Golang Weekly issue 596 covers a range of Go ecosystem news. Highlights include Solod, a Go subset that compiles to C for systems programming without a runtime; constmap, an immutable Go map offering 3x faster lookups and 6x less memory at the cost of limited key types; Google's Agent Development Kit for Go reaching v1.0 with OpenTelemetry, self-healing logic, and safety guardrails; and several articles on Go patterns including multi-step sequences, the outbox pattern with Postgres, and a proposal for composite type constraints.
