The Go Engineer v2.1.0-rc.1 Release Notes

Release Candidate Milestone

The Go Engineer v2.1.0-rc.1 is now published as the first release candidate for the v2.1 curriculum line.

This release marks the point where the beta-complete curriculum moves into final release validation. The architecture, learner routing, validator, maintainer workflow, and RC release gate are now aligned on the release/v2 branch.

What's New in v2.1.0-rc.1

RC Gate & Release Discipline

• formalized the v2.1.0-rc.1 release gate for release/v2
• documented the exact smoke matrix required before tagging RC and final v2 releases
• aligned RELEASE.md, MAINTAINER-CHECKLIST.md, and CHANGELOG.md with the active RC branch model

Stabilized v2.1 Curriculum Line

• carried forward the completed 12-section v2.1 architecture from the beta-complete snapshot
• kept learner-facing docs and curriculum metadata coherent with the current root-stage structure
• preserved the stricter single-validator contract introduced during beta hardening

Verified RC Smoke Matrix

The release/v2 branch tip was verified with the maintained RC checks:

• go build ./...
• go test ./...
• go test ./08-quality-test/01-quality-and-performance/testing/benchmarks -bench="." -benchmem -count=1
• go run ./01-getting-started/2-hello-world
• go run ./01-getting-started/4-dev-environment
• go run ./scripts/validate_curriculum.go

GitHub Actions remained the authoritative path for the race-detection gate where the local Windows environment lacks a working CGO C toolchain.

Release Tracking

• RC gate issue: #368
• Release-prep PR: #369
• Base branch: release/v2

Next

This release candidate opens the final validation window for v2.1.0.

From here, work should focus on:

• final RC feedback
• any release-blocker fixes discovered during validation
• cutting the stable v2.1.0 release once RC validation is complete
