TL;DR

Upgraded XMTP SDK to version 4.6.2 with new features for group management, message sorting, and archive options.

What changed?

• Updated Android dependency from org.xmtp:android:4.6.1 to org.xmtp:android:4.6.2-rc1
• Updated iOS dependency from XMTP (4.6.1) to XMTP (4.6.2-rc3)
• Added support for group app data with new methods groupAppData() and updateGroupAppData()
• Enhanced message queries with new parameters: sortBy, insertedAfterNs, and insertedBeforeNs
• Improved syncAllConversations() to return a GroupSyncSummary object with numEligible and numSynced properties
• Made ffiRevokeAllOtherInstallationsSignatureText() return undefined when there are no installations to revoke
• Added excludeDisappearingMessages option to createArchive()
• Added support for referenceInboxId in reaction content
• Enhanced group creation to support app-specific data

How to test?

1. Test group app data:

   const group = await client.conversations.newGroup([address1, address2])
   await group.updateAppData(JSON.stringify({ customData: "value" }))
   const appData = await group.appData()

2. Test message sorting by insertion time:

   const messages = await conversation.messages({
     sortBy: "INSERTED_TIME",
     insertedAfterNs: timestamp
   })

3. Test sync summary:

   const { numEligible, numSynced } = await client.conversations.syncAllConversations()

4. Test archive with disappearing messages excluded:

   await client.createArchive(path, encryptionKey, undefined, undefined, undefined, true)

Why make this change?

This update provides developers with more control over group metadata through app-specific data, improves message querying capabilities with new sorting options, and enhances archive functionality. The changes to syncAllConversations() provide better visibility into the sync process, while the null-safety improvements in ffiRevokeAllOtherInstallationsSignatureText() prevent potential runtime errors. These enhancements support more sophisticated messaging applications with better data management capabilities.
