v0.20.0
To use v0.20.0 of Service Weaver, run the following commands in the root of your application's module:
go get github.com/ServiceWeaver/weaver@v0.20.0 # Update the weaver module.
go install github.com/ServiceWeaver/weaver/cmd/weaver@v0.20.0 # Update the weaver command line tool.Requiring Go 1.21
Service Weaver now requires Go 1.21. This allows us to use the new slog package. See #520 for details.
Deployer API Changes
We made some small simplifications to the deployer API in v0.20.0. The SingleProcess field was removed from EnvelopeInfo (#521), and the Pid field was removed from WeaveletInfo (#522). The InternalPort field in EnvelopeInfo was replaced with InternalAddress (#526). These changes shouldn't affect Service Weaver applications. Only deployer implementations need to be updated.
Codegen Changes
weaver generate now generates new reflection-based stubs (#481). These stubs will be used in our ongoing work on implementing deterministic simulation.
