 Upgrade notes

Known issue: Sprint suggestions aren’t working

The Sprint picker field (used either when creating/editing issues or searching for sprints) suggests the last five sprints you viewed. If you haven’t viewed at least five, Jira will retrieve all existing sprints and calculate which are the best suggestions for you. Because of a bug, Jira isn’t retrieving additional sprints, so you’re seeing suggestions that are based only on your history.

More about this problem: https://jira.atlassian.com/browse/JSWSERVER-20679

Affected versions: 8.11.x, 8.12.x, 8.13.0

Fixed versions: 8.13.1+, 8.14.0+ (not released yet)

Workaround: The only workaround right now is building your history so Jira can show suggestions based on it. To do this, you have to visit backlogs that include sprints you’re interested in. Follow this bug for updates

Note: Upgrading to one of the fixed versions might cause performance issues in large Jira instances with thousands of sprints. See Sprint picker field might cause performance issues

Support for Microsoft Exchange Online POP3 (8.13.1+)

We are planning to add the option to integrate with OAuth 2.0 using POP3 for Microsoft Exchange Online. The support will cover OAuth 2.0 integration for incoming mail. 

Document based replication

Our previous architecture meant that the speed of index replication across the cluster was limited by the slowest node in the cluster due to single thread replay of all indexing operations. This is no longer the case as index changes on a node are now sent to other nodes directly. So each node we add to the cluster increases the write capacity of the cluster.

With Jira DC 8.13, our new architecture means that the index replication will not be delayed & index will remain consistent across the cluster. Simply put, this means a more stable cluster and reliable consistency of data across each node in the cluster.

However, these architectural changes require each node to communicate directly with other nodes, which can double the network traffic. When testing this on a 8 node cluster running a sustained stress load of 400 requests per second, the total network traffic volume amounted to 25% of total capacity of a 1Gbps link. Traffic will be lower if the load or cluster size is lower.

For more on Document-based replication, see Document-based replication in Jira Data Center.

Setting to prevent phishing attacks 

To prevent non-authenticated users from navigating to crafted URLs in Jira and injecting messages onto the page, we've added a setting that disables displaying URL parameters in security dialogs. 

The setting is available in Jira administration > System > General configuration and defaults to Off

If the setting is disabled, the URL parameters that might be added to a URL are not captured and displayed in security dialogs. In that case, a security dialog looks the following:

New system property to speed up database search

We're introducing a new mechanism that retrieves custom field values for issues in batches of 50. This speeds up time-consuming operations such as database search. 

For now, all these improvements affect only Jira built-in custom fields. We’re also opening an experimental API to help you leverage these improvements. For details, see Batch custom field value retrieval API

You configure this feature with the jira.custom.field.indexing.batch.size property. Setting its value to 1 disables batching and any other number defines the number of issues that will be batched. 

To benefit from this change, a full reindex needs to be performed.

Known issue: Jira doesn’t recognize a MySQL database after the upgrade

If you're using a MySQL database, you might get the following error after the upgrade:

We can't tell what database you're using

That’s because your dbcongig.xml file is using mysql as the database-type. This type is no longer recognized by Jira after we ended support for MySQL 5.6, so you’ll need to update it.

To solve this issue:

  1. Stop Jira.
  2. Edit the dbconfig.xml file (in your home directory)
    • If you’re using MySQL 8.0, change the database-type to mysql8.
    • If you’re using MySQL 5.7, change the database-type to mysql57.
    • If you're using MySQL 5.6, you will need to upgrade your database first, as this version is no longer supported.

For more info about connecting Jira to MySQL, see:

Known issue: Azure SQL is reported as an unsupported database

If you’re running Jira with the Microsoft Azure SQL database, you will get warnings saying that you’re using an unsupported database. That’s because Azure SQL is mistakenly reported as SQL Server 2014, and we’ve ended support for this one in this release.

Solution: 

We’re working on the update of the Atlassian Troubleshooting and Support Tools app. For now, discard the warnings and wait for the available update. Your database is fine.

Increase your pool-max-size before upgrade

If you're upgrading from Jira 7.x to Jira 8.x we recommend changing the pool-max-size parameter to 40 in your dbconfig.xml before the upgrade. Leaving the default of 20 can sometimes lead to “ResultSet Closed” errors during re-indexing on 8.x. For information on implementing the change, see Tuning database connections.

An important bugfix requires full reindex

We fixed a bug that caused issues removed from sprint not showing in Burndown Chart or Sprint Report. The problem will automatically be fixed for all the newly created and edited issues and they will display in the Sprint Report and Burndown Chart.
If you are not concerned about the past issues, you don’t have to take any action. However, if you want to be sure all the past and current issues get fixed too, you need to perform a full reindex.

A bug in Tomcat causing issues on upgrade

Tomcat started to use double-quotes as of version 8.5.48 as a result of Expansion of JAVA_OPTS in catalina.sh containing '*' stops startup on linux bug. That's why when you upgrade to Jira 8.13 and set parameters in setenv.sh or setenv.bat, make sure that you:

  • Don't remove the double-quotes in the catalina.sh
  • Set all your parameters in one line without any new line in setenv.sh or setenv.bat

Otherwise you might experience issues starting up Jira. 

New events in the Advanced audit log DATA CENTER

We are adding new events to track priority (Created, deleted updated) and secure admin login (websudo) for you to have better insight into your application. 

  End of support announcements

In Jira 8.13, we are not making any changes.
