Release manager: @tisonkun

Target version: 0.7.0

Current phase: release preparation

Runbook: RELEASE.md

One-time release infrastructure

• Create dist/dev/incubator/asyncband.
• Create dist/release/incubator/asyncband.
• Publish the release-manager key in KEYS: 8B37 4472 FAD3 28E1 7F47 9863 B379 691F C6E2 98DD.
• Configure the protected GitHub release environment for version tags and required reviewers.
• Smoke-test the non-publishing path of the Release workflow.
• Confirm the crates.io Trusted Publisher matches repository apache/asyncband, workflow release.yml, and environment release.

Release preparation

• Use v0.6.7-compat as the previous Asyncband release tag; v0.6.7 belongs to the MEA history.
• Merge #236, which fixes the semver audit, pool doctests, and release runbook.
• Freeze the 0.7.0 scope and decide which open performance changes move to 0.7.1.
• Prepare and merge the release PR: set asyncband to 0.7.0, refresh Cargo.lock, and create a dated changelog section with a new empty Unreleased section.
• Review and acknowledge every breaking API item reported by cargo x semver --release-version 0.7.0 against CHANGELOG.md.
• Verify LICENSE, NOTICE, DISCLAIMER, source headers, and bundled dependencies.
• Run cargo x lint, cargo x check, cargo x test --no-capture, the MSRV test, and cargo publish --package asyncband --locked --dry-run on the release commit.
• Record the merged release commit as RELEASE_COMMIT.

Release candidate

• Create and push signed tag v0.7.0-rc.1 from RELEASE_COMMIT.
• Confirm the Release workflow validates the RC tag and does not run the crates.io publish job.
• Build apache-asyncband-0.7.0-incubating-src.tar.gz from the signed RC tag in a clean clone.
• Create and verify the detached ASCII-armored signature and SHA-512 checksum.
• Verify the source archive contents, legal files, tests, and Cargo package dry-run.
• Stage the candidate at dist/dev/incubator/asyncband/0.7.0-rc.1/ and verify every vote-email link.
