LXMF-rs v0.3.0

LXMF-rs v0.3.0 Release Notes

Date: 2026-06-12
Release commit: b86482412846c4f39f091c1d0c3e2718226881b4

This is a usable sub-1.0 LXMF-rs product and daemon bundle release. It promotes
the v0.3.0-rc1 line after additional propagation reliability, interop, and
operator-observability fixes landed on main.

This release is not a claim of complete drop-in Python Reticulum/LXMF
replacement parity. The maintained parity source of truth remains
docs/status/current-roadmap.md.

Scope

• Usable Rust implementation of core Reticulum and LXMF behavior with repeatable
  compatibility evidence against pinned Python Reticulum and LXMF references.
• GitHub binary bundle release for lxmd and reticulumd.
• Focused propagation-node, peer-sync, remote transfer, retained payload, and
  operator-status improvements over v0.2.0 and v0.3.0-rc1.
• Known partial parity for broader Python router lifecycle, external clients,
  and hardware/interface breadth.

Highlights Since v0.2.0

• Expanded propagation peer and router behavior, including restored queue
  replay, unpeer cleanup, duplicate receive accounting, peer cost restoration,
  admission gates, throttling, transfer limits, retained haves, and
  payload-backed peer queue snapshots.
• Broader remote propagation sync, fetch, download, unpeer, lifecycle,
  failure-kind, cancellation, close-signal, and source-peer backoff handling.
• Stronger Python compatibility coverage for peer sync, paper URI ingest,
  unknown handle behavior, remote status/control, Python-origin /offer, and
  propagation /get haves acknowledgement.
• Added and stabilized production interface work for AutoInterface, KISS, LoRa,
  RNode BLE, and VR-N76 KISS-over-BLE paths.
• Added rnstatus-rs daemon status coverage, including interface runtime state
  and propagation peer state.
• Added SDK and wrapper improvements, including contract/schema updates, Kotlin
  wrapper conformance, easier SDK examples, and ZeroMQ pipeline hardening.
• Added embedded mini-node and embedded interface support surfaces.
• Expanded CI, scheduled mesh/soak/HIL workflows, release readiness docs, and
  release bundle automation.

Changes Since v0.3.0-rc1

• Added live propagation interop cases for Python-origin /offer and /get
  haves acknowledgement.
• Preserved propagation lifecycle and queue state across no-access, ignored,
  malformed, failed, cancelled, and terminal remote transfer paths.
• Added source-peer backoff and recovery handling for failed or malformed remote
  fetch/download/import paths.
• Improved peer-sync visibility and retry behavior, including structured failure
  kinds, hidden-peer control lookup, failed local offer state, and payload-backed
  queue snapshot preservation.
• Improved retained propagation haves filtering, storage-pruning priority, and
  propagation ingest rejection semantics.
• Surfaced remote resource terminal events and remote link close signals for
  operator-visible diagnostics.
• Added BLE MTU readiness diagnostics.
• Added the Codex PR review workflow.

Current Version Train

GitHub release version: v0.3.0

Crate/package versions intentionally remain per the publish plan rather than one
blanket workspace version:

• lxmf: 0.3.0
• reticulum-rs-rpc: 0.3.0
• lxmf-sdk: 0.2.1
• lxmf-wire: 0.2.0
• reticulum-rs-core: 0.2.0
• reticulum-rs-transport: 0.2.0
• app/tool crates remain unpublished and are distributed through GitHub bundles

Validation Record

• Latest main CI before final release prep:
  https://github.com/FreeTAKTeam/LXMF-rs/actions/runs/27434941083
• Latest Python reference interop before final release prep:
  https://github.com/FreeTAKTeam/LXMF-rs/actions/runs/27431799116
• v0.3.0-rc1 published Linux, macOS, and Windows daemon bundles with matching
  .sha256 files.

Local RC gates for the release candidate branch included:

• cargo xtask ci: passed with LXMF_RS_BASH pointing to Git Bash.
• cargo xtask ci --stage sdk-soak-check: passed.
• cargo xtask ci --stage schema-client-check: passed.
• cargo xtask schema-client-generate --check: passed.
• cargo xtask publish-crates --wave all --dry-run --allow-dirty: passed
  through the release-tool fallback for unpublished local publish-wave
  dependencies.
• cargo run -p rns-tools --bin rnx -- e2e --timeout-secs 20: passed.
• cargo fmt --all -- --check: passed.

Known Limits

• Propagation interoperability and operational substitutability are still marked
  partial in docs/status/current-roadmap.md.
• Full Python surface parity is not achieved.
• External-client compatibility claims for Sideband, MeshChatX, and Columba
  require separate external-client interop gate evidence.
• Hardware and prepared-host evidence for all interface paths remains broader
  than the automated CI evidence.
