v1.4.4

Full Changelog: v1.4.3...v1.4.4

Mesh 1.4.3

File transfers no longer crash the app, including on low-RAM phones.

Fixes

• Stream files from disk instead of loading the whole file into memory
• Cap the Bluetooth write queue so a transfer cannot OOM the process
• Send files off the main thread so the app stays responsive
• Reassemble incoming files on disk and keep a smaller BLE packet buffer

Existing 1.3.6+ installs can update in place from this APK (app-release.apk).

v1.4.2

Full Changelog: v1.4.1...v1.4.2

v1.4.1

MESH v1.4.1 — delivery, identity, and a real release APK

This build is app-release.apk (versionCode 27), not a debug APK. Installs from v1.3.6–v1.4.0 can update in place. Studio debug builds still need an uninstall first.

What users should notice

• Messages typed with nobody nearby stay waiting for a nearby phone instead of flipping to failed.
• A checkmark means the other phone acknowledged the message, not that a neighbor merely forwarded it.
• If a known contact advertises a different signing key, the chat shows a fingerprint warning and ignores the new key.
• Nearby empty states distinguish Bluetooth off, missing permission, and still searching.
• The Mesh notification has Stop nearby chat.

Under the hood

• Pending messages are kept until an authenticated ACK or 24 hours, not deleted after the first hop.
• Direct ACKs can use the incoming Bluetooth link (two-phone chat).
• Packets are authenticated before they occupy the duplicate cache.
• New installs keep the signing key in Android Keystore; existing installs keep their current identity files.
• The upload keystore is no longer tracked in git. Git history still contains it — treat that certificate as compromised, and put signing secrets in GitHub Actions if you want CI to build future releases.

Chat payloads are still signed plaintext, not end-to-end encrypted. Relays and radios in range can read message bodies.

Checks

• ./gradlew testDebugUnitTest assembleDebug passed on the developer machine.
• This APK is a non-debuggable release build, signed with the existing Mesh upload certificate.
• Two- and three-phone radio tests were not run for this tag. See docs/HARDWARE_TEST.md.
