Should You Transition Your Project to Go 1.18 Now?

Benefits of Upgrading to Go 1.18
In March 2022, Go (also known as Golang) rolled out version 1.18. A number of projects have already embraced its new features, prompting the question: is it the right moment for you to make the switch? Below are some compelling reasons to consider migrating.
Better Security
As with each new release, Go 1.18 addresses numerous potential security vulnerabilities, making it a safer choice for your projects.
Type Parameters (Generics)
The introduction of type parameters is a significant incentive for many developers to upgrade to Go 1.18. This long-awaited feature opens up various new opportunities for programming, responding to community requests over the years.
Fuzzing
Fuzzing offers a novel method for testing Go applications, enhancing their security and stability.
Improved Performance
In specific scenarios, Go 1.18 can deliver performance boosts of around 20%.
Workspaces
Managing dependencies is simplified through Go modules, which are widely utilized within the Go community. The challenge of handling multiple modules has been effectively tackled in Go 1.18 with the introduction of workspace mode.
Drawbacks of Migration
While there are many benefits, the disadvantages largely depend on the nature of your project, particularly distinguishing between applications (like CLIs and servers) and libraries.
Applications
For applications, there are minimal downsides to migrating to Go 1.18, aside from the necessity for users compiling your app (including all CI/CD systems) to upgrade to this version as well. Fortunately, this transition is typically quick and involves a one-time adjustment.
Libraries
Library maintainers should proceed with caution! Transitioning existing, exported functions to generics may necessitate a "breaking change," requiring all dependent projects to adapt for compatibility with your library's new version. Furthermore, new libraries utilizing generics can only be utilized by projects already upgraded to Go 1.18. Many libraries aim to maintain compatibility with older Go versions, thus limiting the usability of your library.
When Should You Migrate to Go 1.18?
Go maintains support for the last two major releases. Following this guideline, the optimal time to upgrade is upon the release of Go 1.19. Many projects have adopted a release policy that involves testing against the two latest major versions. When Go 1.19 arrives, both 1.18 and 1.19 will support generics, ensuring that all tests can pass.
Ultimately, the decision on when to migrate rests with you. For instance, if you are developing a library that exclusively utilizes generics (such as slice mapping or filtering), upgrading to Go 1.18 is essential. Likewise, if your library is primarily used by projects that have already transitioned to Go 1.18, making the upgrade now would be advantageous.
