Go language is a rapidly developing programming language. Through continuous updates and improvements, its functions become more powerful. When new versions are released, upgrading is the best way to ensure your applications and code stay up to date and most secure. Well, in this article, we will explore how to upgrade the Go language.

Understanding Go language versions

Before we delve into how to upgrade the Go language, it is first necessary to understand the number of Go language versions and the differences between them. Versions of the Go language include:

1. Major version (Go 1.x): This is the major version number of the running Go version. Go 1.x is the current major version of the Go language, which contains a series of minor versions and fixes.
2. Minor releases (Go 1.x.y): These releases contain new features, bug fixes, or performance improvements.
3. Patch releases (Go 1.x.y.z): These releases contain Bugfix updates that fix different security risks and fix specific bugs.

Therefore, we can conclude that upgrading the Go language means upgrading to the next minor or patched version of Go, that is, updating from Go 1.13 to Go 1.14.

How to upgrade the Go language

Based on understanding the Go language version, let’s take a look at the steps on how to upgrade the Go language.

Step 1: Back up your code

Before upgrading the Go language, it is best to back up your code first. This is very important as incorrect operation may cause code to be lost or changed. Please make sure that the backup is returned intact so that the original code can be restored if any errors occur.

Step 2: Download the new version

Download the latest version of the Go language. You can download the Go language installer from the official website (https://golang.org/dl/) and choose the version compatible with your operating system.

Step 3: Update environment variables

After installing the new Go version, you need to update your computer environment variables. You can check the current version by running the following command in the terminal:

go version

If the version has been updated, update the environment variables to reflect the new version update. You can update environment variables as follows:

Windows

1. Open Control Panel, then System and Security > System > Advanced System Settings.
2. Under the "Advanced" tab, click "Environment Variables".
3. Find the item named "Path" under User Variables or System Variables and click "Edit".
4. In the Edit Environment Variables dialog box, add the new Go path and click OK.

macOS and Linux

1. Run the following command in Terminal:

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Step 4: Compile and Test the Application

After completing the update of the environment variables, use the following command to compile your application and test whether it runs normally under the new version:

go build

go test

If your application does not run properly under the new version, please Check the code and dependencies to find the problem.

Step 5: Clean up the old version

When you confirm that the new version of the Go language can run your application smoothly, you need to delete the old version. You can uninstall it using the command line or in the control panel.

The method for uninstalling the Go language can vary by operating system, but generally includes:

Windows

1. Open Control Panel, then "Programs and Features."
2. In the software list, find the Go language.
3. Click "Uninstall" and follow the prompts.

macOS

1. Run the following command in the terminal:

sudo rm -rf /usr/local/go

2. Delete your ~/.bash_profile Path to any old versions of the Go language added in the file.

Linux

1. Run the following command in the terminal:

sudo rm -rf /usr/local/go

2. Delete your ~/.bashrc Path to any old versions of the Go language added in the file.

Conclusion

Through this article, we have learned how to upgrade the Go language and understood the main steps. Upgrading the Go language is one of the best ways to keep your code and applications up to date and most secure. Also, when upgrading, remember to back up your code and update environment variables to adapt to the new version of the Go language.
