Re: [eclipse-dev] Compatibility Release 4.x (x>1) to 4.1
The compatibility restrictions for 4.1
are very similar to the restrictions laid out for 3.x releases:
There are two significant differences
for 4.1 that come to mind:
1) All *new* API in 4.0 was marked as
provisional (marked as x-internal or x-friends in the bundle manifest).
Those APIs are subject to change in 4.1. Provisional APIs have been used
in the 3.x stream before, but on a smaller scale.
2) On Workspace Compatibility, we have
always had the disclaimer (in 3.x and 4.x), that "User
interface session state may be discarded when a workspace is upgraded".
However in practice in the 3.x stream we have been able to preserve almost
all UI session state across upgrades. In 4.1 this is certainly not the
case, due to some significant changes in the persisted format of that state.
Therefore when you upgrade from 4.0 to 4.1, things like perspective layouts,
dialog sizes, etc, will mostly be reset to their defaults.
Hope that helps,

|[eclipse-dev] Compatibility Release
4.x (x>1) to 4.1|
you state that “Eclipse 4.1 will
be compatible with Eclipse 4.0 (and all earlier 3.x versions).”
but also restrict that for
Is there the same compatibility of eclipse
4 like eclipse 3 (e.g. 3.6 to 3.5) after the “real” release of eclipse
4 with 4.1. Means that a change from 4.1 to 4.2 is like a change from 3.5
Or is there a change in the compatibility
policy by the eclipse developers?
What next?: keep on developing eclipse;
it rocks (i start to build rcps with eclipse version 2 ;))!
