Note
This patch release was brought to you by the Shipyard team.
This is a Windows bugfix release. If you use Linux or macOS v0.40.0 should be fine.
🚒 Bugfix for Windows
If you run Kubo on Windows, v0.40.0 can crash after running for a while. The daemon starts fine and works normally at first, but eventually hits a memory corruption in Go's network I/O layer and dies. This is likely caused by an upstream Go 1.26 regression in overlapped I/O handling that has known issues (go#77142, #11214).
This patch release downgrades the Go toolchain from 1.26 to 1.25, which does not have this bug. If you are running Kubo on Windows, upgrade to v0.40.1. We will switch back to Go 1.26.x once the upstream fix lands.
