= Overview =
 
The purpose of the platform corrective and evolutive maintenance is to address bugs and feature requests.
 
  
The outstanding new features in the main platform for the past year are listed below:
 
* Mathematical Language V2 (releases 1.0 and upper)
 
: The new version of the mathematical language is supported.
 
: See [http://wiki.event-b.org/index.php/Event-B_Mathematical_Language http://wiki.event-b.org/index.php/Event-B_Mathematical_Language].
 
* Theorems everywhere (releases 1.0 and upper)
 
: It is possible to mix theorems and regular predicates in axioms, invariants and guards.
 
* Auto-completion (releases 1.0 and upper)
 
: When entering a predicate or expression in the Event-B machine / context editor, it is possible to type <tt>C-Space</tt> to see a list of possible identifiers that could be entered at the cursor position.
 
* Entering mathematical symbols (releases 1.1 and upper)
 
: The Rodin platform provides many more ways to enter mathematical symbols:
 
: - either type the ASCII shortcut (as in previous releases),
 
: - or type the LaTeX command (as defined in style <tt>bsymb</tt>),
 
: - or click in the ''Symbol Table'' view which displays the symbols graphically,
 
: - or directly enter the Unicode value of the symbol (for advanced users).
 
: See [http://wiki.event-b.org/index.php/Rodin_Keyboard http://wiki.event-b.org/index.php/Rodin_Keyboard].
 
* Camille Text Editor (releases 1.0 and upper)
 
: See [http://wiki.event-b.org/index.php/Text_Editor http://wiki.event-b.org/index.php/Text_Editor].
 
 
See the [[#Available%20Documentation | Release Notes]] and the [[#Available%20Documentation | SourceForge]] databases (bugs and feature requests) for details about the previous and upcoming releases of the Rodin platform.
 
 
= Motivations =
 
The main evolutions of the Rodin platform are driven by the description of work for the DEPLOY project and the requirements expressed by industrial WP1 to WP5 partners or by consultants during the lifecycle of the project.
 
 
Beyond that, any user registered on SourceForge may record any encountered bug on the Rodin platform or request a new feature, using the dedicated [[#Available documentation | trackers]]. Depending on the category, the bug / feature is assigned to the WP9 partner who is in charge of its treatment:

The priorities are discussed during the WP9 meetings.
 
 
= Choices / Decisions =
 
The WP9 partners have agreed on a release policy (see the [[#Available%20Documentation | Rodin Platform Releases]] wiki page). In particular, a new version of the Rodin platform is released every 3 months, a wiki page is dedicated to each release, and the code is frozen during the 2 weeks preceding each release.
 
 
The main advantages, for both developers and end-users, are summarized below:
 
* Information. The wiki page dedicated to each release provides instant information on the new features and improvements, which may be discussed if necessary.
 
* Validation. The period of code freeze is more especially devoted to bug fixes, and the frequency of the stable releases is ensured.
 
* Integration. A synchronization between the optional plug-ins and other plug-ins is now possible.
 
 
= Available Documentation =
 
The following pages give useful information about the Rodin platform releases:
 
* Release notes.
 
: See [http://wiki.event-b.org/index.php/Rodin_Platform_Releases http://wiki.event-b.org/index.php/Rodin_Platform_Releases].
 
: More details are provided in the notes distributed with each release (eg. [http://sourceforge.net/project/shownotes.php?release_id=693928 http://sourceforge.net/project/shownotes.php?release_id=693928]).
 
* Bugs.
 
: See [http://sourceforge.net/tracker/?atid=651669&group_id=108850 http://sourceforge.net/tracker/?group_id=108850&atid=651669].
 
* Feature requests.
 
: See [http://sourceforge.net/tracker/?group_id=108850&atid=651672 http://sourceforge.net/tracker/?group_id=108850&atid=651672].
 
 
= Planning =
 
The [[#Available%20Documentation | Rodin Platform Releases]] wiki page lists in particular the upcoming releases and give the scheduled release dates.
 
 
Special efforts will be made on the following topics:
 
* Team-based development.
 
: The purpose is to perform simultaneous developments.
 
: In order to understand the problem properly, some usage scenarios (see [http://wiki.event-b.org/index.php/Scenarios_for_Team-based_Development http://wiki.event-b.org/index.php/Scenarios_for_Team-based_Development]) for team-based Development have already been written, and a page has also been started to express merging proofs scenarios (see [http://wiki.event-b.org/index.php/Scenarios_for_Merging_Proofs http://wiki.event-b.org/index.php/Scenarios_for_Merging_Proofs]).
 
: A prototype plug-in is available, which enables the use of the EMF compare editor for machines and contexts. The DEPLOY partners will try out this plug-in and gather requirements for the teamwork plug-in.
 
: See [http://wiki.event-b.org/index.php/EMF_Compare_Editor_Investigation http://wiki.event-b.org/index.php/EMF_Compare_Editor_Investigation] (Implementation issues).
 
: See [http://wiki.event-b.org/index.php/EMF_Compare_Editor_installation http://wiki.event-b.org/index.php/EMF_Compare_Editor_installation] (How to install the EMF Compare editor).
 
: See [http://wiki.event-b.org/index.php/Teamwork_Requirements http://wiki.event-b.org/index.php/Teamwork_Requirements] (Feedback page / Requirements).
 
 
* Documentation.
 
: The purpose is to continuously increase the available documentation on the Wiki. It may contains requirements, pre-studies (states of the art, proposals, discussions), technical details (specifications), teaching materials (tutorials), user's guides, etc. The intended audience may be the developers or the end-users.
