Based on our experience with our successful release candidates, we are confident to announce that Drupal 8.0.0 will be released on November 19, 2015! Until then, we will continue publishing Drupal 8 release candidates with the latest fixes. See the first release candidate announcement for more details on the release candidate phase, or download the latest release candidate (RC2) for a preview of the release.
Port your modules/themes and update translations
Preparing for release promotion
We are working on both the release announcement and the press release in English. However we do need volunteers to help translate it to their language. The final translations will be posted on Drupal.org at time of release.
If you can help promote the release on Twitter on November 19th and 20th in your respective time zones, Paul Johnson is looking for you. When tweeting about Drupal 8, be sure to use the hashtag #drupal8.
Parties around the globe!
We also need you to throw a party! Organize a local meetup on the week (or even better the exact date) with sweets, sessions, shirts, stickers or whatever fits to spice it up. Make sure to let the community know, so it shows up on the world map on Drupical.com We also suggest you follow @celebr8d8 and promote your party and share your party stories with #celebr8d8.
Finally, thanks to the nearly 3,300 people who contributed to the codebase of Drupal 8 as well as hundreds of others who organized events, conducted usability tests, mentored contributors, found sponsors, etc.—in short did all the awesome things that made Drupal 8 happen. Now, let’s go make something amazing, for anyone!
