Features

• Feature: [sharing] add sharing-by-group/realm
• Feature: [group] with type "htgroup", "none", "from_auth" (NEW)

Fixes

• Fix: storage/multifilesystem: depth:1 PROPFIND no longer re-runs the filesystem collision check (path_to_filesystem) for every item in a collection; this made listing large collections O(n^2) on file systems not detected as collision-free
• Fix: pathutils: detect missing permission to create symbolic link on Microsoft Windows
• Fix: sharing-by-token: requests to dedicated items

Improvements

• Improve: storage/multifilesystem: avoid redundant stat() calls per item in get/upload when use_mtime_and_size_for_item_cache is enabled

Extensions

• Extension: [auth] type "pam": set groups of user to be used later
• Extension: [hook] add option for "smtp_password_file"
• Add: [group] group_collections_folder replacing hardcoded "GROUPS"

Adjustments

• Adjustment: reject usernames starting or ending with "@" or having more than one "@"
• Adjustment: reject usernames containing ":" or ","
