Jira Core 9.4.x release notes
We're pleased to present Jira Software 9.4 Long Term Support version.
Highlights
Upgrading from 8.x to 9.x triggers full Jira reindex that causes some downtime during the process. If you’re on 8.x now, make sure you’ve estimated the downtime and set the best time for the upgrade.

Whether you’re upgrading from Jira 8.x or Jira 9.x, see our Long Term Support release upgrade guide for all the necessary steps.
Over the past few months, you've shared a lot of feedback on the changes we made to comment sorting in Jira 9.0. Taking into account this feedback, we’ve improved commenting experience in the latest 9.4.6 release.
We’re bringing back comment sorting behavior from Jira 8.x and introducing a sticky comment footer, which is currently available behind the feature flag.

What's changed since the last LTS release
Jira 9.4 is a Long Term Support (LTS) release. It contains all features introduced since the last LTS version, Jira 8.20, and provides fixes for known issues in this version.

Performance reports
We run extensive performance tests to compare our Long Term Support releases to see how the new features affect Jira and to make sure we’re not introducing any performance regressions. LTS releases are usually a few versions apart, so the improvements in performance are much more visible than between smaller, feature releases.
