -sh go1.20.7/ go1.21.0/

264M go1.20.7/

237M go1.21.0/

Most of the files and directories are larger in the 1.21.0 release. There are some notable exceptions. The main one, accounting for most of the decrease, is the tool directory: This is the `df -k` diff:

< 111520    ./pkg/tool/darwin_arm64
---
> 80704 ./pkg/tool/darwin_arm64

 That is a 3 MB reduction (28%) in the total size of the Go tools. Why are the Go tools so much smaller? I don't see an obvious answer in the release notes.

Looks like on-going work, finally completed in 1.21?

I think that for 1.21 the biggest difference is that we aren't
including debug info with the binaries in
$GOROOT/pkg/tool/$GOOS_$GOARCH. That change was made in
https://go.dev/cl/475378.
