## TL;DR

Alright, this was discussed during today's working group (23rd September 2026), and the decision was to even be proactive around update go version on supported release branches. Essentially, golang supports 2 versions at time (at the time of writing, 1.26 and 1.27), so we should make sure to use either one of them on the release branch (and main of course) we support. I think I'll close this issue and create a new one to discuss how we can do this (aka what level of automation, etc..)

## When to use

- You are dealing with this situation.
- The symptom matches: Do we care if dependabot bumps release branches' minimum Go version?.

## When NOT to use

- Unrelated issues with a different cause.
- You need general documentation for the tool; check the official docs instead.

## Variant phrasings

### Do we care if dependabot bumps release branches' minimum Go version?

## Why it happens

GitHub issue tektoncd/pipeline#10762 (closed, 1 comments, reported 2026-09-16): ## What happened `sigstore/sigstore` `v1.10.10` (released after `v1.10.9`) bumped its own `go.mod` from `go 1.25.0` to `go 1.27.0` (sigstore/sigstore#2415). Because Go's module graph rules take the max `go` directive across all dependencies, updating to `v1.10.10` forces the consuming `go.mod`'s `go` line up to `1.27.0` too , as a side effect of what dependabot presents as an unremarkable "patch" bump (`kind/misc`, `semver-patch`). This has now happened on two release branches: - **`release-v1.15.x`**: already merged via `[release-v1.15.x] bump github.com/sigstore/sigstore/pkg/signature/k

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- Behavior can change between releases; the linked source reflects the versions above.
- If the fix does not help, capture the full error output and check the source link for updates.
