# Pushing a New Version
|
|
Nunjucks attempts to adhere to semantic versioning. The API is very stable, so
|
from here on out it will most likely be point releases.
|
|
1. Do a `pull` from github to make sure you have all the latest updates.
|
|
2. View all the changes since the last version:
|
|
```
|
$ git log --oneline v1.2.3..master
|
```
|
|
Replace `v1.2.3` with whatever the last version was, and you'll see all the
|
changes going out in this version. Ensure that all significant user-facing
|
changes (new features and bugfixes) are mentioned in `CHANGELOG.md`. Change the
|
"master (unreleased)" heading in `CHANGELOG.md` to the new version number and
|
date.
|
|
3. Update the version in `package.json`.
|
|
3. Run the command to update the ready-made files for the browser.
|
|
```
|
$ npm run browserfiles
|
```
|
|
5. Commit above changes and push to `master` (or a release branch, if using one).
|
|
6. Draft a new release on GitHub and copy the changelog to the description. The
|
tag and title should both be the version, in the form `v2.3.0`. Publish the
|
release.
|
|
7. Publish to npm:
|
|
```
|
npm publish
|
```
|
|
8. Make sure docs are up-to-date. You need to copy all the `nunjucks*.js` files
|
in `browser/` to the docs. This is where the "download" link points to in
|
the docs. You also need to copy the tests into the docs, for the online
|
browser tests. ``make prod`` in the ``docs/`` dir will handle these tasks
|
for you. Push (force push if necessary) the build out _site folder onto the
|
`gh-pages` branch of the `nunjucks` repo to get it live. One way to do that
|
is the following commands. These commands presume that you have another
|
nunjucks git clone inside the (git-ignored) `docs/_site` directory, checked
|
out to the `gh-pages` branch (and tracking `origin/gh-pages`). (To set that
|
up the first time, `cd docs/_site`, `rm -rf *`, `git clone
|
git@github.com:mozilla/nunjucks.git .`, and `git checkout gh-pages`).
|
|
```
|
cd docs && make prod
|
cd files
|
python -m SimpleHTTPServer
|
# load http://localhost:8000/tests/browser/ and verify tests pass in browser
|
cd ../_site && git add -A && git commit && git push
|
```
|
|
9. Add a new "master (unreleased)" section at the top of `CHANGELOG.md`.
|
|
10. Bump the version number in `package.json` to a development pre-release of
|
the next anticipated release number (e.g. "2.2.0-dev.1").
