Summary

  • Configure Changesets to only major-bump peer dependents when the updated peer range is out of range.
  • Add a publish-time release-major guard with a branch-local RELEASE_VERSION constant.
  • Set RELEASE_VERSION: 5 on main; the stable backport should set it to 4.

Why

Stable release PR #2352 bumped @workflow/ai from 6.0.0 to 7.0.0 even though @workflow/ai only received a workflow peer dependency update. Changesets does this by default for peer dependents when the peer has a non-patch release, even if the new version is still within the peer range.

The Changesets config change prevents that dependency-only major bump class. The release workflow guard is the final lock: before changesets/action can publish, it checks the packages in the checked-out branch and fails if any public, non-ignored workspace package has a major version that does not match RELEASE_VERSION.

Implementation

  • .changeset/config.json opts into onlyUpdatePeerDependentsWhenOutOfRange.
  • .github/scripts/check-release-major.js reads packages/*/package.json, skips private and Changesets-ignored packages, and fails on package versions outside the configured release major.
  • .github/workflows/release.yml runs that script before dependency installation and before the Changesets publish step.

Validation

  • node --test .github/scripts/check-release-major.test.js
  • pnpm exec biome check .github/scripts/check-release-major.js .github/scripts/check-release-major.test.js .github/workflows/release.yml .changeset/avoid-peer-major-bumps.md .changeset/config.json
  • node .github/scripts/check-release-major.js 5
  • node .github/scripts/check-release-major.js 4 fails as expected on this v5 branch.
  • Synthetic Changesets release-plan check: workflow 4.4.0 -> 4.5.0 no longer bumps @workflow/ai, while workflow 4.4.0 -> 5.0.0 still bumps @workflow/ai.

Backport

Backport this to stable, but set RELEASE_VERSION: 4 in .github/workflows/release.yml on the stable branch.

does this actually work? as in - will the script be able to detect the future major versions BEFORE pnpm ci:version is run? I thought that command had to run first before the new major version would appear in the package.json files that this script is trying to find and for detection

I think there's a changeset cli command you can just run (changeset status maybe) that gives you the version numbers - and it can use that to detect the versions in the repo and fail on that

i also don't understand why we're comparing refs and doing PUSH_BEFORE? we should simply fail CI if the branch actively has any workflow package versions that doesn't match the hardcoded major version number

codex: Updated this to remove the ref comparison / PUSH_BEFORE path entirely. The release job now runs node .github/scripts/check-release-major.js "$RELEASE_VERSION" against the checked-out branch before changesets/action, and that script fails if any public, non-ignored workspace package has a major version that does not match the branch-local RELEASE_VERSION. I also renamed the guard/tests, added coverage for ignored/private packages, reran the focused checks, and updated the PR title/description to match.

codex: I didn’t switch this guard to the Changesets CLI because the thing we need to block is publish, not creation of the Version Packages PR. By the time the release workflow is on the publish path, package.json has already been versioned, so checking the checked-out package manifests against branch-local RELEASE_VERSION is enough and simpler. changeset status would be useful if we also wanted to block producing a bad Version Packages PR earlier, but it isn’t needed to prevent publishing.

already done upstream so this change should go away once you update branch

Only major-bump peer dependents when updated workspace peer ranges fall out of range, and block release publishes that contain package major version upgrades outside the branch's release major.

Backport to stable failed for 67dcb0e due to a workflow error (backport job run).

This is usually an infrastructure problem (e.g. the configured AI model could not be found, an AI Gateway error, or an opencode crash) rather than a merge conflict. Check the job logs linked above for details.

Once the underlying issue is fixed, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

Summary

  • Configure Changesets to only major-bump peer dependents when the updated peer range is out of range.
  • Add a publish-time release-major guard with a branch-local RELEASE_VERSION constant.
  • Set RELEASE_VERSION: 5 on main; the stable backport should set it to 4.

Why

Stable release PR #2352 bumped @workflow/ai from 6.0.0 to 7.0.0 even though @workflow/ai only received a workflow peer dependency update. Changesets does this by default for peer dependents when the peer has a non-patch release, even if the new version is still within the peer range.

The Changesets config change prevents that dependency-only major bump class. The release workflow guard is the final lock: before changesets/action can publish, it checks the packages in the checked-out branch and fails if any public, non-ignored workspace package has a major version that does not match RELEASE_VERSION.

Implementation

  • .changeset/config.json opts into onlyUpdatePeerDependentsWhenOutOfRange.
  • .github/scripts/check-release-major.js reads packages/*/package.json, skips private and Changesets-ignored packages, and fails on package versions outside the configured release major.
  • .github/workflows/release.yml runs that script before dependency installation and before the Changesets publish step.

Validation

  • node --test .github/scripts/check-release-major.test.js
  • pnpm exec biome check .github/scripts/check-release-major.js .github/scripts/check-release-major.test.js .github/workflows/release.yml .changeset/avoid-peer-major-bumps.md .changeset/config.json
  • node .github/scripts/check-release-major.js 5
  • node .github/scripts/check-release-major.js 4 fails as expected on this v5 branch.
  • Synthetic Changesets release-plan check: workflow 4.4.0 -> 4.5.0 no longer bumps @workflow/ai, while workflow 4.4.0 -> 5.0.0 still bumps @workflow/ai.

Backport

Backport this to stable, but set RELEASE_VERSION: 4 in .github/workflows/release.yml on the stable branch.

does this actually work? as in - will the script be able to detect the future major versions BEFORE pnpm ci:version is run? I thought that command had to run first before the new major version would appear in the package.json files that this script is trying to find and for detection

I think there's a changeset cli command you can just run (changeset status maybe) that gives you the version numbers - and it can use that to detect the versions in the repo and fail on that

i also don't understand why we're comparing refs and doing PUSH_BEFORE? we should simply fail CI if the branch actively has any workflow package versions that doesn't match the hardcoded major version number

codex: Updated this to remove the ref comparison / PUSH_BEFORE path entirely. The release job now runs node .github/scripts/check-release-major.js "$RELEASE_VERSION" against the checked-out branch before changesets/action, and that script fails if any public, non-ignored workspace package has a major version that does not match the branch-local RELEASE_VERSION. I also renamed the guard/tests, added coverage for ignored/private packages, reran the focused checks, and updated the PR title/description to match.

codex: I didn’t switch this guard to the Changesets CLI because the thing we need to block is publish, not creation of the Version Packages PR. By the time the release workflow is on the publish path, package.json has already been versioned, so checking the checked-out package manifests against branch-local RELEASE_VERSION is enough and simpler. changeset status would be useful if we also wanted to block producing a bad Version Packages PR earlier, but it isn’t needed to prevent publishing.

already done upstream so this change should go away once you update branch

Only major-bump peer dependents when updated workspace peer ranges fall out of range, and block release publishes that contain package major version upgrades outside the branch's release major.

Backport to stable failed for 67dcb0e due to a workflow error (backport job run).

This is usually an infrastructure problem (e.g. the configured AI model could not be found, an AI Gateway error, or an opencode crash) rather than a merge conflict. Check the job logs linked above for details.

Once the underlying issue is fixed, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

Summary

  • Configure Changesets to only major-bump peer dependents when the updated peer range is out of range.
  • Add a publish-time release-major guard with a branch-local RELEASE_VERSION constant.
  • Set RELEASE_VERSION: 5 on main; the stable backport should set it to 4.

Why

Stable release PR #2352 bumped @workflow/ai from 6.0.0 to 7.0.0 even though @workflow/ai only received a workflow peer dependency update. Changesets does this by default for peer dependents when the peer has a non-patch release, even if the new version is still within the peer range.

The Changesets config change prevents that dependency-only major bump class. The release workflow guard is the final lock: before changesets/action can publish, it checks the packages in the checked-out branch and fails if any public, non-ignored workspace package has a major version that does not match RELEASE_VERSION.

Implementation

  • .changeset/config.json opts into onlyUpdatePeerDependentsWhenOutOfRange.
  • .github/scripts/check-release-major.js reads packages/*/package.json, skips private and Changesets-ignored packages, and fails on package versions outside the configured release major.
  • .github/workflows/release.yml runs that script before dependency installation and before the Changesets publish step.

Validation

  • node --test .github/scripts/check-release-major.test.js
  • pnpm exec biome check .github/scripts/check-release-major.js .github/scripts/check-release-major.test.js .github/workflows/release.yml .changeset/avoid-peer-major-bumps.md .changeset/config.json
  • node .github/scripts/check-release-major.js 5
  • node .github/scripts/check-release-major.js 4 fails as expected on this v5 branch.
  • Synthetic Changesets release-plan check: workflow 4.4.0 -> 4.5.0 no longer bumps @workflow/ai, while workflow 4.4.0 -> 5.0.0 still bumps @workflow/ai.

Backport

Backport this to stable, but set RELEASE_VERSION: 4 in .github/workflows/release.yml on the stable branch.

does this actually work? as in - will the script be able to detect the future major versions BEFORE pnpm ci:version is run? I thought that command had to run first before the new major version would appear in the package.json files that this script is trying to find and for detection

I think there's a changeset cli command you can just run (changeset status maybe) that gives you the version numbers - and it can use that to detect the versions in the repo and fail on that

i also don't understand why we're comparing refs and doing PUSH_BEFORE? we should simply fail CI if the branch actively has any workflow package versions that doesn't match the hardcoded major version number

codex: Updated this to remove the ref comparison / PUSH_BEFORE path entirely. The release job now runs node .github/scripts/check-release-major.js "$RELEASE_VERSION" against the checked-out branch before changesets/action, and that script fails if any public, non-ignored workspace package has a major version that does not match the branch-local RELEASE_VERSION. I also renamed the guard/tests, added coverage for ignored/private packages, reran the focused checks, and updated the PR title/description to match.

codex: I didn’t switch this guard to the Changesets CLI because the thing we need to block is publish, not creation of the Version Packages PR. By the time the release workflow is on the publish path, package.json has already been versioned, so checking the checked-out package manifests against branch-local RELEASE_VERSION is enough and simpler. changeset status would be useful if we also wanted to block producing a bad Version Packages PR earlier, but it isn’t needed to prevent publishing.

already done upstream so this change should go away once you update branch

Only major-bump peer dependents when updated workspace peer ranges fall out of range, and block release publishes that contain package major version upgrades outside the branch's release major.

Backport to stable failed for 67dcb0e due to a workflow error (backport job run).

This is usually an infrastructure problem (e.g. the configured AI model could not be found, an AI Gateway error, or an opencode crash) rather than a merge conflict. Check the job logs linked above for details.

Once the underlying issue is fixed, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

Summary

  • Configure Changesets to only major-bump peer dependents when the updated peer range is out of range.
  • Add a publish-time release-major guard with a branch-local RELEASE_VERSION constant.
  • Set RELEASE_VERSION: 5 on main; the stable backport should set it to 4.

Why

Stable release PR #2352 bumped @workflow/ai from 6.0.0 to 7.0.0 even though @workflow/ai only received a workflow peer dependency update. Changesets does this by default for peer dependents when the peer has a non-patch release, even if the new version is still within the peer range.

The Changesets config change prevents that dependency-only major bump class. The release workflow guard is the final lock: before changesets/action can publish, it checks the packages in the checked-out branch and fails if any public, non-ignored workspace package has a major version that does not match RELEASE_VERSION.

Implementation

  • .changeset/config.json opts into onlyUpdatePeerDependentsWhenOutOfRange.
  • .github/scripts/check-release-major.js reads packages/*/package.json, skips private and Changesets-ignored packages, and fails on package versions outside the configured release major.
  • .github/workflows/release.yml runs that script before dependency installation and before the Changesets publish step.

Validation

  • node --test .github/scripts/check-release-major.test.js
  • pnpm exec biome check .github/scripts/check-release-major.js .github/scripts/check-release-major.test.js .github/workflows/release.yml .changeset/avoid-peer-major-bumps.md .changeset/config.json
  • node .github/scripts/check-release-major.js 5
  • node .github/scripts/check-release-major.js 4 fails as expected on this v5 branch.
  • Synthetic Changesets release-plan check: workflow 4.4.0 -> 4.5.0 no longer bumps @workflow/ai, while workflow 4.4.0 -> 5.0.0 still bumps @workflow/ai.

Backport

Backport this to stable, but set RELEASE_VERSION: 4 in .github/workflows/release.yml on the stable branch.

does this actually work? as in - will the script be able to detect the future major versions BEFORE pnpm ci:version is run? I thought that command had to run first before the new major version would appear in the package.json files that this script is trying to find and for detection

I think there's a changeset cli command you can just run (changeset status maybe) that gives you the version numbers - and it can use that to detect the versions in the repo and fail on that

i also don't understand why we're comparing refs and doing PUSH_BEFORE? we should simply fail CI if the branch actively has any workflow package versions that doesn't match the hardcoded major version number

codex: Updated this to remove the ref comparison / PUSH_BEFORE path entirely. The release job now runs node .github/scripts/check-release-major.js "$RELEASE_VERSION" against the checked-out branch before changesets/action, and that script fails if any public, non-ignored workspace package has a major version that does not match the branch-local RELEASE_VERSION. I also renamed the guard/tests, added coverage for ignored/private packages, reran the focused checks, and updated the PR title/description to match.

codex: I didn’t switch this guard to the Changesets CLI because the thing we need to block is publish, not creation of the Version Packages PR. By the time the release workflow is on the publish path, package.json has already been versioned, so checking the checked-out package manifests against branch-local RELEASE_VERSION is enough and simpler. changeset status would be useful if we also wanted to block producing a bad Version Packages PR earlier, but it isn’t needed to prevent publishing.

already done upstream so this change should go away once you update branch

Only major-bump peer dependents when updated workspace peer ranges fall out of range, and block release publishes that contain package major version upgrades outside the branch's release major.

Backport to stable failed for 67dcb0e due to a workflow error (backport job run).

This is usually an infrastructure problem (e.g. the configured AI model could not be found, an AI Gateway error, or an opencode crash) rather than a merge conflict. Check the job logs linked above for details.

Once the underlying issue is fixed, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

Summary

  • Configure Changesets to only major-bump peer dependents when the updated peer range is out of range.
  • Add a publish-time release-major guard with a branch-local RELEASE_VERSION constant.
  • Set RELEASE_VERSION: 5 on main; the stable backport should set it to 4.

Why

Stable release PR #2352 bumped @workflow/ai from 6.0.0 to 7.0.0 even though @workflow/ai only received a workflow peer dependency update. Changesets does this by default for peer dependents when the peer has a non-patch release, even if the new version is still within the peer range.

The Changesets config change prevents that dependency-only major bump class. The release workflow guard is the final lock: before changesets/action can publish, it checks the packages in the checked-out branch and fails if any public, non-ignored workspace package has a major version that does not match RELEASE_VERSION.

Implementation

  • .changeset/config.json opts into onlyUpdatePeerDependentsWhenOutOfRange.
  • .github/scripts/check-release-major.js reads packages/*/package.json, skips private and Changesets-ignored packages, and fails on package versions outside the configured release major.
  • .github/workflows/release.yml runs that script before dependency installation and before the Changesets publish step.

Validation

  • node --test .github/scripts/check-release-major.test.js
  • pnpm exec biome check .github/scripts/check-release-major.js .github/scripts/check-release-major.test.js .github/workflows/release.yml .changeset/avoid-peer-major-bumps.md .changeset/config.json
  • node .github/scripts/check-release-major.js 5
  • node .github/scripts/check-release-major.js 4 fails as expected on this v5 branch.
  • Synthetic Changesets release-plan check: workflow 4.4.0 -> 4.5.0 no longer bumps @workflow/ai, while workflow 4.4.0 -> 5.0.0 still bumps @workflow/ai.

Backport

Backport this to stable, but set RELEASE_VERSION: 4 in .github/workflows/release.yml on the stable branch.

does this actually work? as in - will the script be able to detect the future major versions BEFORE pnpm ci:version is run? I thought that command had to run first before the new major version would appear in the package.json files that this script is trying to find and for detection

I think there's a changeset cli command you can just run (changeset status maybe) that gives you the version numbers - and it can use that to detect the versions in the repo and fail on that

i also don't understand why we're comparing refs and doing PUSH_BEFORE? we should simply fail CI if the branch actively has any workflow package versions that doesn't match the hardcoded major version number

codex: Updated this to remove the ref comparison / PUSH_BEFORE path entirely. The release job now runs node .github/scripts/check-release-major.js "$RELEASE_VERSION" against the checked-out branch before changesets/action, and that script fails if any public, non-ignored workspace package has a major version that does not match the branch-local RELEASE_VERSION. I also renamed the guard/tests, added coverage for ignored/private packages, reran the focused checks, and updated the PR title/description to match.

codex: I didn’t switch this guard to the Changesets CLI because the thing we need to block is publish, not creation of the Version Packages PR. By the time the release workflow is on the publish path, package.json has already been versioned, so checking the checked-out package manifests against branch-local RELEASE_VERSION is enough and simpler. changeset status would be useful if we also wanted to block producing a bad Version Packages PR earlier, but it isn’t needed to prevent publishing.

already done upstream so this change should go away once you update branch

Only major-bump peer dependents when updated workspace peer ranges fall out of range, and block release publishes that contain package major version upgrades outside the branch's release major.

Backport to stable failed for 67dcb0e due to a workflow error (backport job run).

This is usually an infrastructure problem (e.g. the configured AI model could not be found, an AI Gateway error, or an opencode crash) rather than a merge conflict. Check the job logs linked above for details.

Once the underlying issue is fixed, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

Summary

  • Configure Changesets to only major-bump peer dependents when the updated peer range is out of range.
  • Add a publish-time release-major guard with a branch-local RELEASE_VERSION constant.
  • Set RELEASE_VERSION: 5 on main; the stable backport should set it to 4.

Why

Stable release PR #2352 bumped @workflow/ai from 6.0.0 to 7.0.0 even though @workflow/ai only received a workflow peer dependency update. Changesets does this by default for peer dependents when the peer has a non-patch release, even if the new version is still within the peer range.

The Changesets config change prevents that dependency-only major bump class. The release workflow guard is the final lock: before changesets/action can publish, it checks the packages in the checked-out branch and fails if any public, non-ignored workspace package has a major version that does not match RELEASE_VERSION.

Implementation

  • .changeset/config.json opts into onlyUpdatePeerDependentsWhenOutOfRange.
  • .github/scripts/check-release-major.js reads packages/*/package.json, skips private and Changesets-ignored packages, and fails on package versions outside the configured release major.
  • .github/workflows/release.yml runs that script before dependency installation and before the Changesets publish step.

Validation

  • node --test .github/scripts/check-release-major.test.js
  • pnpm exec biome check .github/scripts/check-release-major.js .github/scripts/check-release-major.test.js .github/workflows/release.yml .changeset/avoid-peer-major-bumps.md .changeset/config.json
  • node .github/scripts/check-release-major.js 5
  • node .github/scripts/check-release-major.js 4 fails as expected on this v5 branch.
  • Synthetic Changesets release-plan check: workflow 4.4.0 -> 4.5.0 no longer bumps @workflow/ai, while workflow 4.4.0 -> 5.0.0 still bumps @workflow/ai.

Backport

Backport this to stable, but set RELEASE_VERSION: 4 in .github/workflows/release.yml on the stable branch.

does this actually work? as in - will the script be able to detect the future major versions BEFORE pnpm ci:version is run? I thought that command had to run first before the new major version would appear in the package.json files that this script is trying to find and for detection

I think there's a changeset cli command you can just run (changeset status maybe) that gives you the version numbers - and it can use that to detect the versions in the repo and fail on that

i also don't understand why we're comparing refs and doing PUSH_BEFORE? we should simply fail CI if the branch actively has any workflow package versions that doesn't match the hardcoded major version number

yeah, using changeset CLI is better. Will update it

codex: Updated this to remove the ref comparison / PUSH_BEFORE path entirely. The release job now runs node .github/scripts/check-release-major.js "$RELEASE_VERSION" against the checked-out branch before changesets/action, and that script fails if any public, non-ignored workspace package has a major version that does not match the branch-local RELEASE_VERSION. I also renamed the guard/tests, added coverage for ignored/private packages, reran the focused checks, and updated the PR title/description to match.

codex: I didn’t switch this guard to the Changesets CLI because the thing we need to block is publish, not creation of the Version Packages PR. By the time the release workflow is on the publish path, package.json has already been versioned, so checking the checked-out package manifests against branch-local RELEASE_VERSION is enough and simpler. changeset status would be useful if we also wanted to block producing a bad Version Packages PR earlier, but it isn’t needed to prevent publishing.

already done upstream so this change should go away once you update branch

Only major-bump peer dependents when updated workspace peer ranges fall out of range, and block release publishes that contain package major version upgrades outside the branch's release major.

Backport to stable failed for 67dcb0e due to a workflow error (backport job run).

This is usually an infrastructure problem (e.g. the configured AI model could not be found, an AI Gateway error, or an opencode crash) rather than a merge conflict. Check the job logs linked above for details.

Once the underlying issue is fixed, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

Summary

  • Configure Changesets to only major-bump peer dependents when the updated peer range is out of range.
  • Add a publish-time release-major guard with a branch-local RELEASE_VERSION constant.
  • Set RELEASE_VERSION: 5 on main; the stable backport should set it to 4.

Why

Stable release PR #2352 bumped @workflow/ai from 6.0.0 to 7.0.0 even though @workflow/ai only received a workflow peer dependency update. Changesets does this by default for peer dependents when the peer has a non-patch release, even if the new version is still within the peer range.

The Changesets config change prevents that dependency-only major bump class. The release workflow guard is the final lock: before changesets/action can publish, it checks the packages in the checked-out branch and fails if any public, non-ignored workspace package has a major version that does not match RELEASE_VERSION.

Implementation

  • .changeset/config.json opts into onlyUpdatePeerDependentsWhenOutOfRange.
  • .github/scripts/check-release-major.js reads packages/*/package.json, skips private and Changesets-ignored packages, and fails on package versions outside the configured release major.
  • .github/workflows/release.yml runs that script before dependency installation and before the Changesets publish step.

Validation

  • node --test .github/scripts/check-release-major.test.js
  • pnpm exec biome check .github/scripts/check-release-major.js .github/scripts/check-release-major.test.js .github/workflows/release.yml .changeset/avoid-peer-major-bumps.md .changeset/config.json
  • node .github/scripts/check-release-major.js 5
  • node .github/scripts/check-release-major.js 4 fails as expected on this v5 branch.
  • Synthetic Changesets release-plan check: workflow 4.4.0 -> 4.5.0 no longer bumps @workflow/ai, while workflow 4.4.0 -> 5.0.0 still bumps @workflow/ai.

Backport

Backport this to stable, but set RELEASE_VERSION: 4 in .github/workflows/release.yml on the stable branch.

does this actually work? as in - will the script be able to detect the future major versions BEFORE pnpm ci:version is run? I thought that command had to run first before the new major version would appear in the package.json files that this script is trying to find and for detection

I think there's a changeset cli command you can just run (changeset status maybe) that gives you the version numbers - and it can use that to detect the versions in the repo and fail on that

i also don't understand why we're comparing refs and doing PUSH_BEFORE? we should simply fail CI if the branch actively has any workflow package versions that doesn't match the hardcoded major version number

codex: Updated this to remove the ref comparison / PUSH_BEFORE path entirely. The release job now runs node .github/scripts/check-release-major.js "$RELEASE_VERSION" against the checked-out branch before changesets/action, and that script fails if any public, non-ignored workspace package has a major version that does not match the branch-local RELEASE_VERSION. I also renamed the guard/tests, added coverage for ignored/private packages, reran the focused checks, and updated the PR title/description to match.

codex: I didn’t switch this guard to the Changesets CLI because the thing we need to block is publish, not creation of the Version Packages PR. By the time the release workflow is on the publish path, package.json has already been versioned, so checking the checked-out package manifests against branch-local RELEASE_VERSION is enough and simpler. changeset status would be useful if we also wanted to block producing a bad Version Packages PR earlier, but it isn’t needed to prevent publishing.

already done upstream so this change should go away once you update branch

Only major-bump peer dependents when updated workspace peer ranges fall out of range, and block release publishes that contain package major version upgrades outside the branch's release major.

Backport to stable failed for 67dcb0e due to a workflow error (backport job run).

This is usually an infrastructure problem (e.g. the configured AI model could not be found, an AI Gateway error, or an opencode crash) rather than a merge conflict. Check the job logs linked above for details.

Once the underlying issue is fixed, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

Summary

  • Configure Changesets to only major-bump peer dependents when the updated peer range is out of range.
  • Add a publish-time release-major guard with a branch-local RELEASE_VERSION constant.
  • Set RELEASE_VERSION: 5 on main; the stable backport should set it to 4.

Why

Stable release PR #2352 bumped @workflow/ai from 6.0.0 to 7.0.0 even though @workflow/ai only received a workflow peer dependency update. Changesets does this by default for peer dependents when the peer has a non-patch release, even if the new version is still within the peer range.

The Changesets config change prevents that dependency-only major bump class. The release workflow guard is the final lock: before changesets/action can publish, it checks the packages in the checked-out branch and fails if any public, non-ignored workspace package has a major version that does not match RELEASE_VERSION.

Implementation

  • .changeset/config.json opts into onlyUpdatePeerDependentsWhenOutOfRange.
  • .github/scripts/check-release-major.js reads packages/*/package.json, skips private and Changesets-ignored packages, and fails on package versions outside the configured release major.
  • .github/workflows/release.yml runs that script before dependency installation and before the Changesets publish step.

Validation

  • node --test .github/scripts/check-release-major.test.js
  • pnpm exec biome check .github/scripts/check-release-major.js .github/scripts/check-release-major.test.js .github/workflows/release.yml .changeset/avoid-peer-major-bumps.md .changeset/config.json
  • node .github/scripts/check-release-major.js 5
  • node .github/scripts/check-release-major.js 4 fails as expected on this v5 branch.
  • Synthetic Changesets release-plan check: workflow 4.4.0 -> 4.5.0 no longer bumps @workflow/ai, while workflow 4.4.0 -> 5.0.0 still bumps @workflow/ai.

Backport

Backport this to stable, but set RELEASE_VERSION: 4 in .github/workflows/release.yml on the stable branch.

does this actually work? as in - will the script be able to detect the future major versions BEFORE pnpm ci:version is run? I thought that command had to run first before the new major version would appear in the package.json files that this script is trying to find and for detection

I think there's a changeset cli command you can just run (changeset status maybe) that gives you the version numbers - and it can use that to detect the versions in the repo and fail on that

i also don't understand why we're comparing refs and doing PUSH_BEFORE? we should simply fail CI if the branch actively has any workflow package versions that doesn't match the hardcoded major version number

yeah, using changeset CLI is better. Will update it

codex: Updated this to remove the ref comparison / PUSH_BEFORE path entirely. The release job now runs node .github/scripts/check-release-major.js "$RELEASE_VERSION" against the checked-out branch before changesets/action, and that script fails if any public, non-ignored workspace package has a major version that does not match the branch-local RELEASE_VERSION. I also renamed the guard/tests, added coverage for ignored/private packages, reran the focused checks, and updated the PR title/description to match.

codex: I didn’t switch this guard to the Changesets CLI because the thing we need to block is publish, not creation of the Version Packages PR. By the time the release workflow is on the publish path, package.json has already been versioned, so checking the checked-out package manifests against branch-local RELEASE_VERSION is enough and simpler. changeset status would be useful if we also wanted to block producing a bad Version Packages PR earlier, but it isn’t needed to prevent publishing.

already done upstream so this change should go away once you update branch

Only major-bump peer dependents when updated workspace peer ranges fall out of range, and block release publishes that contain package major version upgrades outside the branch's release major.

Backport to stable failed for 67dcb0e due to a workflow error (backport job run).

This is usually an infrastructure problem (e.g. the configured AI model could not be found, an AI Gateway error, or an opencode crash) rather than a merge conflict. Check the job logs linked above for details.

Once the underlying issue is fixed, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:
