Bitbucket Data Center and Server 8.0 release notes

12 May 2022

We're excited to present Bitbucket Data Center and Server 8.0!

Highlights include:

If you’re upgrading from a version below 8.0, note that the upgrade process is standard and you don’t need to provision Bitbucket Mesh nodes unless you need faster Git processing and high availability of repositories.

Introducing Bitbucket Mesh


Large and busy Bitbucket Data Center instances can sometimes experience decreased Git performance because of the design of the shared file system. Bitbucket Mesh solves this problem. It is a horizontally scalable distributed Git storage that is purposely built for high Git performance and adds high availability to repositories.
By migrating your repositories from the shared file system to Mesh nodes, you’re moving the Git processing closer to the storage, which results in decreased I/O latency. As Mesh replicates your repositories on multiple Mesh nodes, your shared file system is no longer a single point of failure, and your instance becomes more resilient. Learn more about Bitbucket Mesh

Bitbucket DC 8.x with two cluster nodes and three Mesh nodes

Declutter unused repositories


Do you need to make a repository read-only to all users, but keep it available on your Bitbucket instance?

You can now archive a repository to let users know it’s no longer being maintained. When you archive a repository, it’s excluded from searches, and users can no longer move, comment, create pull requests or branches, and compare. If you’ve accidentally archived a repository or plan to maintain an archived repository later, you can unarchive it. Learn more about archiving repositories

Other improvements

Diff view updates


In 7.0, we redesigned pull requests and gave them a makeover. We’ve now moved all the diff views (including commit diffs, branch compares, and the Create Pull Request page) to the new format – enjoy a faster and consistent code collaboration experience!

If your app or integration uses frontend plugin points on these pages, refer to the API changes in the original pull request update.

SSH keys updates


We’ve updated SSH keys and Access keys pages with a fresh new look. To make sure your source code is secure, we now analyze your keys and highlight the ones that aren’t considered secure enough. If you use SSH keys to access Bitbucket Data Center or its integrations, we recommend that you use Ed25519 keys.

Build states


We’ve added two new build states, UNKNOWN and CANCELLED, that your Code Integration (CI) tool can send as build results:

UNKNOWN: indicates that the status of the build is not known.

CANCELLED: indicates that the build has been cancelled before it completed.

Updated VPAT documents for accessibility improvements


Continuing our investment in accessibility, we’ve refreshed the VPAT documents for our products to reflect recent improvements aligned with the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA.

Take a look at our VPAT documents for WCAG 2.1 and Section 508.

Connect to cloud products with secure application tunnels

Integrating Atlassian cloud and self-managed (Data Center and Server) products through application links requires opening your network for incoming connections, which isn’t something everyone can do. To solve this problem, we’re now introducing application tunnels.

Application tunnels use network tunneling to create a secure pathway between your organization in Atlassian Cloud and the products in your network. You can use this pathway to tunnel application links and integrate your products in a secure way. Thanks to that, your products can communicate with one another, while you keep your network safe and sound.

Application tunnels are available for Bitbucket 6.9 and later. Learn more about application tunnels

Before you upgrade to 8.0


We’ve ended Windows support

Bitbucket 7.21 is the last release that allowed you to host Bitbucket on Windows. Learn more about how to migrate Bitbucket Server from Windows to Linux

H2 database migration requirement

To achieve improved processing speeds, we’ve upgraded the H2 database to version 1.4.200 as it supports multithreading. Version 1.4.200 of H2 doesn’t support the PageStore format – if you’re using a H2 database for a Bitbucket Mirror or Server, you’ll need to migrate the on-disk database file to the MvStore format. Learn more about how to migrate your H2 database to the MvStore format

Minimum Git version

Bitbucket 8.0 will require Git 2.31 or higher. If your Bitbucket is on a lower version of Git, upgrade now.
