How to represent a function's version history in Golang function documentation?

In Golang function documentation, use the // Version History comment block to record the function version history. It lists function changes in version order, making it easier for users to track updates: each line starts with a version number, followed by a description of the update. Version history annotations provide important information about function changes and help users understand the background of the changes.

Indicates the version history of the function in the Golang function document

Uses the // Version History comment block record in the Golang function document The version history of a function is very useful. Here's how it's used:

// Version History
//
// - 0.0.1: Initial version
// - 0.0.2: Added support for negative numbers
// - 0.0.3: Fixed a bug in the input validation

This comment block appears at the top of the function document and allows you to list changes to the function in version order. Each line begins with a version number, followed by a description of the version update.

Practical Case

Consider the following Add function:

// Add returns the sum of two integers.
func Add(a, b int) int {
    return a + b
}

Over time, the documentation for this function may evolve into:

// Version History
//
// - 0.0.1: Initial version
// - 0.0.2: Added support for negative numbers
// - 0.0.3: Fixed a bug in the input validation
// - 0.0.4: Improved efficiency by using compiler-optimized code

// Add returns the sum of two integers.
func Add(a, b int) int {
    return a + b
}

This type of version history annotation provides important information about function changes, making it easier for users to track updates and understand the background of changes.
