Go end of life: end of support by version
Google · Development & DevOps
For Go by Google, patchletter knows 12 support cycles. 10 of them have already ended and receive no more security updates. The current version of Go is 1.27.0. The cycles come from the open endoflife.date project, last reconciled on 26/08/2026.
When does support end for which Go version?
A cycle is a maintained version line. Where a date is given, support ends on that day — after it the vendor ships no more security updates for that line.

Where does the EOL data for Go come from?
From the open endoflife.date project, which collects vendors' official support commitments. patchletter reconciles the cycles daily; the Go data is as of 26/08/2026. In case of doubt the vendor's own lifecycle page applies — patchletter deliberately stores no vendor full texts.
