| Today the Go team is pleased to release Go 1.25. |
| You can find its binary archives and installers on the [download page](/dl/). |
| |
| Go 1.25 comes with improvements over Go 1.24 across |
| its [tools](/doc/go1.25#tools), |
| the [runtime](/doc/go1.25#runtime), |
| [compiler](/doc/go1.25#compiler), |
| [linker](/doc/go1.25#linker), |
| and the [standard library](/doc/go1.25#library), |
| including the addition of one [new package](/doc/go1.25#new-testingsynctest-package). |
| There are [port-specific](/doc/go1.25#ports) changes |
| and [`GODEBUG` settings](/doc/godebug#go-125) updates. |
| |
| Some of the additions in Go 1.25 are in an experimental stage |
| and become exposed only when you explicitly opt in. |
| Notably, a [new experimental garbage collector](/doc/go1.25#new-experimental-garbage-collector), |
| and a [new experimental `encoding/json/v2` package](/doc/go1.25#json_v2) |
| are available for you to try ahead of time and provide your feedback. |
| It really helps if you're able to do that! |
| |
| Please refer to the [Go 1.25 Release Notes](/doc/go1.25) for the complete list |
| of additions, changes and improvements in Go 1.25. |
| |
| Over the next few weeks, follow-up blog posts will cover some of the topics |
| relevant to Go 1.25 in more detail. Check back in later to read those posts. |
| |
| Thanks to everyone who contributed to this release by writing code, filing bugs, |
| trying out experimental additions, sharing feedback, and testing the release candidates. |
| Your efforts helped make Go 1.25 as stable as possible. |
| As always, if you notice any problems, please [file an issue](/issue/new). |
