Hi,
first of all I need to emphasize that this isn't a good approach as described in few of our articles, you shouldn't change the MonoX original files in order to have a simple upgrade process, and if you do so then you should definitely use source control system to track that changes before you do commits (I think that I have explained that to you in one of the posts here).
Basically you need to sync, as I mentioned earlier, Blog WebParts which includes the following:
08.11.2012. 17:23 971 BlogCategories.ascx
23.11.2012. 14:24 3.990 BlogComments.ascx
05.12.2012. 08:23 1.692 BlogCommentsList.ascx
08.11.2012. 17:23 1.103 BlogContainer.ascx
15.10.2012. 09:41 668 BlogInfo.ascx
30.11.2012. 23:10 883 BlogList.ascx
03.12.2012. 13:27 1.343 BlogManageCategories.ascx
06.12.2012. 12:22 6.544 BlogPostEdit.ascx
30.11.2012. 23:10 2.480 BlogPostList.ascx
08.11.2012. 17:23 1.180 BlogPostView.ascx
05.12.2012. 08:23 2.408 BlogSettings.ascx
30.11.2012. 23:10 347 TagCloud.ascx
FYI we will try to expose the changed source file list in change log in one of the following nightly builds.
