Why it matters for builders
To install or upgrade, choose Elastic Stack 9.4.5 instead of staying on 9.4.4. Treat 9.4.5 as the version to install. Before you start, refer to the release notes so you know the issues that have been fixed and the full list of changes for each product in this version.
Market and competitive context
A common gotcha is remaining on 9.4.4 when 9.4.5 is the recommended release. After you upgrade, confirm you are on 9.4.5 and check the release notes again to verify the issues that have been fixed and the full list of changes for each product in this version.
