Columba 2.0.0-beta

Installation

Pick a backend, then download the APK matching your device's CPU architecture.

• Python backend, RECOMMENDED — ships Mark Qvist's official python reference implementations of Reticulum and LXMF via Chaquopy.
• Kotlin backend — ships Torlando's EXPERIMENTAL, AI-GENERATED native reticulum-kt / lxmf-kt / lxst-kt stack.

The python version is highly recommended. The kotlin version is a work in progress, and is not yet verified to be completely safe.
The kotlin version may yield better battery life depending on your device, and comes in a smaller apk due to not requiring a python runtime.

Python backend (official-rns-py)

Kotlin backend (EXPERIMENTAL-reticulum-kt)

Telemetry variants:
Each APK above also has a -no-sentry variant without crash reporting for maximum privacy — append -no-sentry to any download link above (e.g. the most common builds: Python arm64-v8a no-sentry · Kotlin arm64-v8a no-sentry). Sentry collects stack traces when Columba encounters errors
and provides helpful information to the developer to improve Columba, but is hosted at sentry.io, and is thus not the maximum privacy option.

Not sure which to pick? Most Android phones use arm64-v8a. If unsure, use the universal APK.

Verification

See SECURITY.md for verification instructions.

Announcing Columba 2.0.0:

• BREAKING CHANGE: Changed Columba's wire format for replies and reactions to match MeshChatX. Replies and reactions exchanged with older versions of Columba will not be visible across the pre/post 2.0 boundary.
• Huge refactor of the backend architecture in Columba to allow for builds including either Mark Qvist's official reference implementation of Reticulum in Python, or Torlando's experimental, AI-generated reticulum-kt. Torlando's testing focus was exclusively on Python for this release.
• This refactor allows the UI to gracefully degrade when a feature (like interface hot swapping) is only available in one backend or the other. This also allows for the more recent UI improvements to come to the Python backend.
• The Kotlin version will install as a separate app on your phone, so you can run both side by side.
• Added the ability for Columba to share its reticulum instance (only tested on Python backend)
• Added LXST voice call privacy gates, to block those pesky spam callers. You can only allow from contacts, or disable entirely.
• Crash reporting is now opt in, even on the standard apks, and sentry is now fully removed from the -no-sentry variants at build time
