| </div><p><a href="#toc">Table of Contents</a></p><h2><a name="release_milestones">Release Milestones</a></h2><div> |
| Release milestone occurring at roughly 6 week intervals and follow the |
| Platform milestone releases by approximately 1 week; that is, until the |
| final 3.7 release of the Platform, upon which CDO and other projects |
| will release simultaneously. CDO will deliver its milestones within one week of |
| the Eclipse Platform. It is anticipated that CDO will synchronize its |
| milestones with the Helios milestone schedule. |

| CDO will produce maintenance releases to align with the Helios SR |
| releases, that includes the Eclipse Platform 3.6.x release. |
| CDO may produce interim maintenance releases in addition to these in |
| order to satisfy client requests. Maintenance releases will only be published |
| if they have any new fixes to offer. |
| <ul> |
| <li>09/24/2010 - CDO 3.0.1 maintenance release (Helios Service Release 1)</li> |
| <li>02/25/2011 - CDO 3.0.2 maintenance release (Helios Service Release 2)</li> |
| <li>A list of issues indicated for the 3.0.x maintenance stream can be found in |
| bugzilla, or by using links on maintenance stream build pages.</li> |
| </ul> |
| </div><p><a href="#toc">Table of Contents</a></p><h2><a name="target_environments">Target Environments</a></h2><div> |
| In order to remain current, each Eclipse release targets reasonably |
| current versions of the underlying operating environments. The CDO Model Repository |
| Project (CDO) depends upon on the |
| Platform and other projects, which are mostly "pure" Java<sup>TM</sup>. CDO |
| will target the same Java version as EMF Core, which currently requires |
| Java 5. Eclipse Platform SDK 3.7 will be tested and validated on a |
| number of reference platforms. CDO will be tested and validated |
| against a subset of those listed for the platform. |
| </div><h3>Internationalization</h3> |
| <div> |
| The CDO Model Repository is a runtime technology with most of the |
| components having no user interface. The remaining user interface |
| parts of CDO are considered exemplary and thus no attention has been |
| paid to externalize them for internationalization. |
| </div> |
| <p><a href="#toc">Table of Contents</a></p><h2><a name="compatibility">Compatibility with Previous Releases</a></h2><div> |
| The 4.0 release of the CDO Model Repository will contain a large set of new |
| functionality and an enhanced API as driven by the community. Therefore CDO |
| will not be binary compatible with previous releases. Careful attention |
| has been paid to minimize the API related changes and the resulting impact |
| to existing applications based upon CDO. |
| </div><p><a href="#toc">Table of Contents</a></p><h2><a name="themes_and_priorities">Themes and Priorities</a></h2><div> |
| A list of project requirements and agreed upon |
| implementation time frames is found in this document. For the |
| milestones listed in this document, a set of overall themes is used |
| to indicate what major set of functionalities is to be concentrated |
| on for each. These themes are presented below, while the requirements |
| document and associated Bugzilla entries are left to those wanting |
| more detailed information on each. |
| </div><h3>Power to the People</h3><div> |
| Major improvements in the API and configuration will give clients considerably more |
| control over the behaviour and performance of their repositories and sessions. |

| The CDO project has a proven track record of quality, reliability, and extensibility |
| but all these aspects can be continuously improved. |
| Existing and new clients often desire more functionality from the framework |
| while long established clients generally desire mostly improvements in performance. |
| Often these two are at odds since additional extensibility often has a performance cost |
| and any changes, even performance boosting ones, potentially impact reliability. |
| Every effort will be made to introduce new capabilities |
| so that they have negligible impact on established clients |
| based on the guiding principle: |
| if you don't use it, |
| you don't pay for it. |
| Because service and support has and always will take priority over new development work, |
| development commitments and schedules are subject to arbitrary change, slippage, or even deferral. |
| Be sure to establish direct communication to ensure that any hard commitments |
| are seen as that by the development team itself! |
