Stirling PDF's 3.x line ships bulk processing, org-wide signing and fortnightly feature releases
A side-by-side editorial comparison of Apollo Config and Betaflight — release velocity, themes, recent moves, and the top alternatives to consider.
Apollo 3.0 moves to Java 17 and pitches configuration management at AI agents.
Apollo ships a feature release roughly once a year with small patches between them. 3.0.0 in October moved the server to Java 17 and Spring Boot 4.1 and began what the project calls Agent First configuration management: structured APIs, user-delegated access and machine-readable capabilities for agents. The 2.5 line before it added incremental config sync and app-level export and import, followed by two permission and authentication patches.
Betaflight grew a real autopilot: waypoint missions, geofence RTH and MAVLink ground control
Betaflight runs two lines at once. The 2025.12.x branch is maintenance: UART interrupt handling, MSP race conditions, failsafe clamping and board-target refreshes. The 2026.6 line, released as 2026.6.1 in August, carries an AUTOPILOT mode with flight plans, CLI waypoint commands, geofence return-to-home and LAND loiter, plus a DroneCAN stack and MAVLink ground control. 2026.6.2 in September backported a single I2C guard fix.

After two years of lowering operating cost (single-process startup, incremental sync, export and import), 3.0 is the first release aimed at a new kind of client: software agents acting on a user's behalf. The platform bump to Java 17 came with it.
Expect 3.0.x patches on the new platform baseline; the entries do not yet show how the agent-facing APIs are used in practice.

The autopilot work is not a single feature but a rebuild of how the firmware handles position: the release notes show position control unified on a velocity primitive and the existing GPS rescue reimplemented as a flight-plan mission rather than a special case. That direction pulls hardware integration along with it — DroneCAN node allocation, GNSS Fix2, ESC telemetry and MAVLink ground-station handshaking are all things a manually flown craft does not need. The SITL harness gained fidelity and per-run session ids in the same releases, which is what you build when autonomous behaviour has to be regression-tested rather than test-flown.
With GPS rescue now running through the mission engine, the next releases on this line should concentrate on hardening that path — the release candidates already added an rx-loss policy, sanity checks and an arming gate for flight plans, and safety scaffolding of that kind usually keeps accumulating after the feature ships.
