Go 1.26 interactive tour New with expressions, type-safe error checking, and faster everything.

Go 1.26 is out, and the announcement says:

"Over the next few weeks, follow-up blog posts will cover some of the topics in more detail. Check back later."

So you can wait a few weeks OR you can read my interactive Go 1.26 tour right away:

This is my flag.

It means unity, freedom, peace, democracy, equality, civilization, diversity, rule of law, science, beauty and strength.

There is nothing more important to fight for our values!

If you don’t like it, pack your bags and leave!

Long live Europe!

Bluesky is proof that cryptocurrency isn't a core tenant of decentralization. The team demonstrated extreme levels of pragmatism by leveraging new and existing technologies to produce something people actually use.
