-= Contributing to Spring Security
+_Have something you'd like to contribute to the framework? We welcome pull requests, but ask that you carefully read this document first to understand how best to submit them; what kind of changes are likely to be accepted; and what to expect from the Spring Security team when evaluating your submission._
 
-First off, thank you for taking the time to contribute! :+1: :tada:
+_Please refer back to this document as a checklist before issuing any pull request; this will save time for everyone!_

-== Code of Conduct
+= Similar but different
 
-This project is governed by the https://github.com/spring-projects/.github/blob/main/CODE_OF_CONDUCT.md[Spring code of conduct].
-By participating you are expected to uphold this code.
-Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.
+Each Spring module is slightly different from one another in terms of team size, number of issues, etc. Therefore, each project is managed slightly different. You will notice that this document is very similar to the https://github.com/spring-projects/spring-framework/wiki/Contributor-guidelines[Spring Framework Contributor guidelines]. However, there are some subtle differences between the two documents, so please be sure to read this document thoroughly.
 
-[[how-to-contribute]]
-== How to Contribute
+= Importing into IDE
 
-[[ask-questions]]
-=== Ask Questions
+The following provides information on setting up a development environment that can run the sample in https://www.springsource.org/sts[Spring Tool Suite 3.6.0+]. Other IDE's should work using Gradle's IDE support, but have not been tested.
 
-If you have a question, check Stack Overflow using
-https://stackoverflow.com/questions/tagged/spring-security+or+spring-ldap+or+spring-authorization-server+or+spring-session?tab=Newest[this list of tags].
-Find an existing discussion, or start a new one if necessary.
+* IDE Setup
+** Install Spring Tool Suite 3.6.0+
+** You will need the following plugins installed (can be found on the Extensions Page)
+*** Gradle Eclipse
+*** Groovy Eclipse
+* Importing the project into Spring Tool Suite
+** File -> Import… -> Gradle Project
 
-If you believe there is an issue, search through https://github.com/spring-projects/spring-security/issues[existing issues] trying a  few different ways to find discussions, past or current, that are related to the issue.
-Reading those discussions helps you to learn about the issue, and helps us to make a decision.
+As of new versions of Spring Tool Suite, you might need to install Groovy Eclipse pointing directly to the updated plugin location. To install Groovy Eclipse on Spring Tool Suite based on Eclipse Oxigen you must do the following steps:
 
-[[find-an-issue]]
-=== Find an Existing Issue
+Help -> Install New Software… -> Add the following URL into _Work with_ field:
+https://dist.springsource.org/snapshot/GRECLIPSE/e4.7/[https://dist.springsource.org/snapshot/GRECLIPSE/e4.7/]
 
-There are many issues in Spring Security with the labels https://github.com/spring-projects/spring-security/issues?q=is%3Aissue+is%3Aopen+label%3A%22status%3A+ideal-for-contribution%22[`ideal-for-contribution`] or https://github.com/spring-projects/spring-security/issues?q=is%3Aissue+is%3Aopen+label%3A%22status%3A+first-timers-only%22[`first-timers-only`] that are a great way to contribute to a discussion or <<submit-a-pull-request,to a PR>>.
-You can volunteer by commenting on these tickets, and we will assign them to you.
+= Understand the basics
 
-[[create-an-issue]]
-=== Create an Issue
+Not sure what a pull request is, or how to submit one? Take a look at GitHub's excellent https://help.github.com/articles/using-pull-requests[help documentation first].
 
-Reporting an issue or making a feature request is a great way to contribute.
-Your feedback and the conversations that result from it provide a continuous flow of ideas.
-However, before creating a ticket, please take the time to <<ask-questions,ask and research>> first.
+= Search GitHub issues; create an issue if necessary
 
-If you create an issue after a discussion on Stack Overflow, please provide a description in the issue instead of simply referring to Stack Overflow.
-The issue tracker is an important place of record for design discussions and should be self-sufficient.
+Is there already an issue that addresses your concern? Do a bit of searching in our https://github.com/spring-projects/spring-security/issues[GitHub issues] to see if you can find something similar. If not, please create a new issue before submitting a pull request unless the change is not a user facing issue.
 
-Once you're ready, create an issue on https://github.com/spring-projects/spring-security/issues[GitHub].
+= Discuss non-trivial contribution ideas with committers
 
-Many issues are caused by subtle behavior, typos, and unintended configuration.
-Creating a https://stackoverflow.com/help/minimal-reproducible-example[Minimal Reproducible Example] (starting with https://start.spring.io for example) of the problem helps the team quickly triage your issue and get to the core of the problem.
+If you're considering anything more than correcting a typo or fixing a minor bug, please discuss it on the https://gitter.im/spring-projects/spring-security[Spring Security Gitter] before submitting a pull request. We're happy to provide guidance but please spend an hour or two researching the subject on your own including searching the forums for prior discussions.
 
-We love contributors, and we may ask you to <<submit-a-pull-request,submit a PR with a fix>>.
+= Sign the Contributor License Agreement
 
-[[issue-lifecycle]]
-=== Issue Lifecycle
+If you have not previously done so, please fill out and submit the https://cla.pivotal.io/sign/spring[Contributor License Agreement].
 
-When an issue is first created, it is flagged `waiting-for-triage` waiting for a team member to triage it.
-Once the issue has been reviewed, the team may ask for further information if needed, and based on the findings, the issue is either assigned a target branch (or no branch if a feature) or is closed with a specific status.
-The target branch is https://spring.io/projects/spring-security#support[the earliest supported branch] where <<choose-a-branch,the change will be applied>>.
+= Create your branch from oldest maintenance branch
 
-When a fix is ready, the issue is closed and may still be re-opened until the fix is released.
-After that the issue will typically no longer be reopened.
-In rare cases if the issue was not at all fixed, the issue may be re-opened.
-In most cases however any follow-up reports will need to be created as new issues with a fresh description.
+Create your topic branch to be submitted as a pull request from the oldest impacted and supported maintenance branch.
+You can find the supported versions by looking at the https://github.com/spring-projects/spring-security/milestones[milestones page].
+Switch to a branch named `<major>.<minor>.x` from the smallest milestone in the format of `<major>.<minor>.<patch>(-<prerelease>)`.
+The spring team will ensure the code gets merged forward into additional branches.
 
-[[build-from-source]]
-=== Build from Source
+= Use short branch names
 
-See https://github.com/spring-projects/spring-security/tree/main#building-from-source[Build from Source] for instructions on how to check out, build, and import the Spring Security source code into your IDE.
+Branches used when submitting pull requests should preferably be named according to GitHub issues, e.g. `gh-1234` or `gh-1234-fix-npe`. Otherwise, use succinct, lower-case, dash (`-`) delimited names, such as `fix-warnings` or `fix-typo`. This is important, because branch names show up in the merge commits that result from accepting pull requests, and should be as expressive and concise as possible.
 
-[[code-style]]
-=== Source Code Style
+= Keep commits focused
 
-The wiki pages https://github.com/spring-projects/spring-framework/wiki/Code-Style[Code Style] and https://github.com/spring-projects/spring-framework/wiki/IntelliJ-IDEA-Editor-Settings[IntelliJ IDEA Editor Settings] define the source file coding standards we use along with some IDEA editor settings we customize.
+Remember each ticket should be focused on a single item of interest since the tickets are used to produce the changelog. Since each commit should be tied to a single GitHub issue, ensure that your commits are focused. For example, do not include an update to a transitive library in your commit unless the GitHub is to update the library. Reviewing your commits is essential before sending a pull request.
 
-To format the code as well as check the style, run `./gradlew format check`.
+= Mind the whitespace
 
-[[submit-a-pull-request]]
-=== Submit a Pull Request
+Please carefully follow the whitespace and formatting conventions already present in the framework.
 
-We are excited for your pull request! :heart:
+. Tabs, not spaces
+. Unix (LF), not dos (CRLF) line endings
+. Eliminate all trailing whitespace
+. Aim to wrap code at 120 characters, but favor readability over wrapping
+. Preserve existing formatting; i.e. do not reformat code for its own sake
+. Search the codebase using `git grep` and other tools to discover common naming conventions, etc.
+. UTF-8 encoding for Java sources and XML files
 
-Please do your best to follow these steps.
-Don't worry if you don't get them all correct the first time, we will help you.
+Whitespace management tips
+
+. You can use the https://marketplace.eclipse.org/content/anyedit-tools[AnyEdit Eclipse plugin] to ensure spaces are used and to clean up trailing whitespaces.
+. Use Git's `pre-commit.sample` hook to prevent invalid whitespace from being pushed out. You can enable it by moving `.git/hooks/pre-commit.sample` to `.git/hooks/pre-commit` and ensuring it is executable. For more information on hooks refer to https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks[https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks].

+= Add Apache license header to all new classes
 
-[[sign-cla]]
-1. If you have not previously done so, please sign the https://cla.spring.io/sign/spring[Contributor License Agreement].
-You will be reminded automatically when you submit the PR.
-[[create-an-issue]]
-1. Must you https://github.com/spring-projects/spring-security/issues/new/choose[create an issue] first? No, but it is recommended for features and larger bug fixes. It's easier discuss with the team first to determine the right fix or enhancement.
-For typos and straightforward bug fixes, starting with a pull request is encouraged.
-Please include a description for context and motivation.
-Note that the team may close your pull request if it's not a fit for the project.
-[[choose-a-branch]]
-1. Always check out the branch indicated in the milestone and submit pull requests against it (for example, for milestone `5.8.3` use the `5.8.x` branch).
-If there is no milestone, choose `main`.
-Once merged, the fix will be forwarded-ported to applicable branches including `main`.
-[[create-a-local-branch]]
-1. Create a local branch
-If this is for an issue, consider a branch name with the issue number, like `gh-22276`.
-[[write-tests]]
-1. Add documentation and JUnit Tests for your changes.
-[[update-copyright]]
-1. In all files you edited, if the copyright header is of the form 2002-20xx, update the final copyright year to the current year.
-[[add-since]]
-1. If on `main`, add `@since` JavaDoc attributes to new public APIs that your PR adds
-[[change-rnc]]
-1. If you are updating the XSD, please instead update the RNC file and then run `./gradlew :spring-security-config:rncToXsd`.
-[[format-code]]
-1. For each commit, build the code using `./gradlew format check`.
-This command ensures the code meets most of <<code-style,the style guide>>; a notable exception is import order.
-[[commit-atomically]]
-1. Choose the granularity of your commits consciously and squash commits that represent
-multiple edits or corrections of the same logical change.
-See https://git-scm.com/book/en/Git-Tools-Rewriting-History[Rewriting History section of Pro Git] for an overview of streamlining the commit history.
-[[format-commit-messages]]
-1. Format commit messages using 55 characters for the subject line, 72 characters per line
-for the description, followed by the issue fixed, for example, `Closes gh-22276`.
-See the https://git-scm.com/book/en/Distributed-Git-Contributing-to-a-Project#Commit-Guidelines[Commit Guidelines section of Pro Git] for best practices around commit messages, and use `git log` to see some examples.
-Present tense is preferred.

-If accepted, your contribution may be heavily modified as needed prior to merging.
-You will likely retain author attribution for your Git commits granted that the bulk of your changes remain intact.
-You may also be asked to rework the submission.
+= Update Apache license header to modified files as necessary
 
-If asked to make corrections, simply push the changes against the same branch, and your pull request will be updated.
-In other words, you do not need to create a new pull request when asked to make changes.
-When it is time to merge, you'll be asked to squash your commits.
+Always check the date range in the license header. For example, if you've modified a file in 2020 whose header still reads

+----
+ * Copyright 2002-2020 the original author or authors.
+----
+
+= Use @since tags for newly-added public API types and methods
+
+Example:
+
+----
+/**
+ * …
+ *
+ * @author First Last
+ * @since 5.4
+ * @see …
+ */
+----
+
+= Submit JUnit test cases for all behavior changes
+
+Search the codebase to find related unit tests and add additional `@Test` methods within.
+
+. Any new tests should end in the name `Tests` (note this is plural). For example, a valid name would be `FilterChainProxyTests`. An invalid name would be `FilterChainProxyTest`.
+. New test methods should not start with test. This is an old JUnit3 convention and is not necessary since the method is annotated with `@Test`.
+
+= Update spring-security-x.y.rnc for schema changes
+
+Update the https://www.relaxng.org[RELAX NG] schema `spring-security-x.y.rnc` instead of `spring-security-x.y.xsd` if you contribute changes to supported XML configuration. The XML schema file can be generated the following Gradle task:
+
+----
+./gradlew :spring-security-config:rncToXsd
+----
+
+Changes to the XML schema will be overwritten by the Gradle build task.
+
+= Squash commits
+
+Use `git rebase --interactive`, `git add --patch` and other tools to "squash" multiple commits into atomic changes. In addition to the man pages for `git`, there are https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History[many resources online] to help you understand how these tools work.
+
+= Use real name in git commits
+
+Please configure Git to use your real first and last name for any commits you intend to submit as pull requests. Make sure the name is properly capitalized as submitted to the https://cla.pivotal.io[Pivotal Contributor License Agreement]:
+
+----
+First Last <user@mail.com>
+----
+
+This helps ensure traceability against the CLA, and also goes a long way to ensuring useful output from tools like Git shortlog and others.
+
+You can configure this globally:
+
+----
+git config --global user.name "First Last"
+git config --global user.email user@example.com
+----
+
+or locally for the current repository by omitting the `--global` flag:
+
+----
+git config user.name "First Last"
+git config user.email user@example.com
+----
+
+= Format commit messages
+
+. Keep the subject line to 50 characters or less if possible
+. Do not end the subject line with a period
+. In the body of the commit message, explain how things worked before this commit, what has changed, and how things work now
+. Include `Closes gh-<issue-number>` at the end if this fixes a GitHub issue
+. Avoid markdown, including back-ticks identifying code
+
+Example:
+
+----
+Short (50 chars or less) summary of changes
+
+More detailed explanatory text, if necessary.  Wrap it to about 72
+characters or so.  In some contexts, the first line is treated as the
+subject of an email and the rest of the text as the body. The blank
+line separating the summary from the body is critical (unless you omit
+the body entirely); tools like rebase can get confused if you run the
+two together.
+
+Further paragraphs come after blank lines.
+
+ - Bullet points are okay, too
+
+ - Typically a hyphen or asterisk is used for the bullet, preceded by a
+   single space, with blank lines in between, but conventions vary here
+
+Closes gh-123
+----
+
+
+= Run all tests prior to submission
+
+----
+./gradlew clean build integrationTest
+----
+
+= Submit your pull request
+
+*Subject line:*
+
+Follow the same conventions for pull request subject lines as mentioned above for commit message subject lines.
+
+*In the body:*
+
+. Explain your use case. What led you to submit this change? Why were existing mechanisms in the framework insufficient? Make a case that this is a general-purpose problem and that yours is a general-purpose solution, etc
+. Add any additional information and ask questions; start a conversation, or continue one from GitHub Issues
+. Mention any GitHub Issues
+. Also mention that you have submitted the CLA as described above
+Note that for pull requests containing a single commit, GitHub will default the subject line and body of the pull request to match the subject line and body of the commit message. This is fine, but please also include the items above in the body of the request.
+
+= Mention your pull request on the associated GitHub issue
+
+Add a comment to the associated GitHub issue(s) linking to your new pull request.
+
+= Expect discussion and rework
+
+The Spring team takes a very conservative approach to accepting contributions to the framework. This is to keep code quality and stability as high as possible, and to keep complexity at a minimum. Your changes, if accepted, may be heavily modified prior to merging. You will retain "Author:" attribution for your Git commits granted that the bulk of your changes remain intact. You may be asked to rework the submission for style (as explained above) and/or substance. Again, we strongly recommend discussing any serious submissions with the Spring Framework team prior to engaging in serious development work.
+
+Note that you can always force push (`git push -f`) reworked / rebased commits against the branch used to submit your pull request. i.e. you do not need to issue a new pull request when asked to make changes.

-[#update-dependencies]
-== Update dependencies
-
-Dependency versions are managed in the file xref:./gradle/libs.versions.toml[libs.versions.toml] and are automatically updated by xref:./.github/dependabot.yml[dependabot].
-
-[#check-all-issues-are-closed]
-== Check all issues are closed
-
-The first step of a release is to check if there are any open issues remaining in a milestone.
-
-NOTE: A scheduled release will not proceed if there are any open issues.
-
-TIP: If you need to prevent a release from occurring automatically, the easiest way to block a release is to add an unresolved issue to the milestone.
-
-The https://github.com/spring-io/spring-security-release-tools/blob/main/release-plugin/README.adoc#checkMilestoneHasNoOpenIssues[`checkMilestoneHasOpenIssues`] command will check if there are any open issues for the release.
-Before running the command manually, replace the following values:
-
-* `<next-version>` - Replace with the title of the milestone you are releasing now (i.e. 5.5.0-RC1)
-* `<github-personal-access-token>` - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `public_repo`. This is optional since you are unlikely to reach the rate limit for such a simple check.
+Ensure you have no changes in your local repository.
+Change to a new branch.
+For example:
 
 [source,bash]
 ----
-./gradlew checkMilestoneHasOpenIssues -PnextVersion=<next-version> -PgitHubAccessToken=<github-personal-access-token>
+$ git checkout -b 5.5.0-RC1-dependencies
 ----
 
-Alternatively, you can manually check using the https://github.com/spring-projects/spring-security/milestones[milestones] page.
+Review the rules in build.gradle to ensure the rules make sense.
+For example, we should not allow major version updates in a patch release.
+Also ensure that all of the exclusions still make sense.
 
-[#update-release-version]
-== Update release version
-
-If all issues for the release are <<check-all-issues-are-closed,closed>>, the version number is automatically updated using the milestone title.
-When performing this step manually, update the version number in `gradle.properties` for the release (for example `5.5.0`) and commit the change using the message "Release x.y.z".
-
-[#tag-release]
-== Tag release
-
-The release will automatically be tagged using the milestone title.
-It is not required to tag manually.
-However, you can perform this step manually by running the following command:
+The following Gradle command will update your dependencies creating a commit for each dependency update.
+The first invocation of the command will take quite a while (~20 minutes depending on internet speed) to run because it is indexing all the versions of all the dependencies.
 
 [source,bash]
 ----
-git tag 5.5.0
+$ ./gradlew updateDependencies
 ----
 
-[#push-release-commit]
-== Push release commit
-
-During a scheduled release, the release commit will automatically be pushed to trigger a build.
-If performing this step manually, you can push the commit and tag and GitHub actions will build and deploy the artifacts with the following command:
+Review the commits to ensure that the updated dependency versions make sense for this release. For example, we should not perform a major version update for a patch release.
 
 [source,bash]
 ----
-git push --atomic origin main 5.5.0
+$ git log
 ----
 
-The build will automatically wait for artifacts to be released to Maven Central.
-You can get notified manually when uploading is complete by running the following:
+If any of the versions don’t make sense, update `build.gradle` to ensure that the version is excluded.
+
+Run all the checks:
 
 [source,bash]
 ----
-./scripts/release/wait-for-done.sh 5.5.0
+$ ./gradlew check
 ----
 
-[#build-locally]
-== Build
+If they don’t work, you can run a git bisect to discover what broke the build.
+Fix any commits that broke the build.
 
-All checks will automatically be performed by the build prior to uploading the artifacts to Maven Central.
-If something goes wrong, you can run the build locally using:
+Check out the original brach:

-[#update-release-notes-on-github]
-== Update release notes on GitHub
+The following command will update the dependencies again but this time creating a ticket for each update and placing `Closes gh-<number>` in the commit. Replacing the following values:
 
-Once the release has been uploaded to Maven Central, release notes will automatically be generated and a GitHub release will be created.
-To do this manually, you can use the https://github.com/spring-io/spring-security-release-tools/blob/main/release-plugin/README.adoc#generateChangelog[`generateChangelog`] command to generate the release notes by replacing:
-
-* `<next-version>` - Replace with the milestone you are releasing now (i.e. 5.5.0)
+* <github-personal-access-token> - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `public_repo`
+* <next-version> - Replace with the title of the milestone you are releasing now (i.e. 5.5.0-RC1)
 
 [source,bash]
 ----
-./gradlew generateChangelog -PnextVersion=<next-version>
+$ ./gradlew updateDependencies -PupdateMode=GITHUB_ISSUE -PgitHubAccessToken=<github-personal-access-token> -PnextVersion=<next-version>
 ----
 
-Then copy the release notes to your clipboard (your mileage may vary with the following command):
+Apply any fixes from your previous branch that were necessary.
+
+= Check All Issues are Closed
+
+The following command will check if there are any open issues for the ticket.
+Before running the command, replace the following values:
+
+* <github-personal-access-token> - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `public_repo`. This is optional since you are unlikely to reach the rate limit for such a simple check.
+* <next-version> - Replace with the title of the milestone you are releasing now (i.e. 5.5.0-RC1)

-Finally, create the
-https://github.com/spring-projects/spring-security/releases[release on
-GitHub], associate it with the tag, and paste the generated notes.
+Alternatively, you can manually check using https://github.com/spring-projects/spring-security/milestones
 
-Alternatively, you can run the https://github.com/spring-io/spring-security-release-tools/blob/main/release-plugin/README.adoc#createGitHubRelease[`createGitHubRelease`] command to perform these steps automatically, replacing:
+= Update Release Version
 
-* `<next-version>` - Replace with the milestone you are releasing now (i.e. 5.5.0)
-* `<branch>` - The name of the branch to be tagged (if the release commit has not already been tagged)
-* `<github-personal-access-token>` - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `write:org`
+Update the version number in `gradle.properties` for the release, for example `5.5.0-M1`, `5.5.0-RC1`, `5.5.0`
+
+= Update Antora Version
+
+You will need to update the antora.yml version.
+If you are unsure of what the values should be, the following task will instruct you what the expected values are:

-
-* `<next-version>` - Replace with the milestone you are releasing now (i.e. 5.5.0)
-* `<previous-version>` - Replace with the previous release which will be removed from the listed versions (i.e. 5.5.0-RC1)
-* `<github-personal-access-token>` - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `read:org` as https://spring.io/restdocs/index.html#authentication[documented for spring.io api]
+Run the build using
 
 [source,bash]
 ----
-./gradlew createSaganRelease deleteSaganRelease -PnextVersion=<next-version> -PpreviousVersion=<previous-version> -PgitHubAccessToken=<github-personal-access-token>
+$ ./gradlew check
 ----
 
-Alternatively, you can log into Contentful and update the versions manually on the Spring Security project page.
+= Push the Release Commit
 
-[#close-create-milestone]
-== Close / Create milestone
+Push the commit and GitHub actions will build and deploy the artifacts
+If you are pushing to Maven Central, then you can get notified when it’s uploaded by running the following:
 
-The release milestone will be automatically closed once the release is complete.
-To proceed manually, perform the following steps:
+[source,bash]

-NOTE: Remember that scheduled releases <<check-all-issues-are-closed,will not proceed>> if there are still open issues in the milestone.
-
-[#announce-release-on-slack]
-== Announce release on Slack
-
-The release will automatically be announced on Slack.
-If proceeding manually, announce the release on Slack in the channel https://pivotal.slack.com/messages/spring-release[#spring-release], including the keyword `+spring-security-announcing+` in the message.
+* Announce via Slack on

+== 7. Update to Next Development Version
 
-[[frequently-asked-questions]]
-== Frequently Asked Questions
+* Update `gradle.properties` version to next `+SNAPSHOT+` version, update antora.yml, and then push
 
-*When should I update dependencies manually?* Dependencies should be updated at the latest the end of the week prior to the release. This is usually the Friday following the 2nd Monday of the month (counting from the first week with a Monday). When in doubt, check the https://github.com/spring-projects/spring-security/milestones[milestones] page for release due dates.
+== 8. Update version on project page
 
-*When do scheduled releases occur?* Automated releases are scheduled to occur at *3:15 PM UTC* on the *3rd Monday of the month* (counting from the first week with a Monday).
+The following command will update https://spring.io/projects/spring-security#learn with the new release version using the following parameters
 
-[NOTE]
-The scheduled release process currently runs every Monday but only releases when a release is due. See the performed checks below for more information.
+<github-personal-access-token> - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `read:org` as https://spring.io/restdocs/index.html#authentication[documented for spring.io api]
+<next-version> - Replace with the milestone you are releasing now (i.e. 5.5.0-RC1)
+<previous-version> - Replace with the previous release which will be removed from the listed versions (i.e. 5.5.0-M3)
 
-The automated release process occurs on the following branches:
+[source,bash]
+----
+$ ./gradlew saganCreateRelease saganDeleteRelease -PgitHubAccessToken=<github-personal-access-token> -PnextVersion=<next-version> -PpreviousVersion=<previous-version>
+----
 
-* `main`
-* `6.2.x`
-* `6.1.x`
-* `6.0.x` (commercial only)
-* `5.8.x`
 
-For each of the above branches, the automated process performs the following checks before proceeding with the release:
 
-1. _Check if the milestone is due today._ This check compares the current (SNAPSHOT) version of the branch with available milestones and chooses the first match (sorted alphabetically). If the due date on the matched milestone is *not* today, the process stops.
-2. _Check if all issues are closed._ This check uses the milestone from the previous step and looks for open issues. If any open issues are found, the process stops.
+== 9. Update Release Notes on GitHub
 
-[IMPORTANT]
-You should ensure all issues are closed or moved to another milestone prior to a scheduled release.
+Generate the Release Notes replacing:
 
-If the above checks pass, the version number is updated (in `gradle.properties`) and a commit is pushed to trigger the CI process.
+* <next-version> - Replace with the milestone you are releasing now (i.e. 5.5.0-RC1)
 
-*How do I trigger a release manually?* You can trigger a release manually in two ways:
+----
+$ ./gradlew generateChangelog -PnextVersion=<next-version>
+----
 
-1. Trigger a release for a particular branch via https://github.com/spring-projects/spring-security/actions/workflows/update-scheduled-release-version.yml[`update-scheduled-release-version.yml`] on the desired branch. The above checks are performed for that branch, and the release will proceed if all checks pass. _This is the recommended way to trigger a release that did not pass the above checks during a regularly scheduled release._
-2. Trigger releases for all branches via https://github.com/spring-projects/spring-security/actions/workflows/release-scheduler.yml[`release-scheduler.yml`] on the `main` branch. The above checks are performed for each branch, and only releases that pass all checks will proceed.
+* Copy the release notes to your clipboard (your mileage may vary with
+the following command)
+
+....
+cat build/changelog/release-notes.md | xclip -selection clipboard
+....
+
+* Create the
+https://github.com/spring-projects/spring-security/releases[release on
+GitHub], associate it with the tag, and paste the generated notes
+
+== 10. Close / Create Milestone
+
+* In
+https://github.com/spring-projects/spring-security/milestones[GitHub
+Milestones], create a new milestone for the next release version
+* Move any open issues from the existing milestone you just released to
+the new milestone
+* Close the milestone for the release.
+
+== 11. Announce the release on other channels
+
+* Create a https://spring.io/admin/blog[Blog]
+* Tweet from [@SpringSecurity](https://twitter.com/springsecurity)
 
-*When should additional manual steps be performed?* All other automated steps listed above occur during the normal CI process. Additional manual steps can be performed at any time once the builds pass and releases are finished.
 
-*What if something goes wrong?* If the normal CI process fails, you can retry by re-running the failed jobs with the "Re-run failed jobs" option in GitHub Actions. If changes are required, you should revert the "Release x.y.z" commit, delete the tag, and proceed manually.
