1.3 Release Highlights
New and noteworthy
Slight improvement of the matching phase cost, improving the overall time of comparison. A number of memory leaks were tracked and hunted down for this release.
Major imrpovement of the ordering handling throughout EMF Compare : merging differences on ordering, merging addition and removals that change the ordering, detecting and merging ordering differences on attribute values...
Huge improvements on the merging process of EMF Compare, adding thousands of unit tests and fixing the failing corner cases.
Filtering and Grouping
Adding the possibility to filter and group diffs together in the comparison UI, along with the corresponding extension points.
Adding graphical comparison (match, diff and merge) capabilities as well as comparison editors for integration with GMF and EcoreTools.
Adding a specific comparison engine for SYSML models.
Quality of APIs
The component lead certifies that the requirements for Eclipse Quality APIs have been met for this release. All non-API code is in "internal" packages.
End of Life Issues
EMF Compare 2.0 is in the work and is what will be released with Kepler next year. There might be more releases in the 1.x stream, but they will only be meant for maintenance. Version 2.0 is a major overhaul of EMF Compare which aims at fixing the architectural and technical limitations induced by the 1.x implementation.
As such, all APIs provided by 1.3 are to be considered obsolete and none will be maintained in its current state with 2.0, be it core or peripheral.
