In order to change from versions 2.10.x to 11.x.y, Piwigo needs to only consider 11 as the branch, and not 11.x. Or else it will mess up with minor and major updates.
* ability to combine albums in URL index.php?/category/1/2/3 will consider 1 as $page['category'] and {2,3} as $page['combined_categories']
* new menu block "related albums" which displays only the hierarchy of albums related to the current set of photos, excluding current album(s). In the hierarchy, only the related albums have a link, not ancestors
* use configuration setting quick_search_include_sub_albums (default=false) to activate this feature.
* the list of sub-albums is not displayed in the list of album results (to avoid too long lists).

use standard structure for icons to remove a tag in a combined tags search
The icon displays with 2 tags combined instead of 3
To avoid breaking all themes, we keep the old style by default, but the new style is available. The upgrade to 2.11 documentation will mention it.
In PHP 7.2 and later you will get a warning if you call count() on null. So either initialize $errors to an empty array here, or use empty() to check it as I have done here.
This fix was initially only for branch 2.9, and branch master should have
received a new version of jshrink, but I forgot to do it before 2.10 and now
we have a regression in 2.10. This commit will be cherry-picked to 2.10 and
we also have it on master so that we don't have a new regression in 2.11 (in
case jshrink is not properly updated)
