This major version upgrade from Go 1.18 to 1.26rc2 spans multiple significant releases and introduces language changes, tooling updates, and new platform requirements that require careful validation. The use of a release candidate (rc2) adds further risk.

Highlights:

• Language Change: Go 1.22 changed for loop variable semantics to prevent common bugs. Code relying on the old behavior, where loop variables were shared across iterations, may break. This is a critical change to validate.
• Platform Support: Support for older operating systems has been dropped. Go 1.21 requires macOS 10.15+ and Go 1.25 requires macOS 12+. Go 1.20 was the last release to support Windows 7/8.

Source: Go documentation
Recommendation: Thoroughly test application behavior, especially loops with goroutines or closures. Verify build and deployment environments meet the new OS requirements before merging.
