1.3.0

What's Changed

• Enable whole module optimization by default for --compilation_mode opt builds. Pass --features=-swift.opt_uses_wmo to restore the previous behavior
• Support env in swift_test, thanks @maxwellE!
• Add ability to use PathToUnderscores in proto to Swift generation. Enabled with --features swift.generate_path_to_underscores_from_proto_files, thanks @mattrobmattrob!
• Add Swift 5.6 feature for partially explicit modules that can be used in place of VFS overlays to better support incremental compilation. Enabled with swift.use_explicit_swift_module_map
• Fix incremental compilation issue with emitting Objective-C headers
• Transition --proto_compiler instead of patching rules_proto to better support --@build_bazel_rules_swift//swift:universal_tools, thanks @thii!
• Match Swift Package Manager behavior for main entry point binaries
• Update index-import to use a universal binary, thanks @brentleyjones!
• Update rules_proto

This release is compatible with 5.x LTS and bazel 6.x rolling releases.
