Go 1.8, the next version of Google's open source language, is moving toward general availability, with a release candidate featuring improvements in compilation and HTTP. The final Version 1.8 is due in February.
According to draft notes, the release candidate features updates to the compiler back end for more efficient code. The back end, initially developed for Go 1.7 for 64-bit x86 systems, is based on static single assignment (SSA) form to generate more efficient code and to serve as a platform for optimizations like bounds check elimination. It now works on all architectures.
