           ## Install
 
-          Extract the .tgz file and copy the lifecycle binaries into a [build image](https://github.com/buildpacks/spec/blob/main/platform.md#build-image). The build image can then be orchestrated by a platform implementation such as the [pack CLI](https://github.com/buildpack/pack) or [tekton](https://github.com/tektoncd/catalog/tree/main/task/buildpacks).
+          Extract the .tgz file and copy the lifecycle binaries into a [build stack base image](https://github.com/buildpack/spec/blob/master/platform.md#stacks). The build image can then be orchestrated by a platform implementation such as the [pack CLI](https://github.com/buildpack/pack) or [tekton](https://github.com/tektoncd/catalog/blob/master/task/buildpacks/0.1/README.md).
 
           ## Lifecycle Image
 
           An OCI image containing the lifecycle binaries is available at buildpacksio/lifecycle:${{ env.LIFECYCLE_VERSION }}.

+* Some of the Windows acceptance tests use license restricted base images. By default, the docker deamon will not publish layers from these images when pushing to a registry which can result in test failures with error messages such as: `Ignoring image "X" because it was corrupt`. To fix these failures you must [enable pushing nondistributable artifacts](https://docs.docker.com/engine/reference/commandline/dockerd/#allow-push-of-nondistributable-artifacts) to the test registry by adding the following to your Docker Desktop Engine config:

 ### Testing GitHub actions on forks
 
 The lifecycle release process involves chaining a series of GitHub actions together such that:
 * The "build" workflow creates the artifacts
-  * .tgz files containing the lifecycle binaries, shasums for the .tgz files, an SBOM, etc.
+  * .tgz files containing the lifecycle binaries, shasums for the .tgz files, a cosign public key, an SBOM, etc.
   * OCI images containing the lifecycle binaries, tagged with their commit sha (for more information, see RELEASE.md)
 * The "draft-release" workflow finds the artifacts and downloads them, creating the draft release
 * The "post-release" workflow re-tags the OCI images that were created during the "build" workflow with the release version
 
 It can be rather cumbersome to test changes to these workflows, as they are heavily intertwined. Thus we recommend forking the buildpacks/lifecycle repository in GitHub and running through the entire release process end-to-end.
 For the fork, it is necessary to add the following secrets:
+* COSIGN_PASSWORD (see [cosign](https://github.com/sigstore/cosign#generate-a-keypair))
+* COSIGN_PRIVATE_KEY
 * DOCKER_PASSWORD (if not using ghcr.io)
 * DOCKER_USERNAME (if not using ghcr.io)
 
 The tools/test-fork.sh script can be used to update the source code to reflect the state of the fork. 
-It can be invoked like so: `./tools/test-fork.sh <registry repo name>`
+It can be invoked like so: `./tools/test-fork.sh <registry repo name> <path to cosign public key>`

-# Release Finalization
+## Release Finalization
 
-## Types of releases
-
-#### New minor
-* For newly supported Platform or Buildpack API versions, or breaking changes (e.g., API deprecations).
-
-#### Pre-release aka release candidate
-* Ideally we should ship a pre-release (waiting a few days for folks to try it out) before we ship a new minor.
-* We typically don't ship pre-releases for patches or backports.
-
-#### New patch
-* For go version updates, CVE fixes / dependency bumps, bug fixes, etc.
-* Review the latest commits on `main` to determine if any are unacceptable for a patch - if there are commits that should be excluded, branch off the latest tag for the current minor and cherry-pick commits over.
-
-#### Backport
-* New patch for an old minor. Typically, to help folks out who haven't yet upgraded from [unsupported APIs](https://github.com/buildpacks/rfcs/blob/main/text/0110-deprecate-apis.md).
-* For go version updates, CVE fixes / dependency bumps, bug fixes, etc.
-* Branch off the latest tag for the desired minor.
-
-## Release Finalization Steps
-
-### Step 1 - Prepare
-
-Determine the type of release ([new minor](#new-minor), [pre-release](#pre-release-aka-release-candidate), [new patch](#new-patch), or [backport](#backport)) and prepare the branch accordingly.
-
-**To prepare the release branch:**
-1. Check open PRs for any dependabot updates that should be merged.
-1. Create a release branch in the format `release/0.99.0-rc.1` (for pre-releases) or `release/0.99.0` (for final releases).
-   * New commits to this branch will trigger the `build` workflow and produce a lifecycle image: `buildpacksio/lifecycle:<commit sha>`.
+To cut a pre-release:
 1. If applicable, ensure the README is updated with the latest supported apis (example PR: https://github.com/buildpacks/lifecycle/pull/550).
-   * For final releases (not pre-releases), remove the pre-release note (`*`) for the latest apis.
+1. Create a release branch in the format `release/0.99.0-rc.1`. New commits to this branch will trigger the `build` workflow and produce a lifecycle image: `buildpacksio/lifecycle:<commit sha>`.
+1. When ready to cut the release, manually trigger the `draft-release` workflow: Actions -> draft-release -> Run workflow -> Use workflow from branch: `release/0.99.0-rc.1`. This will create a draft release on GitHub using the artifacts from the `build` workflow run for the latest commit on the release branch.
+1. Edit the release notes as necessary.
+1. Perform any manual validation of the artifacts.
+1. When ready to publish the release, edit the release page and click "Publish release". This will trigger the `post-release` workflow that will re-tag the lifecycle image from `buildpacksio/lifecycle:<commit sha>` to `buildpacksio/lifecycle:0.99.0` but will NOT update the `latest` tag.
 
-**For final releases (not pre-releases):**
+To cut a release:
 1. Ensure the relevant spec APIs have been released.
 1. Ensure the `lifecycle/0.99.0` milestone on the [docs repo](https://github.com/buildpacks/docs/blob/main/RELEASE.md#lump-changes) is complete, such that every new feature in the lifecycle is fully explained in the `release/lifecycle/0.99` branch on the docs repo, and [migration guides](https://github.com/buildpacks/docs/tree/main/content/docs/reference/spec/migration) (if relevant) are included.
-
-### Step 2 - Publish the Release
-
-1. Manually trigger the `draft-release` workflow: Actions -> draft-release -> Run workflow -> Use workflow from branch: `release/<release version>`. This will create a draft release on GitHub using the artifacts from the `build` workflow run for the latest commit on the release branch.
+1. Create a release branch in the format `release/0.99.0`. New commits to this branch will trigger the `build` workflow and produce a lifecycle image: `buildpacksio/lifecycle:<commit sha>`.
+1. If applicable, ensure the README is updated with the latest supported apis (example PR: https://github.com/buildpacks/lifecycle/pull/550) and remove the pre-release note for the latest apis.
+1. When ready to cut the release, manually trigger the `draft-release` workflow: Actions -> draft-release -> Run workflow -> Use workflow from branch: `release/0.99.0`. This will create a draft release on GitHub using the artifacts from the `build` workflow run for the latest commit on the release branch.
 1. Edit the release notes as necessary.
-1. Perform any manual validation of the artifacts as necessary (usually none).
-1. Edit the release page and click "Publish release".
-   * This will trigger the `post-release` workflow that will re-tag the lifecycle image from `buildpacksio/lifecycle:<commit sha>` to `buildpacksio/lifecycle:<release version>`.
-     * For final releases ONLY, this will also re-tag the lifecycle image from `buildpacksio/lifecycle:<commit sha>` to `buildpacksio/lifecycle:latest`.
-
-### Step 3 - Follow-up
-
-**For pre-releases:**
-* Ask the relevant teams to try out the pre-released artifacts.
-
-**For final releases:**
-* Update the `main` branch to remove the pre-release note in [README.md](https://github.com/buildpacks/lifecycle/blob/main/README.md) and/or merge `release/0.99.0` into `main`.
-* Ask the learning team to merge the `release/lifecycle/0.99` branch into `main` on the docs repo.
-
-## Go version updates
-
-Go version updates should be released as a [new minor](#new-minor) or [new patch](#new-patch) release.
-
-### New Patch
-
-If the go patch is in [actions/go-versions](https://github.com/actions/go-versions/pulls?q=is%3Apr+is%3Aclosed) then CI should pull it in automatically without any action needed.
-We simply need to create the release branch and let the pipeline run.
-
-### New Minor
-
-We typically do this when the existing patch version exceeds 6 - e.g., `1.22.6`. This means we have about 6 months to upgrade before the current minor becomes unsupported due to the introduction of the new n+2 minor.
-
-#### Steps
-1. Update go.mod
-1. Search for the old `major.minor`, there are a few files that need to be updated (example PR: https://github.com/buildpacks/lifecycle/pull/1405/files)
-1. Update the linter to a version that supports the current `major.minor`
-1. Fix any lint errors as necessary
+1. Perform any manual validation of the artifacts.
+1. When ready to publish the release, edit the release page and click "Publish release". This will trigger the `post-release` workflow that will re-tag the lifecycle image from `buildpacksio/lifecycle:<commit sha>` to `buildpacksio/lifecycle:0.99.0` and `buildpacksio/lifecycle:latest`.
+1. Once released
+- Update the `main` branch to remove the pre-release note in [README.md](https://github.com/buildpacks/lifecycle/blob/main/README.md) and/or merge `release/0.99.0` into `main`.
+- Ask the learning team to merge the `release/lifecycle/0.99` branch into `main` on the docs repo.
