Jira Core 8.5.x upgrade notes
Here are some important notes on upgrading to Jira Core 8.5.
For details on the new features and improvements in this release, see the Jira Core 8.5.x release notes.
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 thechange, see Tuning database connections.
8.5.15: Changes in startup files
We've changed several startup files to change the format of GC logs produced by Jira while running with Java 11. Without the change, the logs are impossible to parse with the GCViewer tool and can be frustrating for an admin to work with.
We've changed the
tags,time,uptime,level in the following files:
bin/set-gc-params.shfile on Linux
bin/set-gc-params.batfile on Windows
bin/set-gc-params-service.batfile on Windows
If you don't have any custom changes in those files, you don't need to take any cation. If you do, you'll need to copy your changes to the new files on upgrade.
8.5.4: Support for PostgreSQL 10
We've added PostgreSQL 10 to the list of supported platforms. For more info, see Supported platforms.
8.5.4: G1 GC enabled by default for Java 11
If you’re running Jira with Java 11, Garbage First Garbage Collection (G1 GC) will be enabled by default. We’ve already been recommending this method when tuning garbage collection, so now you’ll get it out of the box. G1 GC is more efficient and improves performance, especially in environments with large Java heap.
|Java 11||G1 GC|
*Our performance tests have shown that you might benefit from ParallelGC if you have a relatively small Java heap. The difference is not big, but you can consider switching back to ParallelGC if you’re having problems with performance.
To change the default GC method:
setenv.sh/.batfile, and search for
JVM_GC_ARGS. You’ll find available parameters described inside.
If you’re running Jira as a service on Windows, you’ll also need to modify the
8.5.4: Changes in the issue collector
The upcoming update of the Chrome browser introduces new cookie security features, which would essentially break the issue collectors embedded on separate domains. We’ve fixed this problem, but this brought some changes to how issue collectors work:
You can no longer match the submitter’s user session to make them the issue reporter. You can still match them by using their email address.
You don’t have to enable 3rd party cookies to make the issue collector work. We’ve removed this requirement, also dropping some error messages that reminded about it.
The project and issue key will no longer be displayed in the success message after submitting feedback (unless the project is open to Anyone on the web). We did this to improve security by not disclosing information about projects and issues.
For more info on the issue collector, see Using the issue collector.
OAuth 2.0 support for incoming mail in Jira 8.5.9
With Google and Microsoft planning to disable Basic Authentication, we want to make sure you can still add your comments to Jira and create issues using email. We're adding OAuth 2.0 support so that you can use it as an authentication method for Gmail or Microsoft Exchange online instead of password.
Create your OAuth integration, then update your incoming mail server and leave the rest to us. We'll make sure the connection with your mail server works seamlessly. Learn more
Known vulnerability in the BKS-V1 keystore format
If you’re running Jira over SSL, we’d like to bring your attention to a security vulnerability of the BKS-V1 keystore format, provided by the BouncyCastle library. We strongly recommend that you don’t use it in your Jira instance. Learn more
