Six years of Go

In August we released Go 1.5, the most significant release since Go 1. It features a completely redesigned garbage collector that makes the language more suitable for latency-sensitive applications; it marks the transition from a C-based compiler tool chain to one written entirely in Go; and it includes ports to new architectures, with better support for ARM processors (the chips that power most smartphones). These improvements make Go better suited to a broader range of tasks, a trend that we hope will continue over the coming years.

Improvements to tools continue to boost developer productivity. We introduced the execution tracer and the “go doc” command, as well as more enhancements to our various static analysis tools. We are also working on an official Go plugin for Sublime Text, with better support for other editors in the pipeline.

Early next year we will release more improvements in Go 1.6, including an SSA-based optimizing compiler back end, HTTP/2 support for net/http servers and clients, an official package vendoring mechanism, support for blocks in text and HTML templates, a memory sanitizer that checks both Go and C/C++ code, and the usual assortment of other improvements and fixes…
