From Xojo Documentation
As time marches on, some older features of Xojo may no longer be relevant, may be unsupported by the OS or may be replaced with a newer feature. In such cases, the Xojo feature will be marked as De-emphasized, Deprecated and then finally removed.
- De-emphasized means that the item's use is no longer encouraged and alternatives should be investigated. Bugs will not be fixed unless they cause fatal errors. At some point after an item is de-emphasized, it will be deprecated.
- Deprecated means that an item is no longer supported, although the item still works and remains available for use. If your projects require this item, you should consider finding another solution. Bugs are not typically fixed for deprecated items.
- Removed means the item is not longer available in Xojo. Typically deprecated items are removed about a year after they are deprecated, although this may be sooner or later as the situation warrants it.
This table describes the latest versions of Xojo you can use with some older operating systems.
