Thanks for the pull request, @shuan1026. Here we need to bump the golangci-lint version defined: in

bbolt/.github/workflows/tests-template.yml

Line 55 in 1f5a036

version: v2.1.6

The minimum version with Go 1.25 support is v2.4.0. But I'd suggest using the latest v2.10.1.

Pls fix the workflow failure. It seems that the env variable GOTOOLCHAIN isn't correctly configured. cc @ivanvc @joshjms
