There is now a new eRCP for Linux Qt release available from eRCP downloads. This release includes bug fixes for the eSWT port on Qt. Rest of the eRCP plugins have no changes. You can see a list of changes from release notes.
As always we would like your contributions, the easiest way to contribute is to download the release, test and report bugs. For those that would like to get their hands into the water, we are posting bugs with “helpwanted” keyword to bugzilla. If you would like to help with implementing the full SWT on Qt this bug may be interesting for you as it is the first step towards the SWT implementation.
