Cloning to your production site? Checkout the 2.1 branch! It's our vetted stable release.

Vanilla was born out of the desire to create flexible, customizable, and downright entertaining community solutions. Vanilla has been used to power tens of thousands of community forums around the world and we couldn't be happier if you've decided to use Vanilla to grow yours.

Every community is unique. Vanilla is a finely-crafted platform on which designers and developers can build a custom-tailored environment that meets your community's particular needs.

1. We've reimagined traditional forums for mass-appeal.
2. Our theming flexibility is second-to-none.
3. Impossibly good integration options with single sign-ons and embedding.
4. The best tools available for community management.
5. Curated features with great plugin options, not the kitchen sink.

Vanilla is free, open source software distributed under the GNU GPL2. We accept and encourage contributions from our community and sometimes give hugs in return. You can join us on the Vanilla Community Forums to be part of that discussion.

The latest stable release is always listed here. Currently, it is the 2.1 branch. We will support the 2.0 branch with security patches until the end of 2014.

New plugins and themes can be listed in the Official Addon Directory. We encourage addon developers to release their code under the GPL as well, but do not require it.

Vanilla Forums provides an official cloud hosting solution at vanillaforums.com with a 1-click install, automatic upgrades, amazing professional support, incredible scalability, integration assistance, theming and migration services, and exclusive features. For the very best Vanilla forum experience, you can skip the rest of this technical stuff and go there directly.

If you professionally run a large community or enterprise forum, our cloud solution will make the best technical and economic sense by far.

• PHP version 5.2 or newer with --enable-mbstring
• pdo_mysql module must be enabled
• MySQL 5 or newer

Vanilla 2.1 will be the last version to support PHP 5.2. PHP 5.4 or higher will be required in the future.

Vanilla ships with a .htaccess file for Apache support. Nginx and IIS require additional configuration.

On the client side, Vanilla should run & look good in just about any modern browser. Using IE? How exotic. You'll want IE8 or greater. IE7 might work if you squint hard and click gently, but we make no promises.

We've been natively mobile since before it was cool. Vanilla ships with a mobile-optimized theme enabled by default for all smartphones & tablets. Heck, it even works on the PlayStation Vita.

Vanilla is built to be simple, and its installation is no exception.

• Upload this entire file structure up to your web server.
• Confirm the cache, conf, and uploads folders are writable by PHP.
• Navigate to that folder in your web browser.
• Follow the instructions on screen.

Follow these steps to upgrade Vanilla when a new stable release is announced.

• Backup your database and conf/config.php file somewhere safe.
• Upload the new release's files so they overwrite the old ones.
• Go to yourforum.com/index.php?p=/utility/update to force any updates needed.
• If it fails, try it a second times by refreshing the page.

To upgrade to 2.1 from 2.0.18, add this step:

• Delete the file /themes/mobile/views/discussions/helper_functions.php

To upgrade from Vanilla 1.0, you must export your data using the Vanilla Porter as if it were a migration. Your theme and any customizations will need to be recreated. Backup your Vanilla 1 data and files completely, then delete them from your server before attempting to install Vanilla 2.

• Get Vanilla Porter and verify it supports your platform.
• Read the Advanced Uses notes on that page.
• Upload it to your current server.
• Navigate to the file in your web browser & run it.
• Take the file it produces and import it to Vanilla.

• Troubleshooting upgrades & installs
• Official documentation
• Vanilla community forums
• Official cloud hosting with professional support & migration services

• Troubleshoot issues you run into on the community forum so everyone can help & reference it later.
• Got an idea or suggestion? Use the forum to discuss it.
• File detailed issues on GitHub (version number, what you did, and actual vs expected outcomes).
• Sign the Contributors' Agreement to send us code.
• Use pull requests against the correct release.

We've adopted the git flow branching model in our projects. The creators of git flow released a short intro video to explain the model.

The master branch is production-ready for a our cloud product but is not yet vetted for open source release. Only small patches and hotfix/x branches land against master, and it always has a stable version number. The develop and stage branches are pre-production and are where we land feature/x branches for integration testing.

Our open source release branches are named by version number, e.g. 2.0 and 2.1. We begin release branches with a beta (b1) designation and progress them thru release candidate to stable. All open source releases (included pre-releases) are tagged.

After 2.1, we will be leap-frogging version numbers between master and releases. Releases will receive the next odd-point number and master will then jump to the next even-point number. Therefore, the next open source release after 2.1 will be 2.3. When the 2.3 beta begins, master will move to 2.4.
