Go 1.7 released

The latest Go release, version 1.7, arrives six months after 1.6. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility, which expects almost all Go programs to continue to compile and run as before.


The release includes a new code generation back end for 64-bit x86 systems, following a proposal from 2015 that has been under development since then. The new back end, based on SSA, generates more compact, more efficient code and provides a better platform for optimizations such as bounds check elimination. The new back end reduces the CPU time required by official benchmark programs by 5-35%, and the size of compiled binary file reduces as well,  can be 20-30% in some cases.
