WAS v8.5 > OverviewDeprecated, stabilized, and removed features
If you are migrating from an earlier release of WebSphere Application Server, you should be aware of the various features that have been deprecated, stabilized, and removed since v6.x.
Deprecated feature: Refer to the tables in Deprecated features, Stabilized features, and Removed features to learn what has been deprecated, stabilized, and removed.
- Deprecated features
WAS uses the following naming scheme:
V.R.M.F where
- V = version
- R = release
- M = modification
- F = fix pack
For example, 8.5.0.1 refers to version 8, release 5, modification 0, and fix-pack 1. It is also common to use "version" to prefix a particular release, modification, or fix pack—"version 8.5" when referring to a release, for example, or "version 8.5.0.1" when referring to a fix pack.
If a feature is listed in Deprecated features as deprecated, IBM might remove this capability in a subsequent release of the product. Future investment will be focussed on the strategic function listed under Recommended Migration Actions in Deprecated features.
Typically, a feature is not deprecated unless an equivalent alternative is provided. A feature is not removed until at least two major releases or three full years, whichever time period is longer, from the release in which that feature is deprecated. Looking at a sequence of releases including 6.0, 6.1, and 7.0, for example, features deprecated in release 6.0 first become eligible for removal in 7.0. In rare cases, it might become necessary to remove features sooner; such cases are indicated clearly and explicitly in the descriptions of these features in Removed features.
For information on features that have been deprecated in this and earlier releases of WAS, read Deprecated features.
- Stabilized features
If a feature is listed as stabilized, IBM does not currently plan to deprecate or remove this capability in a subsequent release of the product; but future investment will be focused on thealternative function listed under Strategic Alternative in Stabilized features. We do not need to change any of your existing applications and scripts that use a stabilized function; but you should consider using the strategic alternative for new applications.
For information on features that have been stabilized in this release of WAS, read Stabilized features.
