What is new in Go 1.26?

In Go 1.26, profiling and tracing tools have been improved, and optimizations have been made to the standard library and compiler.

Main innovations:

• Improved support for profiling with pprof, added new metrics and capabilities for performance analysis.
• Extended the functionality of runtime/trace for more detailed analysis of program operation.
• Optimizations in the garbage collector, reducing pauses and increasing performance.
• Updates to the standard library, including improvements in the net/http and crypto packages.

Example of using new profiling features:

import (
    "runtime/pprof"
    "os"
)

func main() {
    f, _ := os.Create("cpu.prof")
    pprof.StartCPUProfile(f)
    defer pprof.StopCPUProfile()
    // program code
}

This allows collecting more accurate data about the application's operation.
