2.1.0

0.1.1

What's changed

• Fix group contact lists to use the active group membership when the backup provides it.
• Deduplicate group participants by phone number so historical rows do not inflate the contact list.
• Improve @lid identity resolution through linked phone JIDs so more participants get the same display name shown by WhatsApp.

Result

Group participant exports now match the current member list much more closely and avoid duplicate historical entries.
