 Today the Go team is happy to announce the release of Go 1.8.
-You can get it from the [[https://golang.org/dl/][download page]].
+You can get it from the [download page](https://golang.org/dl/).
 There are significant performance improvements and changes across the standard library.
 
-The compiler back end introduced in [[https://blog.golang.org/go1.7][Go 1.7]] for 64-bit x86 is now used
-on all architectures, and those architectures should see significant [[https://golang.org/doc/go1.8#compiler][performance improvements]].
+The compiler back end introduced in [Go 1.7](https://blog.golang.org/go1.7) for 64-bit x86 is now used
+on all architectures, and those architectures should see significant [performance improvements](https://golang.org/doc/go1.8#compiler).
 For instance, the CPU time required by our benchmark programs was reduced by 20-30% on 32-bit ARM systems.
 There are also some modest performance improvements in this release for 64-bit x86 systems.
 The compiler and linker have been made faster.
 Compile times should be improved by about 15% over Go 1.7.
 There is still more work to be done in this area: expect faster compilation speeds in future releases.
 
-Garbage collection pauses should be [[https://golang.org/doc/go1.8#gc][significantly shorter]],
+Garbage collection pauses should be [significantly shorter](https://golang.org/doc/go1.8#gc),
 usually under 100 microseconds and often as low as 10 microseconds.

+The HTTP server adds support for [HTTP/2 Push](https://golang.org/doc/go1.8#h2push),
 allowing servers to preemptively send responses to a client.
 This is useful for minimizing network latency by eliminating roundtrips.
-The HTTP server also adds support for [[https://golang.org/doc/go1.8#http_shutdown][graceful shutdown]],
+The HTTP server also adds support for [graceful shutdown](https://golang.org/doc/go1.8#http_shutdown),
 allowing servers to minimize downtime by shutting down only after serving all requests that are in flight.
 
-[[https://golang.org/pkg/context/][Contexts]] (added to the standard library in Go 1.7)
+[Contexts](https://golang.org/pkg/context/) (added to the standard library in Go 1.7)
 provide a cancelation and timeout mechanism.
-Go 1.8 [[https://golang.org/doc/go1.8#more_context][adds]] support for contexts in more parts of the standard library,
-including the [[https://golang.org/pkg/database/sql][`database/sql`]] and [[https://golang.org/pkg/net][`net`]] packages
-and [[http://beta.golang.org/pkg/net/http/#Server.Shutdown][`Server.Shutdown`]] in the `net/http` package.
+Go 1.8 [adds](https://golang.org/doc/go1.8#more_context) support for contexts in more parts of the standard library,
+including the [`database/sql`](https://golang.org/pkg/database/sql) and [`net`](https://golang.org/pkg/net) packages
+and [`Server.Shutdown`](http://beta.golang.org/pkg/net/http/#Server.Shutdown) in the `net/http` package.
 
-It's now much simpler to sort slices using the newly added [[https://golang.org/pkg/sort/#Slice][`Slice`]]
+It's now much simpler to sort slices using the newly added [`Slice`](https://golang.org/pkg/sort/#Slice)
 function in the `sort` package. For example, to sort a slice of structs by their `Name` field:
 
 	sort.Slice(s, func(i, j int) bool { return s[i].Name < s[j].Name })
 
 Go 1.8 includes many more additions, improvements, and fixes.

+To celebrate the release, Go User Groups around the world are holding [release parties](https://github.com/golang/go/wiki/Go-1.8-release-party) this week.
 Release parties have become a tradition in the Go community, so if you missed out this time, keep an eye out when 1.9 nears.
 
 Thank you to over 200 contributors who helped with this release.
