Go 1.8 released

The Go team has announced therelease of Go 1.8. "The compiler back end introduced in Go 1.7 for 64-bit x86 is now usedon all architectures, and those architectures should see significant performanceimprovements. For instance, the CPU time required by our benchmarkprograms was reduced by 20-30% on 32-bit ARM systems. There are also somemodest performance improvements in this release for 64-bit x86 systems. Thecompiler and linker have been made faster. Compile times should be improvedby about 15% over Go 1.7. There is still more work to be done in this area:expect faster compilation speeds in future releases." See the release notes for more details.
