What's changed since the last LTS release
Jira 10.3 is a Long Term Support (LTS) release. It contains all features introduced since the last LTS version, Jira 9.12, and provides fixes for known issues in this version.
If you’re interested in learning more about a specific type of improvement, you can go to one of the following sections:
Async webhooks are now default in Jira Data Center
Starting from Jira Data Center 10.0.0, asynchronous webhooks are now the default and only option. This update significantly improves the user experience by processing webhooks through a dedicated thread pool, rather than tying them to the user request. Previously, in Jira 9 and earlier, webhooks were processed synchronously, with the most computationally intensive work performed during the HTTP request.
Environments with exceptional webhook usage in both Jira 9 and 10 might exceed the guardrails set by the default parameters. You can customize these limits to better suit your organization’s needs. We recommend testing the asynchronous webhooks within your staging environments before a final upgrade. If you experience any issues, check our list of known problems or reach out to our support team.

The summary of changes is divided by the versions in which they were released, but it doesn't mean you have to upgrade through each version separately. You can go straight from 9.4 or 9.12 to 10.3.
