Release compatibility
Every Delphi release is delivered as a single version. When you set that version for your deployment, all of the platform's services are designed and tested to run together — you never mix versions between services. Upgrading is simply moving your deployment from one release to the next.
This page is about how the platform's own services fit together across releases: which releases are available, which one to run, and which services changed in each. If you build voice apps on the client SDK, see SDK compatibility for how SDK versions line up with platform versions.

Which release should I run?
- Run the release marked Current. It is the newest tested release and gets the latest fixes.
- If your release line has a latest patch, apply it — patches contain fixes only and are always safe to take.
- Supported releases still receive critical fixes, but plan to move to the current release.
- Superseded releases are no longer updated; upgrade when convenient.
What changed in each release
A release upgrades every service together, but not every service changes in every release — many are carried forward unchanged. The table below shows which services got a new build in each recent release. To pick up a particular service's update, run at least the release where it last changed.

Updated means the service got a new build in that release. To pick up a service's update, run at least the release where it last changed (the Last updated in column). Services with no recent change are carried forward unchanged and need no action.
