Pigeon 2.0 is an entirely new version of the MP02's encryption feature compatible with Signal. Pigeon 2.0 has been developed on recent Signal source code, with maintainability as a core objective. The Signal baseline for this first release has been rebased to Signal version 6.25.5 to encompass recent changes in the app and offers new features such as backup chats.

The Development of Pigeon 2.0

The original Signal source code has been left unchanged with Pigeon 2.0 to facilitate maintenance and keep it in regular sync with Signal. Future Pigeon updates will be released more frequently from version 2.0 onwards to ensure compatibility with the latest Signal app versions. New features will also be added in future rollouts.

With Pigeon 2.0, we invite the community to participate in contributing to the future development of Pigeon on the official Punkt. subreddit here, and on Github here.

A new version of Pigeon (v.2.0.0026) has been released to ensure ongoing compatibility with the Signal service. This update is required to avoid issues related to service continuity and to resolve some important bugs.
⚠️ Important:
Do not uninstall Pigeon from the Application Manager before installing the new version.
Please use the Update function to keep all your data intact.

Changes

1. Version number: Version number has been updated to v.2.0.0026
2. Re-base: Pigeon has been rebased to Signal 7.41.3, improving security, performance, and compatibility with Signal’s current infrastructure.
3. Backup restoration: Fixed an issue where the restore option was not automatically triggered during account setup, even if a valid backup was available. Previously, users could trigger the restore only by quitting and reopening the app mid-setup, which also introduced further issues. The restore flow now works as expected.
4. Verify backup passphrase input: Resolved a regression where the input field for verifying the backup passphrase did not show the typed characters, making it hard for users to confirm their input.
5. No visual feedback in Backup menu: Rewrote the UI in Settings → Chats → Chat Backup. Selected items in the list are now correctly highlighted when browsing.

Known issues

1. Settings menu: Although the correction has been implemented, we are aware of some interface problems in the Settings menu. These will be resolved in a next update, which will be released shortly.
2. Link devices: The functionality of linking devices is currently not available. We are working to rewrite it and include it in the next release.
3. Restore procedure UI feedback: No visual feedback during the restoration process. When the user enters the PIN, the restore begins and may take some time, depending on the amount of conversation history. Wait for the completion of the procedure without repeating the operation.
4. Group Call Info: The list of participants in a group call is not scrollable.
5. End of the call doesn’t work when the user exits Pigeon: When the user exits the Pigeon app during a call, the end call button of the keyboard is no longer intercepted and the call cannot be ended. To end the call, it is necessary to re-enter the call menu and click on the End Call option.
6. Set-up: It is not possible to select image tiles with the Punkt. key during the CAPTCHA test. It is necessary to use the numerical key '5' instead.
7. Voice messages: The duration of a voice message isn't displayed when dictating the message.
8. Voice messages: It is not possible to adjust the volume while listening to a voice message.
9. Conversations: Tagging functions are not enabled on Pigeon while typing messages.
10. Conversations: It is not possible to view media in full-screen mode; therefore, video playback does not work, and received images are only displayed as thumbnails.
11. Conversations: It is not possible to start a conversation with a voice message. Text messages must be exchanged first.
12. Calling: The call will drop if a call is answered on speakerphone.
