+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [5.4.0] - 2024-01-31
+
+### Changed
+- Updated to Node.js v20 runtime
+- Updated all dependencies to latest versions
+
+## [5.3.0] - 2023-09-30
+
+### Added
+- **Branch-based versioning mode** (`version_from_branch` input) - Major/minor versions can now be derived from branch names (e.g., `release/v1`, `release/1.2`). Only considers tags matching the branch version, useful for maintaining multiple release lines
+- Enhanced diagnostics documentation in contributing guide
+- Improved warning messages to clarify when no tags are found vs when tags exist but don't match criteria
+
+### Fixed
+- `GITHUB_REF_NAME` environment variable no longer causes failures during testing
+- `bump_each_commit` now properly respects `enable_prerelease_mode` setting
+- Non-version branches are properly ignored when using branch-based versioning
+
+### Changed
+- Updated Jest configuration for better test isolation
+- Rebuilt distribution files with latest changes
+
+### Deprecated
+- `use_branches` input is deprecated and will be removed in v6.0.0 - use `version_from_branch` instead
+
+## [5.2.1] - 2023-08-24
+
+### Fixed
+- Diagnostic mode output was not being properly included in the action's output, preventing debugging
+
+## [5.2.0] - 2023-08-20
+
+### Added
+- **Debug/diagnostic mode** (`debug` input) - Captures and outputs diagnostic information for troubleshooting version calculations. Useful when the source repository isn't available for direct inspection
+
+## [5.1.0] - 2023-08-09
+
+### Added
+- **Patch pattern filtering** (`bump_each_commit_patch_pattern` input) - When using `bump_each_commit`, patch version only increments if commit matches specified pattern. Supports JavaScript regex syntax with flags (e.g., `/fix\(.*\)/i`)
+- **Pre-release mode** (`enable_prerelease_mode` input) - Prevents automatic major version bumps for 0.x.x versions. When enabled, "major" changes become "minor" and "minor" become "patch", preventing premature 1.0.0 releases
+- `is_tagged` output - Boolean indicating if the current commit already has a version tag
+- Previous version commit information outputs (`previous_commit`, `previous_version`) for better version tracking
+
+### Fixed
+- Corrected tag ordering when determining previous version (was using reverse order incorrectly)
+- Increased test timeout for Windows environments to prevent CI failures
+- Fixed test failures in environments with global GPG signing enabled
+- Documentation typo: "version" output name was incorrectly documented
+
+## [5.0.3] - 2023-01-10
+
+### Fixed
+- Pre-release tags on current commit were not being handled correctly when determining version increments
+- Fixed incorrect parameter name mapping that was causing action failures
+
+### Changed
+- Updated dependencies to latest versions
+
+## [5.0.2] - 2022-12-31
+
+### Fixed
+- Build output mapping was incorrect, causing the action to fail when generating outputs
+
+## [5.0.1] - 2022-12-27
+
+### Fixed
+- Tag prefix and namespace values are now properly escaped when constructing regex patterns, preventing regex errors with special characters
+- Fixed unescaped dots in regex patterns that could cause incorrect matching
+- Test suite now consistently uses 'master' as branch name to avoid CI failures
+
+### Added
+- Syntax highlighting for code examples in documentation
+- Contributing.md guide for developers
+- Test coverage for namespaces containing forward slashes
+
+### Changed
+- Documentation updated to reflect correct input parameter names
+- Version calculation no longer limits the number of tags retrieved, ensuring accurate version determination in repos with many tags
+
+## [5.0.0] - 2022-12-20 - Major Rewrite
+
+### Added
+- **Complete TypeScript rewrite** - Action rewritten from JavaScript to TypeScript with modular architecture
+- **Author tracking** - New `authors` output lists all commit authors since last release, formatted as CSV (JSON option available via `user_format_type`)
+- **Commit body searching** - `search_commit_body` input allows searching commit message bodies for version patterns, not just the subject line
+- **Branch support** - Can now use branch names instead of tags for versioning with `use_branches` input
+- **Improved outputs** - Additional metadata including `version_type`, commit hashes, and more detailed version information
+- **Namespace support without tags** - Namespaces now work even when no existing tags match the namespace
+
+### Fixed
+- Pre-release tags (alpha, beta, rc) are now properly excluded from version calculations unless explicitly included
+- Fixed issue where current commit's tag wasn't properly considered when calculating previous version
+- Tag ordering now uses git's version sort instead of author date, providing more accurate version ordering
+
+### Changed
+- Architecture completely redesigned with providers, resolvers, classifiers, and formatters for better extensibility
+- Short tag support has been completely removed (was deprecated in v4)
+- Updated to actions/core@1.10.0 and modernized all dependencies
+- Node.js 16 compatibility
+
+## [4.0.3] - 2021-10-29
+
+### Changed
+- Version output now properly uses the user-supplied version format template combined with namespace
+- Updated dependencies and improved test coverage
+- Documentation clarifications for better user understanding
+
+## [4.0.2] - 2021-04-22
+
+### Fixed
+- Tag prefixes can now contain forward slashes (e.g., `releases/v`), enabling more flexible tagging schemes
+
+## [4.0.1] - 2021-02-25
+
+### Fixed
+- Fixed regex pattern for matching full version tags when `short_tags` is disabled
+
+## [4.0.0] - 2021-02-08
+
+### Changed
+- **Breaking**: Branch parameter now defaults to `HEAD` instead of requiring explicit branch name
+- Branch names no longer include `origin/` prefix, simplifying branch-based versioning
+- Reintroduced support for using `HEAD` as branch parameter (was removed in v3)
+
+### Deprecated
+- `branch` input is now deprecated in favor of automatic HEAD detection
+
+## [3.3.1] - 2021-01-28

+
+### Fixed
+- Fixed logic that prevented version tags from being properly matched when calculating increments
+
+## [3.2.1] - 2021-01-16
+
+### Fixed

+- SVG diagrams now have proper background color for better visibility
+
+### Changed
+- Updated dependencies
+- Documentation improvements
+
+## [3.2.0] - 2020-12-20
+
+### Added
+- **`bump_each_commit` mode** - Every commit creates a new patch version, useful for continuous deployment scenarios
+- **`short_tags` toggle** - When set to `false`, only full semantic version tags (e.g., v1.2.3) are considered, ignoring short tags (e.g., v1)
+
+### Changed
+- Improved documentation with visual diagrams
+- Removed deprecated parameters from documentation
+- Enhanced readme clarity with better examples
+
+## [3.1.2] - 2020-10-07
+
+### Fixed
+- **Full Windows support** - Fixed line ending issues and command execution on Windows
+- Action now properly exits when current commit already has a version tag
+- Current commit's tag is now used as the version when applicable
+
+### Added

+- **Namespace support** (`namespace` input) - Enables multiple projects/components in same repo with isolated versioning
+- **Improved mono-repo support** - Each namespace maintains its own version sequence
+
+### Changed
+- **Breaking**: `change_path` input now filters which paths trigger version changes rather than just detecting changes
+- Removed verbose action output for cleaner logs
+- Modernized codebase and dependencies for GitHub Actions runner compatibility
+
+### Removed
+- Deprecated action inputs from v2
+
+## [2.1.1] - 2020-02-07

+# Contributing
+
+Fixes and enhancements are welcome, but if you are planning to do a lot of work, it is a good idea to raise an issue first to discuss it. Generally enhancements should follow the goals of the project described in the main readme:
+
+- Allow the version to be injected into the build
+- Derive the version only from the git repository itself
+- Do not require the version to be maintained by hand
+- Resolve the version deterministically for a given commit
+- Provide an easy mechanism for incrementing major and minor versions by developers
+
+## Getting Help
+
+If you have found or believe you have found a bug please open a ticket. If you are having trouble using the action and need help please use the discussions page.
+
+Since nearly all questions are related to a specific repository it can be difficult to diagnose issues from a description alone. There are a few ways to provide additional information that can help diagnose the problem.
+
+### Creating Diagnostic Information
+
+There is a debug option which produces diagnostic information. This information can be used to troubleshoot and even to rerun the action without access to the original repository, for example with a debugger attached. To enable this option set the `debug` input to `true` and then use the `debug_output` output to access the information. The following configuration will print the debug output to the console:
+
+```
+- name: Version
+  uses: paulhatch/semantic-version@v5.4.0
+  id: version
+  with:
+    tag_prefix: ""
+    version_format: "${major}.${minor}.${patch}.${increment}"
+    debug: true
+
+- name: Print Diagnostic Output
+  run: echo "$DEBUG_OUTPUT"
+  env:
+    DEBUG_OUTPUT: ${{ steps.version.outputs.debug_output }}
+```
+
+Please review the information before posting it to avoid disclosing any sensitive information. In particular the output may contain names and email addresses of the committers, as well as commit messages for recent commits.
+
+### Providing a Test Case
+
+If you are planning to open a ticket or post to discussions, it is extremely helpful if you can provide a test case that demonstrates the problem. This project includes a test helper than makes it very easy to create new tests with just a few lines of code.
+
+To get started simply:
+
+- Ensure you have the latest version of NodeJS installed (https://nodejs.org)
+- Clone the repository, `git clone https://github.com/PaulHatch/semantic-version.git` or `git@github.com:PaulHatch/semantic-version.git`
+- Run `npm install` in the root of the repository to install the dependencies
+- Run `npm run test` to run the tests
+
+The src/main.test.ts file contains integration tests that validate all the features of this action, to add a new test case simply add a new function to the bottom of this file.
+
+```typescript
+test('Name of test goes here', async () => {
+    // This method creates a test repository in your temp directory, the repo
+    // object returned provides methods to interact with the repository
+    const repo = createTestRepo({
+        // Specify any config options you want to set, the options available can be found
+        // in the src/ActionConfig.ts file
+        tagPrefix: ''
+    });
+
+    // the make commit method creates a commit with the specified message, an empty file will be
+    // automatically created for the commit
+    repo.makeCommit('Initial Commit');
+
+    // an optional second parameter can be used to specify the path of the file to commit,
+    // which will be created if it does not exist already
+    repo.makeCommit('Initial Commit', 'subdir');
+    
+    // the exec method runs an arbitrary command in the repository
+    repo.exec('git tag 0.0.1')
+
+    // the runAction method runs the action and returns the result
+    const result = await repo.runAction();
+
+    // finally, the use whatever assertion you want to validate the result
+    expect(result.formattedVersion).toBe('0.0.1+0');
+}, 15000);
+```
+
+This uses the [Jest](https://jestjs.io/) testing framework. Really it is generally not necessary to be very familiar with Jest, just copy the pattern of the existing tests and you should be fine.
+
+Once you have a failing test case that demostrates the problem, you can just past it into the ticket, there is no need to create a repository unless you want to.
+
+
+### Providing an Example Repository
+
+If you are not able to provide a test case, it is still very helpful to provide an example repository that demonstrates the problem. Many times people are experiencing problems with a configuration of a private repository. This is quite difficult to debug without access to the repository, if you are able to provide a public repository that demonstrates the problem it will make it much easier to debug and can eliminate a great deal of back and forth.
+
+## Forking the Project
+
+If want to do something that does not fit with the project goals, particually if you want to include information from an outside system, it is probably best to fork the project and create your own action. One of the goals of this project starting in 5.0.0 is to be easy to fork and customize, and to that end the action has been broken into individual providers than can be replaced. All providers have been implemented using async calls specifically to support calls to external systems.
+
+The steps of this action are:
+
+- Get the current commit
+- Get the last release
+- Get commits between the last release and the current commit
+- Classify the release
+
+Additionally a few formatter provide modular behavior to these step:
+- A tag formmater is used to parse and format the version number
+- A version formatter is used to format output version string
+- A user formatter is used to format the user information in the output (JSON and CSV are provided in the default implementation)
+
+Each one includes at least one default, but can be replaced by a custom provider by implementing the appropriate interface and updating the `ConfigurationProvider` to return your action instead. This should allow you to continue to merge in changes from the main project as needed with minimal conflict.

+# Configuration Guide
+
+## Choosing a Release Strategy
+
+This section is designed to help you choose a release strategy for your project and help you configure GitHub Workflow to use that strategy. It is organized starting from the most simple with each strategy supporting more complex needs, allowing you to start at the top and continue until you find the simplest strategy that meets your needs.
+
+Note that in the examples given `latest` is used, but you will likely want to pin your version to a specific version.
+
+### Increment Every Release
+
+If your project has no gating requirements and you want to release every time a commit is pushed to the default branch, you can use the _Increment Every Release_ strategy. This may be appropriate for documentation projects, very small projects, or in cases where "shipping" a broken version isn't a big deal. The key limitation of this strategy is that once you push a commit, the version is going to increments no matter what. If you push a version and your build or automated tests fail, you'll have a version that is broken and you'll have to increment the version again to fix it.
+
+```yaml
+- uses: paulhatch/semantic-version@latest
+  with:
+    bump_each_commit: true
+```
+
+### Increment from Commit Message
+
+Very similar to the strategy above, using the _Increment from Commit Message_ means that you are making the decision to increment the version at the time you commit the code, however by using the `bump_each_commit_patch_pattern` parameter introduced in v5.1.0, you can prevent the version from incrementing for a commit unless it matches one of the patters (major, minor, or patch).
+
+Compared to the _Increment Every Release_ strategy, this strategy allows you to make a decision about whether or not to increment the version for a particular commit, allowing you to add commits to a repo that do not increment the version. Again, you make the decision to increment the version at the time you commit the code, so this strategy may not be appropriate for some project types.
+
+On the other hand, if you have a fast deployment strategy, such as "every commit goes to prod" and don't mind versions being created for failed builds, this may be the right choice.
+
+```yaml
+- uses: paulhatch/semantic-version@latest
+  with:
+    bump_each_commit: true
+    bump_each_commit_patch_pattern: "(PATCH)"
+```
+
+
+### Tag Versioning
+
+This strategy is the most common and is the best option for many projects. It allows you to make the decision to release a version after the build has run, which is essentially the primary motivation and main purpose for this action.
+
+The only real limitation of this strategy is that it does not allow for multiple versions to receive ongoing updates, which may be necessary for certain types of projects which are distributed and receive ongoing maintenance of older versions. This is in contrast to projects that are developed only for a single deployment and are not distributed.
+
+Tags should generally not be created automatically as part of the build, which can cause strange behavior unless you've taken care to prevent race conditions. Creating tags automatically also largely negates the purpose of this strategy.
+
+_This is the default behavior, so no special options are required._
+
+```yaml
+- uses: paulhatch/semantic-version@latest
+```
+
+
+### Branch + Tag Versioning
+
+So far all the options considered have assumed that a single, ever incrementing version is being released, and that once a new major or minor version is tagged no further updates are made for previous versions. This is appropriate for many projects such as web applications and most libraries, however if you need to support on-going update to multiple major or major+minor versions, using only the approaches above can lead to problems if you are merging updates into multiple branches, as any tags may be picked up and cause the version of an older branch to unexpectedly jump.
+
+To accomplish this, we can enable the `version_from_branch`, which will cause the major and optionally the minor version to be taken from the current branch name rather than the tag, and to filter out tags that do not begin with the same version number(s). The `version_from_branch` input can be either a boolean or a regex string to be used to identify the version from the branch name. By default this will be `[0-9]+.[0-9]+$|[0-9]+$` e.g. match the final number or pair of numbers separated by a `.`. This default is probably appropriate for the majority of cases as it will match any prefix, for example branches named:
+
+- `release/v1`
+- `release/v1.2`
+- `v1`
+- `v1.2`
+- `1`
+- `1.2`
+
+Note that when using this strategy you should always tag at the same time as the branch is created to ensure that the increment value is correct.
+
+```yaml
+- uses: paulhatch/semantic-version@latest
+  with:
+    version_from_branch: true
+```
+
+Alternately, you can override the branch pattern.
+
+```yaml
+- uses: paulhatch/semantic-version@latest
+  with:
+    version_from_branch: "/v([0-9]+.[0-9]+$|[0-9]+)$/"
+```
+
+## Namespace Services / "Monorepo" Support
+
+If your project contains multiple services which you wish to version independently, you can use the `namespace` and `change_path` inputs to provide a version for a specific service which increments only when a file in the specified path is changed. (Or, if you are only build on push/pull requests you can just use the GitHub Action's [`paths`/`paths-ignore`](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#onpushpull_requestpull_request_targetpathspaths-ignore) feature to block the trigger itself and run the workflow only when files in a specific path are changed. In contrast this method will also work on other triggers like `workflow_dispatch`.)
+
+```yaml
+- id: version
+  uses: paulhatch/semantic-version@latest
+  with:
+    change_path: "src/my-service"
+    namespace: my-service
+- name: Cancel if Unchanged
+  if: ${{ ! fromJSON(steps.version.outputs.changed) }}
+  run: |
+    gh run cancel ${{ github.run_id }}
+    gh run watch ${{ github.run_id }}
+  env:
+    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+
+## Additional Configuration
+
+| Value | Description |
+| --- | --- |
+| `tag_prefix` | The prefix to use for the tag. Defaults to `v`, generally you will use either `v` or an empty string. Note that the tag format is distinct from the version. Tags used for versioning must always follow the pattern `{tag_prefix}{major}.{minor}.{patch}` with and optional `-{namespace}` suffix. |
+| `major_pattern` and `minor_pattern` | These strings are used to determine the type of version to create. If any commit message since matches the `major_pattern` the major version will be incremented, if it matches the `minor_pattern` the minor version will be incremented. If neither pattern matches, the patch version will be incremented. These can be specified either as strings or as regular expression by wrapping the expression in `/`. The defaults follow [Conventional Commits](https://www.conventionalcommits.org/): `/!:|BREAKING CHANGE:/` for major and `/feat:/` for minor. |
+| `version_format` | A value such as `${major}.${minor}.${patch}-prerelease${increment}` that will be used to format the version value of the output, **formatting this value is the only effect of this input parameter!** It is not used for parsing or any other purpose. It is a convenient alternative to formatting the output in a subsequent step. |
+| `user_format_type` | Indicates the format of the `authors` output. Can be `json` or `yaml`. |
+| `enable_prerelease_mode` | If true, major changes to versions starting with 0 will result in a minor change, preventing ths initial version `1.0.0`` from being created automatically by someone checking in a commit with the major pattern. |

 ![Build](https://github.com/PaulHatch/semantic-version/workflows/Build/badge.svg)

-> *Version 5-alpha now available!*
-> Version 5 adds support for several new features and allows easier extension/customization.
-> ##### Breaking Changes
-> - Versions now use the version number (`--sort=-v:*refname`) rather than date to determine which tag is the latest.
-> - "Short tag" support removed
->
-> See the [release notes](https://github.com/PaulHatch/semantic-version/releases/tag/v5.0.0-alpha) for more information.
+See the [configuration guide](guide.md) for help getting started, selecting a versioning strategy and example configurations, or [contributing.md](contributing.md) for information on how to get help or contribute to this project.

 - *version* is a formatted version string created using the format input. This is a convenience value to provide a preformatted representation of the data generated by this action.
 - *version_tag* is a string identifier that would be used to tag the current commit as the "released" version. Typically this would only be used to generate a Git tag name.
 - *changed* indicates whether there was a change since the last version if change_path was specified. If no `change_path` was specified this value will always be true since the entire repo is considered. (It is possible to create a commit with no changes, but the Git cli rejects this by default and this case is not considered here)

 - *authors* is a list of authors that have committed to this version, formatted as either csv or json.
+- *current_commit* is the current commit hash.
+- *previous_commit* is the previous commit hash.
+- *previous_version* is the previous version.
+- *debug_output* will show diagnostic information, if debug is enabled

 There are two types of "version" string, one is the semantic version output that can be used to identify a build and can include prerelease data and metadata specific to the commit such as `v2.0.1-pre001+cf6e75` (you would produce this string yourself using the version information from this action plus whatever metadata you wanted to add), the other is the tag version string, which identifies a specific commit as being a specific version.
