How it's work for my different users who are not in v1.1 but perhaps in 1.2 or 1.3 ? The update is not the same and for me the updater does apply patch recursivly from current version to last version alone.
As it is now, wyBuild creates "direct patches" from the old version to the new version. So if your latest version is 1.4, and your user is using 1.1 then they will get the direct patch from 1.1 to 1.4. Simarly if your user is using 1.2 they'll get the direct patch from 1.2 to 1.4.
In wyBuild 2.7 we're adding "incremental patch" support. That is, you'll have the option of forcing the users to download and install all the incremental steps to get to the latest version. So if the user has 1.1 then you can force wyUpdate to download and install 1.2, 1.3, and finally 1.4.
Does this answer your question.
