WTP 3.2.x Maintenance Plan

Overview

WTP 3.2.1 is a WTP-only maintenance release, planned for end of July. It will be built on exactly the same pre-reqs from the June Helios release.

WTP 3.2.1 will be available in our own webtools software repository, but not the Eclipse common Helios repository or EPP packages.

WTP 3.2.2 is for the first Helios simultaneous maintenance offering, delivered on the fourth Friday of September, 2010

WTP 3.2.3 is for the second Helios simultaneous maintenance offering, delivered on the fourth Friday of February, 2011.

For severe issues that require an immediate patch, see WTP Patches.

Scope

All WTP 3.2.x releases are service releases for critical defects, regressions, and adopter issues only. Specifically, there should be:

No UI changes (that would effect documentation, tutorials, etc.)

No NL changes (that would invalidate translations)

No API changes, or changes affecting known adopter usage.

No new function or features (especially those that would require an increment in minor version field).

Exceptions to the above are sometimes required, but they require WTP PMC approval.

In general, we will avoid changing the interface or behavior of any public method even if non-API.

All bundle versions must be updated (with an increment in the service level field) when the first change is made to for a service release. Similar for any feature (directly or indirectly) that includes the bundle. If a bundle (or feature) does not change, it's version should not change.

Bug Approval

All bugs must be approved by the project lead or their delegate using the bugzilla review flag. Project leads should send a note to wtp-releng to notify everyone of their choice or change in delegate(s).

After the first maintenance release candidate, all bugs must also be approved by the normal PMC Approval Process.
