* test(harness): read agent plan from the scoped store
The store-scoping change moved an agent's plan from the default table
key agent/{name}/plan to its own table (database "agent", table {name},
key "plan"). The plan-delegate harness tests still read the old key and
failed with 'not found'; read through store.Scope(mem, "agent", name)
like the agent does.
* docs: orient agents-first across README, landing, and docs overview
Lead with agents (then services and flows), surface MCP + A2A as the
interop story, and frame agents as services. Landing hero and feature
grid reordered agents-first with an A2A gateway card.
* v6: module path go-micro.dev/v6, TLS secure by default, NewService
Cut v6. Three breaking changes, bundled so the major bump is paid once:
- Module path go-micro.dev/v5 -> go-micro.dev/v6 across all imports + go.mod.
- TLS verification on by default (was off). MICRO_TLS_SECURE removed;
MICRO_TLS_INSECURE=true opts out for self-signed/dev.
- micro.NewService(name, opts...) is the canonical service constructor,
symmetric with NewAgent/NewFlow; micro.New kept as a deprecated alias;
the old name-less NewService(opts...) removed. Generators emit NewService.
Also ports the JWT auth token provider in-module (go-micro.dev/v6/auth/jwt/token
on golang-jwt/jwt/v5), dropping the v5-pinned github.com/micro/plugins/v5/auth/jwt
and the deprecated dgrijalva/jwt-go.
Docs/README/landing updated to v6 and @latest; v5->v6 migration guide added;
CHANGELOG cut as [6.0.0]. Blog posts left at their historical versions.

Registry
The registry is responsible for service discovery in Go Micro. It allows services to register themselves and discover other services.
Features
- Service registration and deregistration
- Service lookup
- Watch for changes
Implementations
Go Micro supports multiple registry backends, including:
- MDNS (default)
- Consul
- Etcd
- NATS
You can configure the registry when initializing your service.
Plugins Location
Registry plugins live in this repository under go-micro.dev/v6/registry/<plugin> (e.g., consul, etcd, nats). Import the desired package and pass it via micro.Registry(...).
Configure via environment
MICRO_REGISTRY=etcd MICRO_REGISTRY_ADDRESS=127.0.0.1:2379 micro server
Common variables:
MICRO_REGISTRY: selects the registry implementation (mdns,consul,etcd,nats).MICRO_REGISTRY_ADDRESS: comma-separated list of registry addresses.
Backend-specific variables:
- Etcd:
ETCD_USERNAME,ETCD_PASSWORDfor authenticated clusters.
Example Usage
Here's how to use a custom registry (e.g., Consul) in your Go Micro service:
package main
import (
"go-micro.dev/v6"
"go-micro.dev/v6/registry/consul"
)
func main() {
reg := consul.NewRegistry()
service := micro.NewService(
micro.Registry(reg),
)
service.Init()
service.Run()
}
