Go announced Go 1.15 version on 11 Aug 2020. Highlighted updates and features include Substantial improvements to the Go linker, Improved allocation for small objects at high core counts, X.509 CommonName deprecation, GOPROXY supports skipping proxies that return errors, New embedded tzdata package, Several Core Library improvements and more.
As Go promise for maintaining backward compatibility. After upgrading to the latest Go 1.15 version, almost all existing Golang applications or programs continue to compile and run as older Golang version.

Building Web Applications with Go
Welcome, gopher! You're not a gopher? Well, this workshop is for gophers, or people that use the Go programming language. But fear not if you've never written any Go before! I'd recommend you learn the basics for the language first with the Go tour.
This workshop has been run a couple of times with an instructor leading. The goal of this repo is to make it as easy as possible for individuals to follow the content by themselves. If you get stuck at any point, feel free to file issues asking questions.
To go through this you will need the following:
GOPATHby following the How to Write Go Code tutorial.
There's a lot to say about how to build web applications, in Go or any other language. But we only have one day so we won't try to cover too much. Instead we'll cover the basics, so you'll be able to explore other solutions and frameworks later.
The workshops is divided in eleven sections:
These are places where you can find more information for Go:
My favorite aspect of Go is its community, and you are now part of it too. Welcome!
As a newcomer to the Go community you might have questions or get blocked at some point. This is completely normal, and we're here to help you. Some of the places where gophers tend to hang out are:
This is not an official Google product (experimental or otherwise), it is just code that happens to be owned by Google.
We spoke to Rob Pike, the co-author of the Go programming language, about a career spanning four decades, the evolution of Go over the last ten years, and into the future.
Evrone: Unlike many developers today, you started your career decades ago at Bell Labs. What’s been the biggest change in the way we develop software that you can think of, given your rare perspective?
**Rob: **The scale is much bigger today. Not just of the computers and the network, but the programs themselves. All of Unix version 6 (circa 1975) fits comfortably on a single RK05 disk pack, which has just over 2MB of storage, with lots of room left over for user software. And that was a fine computing environment, or at least seemed like one at the time. Although I can, of course, explain much of the growth, it is astonishing and perhaps not all of it is justified.

httppackage to create and initialize HTTPS servers in Go.
In the “Simple Hello World Server” lesson, we learned about
net/http package, how to create routes and how
[ServeMux](https://golang.org/pkg/net/http/#ServeMux) works. In the “Running multiple HTTP servers” lesson, we learned about
[Server](https://golang.org/pkg/net/http/#Server) structure and how to run multiple HTTP servers concurrently.
In this lesson, we are going to create an HTTPS server using both Go’s standard server configuration and custom configuration (using
[_Server_](https://golang.org/pkg/net/http/#Server) structure). But before this, we need to know what HTTPS really is?
HTTPS is a big topic of discussion in itself. Hence while writing this lesson, I published an article just on “How HTTPS works?”. I advise you to read this lesson first before continuing this article. In this article, I’ve also described the encryption paradigm and SSL certificates generation process.
If we recall the simplest HTTP server example from previous lessons, we only need
http.``[ListenAndServe](https://golang.org/pkg/net/http/#ListenAndServe) function to start an HTTP server and
http.``[HandleFunc](https://golang.org/pkg/net/http/#HandleFunc) to register a response handler for a particular endpoint.
In the example above, when we run the command
go run server.go , it will start an HTTP server on port
9000. By visiting
http://localhost:9000 URL in a browser, you will be able to see a
Hello World! message on the screen.
As we know, the
nil argument to
ListenAndServe() call invokes Go to use the
[DefaultServeMux](https://golang.org/pkg/net/http/#DefaultServeMux) response multiplexer, which is the default instance of
ServeMux structure provided globally by the Go. The
HandleFunc() call adds a response handler for a specific route on the multiplexer instance.
http.ListenAndServe() call uses the Go’s standard HTTP server configuration, however, in the previous lesson, how we can customize a server using
[Server](https://golang.org/pkg/net/http/#Server) structure type.
To start an HTTPS server, all we need do is to call
ServerAndListenTLS method with some configuration. Just like
ServeAndListen method, this method is available on both the
http package and the
http.``[ServeAndListenTLS](https://golang.org/pkg/net/http/#ListenAndServeTLS) method uses the Go’s standard server implementation, however, both
[Server](https://golang.org/pkg/net/http/#Server) instance and
Server.``[ServeAndListenTLS](https://golang.org/pkg/net/http/#Server.ListenAndServeTLS) method can be configured for our needs.

Here is a reading list of blog posts about Go. It aspires to include only the most useful and relevant material that anyone writing Go should eventually read. By definition, the list is a work in progress.
Rather than being comprehensive, the list is a curated selection fixed at 200 entries.
Go is growing fast and so are the number of blog posts about it. If an interested reader knows of a great post not on this list, please open an issue with a link to the post. Not every blog post linked in an issue will make its way into the list. Nonetheless, the issue list (both open and closed) is a good source of additional reading material.
NOTE: Any new additions will need to replace something else on the list to keep it at a fixed length.
See Go Books for a list of books, both free and paid.
