# iRedMail release notes and upgrade tutorials !!! attention * iRedMail source code: . * Download the [latest iRedMail stable release](https://www.iredmail.org/download.html). [TOC] ### Why keep your iRedMail server up to date * The latest iRedMail release brings new features, improvements, and bug fixes. * If you plan to migrate to a new iRedMail server someday, migrating iRedMail to another server which runs the same release is the easiest path. ### How upgrading works * Usually, upgrading iRedMail is just updating some config files to achieve new features or fix bugs, you do __NOT__ need to download and run the latest iRedMail installer (`bash iRedMail.sh`). * __Do NOT skip releases__. Upgrades are only supported from one release to the release immediately following it. * If you're looking for upgrading a very old iRedMail server to the latest iRedMail release, there's an alternative solution: [Migrating to a new iRedMail server](./migrate.to.new.iredmail.server.html). ### Release notes and upgrade tutorials !!! note "Paid Remote Upgrade Support" We offer remote upgrade support if you don't want to get your hands dirty, check [the details](https://www.iredmail.org/support.html) and [contact us](https://www.iredmail.org/contact.html).
