Poem

🐰 A version bump, so small and neat,
From 1.25.2 to 1.25.4—what a treat!
The cert bug that made our export fail,
Is fixed in the Go update without fail.
Now akash export runs with glee,
Happy as a rabbit, wild and free! 🌟

3-3: Go version bump appropriately addresses the certificate regression and requires no other synchronization.

The upgrade from go 1.25.2 to go 1.25.4 directly fixes the x509 SAN dNSName malformed panic (golang/go#75828). Verification confirms:

• go1.25.4 is a valid released version
• CI workflows dynamically detect the Go version from go.mod using ./script/tools.sh gotoolchain, so no manual workflow updates are needed
• No other version declarations in Dockerfiles or configuration files require synchronization

This patch-level bump is backward-compatible and carries minimal risk.
