⭐ Go 1.25 Released — Sadly Go 1.25’s release coincided with my vacation – what luck! Nonetheless, 1.25 is a solid release, focused on fixes, improvements, and tool upgrades, rather than language changes, making it an easy upgrade for most. Here are some of the highlights and further resources to check out:

• The final Go 1.25 release notes provide all the details of the release.
• A new, experimental garbage collector is available to try, behind the GOEXPERIMENT=greenteagc build-time option.
• Anton Zhiyanov's Go 1.25 interactive tour remains a great way to get up to speed with the few language tweaks there are, including WaitGroup.Go(), the v2 JSON package, and the now-generally-available testing/synctest package.
• Microsoft has issued a release of its own Go 1.25.0 build and *TinyGo* has a Go 1.25 build too (more on that below).
