5 +Before the introduction of the Nested Pages concept (in 7.2), the content in a wiki was organized like this:
6 +* we had some **Spaces**, that you can see as "folder"
7 +* inside these spaces, we had **Pages**, where you were able to write some texts or store applications entries.
8 +
9 +In that time, we cannot have spaces inside spaces, so all pages were placed inside a one-level space. The pages were identified like this: ##NameOfTheSpace.NameOfThePage##.
10 +
11 +Some pages were a bit special. They were the "home" page of a space. Every time a user wanted to reach a space without specifying a precise page name, she were redirected to that space home page. These pages were called "WebHome" (because at the very beginning of XWiki, "spaces" were called "web").

1 1  Ideas:
2 2  * Replace SpaceDocs and Spaces Panels with Navigation, Siblings and Children Panels.
3 +* Some existing code may break slightly and needs to be adapted: code taking some user input and creating Spaces based on that will most likely display {{{"\."}}}, {{{"\:"}}} and {{{"\\"}}} in the UI. Unless the code already cleans the user input and removes ".", ":" and "\" characters. So for example if a user enter a Space name of "my.space":
4 +** before 7.2: the code would create/display a Space named "my.space"
5 +** after 7.2: the code will create/display a Space named "my\.space"
6 +* Various XWiki API that used to return a space name have been returning a space reference string (i.e. list of spaces separated by dots and escaped {{{"\."}}}, {{{"\:"}}} and {{{"\\"}}} characters). Code using those API may need to be updated. See [[XWiki 7.2 release notes>>xwiki:ReleaseNotes.ReleaseNotesXWiki72||anchor="HSpaceReferenceinsteadofSpacename"]] for more details (this content could be copied in a section of the migration guide).
