I looked at the release notes for 2.5.1 and I guess it realy makes sense to "wait" on it to become available when on the verge of moving modules into production. Will there be a "huge" impact on deployment procedure ??

I am currently testing and using 2.5.1-rc1 and the deployment procedures are the same as for 18.104.22.168. The only difference I can see is that you might need to update some widgets to use new API, such as Excel Importer.
