Quoi de neuf dans la dernière version ?

• Translation updates: German, Spanish, Japanese, Romanian, Chinese (both zh-Hant and zh-Hans). Thank you, everyone!
• Fresh versions of the APRS device identification database are automatically downloaded from the upstream source - but only when modified.
• Updated the local pre-installed aprs-deviceid database.
• Clean up and vacuum the local target / station cache database periodically. Reduce local disk writes with improved journaling.
• Slightly improved APRS text message fetch scheduling.
• Reworked text message queue/database access in the transmit & fetching scheduler, hoping to fix a few rare crashes.
• DSP AFSK modem: Support transmitting back-to-back frames from the queue (up to 3 at a time). This reduces transmission time, as most packets are small, the txdelay is long, and a lot of time is spent waiting for the next transmission slot.
• A new TNC developer view for people implementing KISS modems: Support sending 1-3 small and 1-2 large packets, back-to-back. Useful for buffering tests and back-to-back packet support. Packets are sent with a "NOGATE" path, which should prevent them from traversing the APRS-IS. Tested with the AFSK modem and the Mobilinkd TNC3 (both seem to support back-to-back transmit and receive correctly).
• Almost all frameworks & dependencies were upgraded to latest versions.
• Built for iOS 18!
