v3.1.0

3.1.0 - 2026-05-28

• TAG: v3.1.0
• COVERAGE: 95.01% -- 609/641 lines in 16 files
• BRANCH COVERAGE: 77.54% -- 107/138 branches in 16 files
• 36.78% documented

Added

• -w / --workers aliases for -n, matching the worker-count terminology used by other
  parallel test runners.
• turbo_tests2 fan, a generic worker fan-out command that runs an arbitrary command once per
  worker with TEST_ENV_NUMBER and PARALLEL_TEST_GROUPS set.
• --example-status-log FILE, which converts RSpec example-status persistence data into a
  parallel_tests-compatible runtime log so grouping can use example-level timing history.

Changed

• Worker subprocess JSON now forwards RSpec deprecation notifications to the parent reporter.
• Worker subprocess JSON now forwards RSpec profile output to the parent reporter.
• Fail-fast runs now report spec groups that were stopped before execution.
• Interrupted runs now report spec groups that had not finished before shutdown.

Fixed

• Reconstructed failure backtraces now filter internal turbo_tests2 frames.

• Coverage was refreshed by adding focused specs for the new CLI, reporting, formatter, and
  grouping behaviors.

• RSpec deprecation notification reconstruction now uses the public from_hash API so CI passes
  with RSpec versions where .new is private.

• The shim command result object no longer depends on Struct#keyword_init, restoring Ruby 2.4
  compatibility.

• Backtrace output specs now accept JRuby 9.2's legacy block in <main> frame wording.

• GitHub Actions test jobs now force kettle-test to use its direct RSpec runner so coverage
  aggregation remains stable while testing turbo_tests2 itself.

• GitHub Actions appraisal jobs now pass explicit parent-directory RSpec paths so direct RSpec
  runs execute the real suite instead of finding zero examples from gemfiles/.

• Spawned-process coverage setup now locates .simplecov_spawn.rb from the working directory
  instead of Bundler.root, so appraisal gemfiles do not point it at gemfiles/.

• The coverage workflow now uses the same hard coverage thresholds as local development.

• The dedicated coverage workflow now runs RSpec directly so coverage artifacts are written under
  the repository root for upload steps.

• Removed the advanced CodeQL workflow because GitHub CodeQL default setup is enabled and rejects
  SARIF uploads from advanced configurations.

Security

• Refreshed pinned GitHub Action SHAs.
• Added checksums for the v3.0.0 release artifacts.
