Better email notifications, right from the start
Back in Jira 8.0, we introduced batched email notifications that group all those little events occurring close together into summary emails, just to give your mailbox some breathing space. Now, after adding some improvements and letting you choose the frequency of summary emails, we’re making these notifications the default ones, for everybody. Learn more about notifications
An important note — batched notifications bring some changes for users who have customized how their notifications look. If you’re one of them, make sure to read all about it in our upgrade notes.
Filters in Multi User picker Custom field
In response to user requests, we've made it possible to limit the multi user picker custom field to hold only specific set of users. This is to prevent sending notifications to random users as a result of mistyping user names. This adds to the overall security of issues.
For more on the issue, see JRASERVER-36833.
External links open in a new tab
Now, you do not need to right-click every time you want an external link that's added to a Jira issue to open in a new tab in your browser. We've made this option default for external links. However, if you like all links to open in the same tab, you can easily change this in YourUserProfile > Profile > Preferences > External links.
Jira becomes more accessible
We’ve taken on the task of making Jira more compliant with the Voluntary Product Accessibility Template (VPAT) report that Atlassian released a few months back. To make it happen, we’ve fixed color contrast of inaccessible elements, added labels for UI elements to be picked up by screen readers, and made sure you can add comments with a keyboard shortcut.
Time tracking in bulk edit
Add time tracking information to issues when you edit them in bulk without using Jira REST API to do that. You can simply provide the Original and Remaining estimate when you edit multiple issues or when you resolve issues using bulk issue transition (and time tracking is on the resolution screen).
This is a great time saver as you do not need to correct or add time estimates by going through issues one by one.
Open links in your mobile app
To help you navigate between pages, you can go directly from a link, for example in an email notification, to the app. If you do not have the app yet, clicking the link will take you to the app download page in Play store (only for Android). Simply click the Open in app button that displays in mobile web.
Jira 
Docker
We’ve created official templates for deploying Jira Server and Data Center in a Docker container, joining the ranks of other Atlassian applications, like Confluence, Bamboo, or Bitbucket. Have a try and quickly spin a Jira instance with our template, or customize a Docker deployment on your own! The templates are available for Jira 8.0 and later. Learn more
New supported databases
We’re welcoming new databases to our family — Oracle 18c and 19c. Learn more
Additionally, we’re adding support for Aurora PostgreSQL for Jira Data Center.
