golang version difference

Golang (also known as Go language) is an open source programming language that was developed by Google in 2007 and first released in 2009. Due to Golang's efficiency and ease of use, it has become the language of choice for many developers. However, in the development process of Golang, different versions of Golang have also appeared. What are the differences between these versions? Let’s learn about them one by one below.

1. Go 1.x

Go 1.x is the initial release. It is the stable version of Golang and the most widely used version currently. Go 1.0 was released in 2012, Go 1.1 was released in 2013, and then the Go language plans to release a new stable version every year. The focus of the Go 1.x version is to improve the performance and stability of Golang, while adding some new features and solving some problems at the language level.

2. Go 2.0

Go 2.0 is the next major version of Golang. It aims to solve some problems existing in the 1.x version, while also adding some new features. The designers of Go 2.0 have made some suggestions, including better error handling, more versatility, better concurrency handling, better module support, etc. The designers of Go 2.0 will also explore how to improve Golang's performance and security.

3. Go 1.5

Go 1.5 is an important version of the Go language, released in 2015. Its focus is on improving performance and concurrency. Go 1.5 adds some new features, including code generators, function types, unique types, and more. In Go 1.5, Golang's caching and scheduling mechanisms have also been updated and optimized.

4. Go 1.11

Go 1.11 is a milestone version of Golang, released in 2018. This version adds some new features, including module support, WebAssembly support, GRPC (Google Remote Procedure Call) support, etc. Go 1.11 also optimizes external dependency libraries and improves the dependency resolution algorithm.

5. Go 1.12

Go 1.12 is an important version of Golang, released in 2019. This version mainly enhances the performance and security of the Go language. Go 1.12 improves GC performance and performance of larger heap memory operations, and also provides support for TLS 1.3. In addition, Go 1.12 also strengthens dependency management and adds support for "anonymous import".

The above are some major versions of Golang, which have different improvements and updates in terms of performance, features, and security. Developers can choose the corresponding version for development according to their own needs. At the same time, Golang will continue to be updated and upgraded during the development process to provide developers with better tools and support.
