This action is confirmed to work on all three of GitHub's hosted runners -
ubuntu-latest
, macos-latest
and windows-latest

Maybe you don't want to checkout your code in the job that calculates the version number. That's okay, you can use the API mode:
- name: Get next version
uses: reecetech/version-increment@2024.4.3
id: version
with:
use_api: true
This action will detect the current latest normal semantic version (semver) from the tags in a git repository. It will increment the version as directed (by default: +1 to the patch digit). Both the current latest and the incremented version are reported back as outputs.
Normal semantic versions are made up of a major, minor and patch digit. Normal versions do not include pre-release versions, or versions with build meta-data.
e.g. 1.2.7
See: https://semver.org/spec/v2.0.0.html
Optionally, this action can provide semver compliant calendar versions (calver). In this calver scheme, the semver major, minor and patch digits map to year, month and release digits.
Note: to be semver compliant, digits must not have leading zeros.
e.g. 2021.6.2
semver | calver | example | note |
---|---|---|---|
major | year | 2021 |
|
minor | month | 6 |
|
patch | release | 2 |
The nth release for the month |
If the current latest normal version is not the current year and month, then the year and month digits will be set to the current year and month, and the release digit will be reset to 1.
If you choose the conventional commits scheme, the action will parse the last commit message (usually the merge commit) to determine
the increment type for a semver
version.
The following increment types by keyword are supported:
- patch: build, chore, ci, docs, fix, perf, refactor, revert, style, test
- minor: feat
- major: any of the above keywords followed by a '!' character, or 'BREAKING CHANGE:' in commit body
If none of the keywords are detected, then the increment specified by the increment
input will be used (defaults to patch).
Tip
You might like to enforce conventional commits in the title of your pull requests to ensure that the merge commit has the correct information. Something like this action might be handy: https://github.com/marketplace/actions/conventional-commit-in-pull-requests
Default branch
The action will return a normal version if it is detected that the current commit
is on the default branch (usually main
).
Examples:
1.2.7
2021.6.2
You may override the branch to consider the release branch if it is not the default branch, by providing a specific release branch name as an input. For example:
- name: Get next version
uses: reecetech/version-increment@2023.10.1
id: version
with:
release_branch: publish
Any other branch
The action will return a pre-release version if any other branch is detected
(e.g. new-feature
, bugfix/foo
, etc). The pre-release portion of the version number
will be the literal string pre.
followed by the git commit ID short reference SHA
(trimmed of any leading zeros).
Examples:
1.2.7-pre.41218aa78
2021.6.2-pre.32fd19841
name | description | required | default |
---|---|---|---|
scheme | The versioning scheme in-use, either semver , calver or conventional_commits |
No | semver |
pep440 | Set to true for PEP440 compatibility of pre-release versions by making use of the build metadata segment of semver, which maps to local version identifier in PEP440 |
No | false |
increment | The digit to increment, either major , minor or patch , ignored if scheme == calver |
No | patch |
release_branch | Specify a non-default branch to use for the release tag (the one without -pre) | No | |
use_api | Use the GitHub API to discover current tags, which avoids the need for a git checkout, but requires curl and jq |
No | false |
tag_prefix | Prefix the tag with a string (defaults to empty string). e.g. if set to @org/product/ the action will filter by this prefix and return @org/product/1.2.3 in prefixed-version output |
No |
name | description |
---|---|
current-version | The current latest version detected from the git repositories tags |
current-v-version | The current latest version detected from the git repositories tags, prefixed with a v character |
version | The incremented version number (e.g. the next version) |
v-version | The incremented version number (e.g. the next version), prefixed with a v character |
major-version | Major number of the incremented version |
minor-version | Minor number of the incremented version |
patch-version | Patch number of the incremented version |

patch-v-version | Patch number of the incremented version, prefixed with a v character |
prefixed-version | Incremented version calculated, including a tag_prefix if specified |
prefixed-v-version | Incremented version calculated, prefixed with a v charatcter, and also including a tag_prefix if specified |
