Go 1.7 is released
15 August 2016
Today we are happy to announce the release of Go 1.7.
You can get it from the download page.
There are several significant changes in this release: a port for
Linux on IBM z Systems (s390x),
compiler improvements, the addition of the context package,
and support for hierarchical tests and benchmarks.
A new compiler back end, based on static single-assignment form (SSA),
has been under development for the past year.
By representing a program in SSA form, a compiler may perform advanced optimizations more easily.
This new back end generates more compact, more efficient code that includes
bounds check elimination and
common subexpression elimination.
We observed a 5–35% speedup across our benchmarks.
For now, the new backend is only available for the 64-bit x86 platform (“amd64”),
but we’re planning
