Changelog: v4.1.0...v4.2.0

Version 4.1.0

What's new in 4.1.0

• XEP-0363: HTTP Upload support for much faster and reliable media messaging. [1]
• XEP-0352: Client State Indication. Helps reduce network usage when running in the background.
• End-to-end encryption for file transfers in OMEMO or OTR sessions [2].
• Inline media previews for incoming URLs. (Optional)
• Bug fixes and refactoring.
• Tor 0.3.0.9

Caveats

• Your server administrator must enable support for XEP-0363. See mod_http_upload for Prosody [3] and ejabberd [4] for more details.
• Encrypted file transfer is required in OMEMO/OTR, but has limited compatibility for receiving clients. Users on the other end will receive aesgcm:// links [2].
• Inline media previews are enabled by default, but can be disabled on a per-account basis. This feature should be disabled if you have extreme privacy concerns or do not trust your contacts. This setting is always disabled for Tor accounts.

• NEW: Account migration tool. Automatically create new account, move existing contacts, archive old conversations, and optionally notify old contacts of new account info.
• NEW: Inbox / Archive. In addition to swipe-to-delete, there is now swipe-to-archive, which allows decluttering the inbox without deleting conversation history.
• Fix a nasty bug introduced in 4.0.7 that could prevent OMEMO sessions from working. If your outgoing OMEMO messages were no longer getting delivery receipts, send some messages back and forth and it should fix the issue. When you receive an undecipherable message it will clear the session, which allows the session to be re-initiated on your next outgoing message.
