V1.4.1 (11/6/2010)

Bug fixed

Fixed launcher of Compiler V2 (which remains experimental).

V1.4.0 (31/1/2010)

New features

It is now possible to add an @deprecated tag to prevent from using some features. (feature request #5272).
Collections now implement an each operation that provides contextual informations like "first element", "last element", "element count" during the iteration . (feature request #9331).
Added an "Extended error view" which allows to see the details of a given error even if it contains many informations on many lines. (feature request #8099). It works by selecting an error in the standard error view or by hovering your mouse over an error.

Improved features

Support for property file in compiler V1. (feature request #9106).

Bug fixed

Fixed a big memory leak, that force the user to use the "Kermeta trash bin". This button should not be needed anymore.
#3724; How to suppress the kermeta nature of a project ?. Now we have clear actions to add Kermeta nature and remove kermeta nature on projects.
#4339; when calling kmlogo interpreter cannot call the compiler anymore and vice versa
#5278; conflict and crash if there is an alias to an Enumeration
#5735; KPM performance problems on check-out of very large projects.
#6092; Only a 'null' word when saving model if MM not registered
#6466; Console is closed before interpreter can report an error.
#7759; km2Ecore doesn't save the documentation of the invariants.
#8858; failed to run the full logo tutorial on some OS due to bluetooh module. The Logo sample has been refactored and a tutorial has been created for it in the eclipse help.
#9465; KMT printing fails on Linux and Mac OS X after OCL conversion.

V1.3.2 (27/10/2009)

New features

It is now possible to add an opposite to a reference or attribute by aspect and support model loading conformant to this specification (feature request #7637).
It is now possible to load a resource that comes from EMF EPackage registry in order to create ecore models that depends on the nsURI instead of a file. (feature request #7944).
New action UMLprofile2ecore. It is now possible to transform a uml profile into an ecore for use with kermeta via a right click on the uml file (feature request #7946).
Added a checkInvariant thats check only one invariant. You can now control the way the invariants will be checked. (feature request #4342) (The implementation is still partial since the current checkAllInvariants still uses the old way and not this new operation.)
Require can now use "platform:/lookup/" in addition to "platform:/plugin" and "platform:/resource". The current implementation of the lookup searches in resource (ie. workspace) first, then, if not found, searches in plugin. (feature request #6568 and feature request #8783) This greatly eases the development of kermeta code that is intended to be deployed in a plugin later.

Improved features

Several compiler improvements : "Filter the main operations to limit the runners generation" (feature request #7578), "Add an action to create the *.compiler.properties file" (feature request #7584) and "Enable to add operation to the EClass EObject by aspect" (feature request #7740).
EPackage registration improvements : now the EPackage registry view display all the declared nsURI, even those that haven't been loaded yet. It also displays the plugin name for those that comes from a plugin (feature request #7884) added a new action on Ecore : EPackage "re-"registration (feature request #7672).
FileIO improvement : Save text file with a specific encoding (feature request #7699).
Date improvement : Added an operation on Date for getting the current date (feature request #7742).

Bug fixed

V1.3.0 (09/03/2009)

New features

A compiler for you kermeta code. Still experimental in this version, it generates the all the java code to be run with EMF. You can deploy the resulting code in your product without installing kermeta in your product. Preliminary tests have shown x35 to x50 speed up compared to the interpreted mode. However, some feature of kermeta are still not supported by the compiler (see the current limitations : http://www.kermeta.org/community/dev/compilerCompilingIssues )
Kompose is now part of Kermeta update site : it allows to define a specialization to compose your model. Currently, it is bundled with the following sample specialization : Ecore and rdbschema.
Singleton pattern with Kermeta (feature request #7228). Thanks to Kermeta aspects, you can now use a pseudo singleton in your kermeta code. Be sure to use it only when there is no better design.
Date manipulation. (Feature request #7240)
Possibility to register an ecore file directly from Kermeta. ( feature request #6810). It uses a safe way to register, if the nsUri is already registered form a plugin it will do nothing.

Improved features

Ket now supports kermeta aspect. You can customize the name of the "generate" operation and weave it into an existing class. (see Feature request #6976)
Better support for invariants : An attribute has been added to the exception InvariantViolated that point to the invariant itself. This allows analysis of the invariant for feedback to the end-user. (this part of Feature request #1120)
New MDK dedicated to manipulating kermeta models. All special helpers and functions are now gathered in this MDK rather that put into the framework.
Improved navigability from the outline (Feature request #5685)
kpm preferences now allow to exclude projects and folder (feature request #6647)

Bug fixed

#5114; Editor crashes with ANTLR 3.0.0. We now clearly separate antlr2 from antlr3.
#6133; Ecore generics not usable in Kermeta
#6571; java.lang.NullPointerException on the .new function
#6582; (in)compatibility with Topcased 2.2 The editors now works with Topcased 2.3 and 2.4
#6634; readonly on attribute and reference not used
#6986; Kermeta internal error due to not implemented derived property
#7109; non explicit message when loading a model without the associated "require"
#7171; Merger : generic types are not binding in the km file
#7306; The tags on properties are lost in the merger

V1.2.0 (01/10/2008)

New features

Better support for invariants : CheckInvariant now also checks the multiplicities. An attribute has been added to the exception InvariantViolated that point to the faulty object. This allows a recovery and /or analysis of the invariant.
Added a preference page to let the user select which logger he wants to use and select the configuration file for log4j
Added a preference page to let the user configure some options of KPM. Also added a recovery button to reset KPM to its default configuration.
Improved feedback on some errors and exceptions. (For example, ResourceSaveException has now a new attribute pointing to the faulty instance)
Improved stop button (now you can stop kermeta, you'll get a stacktrace of the last instruction run)
A view dedicated to see kermeta documentation of your code in the same spirit as javadoc. (see Feature request #2066)

Improved features

Kermeta perspective displays some additional useful wizards for Metamodel engineering.
Improved KermetaDoc view.

V1.1.0 (03/03/2008)

New features

Improvement of the speed of the typechecker (x2).
Addition of "Clean" and "Typecheck this file" button in the toolbar in order to help with some trouble of the typechecker.
Improvement of UML MDK for profiles support.
#4365; internal error should be reported into the error log
#139; Implement "orElse" and "andThen". Partial support : the operations are available on boolean, but no dedicated surface syntax has been deployed yet.
#1022; degraded editor response time when used for long time.
#1759; Improving loading performances. (applies to the loading of kmt files)
Please note that kermeta metamodel now use a nsURI that includes a version umber in order to improve version robustness. In this release the nsURI is "http://www.kermeta.org/kermeta/1_0_0//kermeta"

Bug fixed

V1.0.0 (29/01/2008)

New features

Removal of the "kermeta::reflexion" package. This greatly simplifies the reflexivity without loss thanks to the use of aspect on Kermeta framework itself. If some of your code were using it, you simply have to replace all "kermeta::reflexion" by ""kermeta::language::structure".
Added dedicated keyword "aspect" in order to replace the old @aspect "true" syntax. The old syntax is still supported for backward compatibility.
Deployment of the first version of a UML MDK for basic support of UML and its profiles. (contributions are welcome)

Bug fixed

Fixed various bugs in the outline and in the reactivity of the textual editor.

V0.4.1 (04/05/2007)

New features

Metamodel weaving : thanks to the special annotation @aspect it is now possible to separate concerns in several files. It allows to add feature to an existing class. For example you can directly require the original ecore and use aspects to add the behavior or constraints to it. If your behavior needs some additional feature in your class, no problem, add it in the aspect. (#120; Kermeta PackageMerge)
#277; An OCL like syntax for casting. You can now use something like : myObj.asType(String)
#971;Getting (numerical) value from a string
#1493;Need for new operations on Kermeta collections.A number of new operations are now available: Collection.count(); OrderedCollection.indexOf(); Set.intersection(Collection) : Set; Set.union(Set) : Set; Set.unionWithBag(Bag) : Set; Set.minus(Set) : Set; Bag.union(Collection) : Bag; Bag.intersection(Bag) : Bag; Bag.intersection(Set) : Set

V0.4.0 (28/01/2007)

New features

Kermeta project nature is now useful: It supports a workbench rule engine for running automated task. So, whenever a file change it can activate some rules. Typically, it will be used to produce a km or an ecore corresponding to a kmt file. The rules can be customized through the kpm model (Kermeta Project Manager) You can even provide your own rules using Eclipse extension points. (In future release you'll be able to run kermeta transformations)
#1411; add a test that check that java5 is used
#1291;Improvement of syntax of pre/post conditions

Bug fixed

Textual syntax for pre and post has been enhanced. The previous version wasn't user friendly. If you want more details about the pre/post new syntax please look this page : http://www.kermeta.org/download/migration_changes/syntax_v032_v040. In order to migrate your files that use the old syntax, we provide a migration tool. (You need to use it only if you have pre and post condition in your kmt files)

Bug fixed

V0.2.2 (22/06/2006)

New features

#146; Contract support in Kermeta Jean-Marie and Cyril have developped the first version of contracts for Kermeta. It currently uses only Kermeta surface syntax. It fully supports pre/post when calling operations, and provides checkInvariant methods on Object. However, the metamodel is ready to support OCL syntax in the future. The control on pre/post verification is very basic (on/off) and may be improved later
#520; Multiple Consoles for different Kermeta App Instances

Bug fixed

#222; console frozen after "generate ecore". Now there is one console per running program.
#245; aliases not correctly exported to ecore

We have also improved the distribution packages. Now, if you want to install Kermeta, the update site provides Kermeta and all its dependent plugins (we have mirrored them). The installation is much simplier: Download Java5 and Eclipse, install Java, unzip eclipse, set up the update site and install everything from there... The graphical editor has also been separated so you may use kermeta even without all the plugins related to this (Topcased and all its dependecies).

V0.2.1 (19/04/2006)

Bug fixed

V0.2.0 (07/04/2006)

New features

#147; Dedicated Graphical editor for Kermeta This is the first version of a graphical editor for Kermeta (generated with TopcaseD) feel free to report any missing feature and bugs ...
#255; Metamodel of kermeta km file is not the same as internal kermeta view We have done a big refactoring to the internal EMF structure so it will store kermeta models (ie. *.km files) with exactly the same representation as the one viewed from the reflexivity within Kermeta. Please note that older km file are no longer compatible, you have to regenerate them

Bug fixed
