Release Notes

grpc/grpc-go

v1.40.0

Compare Source

Behavior Changes

• balancer: client channel no longer connects to idle subchannels that are returned by the pickers; LB policy should call SubConn.Connect instead. (#​4579)
  • This change is in line with existing documentation stating the balancer must call Connect on idle SubConns in order for them to connect, and is preparation for an upcoming change that transitions SubConns to the idle state when connections are lost. See https://pkg.go.dev/google.golang.org/grpc/balancer#SubConn for more details.
