Releasing

Release naming convention

Releases are named by the year and quarter when release is happening, e.g. January 2020 release is named 2020.1.X.

Bumping releases

We're using version-bump-prompt for increasing version.

Install version-bump-prompt via:

    npm install -g version-bump-prompt

If you would like to bump prepatch just type:

    bump --prepatch --tag --push

Distribute release

We have got configured CircleCI, TravisCI and AppVeyor for distributing application for particular platform. In order to release you need to tag&push your changes from master.

First of all please remove dev from version in package.json (for instance 2019.2.0-alpha.4dev to 2019.2.0-alpha.4). Commit & push changes with message Release 2019.2.0-alpha.4 . Next step is to tag repository and push to origin:

    git tag v2019.2.0-alpha.4
    git push origin v2019.2.0-alpha.4

When artifacts are made you can see draft release here: gns3-web-ui releases which is waiting to be published. After release please change current version in package.json to 2019.2.0-alpha.5dev'. Otherwise artifacts will be overwritten during the next commit. Don't forget to commit & push changes.

Updating gns3server

Checkout the latest master of gns3server. Run command ./scripts/update-bundled-web-ui.sh --tag=v2019.2.0-alpha.5. Commit & push changes with message Release 2019.2.0-alpha.4.

Staging release

In case you would like to create a new staging release. Please create draft release on github, like 0.0.1-dev1. After successful build you can find artifacts there.
