View source for D32 General Platform Maintenance

= Overview =
The main goal of the platform corrective and evolutive maintenance is to fix the listed known bugs, and implement some new requested features. As in the previous years of Deploy, these bugs and features are reported either by mail or through dedicated SourceForge trackers.

The terse list below gives an overwiew of the noteworthy features added in the main platform during the past year:
* Proof replay of undischarged POs (releases 1.3 and upper)
: It often happens, while modifying a model, that a set of previously manually discharged POs are slightly changed and need to be discharged again. However, replaying the proof for those POs could most of the time be enough to discharge it. Hence, a command was added to manually try replaying the proofs for a set of undischarged POs. This request was expressed by [https://sourceforge.net/tracker/?func=detail&aid=2949606&group_id=108850&atid=651672 end users]. See [http://wiki.event-b.org/index.php/Proof_Obligation_Commands].
* Rule Details View (releases 2.0 and upper)
: When doing an interactive proof, one is guided by the proof tree appearing on the proof tree view. However, it is sometimes needed to get more informations about the rules being involved in a proof, such as instantiation details, hidden hypotheses, etc. The [http://wiki.event-b.org/index.php/Rodin_Proving_Perspective#Rule_Details_View Rule Details View] displaying such details has been added.
* Refactoring plug-in (releases 1.2 and upper)
:
* Documentation
: Plug-in developers expressed their need to get a detailed documentation about Rodin extension ability. A dedicated [http://wiki.event-b.org/index.php/Plug-in_Tutorial tutorial] has been written accordingly, and was the support of a training session given at the [http://www.event-b.org/rodin10.html Rodin User and Developer Workshop] in Düsseldorf this year.

See the [http://wiki.event-b.org/index.php/D23_General_Platform_Maintenance#Available_Documentation Release Notes] and the [http://wiki.event-b.org/index.php/D23_General_Platform_Maintenance#Available_Documentation SourceForge] databases (bugs and feature requests) for details about the previous and upcoming releases of the Rodin platform.

= Motivations =
The evolutive maintenance (resp. corrective maintenance) has its origin in the Deploy project's description of work, and the various requests (resp. bug reports) listed by WP1-4 partners, developers and users. Since the Deploy project's birth, various streams can be used to express feature requests or track an encountered bug :
: - [http://wiki.event-b.org/index.php/D23_General_Platform_Maintenance#Available_Documentation dedicated trackers],
: - mail to the deploy user list, etc.
During the WP9 meetings, maintenance tasks to perform are being given a priority and are assigned to an according WP9 partner (as mentionned in the D23). The higher priority is given to WP partners requests.
The following table describes the task that motivated the maintenance being done during the last Deploy project's year :
