-A low-power sleep mode for the Swift tracker that you can control from the phone, which cuts the power consumption by about a factor of 4. Good for making a small battery last longer between flights. -Lost rocket mode for the Swift tracker. If the Swift lands and doesn't hear from the ground station or the phone for 5 minutes, it starts a sleep/wake cycle that includes a transmission on the original paired tracker channel and the lost & found channel so that other Featherweight trackers can pass along its location. A Swift tracker in lost rocket mode can last longer than 25 hours when using a 400 mAhr battery. -Improved over-the-air firmware updates Bug fixes: -Detect the end of a channel scan -Preserve the Swift channel number when changing channel plans -More reliable voice telemetry -Original tracker channel scan now covers all channels in the original channel plan

New features: -Flight data (10 Hz+) recorded on-board the Swift tracker, with downloading via Bluetooth -Simulated flights for the Swift tracker -The Swift tracker now forwards data from lost original trackers -Updated UI for lost rocket data

-Fixes a bug that prevented the phone from displaying data from an original tracker if the original tracker's name is less than 11 characters. -Improves the download interface with a new widget that shows download progress in all screens No changes to the latest firmware versions Known issues: -The ground station log stops recording data prematurely

New features: Full inter-operability between original ground stations and trackers and Swift ground stations and trackers when using the original channels Fast scanning of all 3 channel plans when using Swift GS Swift tracker scans for an open channel before transmitting Bugs fixed: Swift LoRa comm is more reliable now with improved time synchronization Voice telemetry on original trackers and GS is available again Downloading recorded data is more reliable

Corrected a previous issue where the LoRa status was showing disconnected when it was actually connected. Fixes a bug that can cause a device to erroneously show up as a Blue Raven with serial number 0 when it is re-connected to the phone. Known issues: 1. Voice telemetry is absent 2. In rare cases, if the Swift ground station is Bluetooth-disconnected from the phone and re-connected, it could receive an updated clock time from the phone that is inaccurate enough to cause it to lose sync with the tracker and become LoRa-disconnected. This vulnerability was also present in previous versions. Workaround: Keep the ground station within reach of the phone, especially after the Tracker gets a GPS lock.

New features: -Fixed bugs which could cause loss of synchronization and LoRa communication -Fixed issue with command authorization during connection -New replay feature shows the rocket tilt during the flight for Blue Raven and Blue Jay flight recordings -Fixed tracker page display of LoRa connection status Known issues: -When changing the LoRa channel of an original tracker, the resulting channel does not match the selected channel -Channel scanning in the Channel list is not working for Swift, and stops prematurely when using the original Tracker. -Over-the-horizon relay is not yet supported for the Swift -Simulated flights are not yet supported for the Swift -On-board data recording is not yet supported for the Swift.

Build 466 now supports the new Featherweight Swift with basic tracking functionality. The Swift includes support for the new 240-channel frequency hopping channel plan to reduce LoRa network congestion at large launches The tracking map view now has live telemetry. New firmware included for the Blue Jay and Blue Raven, with controlled BLE transmit power to reduce Bluetooth network congestion at large launches

Corrected the text in the dialog box for the over-the-air updates to show correct was/now on build version

-Provided better on-screen instructions in the event that an over-the-air update gets interrupted

- Support for new sensors in Blue Jay 2 and Blue Raven 2 - Blue Jay and Blue Raven: Default apogee settings now include abort for unstable flights if the rocket tilt exceeds 90 degrees within the first 2 seconds after liftoff - Fixed downloading of tracker and altimeter data from the same flight - Fixed text to speech feature not working on iOS 26 Known issues: The Blue Jay and Blue Raven require a power cycle once after firmware update is complete.

- Fixed an issue where some of the deployment settings thresholds could be displayed and validated incorrectly.

-Includes new firmware for the Blue Jay to correct a bug that would erase both sets of recorded flight data in some circumstances -Improved channel list feature -Improved sequential downloading when multiple devices have data from the same launch -Accel calibration now tolerant to temporary disconnections -My devices list now shows current name and serial number rather than previous version

What's new: -Support for new Blue Jay2 hardware -Axial & lateral acceleration data now included in Blue Jay flight logs -Enhanced GPS tracker channel scanning Bug fixes: -Fixed LoRa packet success rate display -Resolved tracker & ground station pairing issues -Fixed intermittent arming/command issues on Blue Raven & Blue Jay Known issues: - If Blue Jay over-the-air update fails, restart the app and ensure it's the only device powered on. Devices may appear off if the update is interrupted. -Monitoring another user's flights via the channel list can temporarily cause problems re-connecting your ground station to your own tracker.

Click the middle of the screen to get a voice summary of go for launch Deployment settings used in a flight are now automatically included with the flight export Bug fixes: Channel scan now scans all channels Improved Bluetooth connection reliability for trackers and ground stations Improved Bluetooth connection status indications for all devices Fixed an issue preventing OTA updates for the Blue Raven or Blue Jay while connected to a tracker

Reliability improvements to several features: -Data downloads -Command authorization for Blue Raven and Blue Jay -Bluetooth connections to trackers and ground stations -Voice telemetry Known limitations: -Over-the-air updates to the Blue Jay or Blue Raven should be performed with all other Featherweight devices turned off.

Fixed Blue Jay bug that had been corrupting downloaded data in the case where the Blue Jay records until the flash gets full. Includes new Blue Jay firmware. Fixed bug that sometimes prevented command authorization from completing at power-up.

Over-the-Air (OTA) updates which could get stuck in certain situations in the last build are now recoverable with this build.

Improved response to an interrupted Over-the-Air firmware update. Blue Jay avoids attempting to download non-existent high-rate recorded data. New Blue Jay firmware has correct behavior in simulations

Improved interface for Blue Raven Over-the-Air updates. New Blue Raven firmware that prevents commanding by unauthorized phones. The first phone to connect after power-up is automatically authorized. Improved status display for LoRa and Bluetooth connections in the Devices page. Known issues: When using 2 ground stations and 2 trackers simultaneously, the voice telemetry can have a mixture of data from both trackers

Now fully supports multiple simultaneous pairs of ground stations and trackers. Improved calculation of tracker pad altitude offsets Exported data file names now uses launch time rather than download time Corrected label for down received packet counters vs up received packet counters Graphing selections are remembered between sessions Known issues: When flying 2 Blue Ravens together, data from one may need to be re-downloaded separately
