v3.21.1

What's Changed

• Update Speakeasy sponsor URL by @ndimares in #3707
  This update refreshes the sponsor URL for Speakeasy, ensuring that links to this Goa framework sponsor point to the correct location.

• Fix duplicate security schemes in generated code by @disintegrator in #3690
  This fix resolves a code generation bug that occurred when API designs used multiple security schemes of the same type. Previously, this would cause the generated Auther interface and endpoint initialization methods to contain duplicate code, breaking the build. Now, security schemes are properly deduplicated by type during code generation.

• Clean up CI to match Go 1.23+ requirement by @tchssk in #3711
  This change removes CI builds for older Go versions that are no longer supported. Since Goa already requires Go 1.23 or newer, this update ensures the continuous integration pipeline only tests against supported Go versions, streamlining the build process.

• Fix streaming support for aliased array types by @raphael in #3712
  This bug fix addresses an issue with streaming endpoints that use aliased array types, particularly when those types are defined with custom package paths. The fix ensures that streaming functionality works correctly with these type definitions.

• @disintegrator made their first contribution in #3690

Full Changelog: v3.21.0...v3.21.1

v3.21.0

New Features

This release adds native support for Server-Sent Events to Goa.

• Read the initial proposal
• Run the monitor example

Additionally this release changes how Goa generated OpenAPI specification examples for aliased primitive types.
Previously each attribute using such types would have to redefine examples. Goa now uses the type example
by default for all attributes of that type.

Minor Improvements

• Goa generated code now satisfies the latest staticcheck rules
• Better design error message in case of invalid use of the Payload DSL function

Bug Fixes

• Fixes in how newlines are generated (added missing newlines and removed extra newlines)
• The HTTP code generated for SkipResponseBodyEncodeDecode does not explicitly write a HTTP status
  code anymore. The behavior should be backwards compatible (the Go stdlib package will generate
  a 200 OK status if none was written) but makes it possible for user code to write any appropriate
  status code.

What's Changed

• Fix warning QF1004 of staticcheck by @mamo3gr in #3684
• Properly propagate alias types user examples by @raphael in #3685
• Use eval.InvalidArgError() to dsl.Payload() by @tchssk in #3689
